Isolation of Arcobacter spp from the milk of dairy cows in Brazil Isolamento de Arcobacter spp do leite de vacas leiteiras no Brasil
Bacteriologic examinations were performed on 188 milk samples collected from cows from 11 farms for diagnosis of mastitis in three cities of Rio Grande do Sul, Brazil. Among the common causes of mastitis, the most frequent isolates were Staphylococcus aureus, followed by Corynebacterium sp, Streptoc...
