METHOD OF TREATING A BACTERIAL INFECTION USING COLOSTRUM

BACKGROUND
1. Field

The disclosure of the present patent application relates to a method of treating a bacterial infection by inducing an immune response.

2. Description of the Related Art

The CDC identifies antibiotic resistance as one of the most significant public health challenges of our time. In the United States alone, at least 2 million people are diagnosed with antibiotic-resistant infections annually, and at least 23,000 of these are fatal.

Strategies for developing new treatments have mostly focused on avoiding the rise of antibiotic resistance and on developing new antibiotics. However, avoiding the rise of antibiotic resistance is a failing rearguard action, given the prevalence of antibiotic-resistant bacterial strains. Further, the rate of new antibiotic development has slowed significantly. Most new classes of antibiotics were developed in the 1940s and the 1950s, with only two new classes developed since the year 2000. Antibiotics also have many undesirable side effects, ranging from nausea and diarrhea to liver and kidney damage.

Thus, a method of treating an infection solving the aforementioned problems is desired.

In an embodiment, the colostrum administered may be selected from the group consisting of bovine colostrum, camel colostrum, and a mixture of bovine colostrum and camel colostrum. In an embodiment, the infection is a bacterial infection or an infection caused by bacteria. The bacterial infection may be selected from the group consisting of G+ bacteria and G− bacteria. The bacterial infection may be selected from the group consisting of Staphylococcus aureus subs. aureus Rosenbach (S. aureus), Escherichia coli (E. coli), Pseudomonas aeruginosa (P. aeruginosa), and Methicillin-resistant Staphylococcus aureus (MRSA).

As used herein, a “subject” includes mammals, e.g., humans, dogs, cats, sheep, cows, rats, mice, and the like.

As used herein, the term “about,” when used to modify a numerical value, means within ten percent of that numerical value.

As used herein, “colostrum” is the first form of milk produced by the mammary gland of a mammal just before and/or shortly after giving birth. Colostrum contains maternal antibodies intended to protect the newborn against disease, and frequently contains significantly more protein than non-colostrum milk.

In an embodiment, the colostrum may be collected after parturition and stored at −20° C. for at least a week. In an embodiment, the colostrum may then be thawed at −4° C. for at least 8 hours, and then lyophilized. In an embodiment, the lyophilized colostrum may then be suspended in sterilized saline solution at a concentration of 28 g lyophilized colostrum per liter of sterilized saline solution, forming a colostrum composition for use as discussed herein. In an embodiment, a colostrum composition may include bovine colostrum, camel colostrum, or a mixture of bovine colostrum and camel colostrum. An embodiment of the present subject matter may include the colostrum composition including at least a mixture of one of the bovine colostrum and the camel colostrum and a pharmaceutically acceptable carrier.

In an embodiment, the administration of colostrum or a colostrum composition of the present subject matter may include daily administration. In an embodiment, the daily administration may be administered in the early morning hours. In an embodiment, administration of colostrum or a colostrum composition of the present subject matter may include injecting one ml of a solution of 28 g lyophilized colostrum per liter of sterilized saline solution every day at eight in the morning for at least a month.

In an embodiment, the cytokines may be selected from the group consisting of Interferon-γ (IFN-γ), Tumor Necrosis Factor α (TNF-α), and Interleukin-10 (IL-10).

An embodiment of the present subject matter is directed to a pharmaceutical composition comprising the mixture of bovine and camel colostrum and a pharmaceutically acceptable carrier.

An embodiment of the present subject matter is directed to a method of making a pharmaceutical composition, including mixing an effective amount of the bovine and camel mixture colostrum with a pharmaceutically acceptable carrier. For example, the method of making a pharmaceutical composition can include mixing the colostrum under sterile conditions with a pharmaceutically acceptable carrier, preservatives, buffers, and/or propellants to create the pharmaceutical composition. In an embodiment, the pharmaceutical composition may be natural and/or organic and the pharmaceutically acceptable carrier may also be natural and/organic.

