Prevalence and antimicrobial susceptibility of udder pathogens isolated from dairy cows in Slovakia

Abstract

Abstract The data presented in this research communication represent the first comprehensive report on the prevalence of udder pathogens and their resistance in Slovak dairy cattle breeds. A total of 633 milk samples from 42 herds were tested. The most frequently isolated pathogens were coagulase negative staphylococci CNS or non-aureus staphylococci (NAS) followed by Escherichia (E.) coli, Staphylococcus (S.) aureus, Streptococcus (Str.) uberis and Streptococcus (Str.) agalactiae . Generally, isolated pathogens showed common resistance to aminoglycosides (streptomycin, neomycin), which are the most commonly used antibiotics to treat mastitis in Slovakia.
