Twenty cows and three heifers with summer mastitis-like signs were included in the study . Forty aerobic and 38 anaerobic bacterial isolates representing 23 different species were isolated from udder secretions, the mean number of species being 3 .4/sample. Pathogens most often were recovered in quantities exceeding 10'' CFU/ml. Growth of pathogenic bacteria in the blood was found in only one case . Most cases occurred in housed animals and had often been preceded by teat injury. No anaerobic growth was found in milk samples of a control group consisting of 29 cows with ordinary acute mastitis . Values of indicators of inflammation in milk (NAGase and plasmin activity) were high, mean values being 914 .1 and 1 .3 units . The animals with aerobic/anaerobic mastitis were treated using various antimicrobial agents. All but three quarters were lost to milk production . Two animals with complete recovery were given a combination of penicillin G and tinidazole .
