     DETAILED DESCRIPTION 
     Disclosed herein are methods of treating or preventing a viral infection by administering an effective amount of a probiotic composition. Further, the probiotic compositions disclosed herein have been found to be advantageous because in described combinations, the probiotic bacteria within the probiotic composition are capable of producing CFUs in the trillions. It is generally understood that the more CFUs available in a probiotic, the more effective the probiotic composition will be at boosting the immune system, supporting the gut health, supporting the limbic system, and providing antibiotic and antiviral effects. The benefits of probiotics are continually being studied; however, the ability of certain combinations of probiotic bacteria strains to produce substantially high CFUs is not known in the art. Finally, kits are described for packaging and transporting the disclosed probiotic compositions. 
     Ranges and Definitions 
     Unless defined otherwise herein, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. Although any methods and materials similar or equivalent to those described herein can also be used in the practice or testing of the present invention, representative illustrative methods and materials are now described. 
     Where a range of values is provided, it is understood that each intervening value, to the tenth of the unit of the lower limit unless the context clearly dictates otherwise, between the upper and lower limit of that range and any other stated or intervening value in that stated range, is encompassed within the invention. The upper and lower limits of these smaller ranges may independently be included in the smaller ranges and are also encompassed within the invention, subject to any specifically excluded limit in the stated range. Where the stated range includes one or both of the limits, ranges excluding either or both of those included limits are also included in the invention. 
     As used herein and in the appended claims, the singular forms “a”, “an”, and “the” include plural referents unless the context clearly dictates otherwise. It is noted that the claims can be drafted to exclude any optional element. As such, this statement is intended to serve as antecedent basis for use of such exclusive terminology as “solely,” “only” and the like in connection with the recitation of claim elements, or use of a “negative” limitation. 
     As used herein, the terms “and/or” and “any combination thereof” and their grammatical equivalents may be used interchangeably. Solely for illustrative purposes, the following phrases “A, B, and/or C” or “A, B, C, or any combination thereof” can mean “A individually; B individually; C individually; A and B; B and C; A and C; and A, B, and C.” 
     As used herein, the term “about” in relation to a reference numerical value and its grammatical equivalents includes the numerical value itself and a range of values plus or minus 10% from that numerical value. For example, the amount “about 10” includes 10 and any amounts from 9 to 11. For example, the term “about” in relation to a reference numerical value can also include a range of values plus or minus 10%, 9%, 8%, 7%, 6%, 5%, 4%, 3%, 2%, or 1% from that value. In some cases, the numerical disclosed throughout can be “about” that numerical value even without specifically mentioning the term “about.” For example, the phrase “about 45 mM, 40 mM, 35 mM,” and so on means “about 45 mM, about 40 mM, about 35 mM,” and so on. 
     As used herein, the term “active” or “activity” for the purposes herein refers to a biological activity of a native or naturally-occurring probiotic molecule, wherein “biological” activity refers to a biological function (either inhibitory or stimulatory) caused by a native or naturally-occurring probiotic molecule. 
     Thus, “biologically active” or “biological activity” when used in conjunction with the probiotic molecules described herein refers to probiotic molecule or amino acid sequence that exhibits or shares an effector function of the native probiotic molecule or sequence. For example, the probiotic molecules described herein have the biological activity of preventing, inhibiting, or treating an enteric viral infection in an animal. 
     By “probiotic” it is generally defined as a live microbial food supplement which beneficially affects the host human or animal by improving its intestinal microbial balance. 
     According to an aspect, isolated probiotic bacteria are provided, the probiotic bacteria being effective in vitro and in vivo to prevent and/or treat viral infection. 
     “Substantially free” herein means less than about 5%, typically less than about 2%, more typically less than about 1%, even more typically less than about 0.5%, most typically less than about 0.1% contamination with other bacteria, yeast, fungi, or mold. 
     As used herein, “treatment” or “therapy” is an approach for obtaining beneficial or desired clinical results. For purposes of this invention, beneficial or desired clinical results include, but are not limited to, alleviation of symptoms, diminishment of extent of disease, stabilized (i.e., not worsening) state of disease, delay or slowing of disease progression, amelioration or palliation of the disease state, and remission (whether partial or total), whether detectable or undetectable. “Treatment” and “therapy” can also mean prolonging survival as compared to expected survival if not receiving treatment or therapy. Thus, “treatment” or “therapy” is an intervention performed with the intention of altering the pathology of a disorder. Specifically, the treatment or therapy may directly prevent, slow down or otherwise decrease the pathology of cellular degeneration or damage, such as due to viral infection, or may render the cells more susceptible to treatment or therapy by other therapeutic agents. 
