RESUMO Foram estudadas 135 vacas mestiças, provenientes de 10 rebanhos leiteiros no estado do Acre. O objetivo foi identificar espécies Staphylococcus isoladas dos quartos mamários com mastite e, posteriormente, avaliar a capacidade produção biofilme pela espécie chromogenes. A caracterização isolados presentes nas amostras encontradas, correspondentes sp., realizada utilizando-se técnica MALDI TOF MS (Matrix Associated Laser Desorption-Ionization - Time of Flight Mass Spectrometry)....
Staphylococcus bacteria are often associated with subclinical bovine mastitis. This study aimed to identify multiresistant spp. mastitis and the risk factors. Twenty-three dairy farms a history of decrease in milk production, located lower Acre region, Brazil, were selected. An epidemiological questionnaire was provided all farms. All animals examined using California Mastitis Test (CMT) their samples collected for bacterial culture. After isolation identification, disk diffusion...
Staphylococcus species are important pathogens associated to mastitis in lactating cows. Among coagulase‐negative staphylococci, chromogenes is one of the most prevalent. However, virulence and antimicrobial resistance studies have been done aureus isolates. Therefore, aim present study was determine susceptibility profile biofilm producing S. isolates recovered from cows with Northern region Brazil. Of hundred thirty‐five crossbred ten dairy farms milk production decline, sixty‐seven were...
ABSTRACT This study aimed to identify the Staphylococcus species responsible for bovine mastitis in dairy herds northern Brazil, investigate capacity of biofilm production, and analyze association production with multiresistance intensity California Mastitis Tests (CMT) reactions that can make treatment more difficult cause misdiagnoses, respectively. Milk samples were collected from 23 farms located five municipalities state Acre. A total 339 crossbred cows tested by CMT, 109 animals (229...
