Abstract

Disclosed herein are therapeutic compositions containing non-pathogenic, germination-competent bacterial spores, for the prevention, control, and treatment of gastrointestinal diseases, disorders and conditions and for general nutritional health.

First claim

1 .- 99 . (canceled)

100 . A composition for treating or reducing a severity of at least one symptom of a gastrointestinal disease, disorder or condition associated with a dysbiosis in a subject, the composition comprising a purified population of at least one species of germinable bacterial spores in an amount effective to populate a gastrointestinal tract in the subject, wherein
the composition is derived from fecal material subjected to ethanol treatment or heat treatment; and the composition is substantially depleted of a residual habitat product of the fecal material; and the at least one species of germinable bacterial spores is not detectable in the fecal material before the ethanol treatment or heat treatment.

101 . The composition of claim 100 , wherein the at least one species of germinable bacterial spores is selected from Table 5.

102 . A composition for treating or reducing a severity of at least one symptom of a gastrointestinal disease, disorder or condition associated with a dysbiosis in a subject, the composition comprising a purified population of at least one species of germinable bacterial spores selected from Table 5 in an amount effective to populate a gastrointestinal tract in the subject.

103 . The composition of claim 100 , wherein the at least one species of germinable bacterial spores is selected from the group consisting of Bacillus licheniformis, Bacillus pumilus, Brevibacillus parabrevis, Clostridium hylemonae, Clostridium methylpentosum , and Clostridium sp. YIT 12069.

104 . The composition of claim 100 , wherein the at least one species of germinable bacterial spores is selected from the group consisting of Acetivibrio ethanolgignens, Anaerofustis stercorihominis, Bacillus anthracis, Bacillus horti, Bacillus nealsonii, Bacillus sp. BT1B_CT2, Bacillus thuringiensis, Bacteroides galacturonicus, Bacteroides pectinophilus, Brachyspira pilosicoli, Clostridium aldenense, Clostridium beijerinckii, Clostridium carnis, Clostridium celatum, Clostridium favososporum, Clostridium irregulare, Clostridium sp. L2-50, Clostridium sp. MT4 E, Clostridium sp. NML 04A032, Clostridium sp. SS2/1, Clostridium stercorarium, Clostridium xylanolyticum, Coprococcus sp. ART55/1 , Deferribacteres sp. oral clone JV006 , Desulfitobacterium frappieri, Eubacterium callanderi, Eubacterium siraeum, Exiguobacterium acetylicum, Gemmiger formicilis, Lachnospira multipara, Lachnospira pectinoschiza, Roseburia faecalis , and Ruminococcus albus.

105 . The composition of claim 100 , wherein the at least one species of germinable bacterial spores is Blautia wexlerae or Clostridium sp. D5.

106 . The composition of claim 100 , wherein the composition comprises an amount of bacteria effective to augment growth in the subject's gastrointestinal tract of at least one bacteria not detectable in the composition or to modulate microbiota diversity after administration of the composition compared to the microbiota diversity present in the subject's gastrointestinal tract prior to administration of the composition.

107 . The composition of claim 100 , wherein the subject is a human.

108 . The composition of claim 100 , wherein the gastrointestinal disease, disorder or condition is selected from the group consisting of Clostridium difficile -induced diarrhea, irritable bowel syndrome (IBS), infection or colonization with a pathogen or pathobiont including a drug resistant pathogen or pathobiont, colitis, a metabolic disorder, and Crohn's disease.

109 . The composition of claim 100 , wherein the gastrointestinal disease, disorder or condition is Clostridium difficile -induced diarrhea.

110 . The composition of claim 100 , wherein the composition comprises at least 1×10 4 colony forming units of the germinable bacterial spores per dose of the composition.

111 . The composition of claim 100 , wherein the fecal material is obtained from a validated mammalian donor subject not having a detectable level of a pathogen or a pathobiont prior to production of the fecal material.

112 . The composition of claim 100 , wherein the fecal material is obtained from a validated mammalian donor subject not having a detectable level of a pathogen or a pathobiont prior to production of the fecal material and the pathogen or a pathobiont is selected from the group consisting of blood-borne pathogens (HIV, HTLV, HCV, HBV, CMV, HAV and Treponema pallidum ) and fecal bacterial pathogens ( Salmonella, Shigella, Yersinia, Campylobacter, E. coli 0157), ova and parasites, and other infectious agents ( Giardia, Cryptosporidium Cyclospora, Isospora ).

113 . The composition of claim 100 , wherein the ethanol treatment comprises
a. forming a 10% w/v suspension of human fecal material; b. mixing the suspension with absolute ethanol in a 1:1 ratio; c. incubating the suspension of (b); d. collecting the bacterial spores in the suspension; e. adding glycerol to the bacterial spores of (d); and f. storing the composition at −80 degrees Celsius.

114 . The composition of claim 100 , wherein the heat treatment comprises
a. forming a 10% w/v suspension of human fecal material in PBS; b. incubating the suspension of (a) at 80 degrees Celsius for 30 minutes, thereby forming a heat treated suspension; c. adding glycerol to the heat treated suspension; and d. storing the composition at −80 degrees Celsius.

115 . The composition of claim 100 , wherein the residual habitat product is an abiotic material, a human or animal cell, a virus, a fungus, or a mycoplasma.

116 . The composition of claim 100 , wherein the at least one species of germinable bacterial spores is not detectable in the fecal material before treatment by genomic and/or microbiological assay methods.

117 . The composition of claim 100 , wherein the at least one species of germinable bacterial spores is not detectable in the fecal material before treatment by qPCR.

118 . The composition of claim 100 , comprising a delayed release capsule.

119 . The composition of claim 100 , formulated for oral administration.

120 . The composition of claim 100 , further comprising an antibiotic.
