A note on lactobacilli and beta-glucuronidase activity in the intestinal contents of mice

J Appl Bacteriol. 1993 Jun;74(6):649-51. doi: 10.1111/j.1365-2672.1993.tb05198.x.


A comparison was made of caecal beta-glucuronidase activity in the caecal contents of mice with or without lactobacilli as members of the normal microflora. Male mice that did not have lactobacilli as intestinal inhabitants had approximately 52% more caecal beta-glucuronidase activity than their female counterparts. Colonization of male mice by lactobacilli reduced the beta-glucuronidase activity to that of female mice.