To prepare the pharmaceutical composition, at least one of the bovine colostrum and camel colostrum, as the active ingredient, is intimately admixed with a pharmaceutically acceptable carrier according to conventional pharmaceutical compounding techniques. Carriers are inert pharmaceutical excipients, including, but not limited to, binders, suspending agents, lubricants, flavorings, sweeteners, preservatives, dyes, and coatings. In preparing compositions in oral dosage form, any of the pharmaceutical carriers known in the art may be employed. For example, for liquid oral preparations, suitable carriers and additives include water, glycols, oils, alcohols, flavoring agents, preservatives, coloring agents, and the like. Further, for solid oral preparations, suitable carriers and additives include starches, sugars, diluents, granulating agents, lubricants, binders, disintegrating agents, and the like.

The present compositions can be in unit dosage forms such as tablets, pills, capsules, powders, granules, ointments, sterile parenteral solutions or suspensions, metered aerosol or liquid sprays, drops, ampules, auto-injector devices or suppositories, for oral parenteral, intranasal, sublingual or rectal administration, or for administration by inhalation or insufflation. The active compound can be mixed under sterile conditions with a pharmaceutically acceptable carrier and, if required, any needed preservatives, buffers, or propellants. The composition can be presented in a form suitable for daily, weekly, or monthly administration. The pharmaceutical compositions herein will contain, per dosage unit, e.g., tablet, capsule, powder, injection, teaspoonful, suppository and the like, an amount of the active ingredient necessary to deliver an effective dose. A therapeutically effective amount of the colostrum compositions or an amount effective to treat a disease, such as a bacterial infection, may be determined initially from the Examples described herein and adjusted for specific targeted diseases using routine methods.

The colostrum or colostrum compositions can be administered to a subject in need thereof. For example, the colostrum or colostrum compositions can be used to treat a subject suffering from a bacterial infection. The bacterial infection can be caused by E. coli, P. aeruginosa, S. aureus, MRSA, or the like.

An embodiment of the present subject matter is directed to a method of treating a bacterial infection, comprising administering to a subject in need thereof a therapeutically effective amount of the pharmaceutical composition according to the present subject matter. In an embodiment, the pharmaceutical composition may be organic.

The colostrum or pharmaceutical compositions thereof can be administered to a subject by any suitable route. For example, the colostrum or pharmaceutical compositions can be administered orally (including buccally and sublingually), nasally, rectally, intracisternally, intra-vaginally, intraperitoneally, topically, transdermally (as by powders, ointments, or drops), and/or parenterally. As used herein, “parenteral” administration refers to modes of administration other than through the gastrointestinal tract, which includes intravenous, intramuscular, intraperitoneal, intrasternal, intramammary, intraocular, retrobulbar, intrapulmonary, intrathecal, subcutaneous and intraarticular injection and infusion. Surgical implantation may also be contemplated, including, for example, embedding a composition of the disclosure in the body such as, for example, in a tissue, in the abdominal cavity, under the splenic capsule, brain, or in the cornea.

Accordingly, the route of administration can include intranasal administration, oral administration, inhalation administration, subcutaneous administration, transdermal administration, intradermal administration, intra-arterial administration with or without occlusion, intracranial administration, intraventricular administration, intravenous administration, buccal administration, intraperitoneal administration, intraocular administration, intramuscular administration, implantation administration, topical administration, intratumor administration, and/or central venous administration.

The following examples illustrate the present teachings.

Example 1
Determining the Lethal Dose and Optimum Route of Infection for Four Gram-Positive and Gram-Negative Bacteria in a Rat Model

The ethical committee of King Saud University provided prior approval before any animal studies were commenced. All animals were fed with standard laboratory rat chow (Basal diet 5755, PMI Nutrition International, Inc., Richmond, Calif., USA) according to the National Institute of Health guidelines. Rats were quarantined for six days before commencing experiments. Chemical restraint anesthesia was achieved using injectable sedation, such as a Ketamine/Xylazine mix administered subcutaneously.

The Riyadh Military Hospital Bacteriology Laboratory provided American Type Culture Collection (ATCC) Escherichia coli (E. coli) (ATTC 25922). The bacterium is Enteropathogenic E. coli (EPEC) but not Enterotoxigenic E. coli (ETEC). It does not produce verotoxin and is used for media testing and as a negative control for LT toxin production. This organism is a CLSI control strain for antimicrobial susceptibility testing. Other bacterial strains obtained from the same source include Staphylococcus aureus subsp. aureus Rosenbach (S. aureus) (ATCC 29213), Methicillin-resistant Staphylococcus aureus (MRSA) (ATCC 12498), Pseudomonas aeruginosa (P. aeruginosa) (ATCC 27853).

