The influence of Bacillus piliformis (Tyzzer) infections on the reliability of pharmacokinetic experiments in mice.
The half-lives of warfarin and trimethoprim were significantly longer in mice acutely infected with Bacillus piloformis and in mice which ad clinically recovered from previous experimental infection with the organism. The volume of distribution of trimethoprim but not of warfarin was significantly greater in infected mice than in controls. Body clearances of warfarin was significantly reduced in both disease states. For trimethoprim this parameter was only reduced in the acute state of the disease. The importance of careful control of Tyzzer's disease in laboratory animals for use in pharmacological research is stressed.
