Vntimicrobial Susceptibility of Coagulase-Negative Staphylococci Isolated from Bovine Mastitis in Argentina

摘要

A total of 123 isolates of coagulase-negative staphylo- cocci isolated from bovine clinical and subclinical masti- tis in Argentina from March 1998 to March 2000 was investigated for in vitro susceptibility to several antimi- crobial agents. Minimum inhibitory concentrations that inhibit 90/100 of the isolates tested (reported in micro- grams per milliliter) were: 4.40, 0.38, 4.00, 0.75, 0.75 3.60, and 2.00 for penicillin, oxacillin, cephalothin, gen- tamicin, erythromycin, clindamycin, and ampicillin- sulbactam, respectively.
