BACKGROUND OF INVENTION
The present invention relates generally to a field-deployable system for the detection and sequencing of emerging infectious diseases or other biological targets, and, more particularly, to a modular, mobile molecular detection, sequencing and analysis laboratory which is configured for storage either in a single backpack or in a footlocker type configuration. The present field-deployable backpack/footlocker system enables local, off the grid molecular detection (qPCR), genomic characterization (DNA & RNA sequencing), and bioinformatics analysis and reporting in the field. The present laboratory system includes an integrated cooling compartment and battery array enabling up to 72 hours of continuous use in the field without access to a conventional power supply.
Emerging viruses such as Zika, Dengue, Yellow Fever and Chikungunya to name a few pose eminent threats to the health and economy of the United States and countries in Central America, South America, Africa, and South Asia. Arbovirus surveillance programs typically rely on a process of field collection of mosquitos en masse, separation of mosquitos into pools, followed by detection and characterization of viruses in fixed laboratories. To a lesser extent, sentinel surveillance programs are also leveraged to serve as controlled monitors of virus exposure. The end-to-end process is labor intensive and time consuming, often leading to a lag time of weeks before an accurate assessment of mosquito populations can be made. Furthermore, typically molecular detection of arboviruses from field samples is by conventional quantitative Polymerase chain reaction (qPCR), the gold standard for sample analysis. However, the laboratory equipment needed for qPCR is specialized, expensive to maintain and requires advance training to operate and interpret the resulting data. qPCR alone does not provide essential genomic data critical for tracking emerging pathogens during an ongoing outbreak. New approaches are needed that minimize the obstacles for effective one-health surveillance and that enable real time tracking of emergent pathogens throughout the world.
While portable DNA sequencing, PCR devices, or other molecular detection equipment allow for the characterization of biological samples in the field due to their small footprint, other logistical equipment must also be transported to the field-site to enable the full utilization of the small footprint molecular hardware. For example, current systems typically require the ability to keep reagents and consumables at their respective storage temperatures, typically 4° C. or −20° C., until use during the course of field exercises. Additionally, computational hardware of substantial power, and often times, an internet connection, is required to run field-forward genomic sequencing devices and to perform the analysis of gigabytes of resulting data. Moreover, various biochemical steps need to be performed to prepare biological samples for molecular detection analyses. A flat, stable workbench area on which to perform these protocols enables optimal sample preparation. Thus, previous field-forward deployments of hand-held/ultra-portable molecular biological detection systems have still required the establishment of a base-of-operations equipped with a stable power source, refrigerators/freezers and/or coolers filled with ice, laptops or desktop computational workstations, folding tables and chairs, and more. Reducing the laboratory footprint of analytical systems to dimensions that could be carried by a single user for operationally relevant time frames has not been accomplished, primarily due to the need for heavy generator-based power required to run cold-chain devices and computational equipment.
It is therefore desirable to develop a field-deployable genomic analysis laboratory that will enable field operators to go from sample to actionable information in the field without the need for an internet connection or reliable power. Designing a field-deployable system with a forward leaning capability for rapid point-of-need analysis of biological targets from potentially any source, environmental or clinical, is needed to enable rapid detection and characterization of harmful biological agents earlier, as well as accelerate the gathering of actionable field data needed for effective bio surveillance and outbreak response. A modular field-deployable laboratory benchtop and analysis system capable of adapting to multiple technologies as they become available for detecting and sequencing biological agents is a key gap that is limiting the full realization of point-of-need molecular biological detection hardware.
SUMMARY OF INVENTION
A solution that addresses the above challenges would be to break with traditional approaches of bringing the sample to the laboratory. Instead, the present “field-deployable system brings the laboratory to the sample” through the development of several embodiments of a modular, mobile laboratory that provides everything needed for field operators to carry out molecular tests directly in the field. The present system brings together multiple simple-to-use technologies in a flexible, common framework that can be adapted quickly to accommodate new technologies as they emerge. The central focus of the present system is to enable advanced molecular detection and genomic characterization that is mobile and can be operated by trained novices in the field.
