BACKGROUND A high proportion of staphylococci isolated from pigs affected with exudative epidermitis were found to be resistant to β-lactam antimicrobials. The primary objective of this research was to investigate and characterize β-lactam resistance in Staphylococcus hyicus, Staphylococcus aureus and other staphylococci isolated from these pigs. RESULTS The antimicrobial resistance patterns ...

We analyzed 69 bacterial isolates, comprising seven species of gram-negative bacterial rods and three species of coagulase-negative staphylococci, recovered from both the hands of caretakers and their environment in households sampled in upper Manhattan. Repetitive sequence-based PCR and dendrogram analysis were used to determine strain similarity. Greater than 25% of individual species of Acin...

aims: it is very important to detect the coagulase-negative staphylococci, which produce the hospital infections. being one of the most expensive and time-consuming stages before the polymerase chain reaction (pcr), dna extraction is one of the primary stages of pcr. then, it should be noticed that the elimination of the stage might save time and costs. the aim of this study was to compare two ...

The addition of NaCl to cation-supplemented Mueller-Hinton broth increased the MICs of gentamicin, amikacin, and netilmicin for coagulase-positive and -negative staphylococci in a concentration-dependent manner. At 2% NaCl, geometric mean MICs were elevated 14.1- to 25.6-fold. Mueller-Hinton broth containing added NaCl should not be used for testing the susceptibility of staphylococci to aminog...

Thirty-nine Staphylococcus isolates with different mechanisms of resistance were recovered from the feces of 50 healthy children and tested for their susceptibilities to 17 antibiotics. The percentages of resistance of the staphylococci to some antibiotics were as follows: penicillin, 87%; erythromycin, 64%; tobramycin, 36%; tetracycline, 20.5%; kanamycin, 15%; and gentamicin, 13%. The mecA gen...
