摘　　要：Microbial populations in the gastrointestinal tract contribute to host health and nutrition.Although gut microbial ecology is well studied in livestock and domestic animals,little is known of the endogenous populations inhab­iting primates or carnivora.We characterized microbial populations in fecal cultures from gorillas(Gorilla go­rilla gorilla),common chimpanzees(Pan troglodytes),Hamadryas baboons(Papio hamadryas)and binturongs(Arctictis binturong)to compare the microbiomes associated with different gastrointestinal morphologies and different omnivorous feeding strategies.Each species was fed a distinct standardized diet for 2 weeks prior to fecal collection.All diets were formulated to reflect the species’feeding strategies in situ.Fresh fecal samples were pooled within species and used to inoculate in vitro batch cultures.Acetate,propionate,butyrate and val­erate were measured after 24 h of incubation.Eubacterial DNA was extracted from individual fecal samples,pooled,and the cpn60 gene region was amplified and then sequenced to identify the major eubacterial constit­uents associated with each host species.Short chain fatty acids(P<0.001)and methane(P<0.001)were sig­nificantly different across species.Eubacterial profiles were consistent with fermentation data and suggest an in­crease in diversity with dietary fiber.