One embodiment of the present field-deployable system is a configurable, backpack-based mobile laboratory platform with integrated power supply, cold-storage for frozen and chilled critical reagents, and other necessary components for successfully extracting, amplifying, sequencing, and characterizing biological targets such as specific viruses, pathogens and other bacteria from an environmental or clinical sample. The present system uses customized phase-changed cooling solutions to achieve proper storage temperatures for critical reagents and consumables for up to 72 hours during field deployment, without the need for an external power source. This drastically reduces the power requirements for the laboratory footprint as a whole, allowing the use of multiple Li-ION or similar batteries to provide the required power. The present system also includes a solid-state computing system for local analytical needs (for example, bioinformatics), and additional ancillary equipment such as a small centrifuge, sample bead-beating/lysis systems, or thermal cyclers. The present system is designed for achieving the first true “backpack laboratory” and is intended for field use in ruggedized environments.
The solid-state computing system, such as an Intel NUC system with quad-core i7 2.6 GHz processors and 32 GB RAM, is used for local data processing and draws under 60 watts of power at peak load and less than 7 watts when idol. When equipped for Nanopore sequencing, integrated batteries in the present system can power the computational and analytical hardware for 72 hours of nominal usage.
When fully loaded, the present backpack system weighs less than 30 KG, manageable by a single operator. Using rapidly customizable Velcro® inserts or dividers, the present backpack can readily accept sensitive, portable chemical and biological analysis equipment and associated consumables for transport and efficient use in field settings. The present system can provide all necessary hardware, reagents, and consumables to collect the biological sample, extract nucleic acids, prepare Nanopore-ready sequencing libraries, and sequence and analyze resulting data. The present backpack includes an integrated workbench which provides a stable work station in varied terrain. The present system is designed for use in field-forward operational biosurveillance and epidemiology settings, and leverages ultra-portable molecular biology hardware, for example, the Biomeme two3 PCR system, Oxford Nanopore MinION system, and a robust computing platform for rapid local bioinformatics analysis.
Although the specific systems included within the present system could be altered to meet end-user requirements, the present field-deployable backpack system will include and integrate at least the following systems:
1. Reagents and consumables for extraction and purification of nucleic acids from environmental or clinical samples;
2. Rapid PCR-based detection/quantification of target nucleic acids using a system such as the Biomeme two3 qPCR system;
3. Direct sequencing of either amplicon or whole-sample DNA/RNA using a system such as the Oxford Nanopore MinION system;
4. Local data storage and bioinformatics analysis of sequencing data using a bioinformatics pipeline;
5. A cooling compartment for critical lab reagents and/or samples;
6. A Li-ION battery powered source enabling the present mobile laboratory to operate for at least 72 hours.
The present system will be encapsulated in an expedition-style backpack with a hard inner shell suitable for a single operator to carry, unpack, and carry out end-to-end analysis in the field.

DETAILED DESCRIPTION OF THE INVENTION
Referring to the drawings more particularly by reference number wherein like numerals refer to like parts, FIG. 1 illustrates one embodiment of an expedition-style backpack system 10 that is specifically designed to hold each of the required components for accomplishing the detection, amplification, sequencing and analysis of various specific viruses, pathogens, bacteria and other infectious diseases accumulated in the field. The backpack system 10 is a turn-key modular diagnostic laboratory capable of supporting devices for a wide variety of different applications including, but not limited to, point-of-care diagnostics, mobile DNA sequencing, field forensics, environmental monitoring, disease surveillance, and more. The present backpack 10, as will be explained further in detail, includes a plurality of different compartments capable of housing and storing a battery pack array 24 for providing power for at least 72 hours of continuous use, an integrated cooler and freezer system 22, an ultra-mini centrifuge 18, computing and analysis equipment including a local Wi-Fi hotspot, a laptop, storage for a variety of POC devices, a mobile bioinformatics analysis system 26, a PCR system 30, a DNA sequencing system 32, a benchtop workspace 20, pipettes 12, assorted cables, tubes, tips, dry and wet reagents 14, and all other materials necessary for field testing samples taken in the field and for accomplishing the electronic communication between the relevant components.
