[0002] Animals, including humans, harbor a multitude of microbes (collectively referred to as the microbiota) in anatomical locations including the mouth, esophagus, stomach, small intestine, large intestine, caecum, vagina, skin, nasal cavities, ear, and lungs. The human microbiota is responsible for a multitude of critical processes, including the development of the immune system, metabolism of carbohydrates, proteins and xenobiotics, formation and regeneration of the epithelium, fat storage, production of hormones, production of vitamins, and protection from pathogen in- fections, among others (See e.g., LeBlanc et al. Curr. Opin. Biotechnol. (2013) 24(2):160-168; Hooper et al. Science (2012) 336(6086):1268-1273; Hughes et al. Am. J. Gastroenterol. (2013) 108(7):1066-1074). Modification of the human microbiota, which can be caused by a number of factors such as antibiotic use, excessive hygiene, diet, genetic background or combinations of the above, has been associated with a number of unwanted effects including the occurrence of infectious diseases (e.g., C. difficile infections), inflammatory, autoimmune and allergic diseases (e.g., ulcerative colitis, Crohn's disease, Type I diabetes, food allergies, asthma, rheumatoid arthritis) and metabolic diseases (e.g., Type II diabetes, metabolic syndrome, obesity, mal- . nutrition), and cancer, among others. For instance, modifications of the microbiota can lead to a loss of tolerance against harmless food antigens or commensal bacterial antigens, subsequent excessive inflammatory responses, metabolic dysregulation, and damage to the intestinal tissue, which compromises its ability to serve as a barrier between the gut lumen and the systemic circulation. Manipulation of the immune response is of great importance in the treatment of cancer and in vaccination. Cancer therapies that target the immune system have attained improvements in survival rates. However, a large percentage of patients do not respond to cancer immunotherapies. Similarly, large population subsets (e.g., the elderly) cannot mount strong immune responses to vaccines. Approaches for countering the harmful effects of microbiota modifications on health are limited, despite the role that such modifications play in promoting human pathology. Interventions known to modulate the microbiota include antibiotics, prebiotics, probiotics and fecal transplants, each of which has limitations and potential adverse effects. Additional approaches to counter the detrimental effects of mi- crobiome modification on human health are clearly needed. Furthermore, approaches for promoting stronger immune responses to cancer and to vaccines are also needed. Summary of Invention The inventors joined the Innovative Advanced Research and Development Support Project Incubation Type of Japan Agency for Medical Research and Development (AMED) in 2016, whose Research and Development Subject entitled "Creating New Drugs Using Intestinal Bacterial Strain Cocktail" (AMED-LEAP Research Program), and obtained the present invention as the result of the AMED-LEAP Research Program. The disclosure relates to compositions of bacterial strains and methods for the induction and / or proliferation of CD8+ T-cells by administering these com- positions. The disclosure also provides compositions and methods for the treatment of diseases that can be treated by the induction and / or proliferation of CD8+ T- cells. Diseases that can be treated by the induction and / or proliferation of CD8+ T- cells include infectious diseases and cancers. As disclosed herein, for the first-time compositions of human-derived bacterial strains are provided which activate the immune system through the induction of in- terferon gamma producing CD8+ T cells (also referred to herein as IFNy+CD8+ T cells, CD8+ IFNy+T cells, CD8+ T cells or CD8 positive T-cells). While microbial- based compositions for inducing proliferation or accumulation of regulatory T-cells (WO2011 / 152566), and composition for inducing Th17 cells (WO2015 / 156419) were previously reported, this disclosure is the first report on microbial species which induce IFNγ+CD8+ T-cells. IFNγ+CD8+ T-cells play important roles in the immune system, in particular the surveillance of infections (e.g., viral infections) and cancer cell development. The compositions provided herein can therefore be used in, for instance, the treatment of infectious diseases and cancer immunotherapy.

[0120] DETAILED DESCRIPTION Provided herein are compositions and methods for the induction and / or proliferation of CD8+ T-cells, and methods for the treatment of diseases and conditions that can be treated through the induction and / or proliferation of CD8+ T-cells, including infectious diseases and cancers. In one aspect, the disclosure provides compositions comprising one or more bacterial strains with unique biological properties. In one aspect, the compositions of the bacterial strains disclosed herein, also referred to as bacterial compositions, can induce the proliferation and / or accumulation of CD8+ T-cells. In one aspect, the com- positions of the bacterial strains disclosed herein can induce the proliferation and / or ac- cumulation of CD8+ T-cells.

