| Research Abstract |
Our results indicate that there are quantitative and qualitative differences in the responsiveness of Kupffer cells during Salmonella typhimurium infection depending upon the presence or absence of intestinal bacterial flora.
No direct relationship was not observed between concentration of O_2 production in Ex vivo, intensity of granulomatous lesions formed in the liver and viable bacterial counts recovered from liver and spleen during S. typhimurium infection. These facts are believed to be invaluable footholds in elucidating mechanism of pathogenesis of facultative intracellular bacterial infection.
