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 کاملAntibiotic Resistance in Staphylococcus aureus and Coagulase Negative Staphylococci Isolated from Goats with Subclinical Mastitis
Antimicrobial resistance patterns and gene coding for methicillin resistance (mecA) were determined in 25 S. aureus and 75 Coagulase Negative Staphylococci (CNS) strains isolates from half-udder milk samples collected from goats with subclinical mastitis. Fourteen (56.0%) S. aureus and thirty-one (41.3%) CNS isolates were resistant to one or more antimicrobial agents. S. aureus showed the highe...
متن کاملCoagulase-negative staphylococci as cause of bovine mastitis- not so different from Staphylococcus aureus?
In this review of the literature, mastitis-causing coagulase-negative staphylococci (CNS) and Staphylococcus aureus are compared. Staphylococci are the bacteria most commonly isolated from bovine mastitis, and CNS are now predominant over S. aureus in most countries. CNS include various species, but only a few prevail in bovine mastitis. S. aureus can cause clinical mastitis, but often causes s...
متن کاملMacrolide-lincosamide-streptogramin resistance phenotypes and genotypes of coagulase-positive Staphylococcus aureus and coagulase-negative staphylococcal isolates from bovine mastitis
BACKGROUND There are limited data available on macrolide-lincosamide-streptogramin (MLS) resistance of Staphylococcus aureus (S. aureus) and coagulase-negative staphylococci (CoNS) from bovine milk in China. To address this knowledge gap, MLS resistance was determined in 121 S. aureus and 97 CoNS isolates. Minimum inhibitory concentrations (MICs) of MLS antibiotics were determined by an agar di...
متن کاملA high prevalence of tylosin resistance among Staphylococcus aureus strains isolated from bovine mastitis
The macrolides appear to have considerable effects for treatment of bovine mastitis because of excellent diffusion into the mammary gland, long half-life, low protein binding, high intracellular concentration and lipid solubility. Acquired resistance to macrolides in Staphylococcus aureus is primarily related to target-site modification through acquisition of an erm gene. In t...
