Occasional reports over the past several decades have indicated that coagulase production by Staphylococcus aureus (Microcuccus pyogenes var. aureus), in various media could be enhanced by the addition of whole blood or plasma (Fisher, 1936). MIore recently, attempts have been made to produce special media which would permit the elaboration of coagulase but little success has been achieved (Lom...

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...

Encapsulated and nonencapsulated strains of Staphylococcus aureus which lack coagulase or clumping factor (bound coagulase), or both, were examined for the antigen associated with the fibrinogen-cell clumping reaction. Extracts of the cells were tested for the ability to react with fibrinogen or to inhibit fibrinogen precipitation. Antisera prepared against encapsulated (coagulase-positive, clu...

given the inappropriate use of antibiotics and prevalence of resistant bacteria, there is urgentneed for antibacterial drugs that have fewer side effects than antibiotics. satureja bachtiaricais a medicinal plant which had many uses in traditional medicine. in this research, the ethanolextract of leave of satureja bachtiarica is tested on coagulase-negative staphylococcus strains.materials and ...

conclusions vancomycin, but not teicoplanin, can be considered an effective antibiotic of choice for controlling infections caused by mdr cons in gorgan, depending on the bacterial species. background coagulase-negative staphylococci (cons) are clinically important, especially in nosocomial and neonatal infections. the increasing emergence of glycopeptide-resistant cons has made these agents th...

A Swedish bovine and a Dutch human phage set for coagulase-negative staphylococci were used to phage type coagulase-negative staphylococci isolated from bovine milk from Minnesota dairy herds. A comparison was also made of the deoxyribonuclease activity of coagulase-negative staphylococci isolated from bovine milk in Sweden and Minnesota. Of 133 Minnesota isolates, only one could be typed with ...

To examine contamination of donor eye preservation media with methicillin-resistant Staphylococcus aureus (MRSA), we studied the media to detect specific genes for MRSA by use of the polymerase chain reaction (PCR) method. The materials were 36 samples of donor eye preservation media (EP-II) in which donor eyes had been stored for keratoplasty. Polymerase chain reaction procedures were carried ...

OBJECTIVES Staphylococcus aureus is an important bacterial pathogen responsible for a variety numbers of nosocomial and community acquired infections. Biofilm formation is regarded as an important factor in the establishment of S. aureus infection. The contribution of the genetic background of S. aureus to biofilm formation is poorly understood. The aim of the present work was to genotype S. au...

INTRODUCTION Coagulase-negative staphylococci, commonly Staphylococcus epidermidis, cause 5% of native valve endocarditis. We describe a case due to Staphylococcus lugdunensis, a coagulase-negative staphylococcus identified in 1988, as a first report in Southeast Asia. It was previously misidentified as S. aureus because it is sometimes slide coagulase positive, but always tube coagulase negati...
