Outbreak of clinical mastitis caused by Corynebacterium spp. and Streptococcus dysgalactiae in goats in Salta, Argentina
Abstract
Intramammary infections are a serious problem for goat’s milk production worldwide. Staphylococcus spp. are the most prevalent pathogens responsible for intramammary infection in small ruminants; however, there is only little information about goat mastitis in Argentina. The objective of this communication was to describe an outbreak of clinical mastitis affecting 12 of 24 lactating goats. Corynebacterium spp. and Streptococcus dysgalactiae were isolated in pure culture from all milk samples. All the clinical isolates were identified by biochemical tests and subjected to antibiotic susceptibility tests.
Keywords: small ruminants, mastitis, intramammary infection.