As best illustrated in FIG. 2, the present backpack 10 will, at a minimum, include various compartments, pouches and other access areas for storing the various components identified in FIG. 2 including storage locations for pipettes and pipette tip boxes 12, storage locations for non-temperature sensitive bottled reagents 14, storage location for a sample tube rack 16, storage location for a mini centrifuge 18, a workbench 20, storage location for phase-change coolants 22, storage location for an appropriate battery array 24, storage location for a mobile bioinformatics analysis system 26 such as the Intel NUC device, appropriate power connections 28 for the bioinformatics analysis system 26 and the mini-centrifuge 18, storage location for the PCR system 30, and a storage location for the DNA/RNA sequencing system 32. It is recognized and anticipated that the backpack 10 may be configured differently than as illustrated in FIG. 2 so long as the necessary equipment as outlined in FIG. 2 can be stored therein in a packed configuration as illustrated in FIG. 1. Other embodiments of the present backpack 10 will be discussed in more detail hereinafter.
The present backpack 10 can likewise be a custom-designed, 3D-printed, heavy duty plastic mold for secure transportation and storage of all necessary materials. This embodiment will be discussed later with respect to FIGS. 7-14. In addition, a 3D printed plastic base plate may likewise be fitted into a custom pack to provide extra support. Rapid PCR-based detection/quantification of target nucleic acids can be accomplished using the Biomeme Two3 qPCR system 30, although other PCR systems may likewise be utilized to target detection of specific viruses, pathogens and bacteria. The Biomeme Two3 system is currently available in the marketplace and can run up to 8 tests on a single charge. The DNA sequencing system 32 can be the Oxford Nanopore MinIon Mk1 system which is a hand-held next generation system which is simple to use and produces rapid turnaround time, less than 3 hours, for direct sequencing of either amplicon or whole-sample DNA/RNA. Here again, other equivalent or comparable DNA/RNA sequencing systems can likewise be used in the present system. The mobile bioinformatics analysis system 26 can be the Intel NUC system which is an ultra-compact, cloud-enabled mobile system which provides local data storage and bioinformatics analysis of sequencing data using a custom bioinformatics pipeline. This solid-state computing platform, which acts as a headless server for bioinformatics analysis and operation of the Nanopore sequence system, produces rapid reporting and uploading of results to cloud based dashboard systems and can likewise monitor cooling system conditions in the cooling compartment and power reserves as will be hereinafter explained. This system will be capable of analyzing the Oxford Nanopore MinIon data in the absence of an internet connection and carries the latest generation of Intel processors and is configured up to 2 TB of storage and 32 GB of RAM allowing rapid, complex phylogeny and genomic characterization of pathogens and other biological select agents and toxins.
The Intel NUC computing platform likewise enables several capabilities not currently available in field-forward molecular detection and diagnostic systems, namely, (1) re-sequencing of amplicons for phylogenetic analysis, (2) detection of pathogens not covered by target assays, and (3) functional characterization of genome-based virulence factors, toxin genes, and antimicrobial resistance markers. In addition, the system will likewise run software for operating the PCR system 30 and the system will comprise a solid-state compact single-board computing system with sufficient storage and compute power to run all the analytical pipelines. The compartments housing the computing platform 26, 30 and 32 will be padded storage compartments.
The battery array 24 can include one or more Li-ION batteries to provide the required power. For example, the battery array could include a military-grade UB12590 set of batteries having a rugged case construction with high energy density (144 Wh/Kg), an operating temperature range between −32° C. to 60° C., and a weight of 1,440 g. It is likewise recognized and anticipated that other battery arrays can likewise be utilized to accomplish the present application.
In addition, the present backpack 10 will include a dedicated hardened cooling compartment for housing the phase-change cooling system 22. The cooling compartment can be segregated into two compartments, one to hold critical lab reagents at 4° C., and one to hold lab reagents at −20° C. These same compartments can also be used to hold and store priority samples after collection requiring cold storage. Maintaining critical cold reagents and samples at 4° C. and/or −20° C. for up to 72 hours is accomplished through the use of phase-change proprietary liquid mixtures. As best illustrated in the phase-change graph illustrated in FIG. 3, solid to liquid phase change of proprietary liquid mixtures keeps the material housed within the cooling compartments at a constant fixed temperature until the phase change is complete. No power input is required to hold the temperature constant.