[0121] In one aspect, the bacteria of the compositions disclosed herein can be identified by their 16S rRNA (or 16S rDNA) nucleic acid sequence. In general, bacteria are classified as belonging to a specific species and / or genus based on their 16S rRNA nucleic acid sequence. Bacteria, such as bacteria derived from the microbiome, may also be classified into phylogenetic clusters with other closely related strains and species. (See e.g., Rajilic-Stojanovic, M., and de Vos, W.M. (2014). The first 1000 cultured species of the human gastrointestinal microbiota. FEMS Microbiol Rev 38, 996-1047).

In one aspect, the disclosure provides bacterial strains with 16S rDNA sequences that have homology to a nucleic acid sequence of any one of the sequences of the bacterial strains or species described herein. In some embodiments, the bacterial strain has at least 60%, at least 70%, at least 80%, at least 81%, at least 82%, at least 83%, at least 84%, at least 85%, at least 86%, at least 87%, at least 88%, at least 89%, at least 90%, at least 91%, at least 92%, at least 93%, at least 94%, at least 95%, at least 96%, at least 97%, at least 98%, at least 99%, at least 99.5%, at least 99.6%, at least 99.7%, at least 99.8%, at least 99.9%, or up to 100% homology relative to any of the strains or . . . bacterial species described herein over a specified region or over the entire sequence. It would be appreciated by one of skill in the art that the term "homology" or "percent homology," in the context of two or more nucleic acid sequences or amino acid sequences, refers to a measure of similarity between two or more sequences or portion(s) thereof. The homology may exist over a region of a sequence that is at least about 50 nucleotides in length, or more preferably over a region that is 100 to 500 or 1000 or more nucleotides in length. In some embodiments, the homology exists over the length the 16S rRNA or 16S rDNA sequence, or a portion thereof. Additionally, or alternatively, two or more sequences may be assessed for the identity between the sequences. The terms "identical" or percent "identity" in the context of two or more nucleic acids or amino acid sequences, refer to two or more sequences or subsequences that are the same. Two sequences are "substantially identical" if two sequences have a specified percentage of amino acid residues or nu- cleotides that are the same (e.g., at least 80%, 85%, 90%, 95%, 96%, 97%, 98%, 99%, 99.5%, 99.6%, 99.7%, 99.8% or 99.9% identical) over a specified region or over the entire sequence, when compared and aligned for maximum correspondence over a comparison window, or designated region as measured using one of the following sequence comparison algorithms or by manual alignment and visual in- spection. Optionally, the identity exists over a region that is at least about 50 nu- cleotides in length, or more preferably over a region that is 100 to 500 or 1000 or more nucleotides in length. In some embodiments, the identity exists over the length the 16S rRNA or 16S rDNA sequence. Additionally, or alternatively, two or more sequences may be assessed for the alignment between the sequences. The terms "alignment" or percent "alignment" in the context of two or more nucleic acids or amino acid sequences, refer to two or more sequences or subsequences that are the same. Two sequences are "substantially aligned" if two sequences have a specified percentage of amino acid residues or nu- cleotides that are the same (e.g., at least 80%, 85%, 90%, 95%, 96%, 97%, 98%, 99%, 99.5%, 99.6%, 99.7%, 99.8% or 99.9% identical) over a specified region or over the entire sequence, when compared and aligned for maximum correspondence over a comparison window, or designated region as measured using one of the following sequence comparison algorithms or by manual alignment and visual in- spection. Optionally, the alignment exists over a region that is at least about 50 nu- cleotides in length, or more preferably over a region that is 100 to 500 or 1000 or more nucleotides in length. In some embodiments, the identity exists over the length the 16S rRNA or 16S rDNA sequence. For sequence comparison, typically one sequence acts as a reference sequence, to which test sequences are compared. Methods of alignment of sequences for comparison are well known in the art. See, e.g., by the local homology algorithm of Smith and Waterman (1970) Adv. Appl. Math. 2:482c, by the homology alignment algorithm of Needleman and Wunsch, J. Mol. Biol. 48:443, 1970, by the search for similarity method of Pearson and Lipman. Proc. Natl. Acad. Sci. USA 85:2444, 1988, by computerized implementations of these algorithms (GAP, BESTFIT, FASTA, and TFASTA in the Wisconsin Genetics Software Package, Genetics Computer Group. Madison. WI), or by manual alignment and visual inspection (see. e.g., Brent et al., Current Protocols in Molecular Biology, John Wiley & Sons, Inc. (Ringbou ed., 2003)). Two examples of algorithms that are suitable for determining percent sequence identity and sequence similarity are the BLAST and BLAST 2.0 algorithms, which are described in Altschul et al., Nuc. Acids Res. 25:3389-3402, 1977; and Altschul et al., J. Mol. Biol. 215:403-410, 1990, respectively. In one aspect, the disclosure provides compositions comprising multiple purified bacterial strains.

