A total of 42 Streptococci isolated from 148 milk samples of normal, sub acute and acute bovine mastitis cases. Overall, 35% of the strains tested were Streptococcus dysgalactiae,(More)
The purpose of this study was to describe antimicrobial susceptibility of environmental mastitis pathogens isolated from dairy herds of Chahar Mahal province in west central Iran. Out of the 620 milk samples collected from the four districts, 180 were CMT (California mastitis test) positive that cultured and yield, 7 (3.88%) coagulase negative Staphylococci(More)