FIG. 3 represents the phase-change curve of a proprietary liquid mixture. It illustrates the phases that the proprietary material goes through during its transition from a solid to a liquid to a gas. The plateaus on the graph illustrated in FIG. 3, namely, the plateau B-C and the plateau D-E, represent the proprietary material staying at a certain constant temperature until all of the material is converted to the next phase. Since it takes 72 hours for the proprietary material in the present cooling chambers to melt from a frozen solid to completely liquid, the proprietary material will stay at a pre-determined desired selected temperature for that period of time, keeping the reagents and samples either chilled or frozen depending upon which compartment they are housed in. The 72 hours includes the time illustrated in FIG. 3 from A to C on the graph. When the present backpack 10 is about to be deployed to the field, the operator will remove the phase-change material from a refrigerator and/or freezer and will place the material in its appropriate cooling compartment. A different proprietary material is used for each different selected temperature. As soon as the proprietary material is removed from the refrigerator/freezer, it will begin to warm up from point A to point B in FIG. 3 until it reaches its melting temperature. The phase-change material will then stay at its melting temperature until all of the material has melted, that is, from point B to point C in FIG. 3. The total time from point A to point C equals approximately 72 hours. Depending upon the type of proprietary liquid mixture selected, different temperatures can be maintained within the various cooling compartments during a 72 hour operational period. With phase-change cooling and the appropriate battery array, the present backpack can be operated effectively for 72 hours before requiring re-charging of the batteries and re-freezing of the phase-change material.
FIG. 4 illustrates one embodiment of a packed backpack 10 including all of the required components as illustrated in FIG. 2 and discussed above. Using rapidly customizable Velcro-type inserts and/or dividers, the present backpack 10 can readily accept sensitive, portable analysis equipment with associated consumables for transport and efficient use in the field. These divider members can be easily moved and reconfigured to accommodate the necessary equipment housed within the present backpack 10.
FIG. 5 illustrates another embodiment of the packed backpack 10 configured for another application. In this regard, depending upon the particular application, such as water safety testing, food safety testing, environmental biosurveillance, clinical/bed-side diagnostics, forensics and other applications, the present backpack 10 can be reconfigured to carry the necessary equipment for targeting specific pathogens and other biological select agents and toxins.
FIG. 6 is a representative flow chart illustrating one protocol for using the present backpack 10 in the field. Once an operator arrives at the specific field location, traps or other methods are typically set up and/or used for initial capture of the particular pathogen, virus and/or bacteria targeted at step 34 in FIG. 6. This could include blood samples, forensic swabs, soil water plant or animal tissue.
Once the targeted samples are collected, extraction and purification of the targeted pathogens from the samples is accomplished at step 36 using known methods. Once extraction and purification is accomplished, the hand-held PCR unit is used at step 38 to detect and quantify the target pathogen. Once the targeted pathogens are detected and quantified, a series of chemical steps (library prep) are performed at step 40 to ready the extracted nucleic acids for sequencing on the portable NGS (next generation sequencing) device such as the Oxford Nanopore MinIon sequencing unit which takes place at step 42. Once step 42 is accomplished, the compact computing system 26 runs the analysis at step 44 as explained above. The present system 10 is designed to identify the specific virus, pathogen and/or bacteria targeted within two hours and identification of the specific virus, pathogen and/or bacteria genetic sequence can be accomplished within six hours. These times may vary depending upon the particular equipment utilized and the specific targeted virus, pathogen and/or bacteria.
FIGS. 7-14 illustrate still another embodiment 46 of the present field-deployable backpack wherein FIGS. 7-10 illustrate the backpack 46 in its packed configuration and FIGS. 11-14 illustrate the backpack 46 in its unpacked or deployed configuration. As best illustrated in FIGS. 7-10, the present backpacks 46 includes a hardened heavy-duty outer shell 48 which can be made from a plastic molded material, a 3D printing process, or other manufacturing process for providing secure transportation and storage of all of the necessary equipment stored therewithin. The backpack 46 includes an upper storage compartment 50 which is specifically designed for housing the cooling/freezer components of the present system such as the phase-change cooling system 22 previously described, a middle section 52 which houses the PCR detection system 30, the DNA/RNA sequencing system 32, the computing and analysis platform 26, the mini-centrifuge 18, the workbench 20, and all of the necessary ancillary equipment including pipettes 12, reagent bottles 14, tube racks such as tube rack 16, and other equipment and storage compartments. The center section 52 likewise includes a pair of adjustable strap members 54 for allowing a single user to carry the entire backpack 46 as well as a pair of folding and extendable leg members 56 as best illustrated in FIGS. 11 and 12. The leg members 56 support the workbench area 20 and the other compartments associated with the backpack 46 when the backpack 46 is in its unpacked configuration as best illustrated in FIGS. 11 and 12. The leg members 56 can be telescoping in nature or their adjustability can be accomplished using other known methods. It is important that the leg members 56 fold into a tight small configuration as best illustrated in FIG. 10 when backpack 46 is in its packed condition.
