Abstrakt: ABSTRACTThis work describes an outbreak of clinical mastitis affecting 13 of 58 lactating ewes due to Streptococcus equisubsp. zooepidemicus. S. equisubsp. zooepidemicuswas isolated in pure culture from all milk samples. All the clinical isolates had identical biochemical profiles and antimicrobial susceptibility patterns and also exhibited indistinguishable macrorestriction patterns by pulsed-field gel electrophoresis, indicating that all cases of mastitis were produced by a single strain.
