Antimicrobials are commonly used to treat diseases in dairy cows and in calves. In Argentina information about veterinary antimicrobial usage at herd level is still limited. The purpose of this study was to quantify antimicrobial usage at herd level of most used drugs to treat lactating cows (LC) and preweaned calves (PWC). Prevalence of diseases and(More)
Few studies have described the relationship between genotypic and phenotypic methods for detecting penicillin resistance in Staphylococcus aureus isolated from bovine intramammary infection (IMI). Six phenotypic methods for penicillinase detection were compared with a genotypic method testing the presence of the β-lactamase gene blaZ in Staph. aureus (n =(More)
Different species of Mycoplasma can affect bovine cattle, causing several diseases. PCR sequencing and further analysis of the 16S-23S rRNA ITS region have shown a significant interspecies variability among Mollicutes. Sixteen suspected isolates of Mycoplasma spp. obtained from milk samples from dairy herds were amplified (16S-23S rRNA ITS region). Fourteen(More)
