We examined the fecal microflora of 1-3-month-oId infants during treatment with phenoxymethyl penicilIin, amoxycilIin, pivampicilIin, cefaclor, cefadroxil, Ioracarbef, erythromycin or cotrimoxazole. Escherichia coli increased during treatment with penicilIins or cephalosporins, but was not affected by erythromycin or cotrimoxazole. Other enterobacteria were acquired or increased during treatment with all agents except cotrimoxazole. Enterococci persisted or increased during phenoxymethyl penicillin, cephalosporin or cotrimoxazole treatment, whereas erythromycin and the other penicillins suppressed them. Bacteroides, bifidobacteria and Iactobacilli were suppressed to undetectable Ievels in most infants during treatment with all agents, except phenoxymethyl penicillin and loracarbef.
