Origin of intestinal beta-glucuronidase in germfree, monocontaminated and conventional rats. 1977

T O Rod, and T Midtvedt

The intestinal beta-glucoronidase was studied in germfree, monocontaminated and conventional rats. The greater part of the beta-glucuronidase of the caecum and the large intestine of the contaminated animals was of bacterial origin. No bacterial beta-glucuronidase was found in the small intestine. Monocontamination with Escherichia coli gave activities corresponding to those of the conventional rats, whereas content from the caecum and the large intestine of the rats monocontaminated with Streptococcus pyogenes showed an activity approximately 10 per cent of that of the conventional rats.

D002432	Cecum	The blind sac or outpouching area of the LARGE INTESTINE that is below the entrance of the SMALL INTESTINE. It has a worm-like extension, the vermiform APPENDIX.	Cecums
D004926	Escherichia coli	A species of gram-negative, facultatively anaerobic, rod-shaped bacteria (GRAM-NEGATIVE FACULTATIVELY ANAEROBIC RODS) commonly found in the lower part of the intestine of warm-blooded animals. It is usually nonpathogenic, but some strains are known to produce DIARRHEA and pyogenic infections. Pathogenic strains (virotypes) are classified by their specific pathogenic mechanisms such as toxins (ENTEROTOXIGENIC ESCHERICHIA COLI), etc.	Alkalescens-Dispar Group,Bacillus coli,Bacterium coli,Bacterium coli commune,Diffusely Adherent Escherichia coli,E coli,EAggEC,Enteroaggregative Escherichia coli,Enterococcus coli,Diffusely Adherent E. coli,Enteroaggregative E. coli,Enteroinvasive E. coli,Enteroinvasive Escherichia coli
