Abstract
Summary
Tissue O2 and CO2 tensions were estimated with subcutaneous gas pockets in germfree rats, conventional rats, and germfree rats that were newly-infected with a normal rat intestional bacterium, Clostridium difficile. Differences between groups were not large. Newly-infected rats appeared to have low local blood flow the first day and an additional unexplained low pCO2 the second day after infection. Germfree female rats had lower pCO2 than germfree or conventional males and conventional females.