In some embodiments of the com- positions provided herein, all of the bacterial strains are human-derived bacteria. In some embodiments of the compositions provided herein, the bacterial strains are derived from more than one human donor. The bacterial strains used in the compositions provided herein generally are isolated from the microbiome of healthy individuals. In some embodiments, the compositions include strains originating from a single individual. In some embodiments, the com- positions include strains originating from multiple individuals. In some embodiments, the bacterial strains are obtained from multiple individuals, isolated and grown up indi- vidually. The bacterial compositions that are grown up individually may subsequently be combined to provide the compositions of the disclosure. It should be appreciated that the origin of the bacterial strains of the compositions provided herein is not limited to the human microbiome from a healthy individual. In some embodiments, the bacterial strains originate from a human with a microbiome in dysbiosis. In some em- bodiments, the bacterial strains originate from non-human animals or the environment (e.g., soil or surface water). In some embodiments, the combinations of bacterial strains provided herein originate from multiple sources (e.g., human and non-human animals). In some embodiments of the compositions provided herein, the composition includes one or more anaerobic bacteria. In some embodiments of the compositions provided herein, the composition includes only anaerobic bacteria. In some embodiments of the compositions provided herein, the composition includes one or more facultative anaerobic bacteria. In some embodiments of the compositions provided herein, the composition includes only facultative anaerobic bacteria. In some embodiments of the compositions provided herein, the composition includes one or more obligate anaerobic bacteria. In some embodiments of the compositions provided herein, the composition includes only obligate anaerobic bacteria. In some embodiments of the compositions provided herein, one or more of the bacterial strains does not have an antibiotic resistance gene. In some embodiments of the compositions provided herein, the bacterial strains do not have an antibiotic re- sistance gene that renders the bacterial strain resistant to vancomycin. In some embodiments of the compositions provided herein, the compositions do not include bacterial strains that are resistant to one or more antibiotics. It should be ap- preciated that it may be desirable to have a mechanism to remove the bacterial com- positions provided herein from the body after administration. One such mechanism is to remove the bacterial compositions by antibiotic treatment. Thus, in some em- bodiments, the compositions do not include bacterial strains that are resistant to one or more antibiotics. In some embodiments, the compositions do not include bacterial strains that are resistant to one or more antibiotics selected from the group consisting of penicillin, benzylpenicillin, ampicillin, sulbactam, amoxicillin, clavulanate, tazobactam, piperacillin, cefmetazole, vancomycin, imipenem, meropenem, metronidazole and clindamycin.

In some embodiments, the compositions include only bacterial strains that are susceptible to at least two antibiotics that are efficacious in humans. In some embodiments, the compositions include bacterial strains that are susceptible to at least one antibiotic that is efficacious in humans. (An "antibiotic that is efficacious in a human" as used herein is an antibiotic that has been used to successfully treat bacterial infections in a human). In some embodiments of the compositions provided herein, one or more of the bacterial strains is a spore-former. In some embodiments of the compositions provided herein, one or more of the bacterial strains is in spore form. In some embodiments of the compositions provided herein, one or more of the bacterial strains is a non-spore former. In some embodiments, the compositions described herein comprise spore forming and non-spore forming bacterial strains. In some embodiments, the compositions described herein comprise spore-forming bacterial strains. In some embodiments, the compositions described herein comprise only spore-forming bacterial strains. In some embodiments, the compositions described herein comprise only non-spore forming bacterial strains. The spore-forming bacteria can be in spore form (i.e., as spores) or in vegetative form (i.e., as vegetative cells). In spore form, bacteria are generally more resistant to environmental conditions, such as heat, acid, radiation, oxygen, chemicals, and antibiotics. In contrast, in the vegetative state or actively growing state, bacteria are more susceptible to such environmental conditions, compared to in the spore form. In general, bacterial spores are able to germinate from the spore form into a vegetative / actively growing state, under appropriate conditions. For instance, bacteria in spore format may germinate when they are introduced in the intestine. In some embodiments, at least one (e.g., 1, 2, 3, 4, 5, or more) of the bacterial strains in the composition is a spore former. In some embodiments, at least one (e.g., 1, 2, 