     The terms “therapeutically effective amount”, “effective amount” or “sufficient amount” mean a quantity sufficient, when administered to a subject, including a mammal, for example a human, to achieve a desired result, for example an amount effective to prevent or treat a viral infection. Effective amounts of the agents described herein may vary according to factors such as the disease state, age, sex, and weight of the subject. Dosage or treatment regimens may be adjusted to provide the optimum therapeutic response, as is understood by a skilled person. 
     Moreover, a treatment regime of a subject with a therapeutically effective amount may consist of a single administration, or alternatively comprise a series of applications. The length of the treatment period depends on a variety of factors, such as the severity of the disease, the age of the subject, the concentration of the agent, the responsiveness of the patient to the agent, or a combination thereof. It will also be appreciated that the effective dosage of the agent used for the treatment may increase or decrease over the course of a particular treatment regime. Changes in dosage may result and become apparent by standard diagnostic assays known in the art. The agents of the present invention may, in aspects, be administered before, during or after treatment with conventional therapies for the disease or disorder in question, such as a viral infection. 
     The term “subject” as used herein refers to any member of the animal kingdom, typically a mammal. The term “mammal” refers to any animal classified as a mammal, including humans, other higher primates, domestic and farm animals, and zoo, sports, or pet animals, such as dogs, cats, cattle, horses, sheep, pigs, goats, rabbits, etc. Typically, the mammal is human. 
     The term CFUs meaning colony forming units is used to describe the amount of probiotic bacteria in the probiotic composition at about time 0 (To) or soon after production of the product. CFUs can also refer to the amount of CFUs listed on packaging of a probiotic composition. Finally, CFUs may refer to the amount of CFUs in the probiotic composition at the end of a 2-year shelf-life. The amount of CFUs may be estimated using a standard algorithm known to those in the industry that produce probiotic compositions. 
     Administration “in combination with” one or more further therapeutic agents includes simultaneous (concurrent) and consecutive administration in any order. 
     “Carriers” as used herein include pharmaceutically acceptable carriers, excipients, or stabilizers that are nontoxic to the cell or mammal being exposed thereto at the dosages and concentrations employed. Often the pharmaceutically acceptable carrier is an aqueous pH buffered solution. Examples of pharmacologically acceptable carriers include buffers such as phosphate, citrate, and other organic acids; antioxidants including ascorbic acid; low molecular weight (less than about 10 residues) polypeptides; proteins, such as serum albumin, gelatin, or immunoglobulins; hydrophilic polymers such as polyvinylpyrrolidone; amino acids such as glycine, glutamine, asparagine, arginine or lysine; monosaccharides, disaccharides, and other carbohydrates including glucose, mannose, and dextrins; chelating agents such as EDTA; sugar alcohols such as mannitol and sorbitol; salt-forming counterions such as sodium; and/or nonionic surfactants such as TWEEN™m, polyethylene glycol (PEG), and PLURONICS™. 
     A “liposome” is a small vesicle composed of various types of lipids, phospholipids, and/or surfactant which is useful for delivery of a drug to a subject, such as a mammal. The components of the liposome are commonly arranged in a bilayer formation, similar to the lipid arrangement of biological membranes. 
     As will be apparent to those of skill in the art upon reading this disclosure, each of the individual embodiments described and illustrated herein has discrete components and features, which can be readily separated from or combined with the features of any of the other several cases without departing from the scope or spirit of the present invention. Any recited method can be carried out in the order of events recited or in any other order that is logically possible.

     EXAMPLES 
     The following non-limiting examples are provided to further illustrate the described embodiments and not to limit the scope of the invention. 
     Example 1: Case Study of Preventing SARS-CoV-2 Infection in Human Subjects 
     A study, conducted in Austria from March 2020-April 2020, showed that the disclosed probiotic compositions were capable of preventing viral infection by SARS-CoV-2. Health Care Personnel, full time doctors and nurses, in contact with those infected with SARS-CoV-2 were provided a probiotic composition to reduce the risk of becoming infected with SARS-CoV-2. 150 healthy female and males with ages ranging from 30 to 75 participated in the study. The probiotic composition comprised  Streptococcus salivrius thermophilus, Lactobacillus delbrueckii,  and  Lactobacillus rhamnosus.  The  Lactobacillus delbrueckii  subspecies  bulgaricus  was used. The probiotic composition was provided in a lyophilizate form (capsule) having a CFU titer of 1.25×10 12 /grams (1.250 trillion/gram or 500 billion CFUs per capsule). The participants took a dose of 1×400 mg HPMC capsule, 3 times daily for at least 30 days. At the 30 day mark, there were no reports of any viral infection, including SARS-CoV-2 within the study group, despite working in a high-risk environment with daily exposure to COVID-19 patients and articles. 
