Gianneechini RE Concha C Franklin A Antimicrobial susceptibility of udder pathogens isolated from dairy herds in the west littoral region of Uruguay. Acta vet. scand. 2002 43 31-41. - A total of 522 strains belonging to streptococci enterococci and staphylococci isolated from sub-clinical and clinical cases of bovine mastitis from the west littoral region of Uruguay were analysed for their susceptibility to several antimicrobial agents. The susceptibility patterns were studied by agar disk diffusion methods ADDM and broth micro-dilution to determine the minimum inhibitory concentration MIC . The concentration that inhibits 90 MIC90 of the analysed strains reported in micrograms per millilitre for Staphylococcus aureus were 8 8 0.5 4 1 0.5 64 0.25 0.5 1 and 1 to penicillin ampicillin oxacillin cephalotin gentamicin erythromycin oxitetracycline enrofloxacin trimethoprim sulfamethoxazole neomycin and clindamycin respectively. Coagulase-negative staphylococci CNS had different values for penicillin 4 and ampicillin 2 while the other antimicrobial agents had the same MIC90 values as reported for 5. aureus. The MIC90 values for streptococci were 0.12 0.25 4 16 0.25 0.5 0.25 for penicillin ampicillin cephalotin gentamicin erythromycin oxytetracycline and trimethoprim-sulfamethoxazole whereas MIC90 for enterococci were 4 4 4 0.5 2 8 for penicillin ampicillin gentamicin erythromycin oxytetracycline and trimethoprim-sulfamethoxazole respectively. Of 336 strains of 5. aureus 160 47.6 were resistant to penicillin. For 41 CNS strains 10 27 presented