The backpack 46 likewise includes a lower compartment 58 which houses the battery array 24 and power converters 60 for converting power from the batteries to the appropriate detection, sequencing and data analysis equipment housed within the backpack 46.
FIGS. 11 and 12 illustrate the present backpack 46 in its unpacked or deployed configuration with leg members 56 pivotally rotated and extended so as to support the entire backpack laboratory including the workbench area 20, upper and lower compartments 50 and 58, and side panels 62 and 64. FIG. 11 illustrates a right side perspective view of the present backpack 46 in its deployed or unpacked configuration showing compartments 50 and 58 positioned adjacent to the workbench area 20 in a substantially horizontal platform with leg members 56 extended and deployed. Upper compartment 50 can be segregated into two separate cooling compartments for holding sequencing reagents and other proper clinical/forensic samples at two separate stored temperatures such as at 4° C. and at a −20° C. Two separate proprietary liquid mixtures, one for each segregated compartment in compartment 50, can be utilized to maintain the two separate storage temperatures. It is also recognized and anticipated that other temperatures could likewise be maintained within the cooling compartments 50 depending upon the particular application and the targeted pathogens.
Lower compartment 58 is also shown in its deployed condition housing battery array 24 and power converters 60. A compartment 66 is located on the right side of the deployed backpack 46 (FIG. 11) for housing the computing and analysis platform 26 such as the Intel NUC platform and server access is provided to compartment 66 via the opening 68 on the right side of the deployed backpack as best illustrated in FIG. 11.
FIG. 12 is a perspective left side perspective view of the deployed or unpacked backpack 46 showing a plurality of compartments for housing other equipment. For example, compartment 70 houses the PCR detection system 30 such as the Biomeme two3 system; compartment 72 houses the mini centrifuge 18; and compartment 74 houses reagent bottles 14. As best illustrated in FIGS. 11 and 12, the side panel or side shroud 62 includes a plurality of Velcro® attachment means 63 for re-positioning the side panel 62 back into its packed configuration as best illustrated in FIGS. 7-10. Side panel 64 likewise includes a plurality of similar Velcro® attachment means 63. It is also recognized and anticipated that side panels 62 and 64 can likewise be opened and closed using zippers or other comparable attachment mechanisms. In this regard, each side panel 62 and 64 is selectively movable between a first position wherein each panel covers at least a portion of the middle section 52 when the backpack member 46 is in its packed configuration, and a second position providing access to the middle section 52.
FIGS. 13 and 14 illustrate the present backpack 46 and its unpacked or deployed configuration with the workbench area 20 removed so as to view the internal compartments housed underneath workbench 20. As clearly shown in FIG. 13, the computing and analysis platform 26 is housed within compartment 66; mini centrifuge 18 is housed within compartment 72; the PCR system 30 such as the Biomeme two3 system is housed within compartment 70; the DNA/RNA sequencing system 32 such as the Oxford Nanopore MinIon system is housed within compartment 76; and the pipettes 12 are housed within compartment 78. The laptop can be stored in external pouches (not shown) which are located on the outside portion of the side panels 62 and 64. Other external storage pockets or compartments can likewise be located along the exterior of the present backpack 46. It is recognized and anticipated that all of the various components discussed above can be housed in different compartments and that the various compartments can be moved and repositioned to other locations within the central section 52, or the components can be housed in external pouches positioned and re-located on the exterior of the backpack 46. Other configurations of the backpack 46 are likewise envisioned and anticipated so long as the backpack is deployable in its unpacked configuration so as to provide a substantially horizontal workbench area or surface such as workbench area 20 for operational use in the field. It is also recognized and anticipated that the upper cooling compartments 50 and the lower compartment 58 can likewise be re-located or repositioned, and it is envisioned that such compartments can be likewise housed within the center section 52. Other configurations of backpacks 10 and 46 are likewise anticipated and envisioned for future use.
