COMPOSITIONS COMPRISING BACTERIAL STRAINS
The invention provides pharmaceutical compositions comprising bacteria and the use of such compositions in the treatment of disease.
1 .- 44 . (canceled)
45 . A composition comprising a lyophilized bacterial strain of the genus Eubacterium , wherein the bacterial stain comprises a 16S rRNA gene sequence having at least 95% sequence identity to the sequence of SEQ ID NO: 8.
46 . The composition of claim 45 , wherein the composition comprises at least about 1×10 3 colony forming units (CFU) of the bacteria strain.
47 . The composition of claim 45 , wherein the composition comprises from about 1×10 3 to about 1×10 11 colony forming units per gram (CFU/g), with respect to a total weight of the composition.
48 . The composition of claim 45 , wherein the bacterial strain is viable.
49 . The composition of claim 45 , wherein the composition comprises fewer than 40 different bacterial strains.
50 . The composition of claim 45 , wherein the composition is formulated for oral or rectal administration.
51 . The composition of claim 45 , wherein the composition is formulated as a tablet, capsule, or powder.
52 . The composition of claim 45 , further comprising a prebiotic compound.
53 . The composition of claim 45 , further comprising a preservative, an antioxidant, or a stabilizer.
54 . The composition of claim 45 , further comprising a pharmaceutically acceptable excipient, diluent, or carrier.
55 . The composition of claim 45 , wherein the at least 95% sequence identity is determined by a Smith-Waterman homology search algorithm using an affine gap search with a gap open penalty of 12 and a gap extension penalty of 2.
56 . The composition of claim 45 , wherein the bacterial strain comprises a 16S rRNA gene sequence having at least 98% sequence identity to the sequence of SEQ ID NO: 8.
57 . The composition of claim 45 , wherein the bacterial strain comprises a 16S rRNA gene sequence that is the sequence of SEQ ID NO: 8.
58 . The composition of claim 45 , wherein the bacterial strain is of the species Eubacterium callanderi or Eubacterium limosum.
59 . The composition of claim 58 , wherein the bacterial strain is of the species Eubacterium callanderi.
60 . The composition of claim 59 , wherein the bacterial strain is a bacterial strain deposited under accession number NCIB 43455.
61 . A method of treating a central nervous system disorder or condition in a subject in need thereof, the method comprising administering to the subject a composition comprising a bacterial strain of the genus Eubacterium , wherein the bacterial stain comprises a 16S rRNA gene sequence having at least 95% sequence identity to the sequence of SEQ ID NO: 8, and wherein the administering is sufficient to treat the central nervous system disorder or condition in the subject.
62 . The method of claim 61 , wherein the central nervous system disorder or condition comprises a neurodevelopmental disorder or a neuropsychiatric condition.
63 . The method of claim 61 , wherein the central nervous system disorder or condition comprises autism spectrum disorders (ASDs), child developmental disorder, obsessive compulsive disorder (OCD), major depressive disorder (MDD), depression, seasonal affective disorder, anxiety disorders, chronic fatigue syndrome (myalgic encephalomyelitis), stress disorder, post-traumatic stress disorder, schizophrenia spectrum disorders, schizophrenia, bipolar disorder, psychosis, mood disorder, dementia, Alzheimer's disease, Parkinson's disease, chronic pain, motor neuron disease, Huntington's disease, Guillain Barre syndrome, or meningitis.
64 . The method of claim 61 , wherein the bacterial strain comprises a 16S rRNA gene sequence having at least 98% sequence identity to the sequence of SEQ ID NO: 8.