Bacterial propagation was performed in Trypticase Soy Broth (TSB) for seven hours at 26° C., and stock aliquots were frozen at −79° C. until used. A frozen stock sample was thawed and plated onto Trypticase Soy Blood Agar plates in preparation for a bacterial inoculum lethal dose trial using rats injected subcutaneously and intravenously. The results of this trial are compiled in Table 1 and Table 2 below.

Virus and antibody-free male Wistar rats were acquired from the Pharmacy College of King Saud University. Animals were housed up to 6 animals in a cage. Male Wistar rats (n=118) weighing 190-300 g were randomly selected to receive either intravenous (i.v.) or intraperitoneal (i.p.) injection with either E. coli or one of the other three studied bacteria (n=20-40 per group). Control rats were kept in a separate compartment. Animals were observed after bacterial injection to record the number of dead animals. The results are summarized in Table 1. At six hours after bacterial administration through either injection route, animals appeared weak and lethargic. Estimated lethal doses of each pathogenic microbe were determined as shown in Table 2. In summary, the optimized lethal doses were determined to be ˜6×10⁸/ml Colony Forming Units (CFU) for E. coli, 9×10⁸/0.5 ml CFU S. aureus, ˜9.5×108/0.5 ml CFU P. aeruginosa, and 12×10⁸/1.5 ml CFU MRSA. The i.v. route of administration was preferred for all microbes.

Determining Effect of Camel Colostrum, Bovine Colostrum, and a Mixture of Camel Colostrum and Bovine Colostrum on Survival of Rats Infected with Gram-Positive and Gram-Negative Bacteria

Three types of colostrum were used from different sources. Camel colostrum was sourced from 10 healthy individual camels (Camelus dromedarius) that were chosen randomly (average age, six years) from the Conservation and Genetic Improvement Center in Al-karj, Saudi Arabia. Samples were obtained manually from all camels' udders and were collected immediately after parturition.

Bovine colostrum samples were sourced from 10 healthy Holstein cows (average age, 3.8 years) provided by the Almarai Company. The Immunology Lab, King Khaled Hospital, Medicine College, King Saud University Hospital, collected the samples and confirmed that the source cows were in good health and had no clinical evidence of mastitis or tuberculosis, delivered healthy full-term infants, and had not consumed medications within one week before collection.

The colostrum samples were collected using the following protocol: 20 samples collected at the first-day parturition after thorough hand washing and cleansing of the breast and nipple with soap and tap water. Milk samples were expressed manually into sterile Erlenmeyer flasks, pooled, dispensed into sterile test tubes and stored on at −20° C.

The study included a control group with no graft contamination and no antibiotic prophylaxis (Group 1), a bacterial treatment group (Group 2), a colostrum treatment group (Group 3), and a bacterial treatment and colostrum treatment group (Group 4). (See Table 3) Group 3 included three different sub-groups, designated camel colostrum, bovine colostrum, and mix colostrum. One ml of prepared colostrum solution (28 g lyophilized colostrum/liter sterilized saline solution (w/v)) was administered by intraperitoneal injection every day early in the morning for 30 days.

The rats of Group 2 and Group 4 were then anesthetized with chloroform or ether and injected intravenously with the recommended lethal dose of one of the studied bacteria in the tail vein. Survival rates in each group were observed for two weeks after injection.

Pseudomonas aeruginousa ATCC27853

Staphylococcus aureus ATCC12498

Methicillin-resistant Staphylococcus aureus ATCC12498

The lethal dose of each bacterium established in Table 1 was administered intravenously once

in the tail vein of each rat using a 14-gauge needle at eight AM on the starting day.

Group 3
Colostrum groups: Three colostrum sub-groups were designated:

Camel Colostrum

Bovine Colostrum

Mix Colostrum

One ml of prepared colostrum solution (28 g lyophilized colostrum/liter sterilized saline

solution (w/v)) was injected i.p. daily at eight AM for 30 days.

Group 4
Bacterial and Colostrum groups: Sub-groups were designated for all possible combinations

of Group 2 and Group 3.

