| ABSTRACT Mastitis caused by Mycoplasma spp., regardless of species, are considered highly contagious pathogens and, usually was not responsive to antimicrobial therapy. Five dairy herds, comprising 489 animals and 1,956 mammary glands, were used in this study. Milk samples were obtained from bulk tanks and subjected to polymerase chain reaction (PCR) for the identification of Mollicutes, Mycoplasma spp., and Mycoplasma bovis. Moreover, individual samples from cases of clinical and subclinical mastitis in quarters of the dairy herds’ animals that yielded a positive PCR upon bulk tank analysis were subjected to molecular analysis. Only one bulk tank was positive for class Mollicutes by PCR. All positive samples classified as mastitis teats had their DNA... |

| ABSTRACT Milk samples from 257 goats and 513 half udders of 10 dairy goat farms were analyzed by microbiological culture, to evaluate the sanitary management, and epidemiological questionnaire results. Multivariate analysis of risk factors for subclinical mastitis in goats, with the adjusted Odds Ratio for subclinical mastitis was performed. The prevalence of subclinical mastitis in goats by microbiological culture was 43.6%, and clinical mastitis was 5.84%. From 178 positive teats by microbiological culture, the most prevalent pathogens were coagulase-negative staphylococci - CNS (70%), S. aureus (13.5%), S. intermedius (7.9%), and Enterobacteriaceae (4%). The risk factors analysis revealed significant association between the disease and the flock size... |