Regardless of the specific configuration and location of the various compartments for housing the various required equipment and ancillary materials, it is important that the present backpack either include a workbench area such as workbench area 20, or that the backpack itself is foldable about appropriate hinge means or other foldable mechanisms so as to provide a substantially horizontal workbench area such as workbench area 20 when the present backpack is deployed in its unpacked configuration.
A prototype of the present backpack 10 was field-tested in the Florida Everglades for mosquito surveillance. The present backpack successfully detected and sequenced pathogenic viruses directly from field samples. More particularly, gravid-traps with gravid water were used to capture Culex mosquitos. Battery powered fans drew the mosquitos into a netting where they were trapped. Typically, the physical traps such as a gravid trap for mosquitos is not housed within the present backpack 10, however other materials used for sample collection may be housed in other compartments and side pouches associated with the present backpack 10. Approximately 500 Culex Cedecei mosquitos were collected via light-baited CO2 traps. Bulk RNA/DNA was extracted from sub-sampled 25 mosquito pools using the Biomeme two3 sample extraction kit. RT-qPCR was performed with an assay for VEEV, the parent species of Everglade virus (EVEV), on the Biomeme two3 device. EVEV was detected in one sample (sample 4_1) at a Ct value of 33.92. Sample 4_1 was processed through the GeneReads rRNA depletion kit from QIAGEN to help reduce an abundance of host mosquito reads. The rRNA-depleted RNA was then processed through the RepliG Whole Transcriptome Amplification (WTA) for Single Cells kit. The rRNA-depleted, WTA'd cDNA, was prepped for nanopore sequencing. A total of thirty-three nanopore-generated sequence reads were found to align to the EVEV reference genomes using the sequence alignment software BWA (with nanopore-specific settings). The results of this mapping are set forth in FIG. 15. In the region where both sets of nanopore reads mapped, 7 out of 10 high-quality variants of 100% frequency detected by Illumina sequencing were also detected by nanopore sequencing. This data demonstrates strain-level arbovirus detection using the putatively included Oxford Nanopore MinION with the present invention. Only those variants detected by both Illumina and nanopore sequencing are shown. The ratio in parentheses below each variant is the ratio of Illumina reads containing the variant to Illumina read coverage at the specific location. The number of asterisks after the parentheses indicates how many nanopore reads also contained the same variant.
The present backpack laboratory 10 successfully extracted, amplified, sequenced and characterized viral RNA from a mosquito-pool sample. The protocol used can be run end to end with the total consumables and hardware foot print packed within the present backpack 10 or 46. Basic protocol used in the Florida Everglades test is set forth in FIG. 16. The present backpack laboratory produced sample to answer, including actionable bioinformatics reports, in less than 6 hours. This is presented as an example use-case of the present backpack laboratory and the below discussed footlocker laboratory.
FIGS. 17 and 18 illustrate still another embodiment 80 of a field-deployable mobile laboratory which can be encapsulated or otherwise configured into a footlocker configuration having the same components and capabilities as the field-deployable laboratory 10 and 46 discussed above. FIG. 17 illustrates the footlocker configuration 80 in its unpacked or deployed configuration ready for use whereas FIG. 18 illustrates the footlocker configuration 80 in its packed configuration.
As best illustrated in FIG. 17, the present footlocker laboratory 80 includes a base or box member 82 and a hinged lid member 84, both of which can be made from a wide variety of materials including a hardened heavy-duty plastic material, a wood material, a composite material, or any other suitable material for providing secure transportation and storage of all of the necessary equipment stored therewithin. The footlocker laboratory 80 includes a battery compartment 86 which can be housed in the central portion of the base member 82 as best illustrated in FIG. 17. Here again, the battery compartment 86 is configured to hold and store one or more batteries for powering all of the electrical components stored therein for at least 72 hours of continuous use as previously described.