     Example 2: Case Study of Elective Use of the Probiotic Compositions by COVID-19 Patient 
     In early April, 2020, a 50-year-old female was brought to an emergency triage center where she was diagnosed with COVID-19. She was admitted to the Infectious Disease Ward and categorized as “high level of disease severity.” The patient stated that she had started taking probiotics and requested the ability to continue taking them while in the hospital for treatment. The medical professionals confirmed that the ingredients were not known to have counter indications to any of the COVID-19 treatments. 
     For three days, the patient ingested 3 capsules 3 times daily. The capsules were the same as those descried in Example 1 (i.e., 1.250 trillion/gram or 500 billion CFUs per capsule). After the three days, the patient was discharged. The patient followed up with the hospital at one week and two weeks after her discharge. During both of her visits the patient tested negative for SARS-CoV-2. On her second and final visit, it was determined that she was completely clear of COVID-19. 
     Example 3: Case Study of Treating SARS-CoV-2 Infection in COVID-19 Patients 
     In a third study, which took place in Austria, investigators observed that elective use of probiotics to reduce symptoms and treat patients infected with SARS-CoV-2. 62 volunteers made-up of 17 females and 45 males ranging in ages between 37 and 81, were all confirmed to have COVID-19 with symptoms ranging from mild to serious. Based on symptoms, the study included 23 symptomatic outpatients and 39 symptomatic inpatients. The study specifically excluded asymptomatic individuals below 35 years of age. 
     Each patient was provided the same probiotic composition as described in Example 1 (i.e., a composition comprising  Streptococcus salivrius thermophilus, Lactobacillus delbrueckii,  and  Lactobacillus rhamnosus.  The  Lactobacillus delbrueckii  subspecies  bulgaricus  was used. The probiotic composition was provided in a lyophilizate form (capsule) having a CFU titer of 1.25×10 12 /grams (1.250 trillion/gram or 500 billion CFUs per capsule). Each participant took ingested the capsule 3 times daily with a meals. 
     The study participants were monitored weekly. After the first week, 21 patients (33.87%) tested negative for SARS-CoV-2. After the second week, 28 of the remaining 41 patients tested negative for SARS-CoV-2. Within two weeks 79.03% of the patients tested negative after two weeks. This is significant since the recovery rate for non-participants during the same period was 18.4%. During the time period of the study (April 13-27, 2020), the national recovery rate from COVID-19 in Bulgaria was 16.9%, and the worldwide recovery rate was 31.1%. 
     Example 4: Case Study of Preventing and Treating a SARS-CoV-2 Infection in Patients 
     In a fourth study, investigators observe the effects of elective use of a probiotic composition for a first cohort of volunteer patients diagnosed with COVID-19, and a second cohort of volunteers who have not been diagnosed with COVID-19 but have daily exposure risks. 
     The first cohort is provided a probiotic composition comprising  Streptococcus salivrius thermophilus, Lactobacillus  including  delbrueckii, rhamnosus, acidophilus,  and  Lactococcus lactis.  The probiotic composition is provided in a lyophilized, capsule form where each capsule contains 500 billion CFUs. The volunteer patients took ingested a capsules three times a day for one week. The expected results is that the patients taking the probiotic composition will have a higher recovery rate in two weeks-time compared to those similarly situated but not taking the probiotic composition. It is expected that the additional strains in this probiotic composition will have an improved effect on those taking it compared to only three strains. 
     The second cohort is provided the same probiotic composition as the first cohort; however, each capsule contains less than 500 billion CFUs. The volunteers ingest a capsule two to three times a day with meals. The volunteers continue ingesting the probiotic composition for one month. The expected result is that the percentage of second cohort volunteers will have a lower rate of SARS-CoV-2 infection rate than those not taking the probiotic composition who are similarly situated. Further, it is expected that the second cohort of volunteers will have a lower incidence of SARS-CoV-2 infection rate compared to those only taking the three strain composition.
