Candida albicans gastrointestinal colonization and invasion in the mouse: effect of antibacterial dosing, antifungal therapy and immunosuppression.


Infant mice infected with Candida albicans by the oral-intragastric route became colonized in the gut and were persistently colonized into adulthood. Faecal levels of Candida were correlated with total gastrointestinal Candida and provided a useful means of detecting yeast overgrowth or elimination. Antibacterial agents promoting Candida overgrowth when given by the oral or parenteral route included ceftriaxone, augmentin and cefoperazone. Ceftizoxime had less effect. Ceftazidime and latamoxef produced raised levels only by the oral route. Gentamicin, vancomycin and metronidazole did not affect the Candida levels. Dosing with some antibacterials promoted an increase in gastrointestinal Candida and invasion to a greater extent than immunosuppression. Antifungal therapy to reduce gastrointestinal colonization was investigated using amphotericin B, nystatin, ketoconazole, intraconazole and fluconazole. Fluconazole was most effective at reducing faecal Candida.