At zero time up to one month and after inoculation with the four studied bacteria and induction by colostrum as in Table 4 and Table 5, animals appeared weak and lethargic with the microbial treatments. In controls without bacterial treatment, camel colostrum, bovine colostrum, and mix (a mixture of both camel and bovine colostrum) produced a similar survival rate without evidence of concentration of disease (See Table 4). Compared with the control treatment, bacterial treatment with colostrum improved mortality rates associated with the bacterial variable and route of treatment. These animals lived through one month of observation. The death of animals started from the second day until the 22^ndday, with most deaths occurring in the administrated pathogenic bacteria only group (Group 2). As shown in Table 4, the fastest and the best-protected treatment was lethal S. aureus with 50-100% mortality.

Moreover, 100% of rats injected with S. aureus and vaccinated i.p. by one of the three types of colostrum survived. Camel colostrum had a tremendous protective effect from lethal MRSA, converting 100% mortality to 100% survival. Camel and bovine colostrum enhanced survival against lethal P. aeruginosa from 0% to 33% survival in the former and from 50% to 66% survival in the latter (see Table 4). Lethal E. coli caused 84% mortality, and camel colostrum enhanced survival of up to 83%. On the other hand, mixed colostrum also enhanced survival, up to 50%.

Example 3
Determining Effect of Camel Colostrum, Bovine Colostrum, and a Mixture of Camel Colostrum and Bovine Colostrum on Percentage Change in Weight of Rats Infected with Gram-Positive and Gram-Negative Bacteria

The effect of the treatment on the percentage change of the weight of rats (grams) for each studied pathogenic bacterium was determined using three types of colostrum; Camel, Bovine, and Mix. The results of this experiment are illustrated in Table 5 and Table 6. The range of percent change in the weight of healthy rats was revealed in minimum and maximum (Min 10%-Max 29%) through one month of observation. Camel colostrum and Mix colostrum induced a remarkable 6%-59% increase in the weight of rats. Bacterial injections dramatically decreased the percent weight change in rats from −12% to 12%. The most notable max increase values in percent change of weight of rats after colostrum treatment were observed when comparing the weight of rats infected with MRSA alone with the weight of the rats treated with mix colostrum. Mix colostrum induced 43% change in the weight of rats compared to −21% weight change in rats injected with a lethal dose of MRSA alone.

Example 4
Effect of Infection and/or Colostrum on Expression of Three Cytokines in Rats

For circulating blood analysis, animals were anesthetized with an ether mask. Circulating levels of IFN-γ, IL-10, and TNF-α were measured in serum samples of all rats obtained from the eye vein. Blood samples were collected in heparinized syringes to assess cytokine level assessed of IFN-γ, IL10, and TNF-α. Serum concentrations of each cytokine were monitored at 0 days post-treatment, 24 hours post-treatment, 7-25 days post-treatment (midpoint or Mid), and 30 days post-treatment (Last or Final) by ELISA. Briefly, blood samples (2 ml) were centrifuged for 10 minutes at 3500 rpm, at 4° C., and the serum samples were kept at −20° C. in a freezer until examined. Commercial reagents used to identify individual cytokines included Quantikine® ELISA, Rat TNF-α Immunoassay, Catalog Number RTA00, Quantikine® ELISA, Rat IL-10 Immunoassay, Quantikine® ELISA, and Rat IFN-γ Immunoassay. These kits were used according to the manufacturer's recommendations (USA & Canada R&D Systems, Inc. Minneapolis). The limits of sensitivity of the assay were determined to be five pg/ml for TNF-α and ten pg per ml for IFN-γ and IL-10, respectively. The intra- and inter-assay coefficients of deviation were less than 5% and 10%, respectively.

Quantitative data were statistically represented in terms of minimum, maximum, and median. A comparison between different groups in the present study was done using the Kruskal-Wallis test to compare between more than two nonparametric groups.

Correlation between various variables was determined using Spearman rank correlation coefficient (R) with graph representations using linear regression.

A probability value (p-value) less than or equal to 0.05 was considered significant. All statistical analyses were performed using statistical software SPSS (Statistical Package for Social Science) statistical program version 16.0. Graphs were created using SPSS statistical program version 16.0 with Microsoft Excel program version 2010.

Initial results for IFN-γ expression as a measure of the immune response in the presence of colostrum, E. coli, or E. coli and colostrum are presented in Table 7 and FIG. 1.

