ABSTRACT
With the objective of examining the frequency of bacterial agents involved in the clinical and subclinical inflammatory processes of the mammary glands of buffalos and to study the sensitivity profile of the isolated agents 128 lactating buffalos (a total of 512 mammary quarters) were examined. The “California Mastitis Test” was the method used for the diagnosis of frequency of subclinical cases and physical examination of the udder and a screened mug test for identification of the clinical cases. Samples of milk were collected from the quarters that showed a reaction to CMT (scores 1+, 2+, 3+) and from those with clinical mastitis. All samples were previously microbiologically tested for the identification of the agents involved together with the sensitivity tests and antimicrobials. The results indicated that the bacteria isolated and associated in the clinical and subclinical cases of the disease were mainly Staphylococcus coagulase negative.The in vitrosensitivity tests showed greater efficacy for gentamicin antibiotics (97.98%), florfenicol (93.94%) and enrophloxine (90.90%). Gentamicin showed 100% efficacy in the treatment of the clinical cases and was considered the best treatment for the control of the disease in the herd in this study.