3, 4, 5, or more) of the bacterial strains in the composition is in spore form. In some em- bodiments, at least one (e.g., 1, 2, 3, 4, 5, or more) of the bacterial strains in the com- position is a non-spore former. In some embodiments, at least one (e.g., 1, 2, 3, 4, 5, or more) of the bacterial strains in the composition is in vegetative form (as discussed above, spore forming bacteria can also be in vegetative form). In some embodiments, at least one (e.g., 1, 2, 3, 4, 5, or more) of the bacterial strains in the composition is in spore form and at least one (e.g., 1, 2, 3, 4, 5, or more) of the bacterial strains in the composition is in vegetative form. In some embodiments, at least one bacterial strain that is considered able to form spores (i.e., a spore-former) but is present in the com- position in vegetative form. In some embodiments, at least one bacterial strain that is considered able to form spores is present in the composition both in spore form and in vegetative form. CA It is envisioned that the bacterial strains of the compositions provided herein are alive and will be alive when they reach the target area (e.g., the intestines). Bacterial spores are considered to be alive in this regards. In some embodiments, bacteria that are ad- ministered as spores may germinate in the target area (e.g., the intestines). It should further be appreciated that not all of the bacteria are alive and the compositions can include a percentage (e.g., by weight) that is not alive. In addition, in some em- bodiments, the compositions include bacterial strains that are not alive when ad- ministered or at the time when the composition reaches the target area (e.g., the in- testines). It is envisioned that non-living bacteria may still be useful by providing some nutrients and metabolites for the other bacterial strains in the composition. In any of the compositions provided herein, in some embodiments, the bacterial strains are purified. In any of the compositions provided herein, in some embodiments, the bacterial strains are isolated. Any of the bacterial strains described herein may be isolated and / or purified, for example, from a source such as a culture or a microbiota sample (e.g., fecal matter). The bacterial strains used in the compositions provided herein generally are isolated from the microbiome of healthy individuals. However, bacterial strains can also be isolated from individuals that are considered not to be healthy. In some embodiments, the compositions include strains originating from multiple individuals. As used herein, the term "isolated" bacteria that have been separated from one or more undesired component, such as another bacterium or bacterial strain, one or more component of a growth medium, and / or one or more component of a sample, such as a fecal sample. In some embodiments, the bacteria are substantially isolated from a source such that other components of the source are not detected. As also used herein, the term "purified" refers to a bacterial strain or com- position comprising such that has been separated from one or more components, such as contaminants. In some embodiments, the bacterial strain is substantially free of contaminants. In some embodiments, one or more bacterial strains of a composition may be independently purified from one or more other bacteria produced and / or present in a culture or a sample containing the bacterial strain. In some embodiments, a bacterial strain is isolated or purified from a sample and then cultured under the ap- propriate conditions for bacterial replication, e.g., under anaerobic culture conditions. The bacteria that is grown under appropriate conditions for bacterial replication can subsequently be isolated / purified from the culture in which it is grown. In one aspect, the disclosure provides bacterial strains and mixtures of bacterial strains with unique biological properties. In some embodiments of the compositions provided herein, the composition induces proliferation and / or accumulation of CD8+ T-cells. In some embodiments, the bacterial strains of the compositions provided herein can induce proliferation and / or accumulation of CD8+ T-cells, because of the synergy between the bacterial strains. Thus, without being limiting to a specific mechanism, in some embodiments, the combination of the bacterial strains of the com- positions provided herein act synergistically in the induction of proliferation and / or ac- cumulation of CD8+ T-cells because the combination of the strains is particularly well- suited to generate metabolites and / or cellular signals that stimulate the induction of proliferation and / or accumulation of CD8+ T-cells. The bacterial compositions may do so, for instance through the use of nutrients in the intestinal tract (e.g., the colon or the cecum), and / or metabolic interactions that result in metabolites and / or cellular signals that stimulate the induction of proliferation and / or accumulation of CD8+ T- cells. In addition, without being limiting to a specific mechanism, in some em- bodiments, the combination of the bacterial strains of the compositions provided herein act synergistically in the induction of proliferation and / or accumulation of CD8+ T- cells because the combination of