Data from the full month-long experiment are presented in Table 8 and FIGS. 2A-2C. In the model of E. coli bacterial infection treated with either bovine colostrum or with the mixed colostrum, IFN-γ elevated up to 0.12 pg/ml in the mixed colostrum treatment group but was 0.06 pg/ml in the bovine colostrum treatment group. At the end of the trial (Last) IFN-γ exhibited a steady level of the immune response in the mixed colostrum treatment group (93.750 pg/ml) as well as the bacterial infection and mixed colostrum treatment group. (See Table 8). This experiment confirms the synergistic effect of mixed colostrum, as it triggers a more significant immune response than bovine colostrum or camel colostrum alone.

In the model of E. coli bacterial infection, both camel colostrum and mixed colostrum stimulated TNF-α. The highest enhancement was for camel colostrum in all treatments (0.56 pg/ml, 0.57 pg/ml, and 0.60 pg/ml for colostrum alone, bacteria alone, and colostrum with bacteria, respectively). These results are summarized in Table 9 and FIG. 3. Data from the full month-long experiment are presented in FIGS. 4A-4C.

In the model of E. coli bacterial infection, mixed colostrum alone triggered the IL-10 immune response more than the other treatments (83.30 pg/ml). The most enormous increase was observed in the presence of mixed colostrum and E. coli bacteria (1000.0 pg/ml at the Last point). (See Table 10 and FIG. 5)

In the model of MRSA infection, the administration of a lethal dose of MRSA also raised IFN-γ levels to 78.13 pg/ml when treated with mixed colostrum and bacteria. These results are similar to the IFN-γ levels reported above for rats administered a combination of mixed colostrum and S. aureus of 78.10 pg/ml. This result compares favorably to the IFN-γ levels reported for rats administered Bovine Colostrum and S. aureus of 23.76 pg/ml. Thus, these results confirm the improved immune response to treatment with mixed colostrum. The MRSA experimental results are summarized in Table 23 and FIG. 19. The month-long MRSA experimental results are summarized in Table 24 and FIGS. 20A-20C.

Overall, the S. aureus lethal dose experiments confirm that treatment with bovine colostrum resulted in lower stimulation of immune system cytokines than other tested treatments. For example, both the administration of colostrum mix alone and the administration of colostrum mix and the lethal dose of bacteria resulted in the same increase in IL-10 levels (83.30 pg/ml compared to administration of bacteria alone at 0.07 pg/ml) Administration of mixed colostrum alone and administration of mixed colostrum and bacteria raised IL-10 levels to 166.63 pg/ml at days 7-25 (M) and to 750.00 pg/ml by the final day of the experiment. Both camel colostrum and mixed camel colostrum and bovine colostrum stimulated TNF-α levels. The most enormous change was for camel colostrum in all treatments, which resulted in 0.56 pg/ml, 0.50 pg/ml, and 1.21 pg/ml for colostrum alone, bacteria alone, and colostrum and bacteria respectively.

Example 5
Calculating Correlations Between the Studied Cytokines and the Colostrum Sources

The immunomodulatory effect of pro-inflammatory cytokines varied depending upon the bacterial species tested. IFN-γ exhibited a steady level of immune response in mixed colostrum treatment (93.750 pg/ml in the E. coli model). In the S. aureus model, IFN-γ levels increased to 78.10 pg/ml when the mixture of colostrum was administered compared to 17.82 pg/ml in the control colostrum. In the MRSA experiments, IFN-γ levels increased to 78.13 pg/ml when the mixed colostrum was administered. TNF-α, in the P. aeruginosa experiments showed the most considerable change in level when camel colostrum and bacteria were administered (8.931 pg/ml after 24 hours compared to 1.171 pg/ml for bacterial injection only).

IL-10 is a crucial cytokine marker. In E. coli treated with mixed colostrum, IL-10 was elevated to 83.30 pg/ml compared to 31.62 pg/ml when bacteria alone were administered. Early cytokine transcriptional changes could be useful as a forecasting tool. IL-10 started to increase after 24 hours in the E. coli experiments, up to 80.3080 pg/ml. In S. aureus administered mixed colostrum and bacteria, IL-10 levels rose to 166.60 pg/ml after 7-25 days, and this increase was sustained over time and ended with 750.00 pg/ml after one month.

The best survival effect was in camel colostrum and mixed colostrum for all the tested bacteria (83% in E-coli—100% in MRSA) in the infected rats in the presence of colostrum.

