1 .- 30 . (canceled)
31 . A pharmaceutical composition that comprises an amount of a live bacteria strain of species Enterococcus faecium and a pharmaceutically effective excipient, diluent, or carrier; wherein said Enterococcus faecium bacteria strain comprises a polynucleotide sequence that is a 16 s rRNA gene sequence with at least 95% sequence identity to SEQ ID NO:2, as determined by a Smith-Waterman homology search algorithm, using an affine gap search with a gap open penalty of 12, a gap extension penalty of 2, and a BLOSUM matrix of 62.
32 . The pharmaceutical composition of claim 31 , wherein said amount of said Enterococcus faecium bacteria strain is effective to reduce a degree of infiltration of inflammatory cells in a retinal tissue when administered to a subject, relative to a degree of infiltration of said inflammatory cells in said retinal tissue of said subject prior to said administering.
33 . The pharmaceutical composition of claim 31 , wherein said Enterococcus faecium bacteria strain is positive for fermentation of mannose, as determined by a Rapid ID 32A analysis.
34 . The pharmaceutical composition of claim 31 , wherein said Enterococcus faecium bacteria strain is positive for serine arylamidase, as determined by said Rapid ID 32A analysis.
35 . The pharmaceutical composition of claim 31 , wherein said Enterococcus faecium bacteria strain is intermediate for N-acetyl-β-glucosaminidase by said Rapid ID 32A analysis.
36 . The pharmaceutical composition of claim 31 , wherein said pharmaceutical composition is lyophilized.
37 . The pharmaceutical composition of claim 31 , wherein said Enterococcus faecium bacteria strain is the sole bacteria strain present in said pharmaceutical composition.
38 . The pharmaceutical composition of claim 31 , formulated for oral delivery.
39 . The pharmaceutical composition of claim 31 , formulated for rectal delivery.
40 . The pharmaceutical composition of claim 31 , formulated as an injectable formulation.
41 . The pharmaceutical composition of claim 31 , in the form of a tablet, a capsule, or a powder.
42 . The pharmaceutical composition of claim 31 , wherein at least 50% of said Enterococcus faecium bacteria strain as measured by an amount of colony forming units (CFU), remains viable after about 1 year of storage when said pharmaceutical composition is stored in a closed container at 25° C. at 95% relative humidity.
43 . The pharmaceutical composition of claim 31 , wherein said pharmaceutical composition is encapsulated.
44 . The pharmaceutical composition of claim 31 , wherein said pharmaceutical composition is an enteric formulation.
45 . The pharmaceutical composition of claim 44 , wherein said enteric formulation comprises an enteric coating.
46 . The pharmaceutical composition of claim 31 , further comprising a prebiotic compound selected from the group consisting of: a fructo-oligosaccharide, a short-chain fructooligosaccharide, inulin, an isomalt-oligosaccharide, a galacto-oligosaccharide, a pectin, a xylo-oligosaccharide a chitosan-oligosaccharide, a beta-glucan, an arable gum modified starch, a polydextrose, a D-tagatose, an acacia fiber, carob, an oat, and a citrus fiber.
