A study of coagulase-negative staphylococci (CoNS) isolated from bovine mastitis for the presence of penicillin and methicillin resistance-encoding genes in the north west of Iran
Coagulase-negative staphylococci (CoNS) are often associated with bovine mastitis and may be resistant to antimicrobial therapy. The aim of the current study was to investigate the presence of blaZ (responsible for penicillin resistance) and mecA (responsible for methicillin resistance) genes among 108 CoNS belonging to 9 different species isolated from bovine mastitis in seven dairy herds (H1-...
متن کاملAntimicrobial susceptibility of coagulase-negative Staphylococci isolated from mastitic cattle in Brazil [Susceptibilidade antimicrobiana de cepas de Staphylococci coagulase-negativa isoladas de leite de bovinos com mastite no Brasil]
Mastitis is the most common and costly disease of dairy cows (Hortet and Seegers, 1998; Zafalon et al., 2007); this is also the single most common reason for antimicrobial use in dairy herds, since antimicrobial therapy is the major primary tool for mastitis control in lactating and dry cows. Recently, coagulase-negative Staphylococci (CNS) are increasing in importance as cause of bovine intram...
متن کاملFrequency of specific agr groups and antibiotic resistance in Staphylococcus aureus isolated from bovine mastitis in the northeast of Iran
Staphylococcus aureus is generally regarded as a leading cause of mastitis in dairy cattle. The aim of this study was to investigate the pattern of agr groups and any possible relationship between agr groups and antibiotic resistance among S. aureus strains isolated from bovine mastitis in Northeast of Iran. For this purpose, a total of 300 bovine mastitic mi...
متن کاملAntimicrobial Resistance of the Mastitis Pathogensin Dairy Cows
There has been a rapid awareness about multiresistant pathogens in the past 10 years and some bacteria are now resistant to most antimicrobial agents used in veterinary practice. Occurrence of multiresistant bacteria in milk from both dairy cows with high somatic cell count and clinical mastitis were analyzed. Multiple resistance of bacteria isolated from milk depends on bacteria species and is...
متن کاملSpecies distribution and in vitro antimicrobial susceptibility of coagulase-negative staphylococci isolated from bovine mastitic milk.
BACKGROUND Coagulase-negative staphylococci (CoNS) are the most common bovine mastitis causing bacteria in many countries. It is known that resistance for antimicrobials is in general more common in CoNS than in Staphylococcus aureus but little is known about the antimicrobial resistance of specific CoNS species. In this study, 400 CoNS isolates from bovine mastitic milk samples were identified...