Camel colostrum and mixed colostrum blocked adherence of bacteria to cultured tissue cells. Mixed colostrum (bovine colostrum and camel colostrum) can stimulate the immune response more than the bovine colostrum or camel colostrum alone. Colostrum has been shown to be a constant source of potentially probiotic bacteria in an infant's gut, including staphylococci, streptococci, and lactic acid bacteria. The immunomodulatory effect of pro-inflammatory cytokines varied due to the bacterial species.

IL-10 and IFN-γ showed a significant interaction at 24 hours. The significant elevations of the IL-10 and TNF-α transcriptional levels most likely indicate their essential role in the regulation of the immune responses of the bovine mammary gland in S. aureus infection. That could reflect the suppressive nature of the S. aureus mastitis. Early cytokine transcriptional changes could be useful as a forecasting tool in the detection of the subclinical S. aureus mastitis. The transcriptional patterns of these cytokines in the early stages of S. aureus infection could help to unravel their role in the pathophysiology of S. aureus mastitis. Finally, vital, crucial cytokine marker(s) could emerge that provide efficient diagnostic and therapeutic means for the early detection of S. aureus mastitis. Early cytokine transcriptional changes could be useful as a forecasting tool in the detection of the subclinical S. aureus mastitis.

These experiments demonstrate that camel colostrum, bovine colostrum and mixed colostrum (bovine and camel colostrum) can provide protective and immune-stimulatory effects against the studied pathogenic bacteria in vitro and in vivo. The lyophilized colostrum derivative studied maintained most of the bioactive factors that appear to be at the basis of its many nutritional, modulatory, or even therapeutic, applications.

The fastest and the best-protected treatment was for lethal S. aureus with a baseline of 50-100% mortality. 100% survival was obtained for all six rats injected with S. aureus and administered the three types of colostrum by i.p. injection. Camel colostrum had a tremendous protective effect from lethal MRSA, demonstrating 100% survival versus 100% mortality in MRSA administration alone. Also, MRSA showed the highest maximum increased values in % change in weight of rats administered mixed colostrum (43% compared to −21% for rats administered only the lethal dose of MRSA).

Camel colostrum and mixed colostrum alone induced a remarkable increase in the weight of rats ranging from (6%-59%). Bacterial injection led to a dramatic decrease in the percent weight change in rats from −12% to 12%. MRSA demonstrated the most significant maximum increased values in percent change of weight of rats treated with mixed colostrum (43% compared to −21% when administered MRSA alone).

Calculations of the correlation between IFN-γ, IL-10, and TNF-α are summarized in Tables 29-31. Table 29 shows that without the presence of Colostrum, the value of the correlation coefficient between IL-10 and TNF-α was −0.773**, indicating a significant negative strength of association, while the value of the correlation coefficient between IFN-γ and TNF-α was 0.464*, demonstrating a less significant positive strength of association. With the presence of Colostrum, the only significant value of the correlation coefficient was 0.647**, between IL-10 and IFN-γ. In the absence of Colostrum, the administration of bacterial strains did not demonstrate a significant value of the correlation coefficient between the three tested cytokines in gram negative E. coli and P. aeruginosa; however, gram-positive S. aureus and MRSA has significant values of the correlation coefficient between IL-10 and IFN-γ. In the presence of both Colostrum and bacterial strains, the correlation coefficient between IL-10 and IFN-γ demonstrated a positive strength of association for S. aureus (0.701*) and MRSA (0.503*). Further, in the presence of E. coli, the correlation coefficient between IL-10 and TNF-α had a significant negative strength of association (−0.470*).

Table 30 shows the correlation between IFN-γ, IL-10, and TNF-α in the presence of Colostrum when treated with S. aureus or MRSA. A significant value of a correlation coefficient was observed in the presence of Camel Colostrum, with the coefficient between IL-10 and TNF-α having a negative strength of association for S. aureus of −0.517** and for MRSA of −0.585**. A significant value of a correlation coefficient was observed in the presence of Bovine Colostrum, with the coefficient between IFN-γ and TNF-α having a positive strength of association for S. aureus of 0.415* and for MRSA of 0.551**. A number of significant values of correlation coefficients were observed in the presence of Mixed Camel and Bovine Colostrum, with the coefficient between IFN-γ and IL-10, IFN-γ and TNF-α, and IL-10 and TNF-α all having respective positive strength of association for S. aureus of 0.659**, 0.694**, and 0.439*. For MRSA, the coefficient between IFN-γ and IL-10 also showed a positive strength of association of 0.512**.