the strains is superior in engrafting specific niches in the intestinal tract (e.g., the colon or the cecum) that will result in the induction of pro- liferation and / or accumulation of CD8+ T-cells (e.g., by providing a favorable mi- croenvironment). In some embodiments, the combination of the bacterial strains of the compositions provided herein act synergistically in the induction of proliferation and / or accumulation of CD8+ T-cells because the combination of the strains is particularly well-suited to generate metabolites and / or cellular signals that stimulate the induction of proliferation and / or accumulation of CD8+ T-cells, and the combination is well suited to engraft in specific niches, that result in localization of the metabolites and / or cellular signals to a target for the induction of proliferation and / or accumulation of CD8+ T-cells

[0185] Treatment of diseases Cancer In one aspect, the disclosure includes compositions and methods for the treatment of diseases in a subject. In some embodiments of the methods provided herein, the subject has cancer. In one aspect, the cancers that can be treated according to the com- positions and methods provided herein, include without limitation, carcinoma, glioma, mesothelioma, melanoma, lymphoma, leukemia, adenocarcinoma, breast cancer, ovarian cancer, cervical cancer, glioblastoma, multiple myeloma, prostate cancer, Burkitt's lymphoma, head and neck cancer, colon cancer, colorectal cancer, non-small cell lung cancer, small cell lung cancer, cancer of the esophagus, stomach cancer, pancreatic cancer, hepatobiliary cancer, cancer of the gallbladder, cancer of the small intestine, rectal cancer, kidney cancer, bladder cancer, prostate cancer, penile cancer, urethral cancer, testicular cancer, vaginal cancer, uterine cancer, thyroid cancer, parathyroid cancer, adrenal cancer, pancreatic endocrine cancer, carcinoid cancer, bone cancer, skin cancer, retinoblastomas, Hodgkin's lymphoma, non-Hodgkin's lymphoma, CA Kaposi's sarcoma, multicentric Castleman's disease, AIDS-associated primary effusion lymphoma, neuroectodermal tumors, or rhabdomyosarcoma. In some embodiments of the methods provided herein, the cancer is prostate cancer, bladder cancer, non-small cell lung cancer, urothelial carcinoma, melanoma, or renal cell carcinoma. In some embodiments of the methods provided herein, the subject is undergoing radiation treatment. In some embodiments of the methods provided herein, the method further includes administering one or more anticancer agents. In some embodiments of the methods provided herein, the anticancer agent is a chemotherapy agent. In some embodiments of the methods provided herein, the anticancer agent is a cancer immunotherapy agent. In some embodiments of the methods provided herein, the cancer immunotherapy agent is an immune checkpoint inhibitor. In some embodiments of the methods provided herein, the immune checkpoint inhibitor is a PD-1 inhibitor, PD-L-1 inhibitor, or CTLA-4 inhibitor. In some embodiments of the methods provided herein, the immune checkpoint inhibitor is a PD-1 inhibitor. In some embodiments of the methods provided herein, the immune checkpoint inhibitor is a CTLA-4 inhibitor. In some embodiments of the methods provided herein, the cancer immunotherapy agent is a cancer vaccine that acts to increase the response of a subject's immune system to cancer cells. For example, cancer vaccines include cancer antigen(s) that act to induce or stimulate an immune response against cells bearing the cancer antigen(s). The immune response induced or stimulated can include an antibody (humoral) immune response and / or a T-cell (cell-mediated) immune response. CD8+ T-cells can differentiate into cytotoxic T-cells that kill target cells bearing the antigen recognized by CD8+ T-cells. Induction of CD8+ T-cells can, therefore, enhance the immune response to cancer antigens provided in a cancer vaccine. In some embodiments of the methods provided herein, the cancer immunotherapy agent is a CAR-T therapeutic. CAR-T cells include T-cells taken from a patient that are genetically engineered to produce chimeric antigen receptors (CARs) on their surface. The CARs are engineered to recognize a specific antigen on cancer cells. After the CAR-T cells are infused into the patient, they recognize and kill cancer cells that express the specific antigen on their surfaces. Induction of CD8+ T-cells is useful to provide cells for conversion into CAR-T cells. In some embodiments of the methods provided herein, the method further includes administering one or more cytokines. In some embodiments of the methods provided herein the cytokine is IL-2, IL-15, or IL-21. In some embodiments of the methods provided herein, the method further includes administering one or more costimulatory agents. In some embodiments of the methods provided herein the costimulatory agent is a CD-28, OX-40, 4-1BB, or CD40 antibody. In some embodiments of the methods provided herein, the method further includes ad- ministering one or more vaccines. In some embodiments of the methods provided herein, the vaccine is a dendritic cell vaccine. In some embodiments of the methods provided herein, the method further includes ad- ministering adoptive cell transfer therapy.
