Sumario:No urobilinogens are present in the feces or urine of germfree rats. After contamination of germfree animals with feces from conventional animals the exgermfree rats produced urobilins to the same extent as conventional animals on the same diet. The negative urobilin test turned positive in germfree animals infected with a single Clostridium-like microorganism isolated from the intestinal contents of rats with urobilins in the feces. The output increased in these monoinfected animals after superinfection with a strain of E. coli but never reached the values of conventional animals.
