Antibiotic Resistance of Staphylococcus Aureus and Coagulase-negative Staphylococci Isolated from Bovine Mastitis
The antibiotic susceptibility test was carried out on 103 Staphylococcus aureus and 136 coagulase-negative staphylococci (CNS) strains. Only 35 of the isolates were susceptible to all antibiotics tested, while the remaining 204 isolates were resistant at least to one of the antibiotics. Among staphylococci, 18 isolates of S. aureus and 31 isolates of CNS were found phenotypically resistant to m...
متن کاملA 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 کاملMolecular identification of coagulase-negative staphylococci isolated from bovine mastitis and detection of β-lactam resistance.
INTRODUCTION Bovine mastitis is a frequent cause of economic loss in dairy herds. Coagulase-negative staphylococci (CoNS) are increasing in importance as causeof bovine intramammary infection (IMI) throughout the world in recent years. CoNShave been isolated from milk samples collected from cows with clinical andsubclinical mastitis in several countries. Identification of mastitis pathogensis i...
متن کاملAntibiotic Resistance Pattern and Detection of mecA Gene in Staphylococcus aureus Isolated from Iranian Hamburger Samples
Background: Among the bacteria that cause food poisoning, Staphylococcus aureus is one of the most common causes of food poisoning worldwide. The aim of this study was to investigate the presence of S. aureus strains in Iranian hamburgers, analysis of their antibiotic resistance pattern, and molecular detection of mecA gene in isolated strains. Methods: A total of 100 Iranian handmade (traditi...
متن کاملPrevalence and Antimicrobial Susceptibility of Coagulase- Negative Staphylococci isolated from Bovine Mastitis
The study was carried out to investigate the prevalence and antimicrobial susceptibility of Coagulase-Negative Staphylococci isolated from Bovine Mastitis in and around Dharwad region. A total of 310 samples were screened and 180 confirmed Coagulase-Negative Staphylococci were obtained. The antimicrobial susceptibility of CoagulaseNegative Staphylococci against 10 antimicrobial agents was teste...
