| Research Abstract |
Tannin-protein complex degrading enterobacteria (T-PCDE) were isolated from herbivorous primates in zoological parks in Japan. The bacteria were composed of four Streptococcus gallolyticus strains ; from Abisinian colobus, purple faced lunger, gorilla and chimpanzee, five Klebsiella pneumoniae strains ; from gorilla.S.gallolyticus, previously reported as T-PCDE isolated from Australian marsupial herbivores was also revealed to be an enterobacterium of browsing primates. Several strains of K.pneumoniae, which were isolated from leaf mold have been reported to be tannin producing soil bacteria in previous studies. However this species first appeared to be a T-PCDE in animals in the present study. The ratio of T-PCD S.gallolyticus to fecal streptococci from each primate species ranged from 0.4 to 14.2% and the ratio of T-PCD K.pneumoniae to gram-negative enterobacteria from the gorilla was 17.3%. These finding indicated that the leaf eating primates like colobuses and gorillas are able to solve the problem of tannin toxicity by symbiosis with T-PCDE similar to other herbivores reported previously. The bacteria reported in this stady will be able to being used for utilization of tannin rich feed in farming by implanting them into animal digestive tract.
