Abstract
Some tests of exocrine pancreatic function are based on the estimation of intestinal chymotryptic activity by using specific substrates such asN-benzoyl-l-tyrosyl-PABA (BT-P). In this study the action of a number of bacteria isolated from human or monkey intestines on BT-P was investigated. The monkeys studied had an intestinal flora closely resembling that of man. Except forBacteroides, Proteus vulgaris No. 73,Proteus morgani No. 202, andPseudomonas aeruginosa No. 76, significant splitting of BT-P did not take place when the common enteric microorganisms were tested. It was concluded that with the possible exception of bacterial overgrowth of the small bowel, microbial chymotryptic activity is not of importance.Keywords
