Parasitic infections in germfree animals.
The association of vertebrate hosts with the indigenous microbiota and its effect on the response to infections has long been a subject of scientific curiosity. From the first theory supported by Louis Pasteur that life would be impossible in the absence of associated microorganisms to the development of germfree mammals for research, a lot was learned about how the normal microbiota influences...
متن کاملBilirubin and Urobilins in Germfree, Ex-germfree, and Conventional Rats
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 conte...

Genetically closely related conventional animals on the same sterilized diet did not present a single case of stone formation. The tendency to calculus formation disappeared when germfree animals were contaminated with the intestinal flora from conventional rats. The calcul...

متن کاملShwartzman reaction in germfree rabbits.

From the results it was concluded that the presence of natural antibody to endotoxin is not a prerequisite of the production of the local Shwartzman reaction by bacterial endotoxin.
