A method for treating an individual suffering from one of bladder cancer and colorectal cancer employs a CRISPR system to selectively kill or reduce the numbers of pathogenic bacteria within the individual and the individual is then administered an immune checkpoint inhibitor. In particular embodiments, the pathogenic bacteria is one of E. coli, Pseudomonas aeruginosa and Klebsiella bacteria, and the checkpoint inhibitor is selected from the group consisting of nivolumab, pembrolizumab, pidilizumab, AMP-224, AMP-514, STI-A1110, TSR-042, RG-7446, BMS-936559, MEDI-4736, MSB-0020718C, AUR-012 and STI-A1010. Further embodiments include enhancing the growth of a second bacteria in the individual, such bacteria including Akkermansia, Bacteroides, Bifidobacterium, Clostridium, Enterococcus, Fusobacterium, Lactobacillus, Propionibacterium, Ruminococcus, Veillonella, Prevotella, Escherichia and Streptococcus. Still other embodiments include increasing the levels of Roseburia and / or Faecalibacterium prausnitzii, in the individual's gut microbiome.

Provided herein are, inter alia, microbial compositions and methods of using the same. The microbial compositions provided include, inter alia, therapeutically effective amounts of Lactobacillus johnsonii, Faecalibacterium prausnitzii, Akkermansia muciniphila, Myxococcus xanthus and Pediococcus pentosaceus and are particularly useful for methods of treating and preventing inflammatory diseases.

A person's intestinal (gut), oral or skin microbiota is modified using specific combinations of pre-biotics, pro-biotics and / or anti-biotics to establish a defined microbiota that can treat and / or reduce the likelihood that individuals will experience various diseases, including cancer. The employment of various bacteria, whether in particular combinations or after being modified using CRISPR-type systems, leads to improved outcomes when checkpoint inhibitors are used to treat various forms of cancer. One embodiment is directed to a method for reducing the likelihood of developing cancer by providing in the gut of an individual a population of beneficial bacteria selected from the group consisting of Lactobacillus species. The level of Roseburia and Faecalibacterium prausnitzii, and / or Akkermansia muciniphila bacteria are increased in the individual's gut microbiome such that when an individual is administered an immune checkpoint inhibitor, its function is enhanced due to the presence of the bacterial population.

A method for increasing gastric tract acid (GTA) production in a mammalian subject. The method comprises administering a therapeutically-effective amount of a composition comprising at least one liveor attenuated culture of a microbial species selected from the genus Blautia, species Faecalibacterium prausnitzii, genus Bacteroides, family Ruminococcaceae, family Lachnospiraceae, genus Coprococcus, genus Roseburia, genus Oscillospira, species Ruminococcus bromii, genus Ruminococcus, family Costridiaceae, species Dorea formicigenerans, species Bacteroides uniformis, genus Dorea, genus Streptococcus, order Clostridiales, genus Anaerostipes, genus Dialister, species Bifidobacterium adolescentis, family Coriobacteriaceae, genus Faecalibacterium, genus Sutterella, species Bacteroides ovatus, genus Parabacteroides, genus Ruminococcus, species Bacteroides faecis, species Eubacterium biforme, genus Phascolartobacterium, and family Enterobacteriaceae; or a prebiotic composition which increasesgrowth and / or viability of said microbial species in the gut. Administering the composition increases the synthesis of at least one GTA dicarboxylic fatty acid metabolite in said subject. Also described are method for determining gastrointestinal inflammation status and kits for detecting and treating a gastric tract acid (GTA) insufficiency.

A method for reducing the likelihood of developing liver cancer in an individual diagnosed with non-alcoholic fatty liver disease involves providing in the gut of an individual a population of beneficial bacteria selected from the group consisting of Lactobacillus species, and administering fiber to the individual to maintain a therapeutically effective amount of the beneficial bacteria in the gut of the individual. In certain embodiments, monoacylglycerolacyltransferase-3 (MGAT3) synthesis is inhibited to lower triacylglycerol (TAG) production, while in others, expression of diacylglycerolacyltransferase-2 (DGAT-2) is inhibited. The beneficial bacteria are preferably modified to produce increased amounts of butyrate and may also be encapsulated in a frangible enclosure. Levels of Roseburia are preferably increased while the levels of Akkermansia spp. in the individual's gut microbiome are reduced. In other embodiments, a therapeutically effective amount of a bacterial formulation comprising Faecalibacterium prausnitzii is administered, or a composition comprising modified L. reuteri bacteria having the ability to survive conditions in the duodenum or jejunum of the individual's small intestine. Other embodiments include the administration of a bacterial formulation comprising at least one of Coprococcus, Veillonella, Roseburia, Bifidobacterium, Faecalibacterium prausnitzii and Prevotella.
