aureus pathogenic lineages associated to mastitis in cattle (CC97 and CC133). Although healthy bovines do not represent a MRSA reservoir in Portugal, they are mainly colonized with S. Virulence determinants commonly found in mastitis were widely detected in carriage isolates: lukDE and hlgv (100%), hlb (76%), and lukM (35%). CC133 was associated to older animals ( p = 0.0025), whereas CC97 was isolated from calves ( p = 0.0016). Resistance to penicillin, rifampicin, and tetracycline was observed in 24%, 18%, and 6% of the isolates, respectively. Geralmente a colorao dorsal castanho-escuro e na zona ventral a pelagem mais clara (podendo mesmo ser branca). None of the isolates harbored the mecA or mecC genes. A marta tem uma estrutura tpica dos musteldeos, com a cabea larga e inclinada, orelhas pequenas e redondas, corpo comprido, patas curtas (com cinco dedos em cada uma das patas) e uma cauda comprida (Castells et al., 1993). aureus nasal carriage followed an increasing trend with animal age ( p = 0.0006). Overall, 54% of the screened animals were colonized with S. Marta Risco Ruiz - 2021 - Debates in Aesthetics 17 (1):tails.
The isolates were characterized by pulsed-field gel electrophoresis (PFGE), spa typing, SCC mec typing, and multilocus sequence typing and tested for antimicrobial susceptibility, presence of mecA and mecC genes, and virulence determinants.
A total of 52 samples (nasal, inguinal region, and milk) were obtained from bovine animals and analyzed for the presence of S. MRSA reservoirs in the animal setting in Portugal have been very poorly investigated, namely among animal husbandry. The nosocomial prevalence of methicillin-resistant Staphylococcus aureus (MRSA) in Portugal is close to 50% and remains one of the highest in Europe.
