A study has been made of 523 strains of staphylococci on the basis of biological properties, phage typing, and serology. The value of serology in the identification of pathogenic staphylococci has been assessed.

INTRODUCTION According to the results of different investigations, the opinion that isolate of coagulase-negative staphylococci by bloodcultures represents the blood infection in 10-12% patient. The aim of the work was to determine the number of patients with blood infection-sepsa induced coagulase-negative staphylococci isolated by bloodcultures. MATERIAL AND METHODS The research was done at...

introduction: drug resistant staphylococci are the most important agents of nosocomial infections. in this survey, effect of different antibiotics on these bacteria and their drug resistance was investigated. methods: the study included 500 strains of staphylococci. minimum inhibitory concentrations of all antibiotics was determined by the broth macro dilution technique and standard methods fro...

Clindamycin has been used successfully to treat pneumonia and soft-tissue infections caused by methicillin-resistant Staphylococcus aureus. However, inducible clindamycin resistance has been described as a cause of treatment failure of such infections. A total of 159 staphylococcal isolates from different clinical specimens from burn patients in Tripoli Burn Center were tested for inducible cli...

Lysozyme production is a frequent property of potentially pathogenic staphylococci. In the present study, 1,186 strains of human origin, 85 strains of animal origin, and 156 strains of Staphylococcus albus (epidermidis) were tested. Of 1,114 coagulase-positive strains of human and animal origin, 1,098 were lysozyme-positive (98.5%). On the other hand, of 157 coagulase-negative strains which, ba...

OBJECTIVES Integrons are thought to play an important role in the spread of antibiotic resistance. This study investigates class 1 and 2 integron-positive methicillin-resistant coagulase-negative staphylococci strains isolated in Iran and characterizes their patterns of antimicrobial resistance. METHODS Hundred clinical isolates of coagulase-negative staphylococci were characterized for integ...

Coagulase-negative staphylococci, particularly Staphylococcus epidermidis, are increasingly important causes of nosocomial infection. Microbiologists and clinicians no longer can afford to disregard clinical isolates of coagulase-negative staphylococci as contaminants. Accurate species identification and antimicrobial susceptibility testing, in a clinically relevant time frame, are important ai...

Necrosis of rabbit skin produced by thermal injury was found to result in a striking increase in local infectivity of staphylococci that were coagulase-positive and hemolytic, but no local increase in the infectivity of non-pathogenic staphylococci. Infection produced in necrotic burns extended beyond the area of burn and was characterized by hemorrhage, edema, and necrosis of contiguous normal...

The clinical importance of coagulase-positive staphylococci is well-known. In fact, Staphylococcus aureus is so often considered a pathogen that few laboratories appreciate that up to 25% of these strains isolated from blood cultures are actually contaminants from skin flora.' Conversely, coagulase-negative staphylococci have so long been considered an environmental contaminant that the pathoge...

A multiplex PCR was developed to detect the coagulase gene (coa; pathognomic of Staphylococcus aureus) and the mecA gene (characteristically encoding for methicillin resistance in staphylococci) in a single, rapid test. Suitable primers for the gene targets and an internal, amplification control were incorporated into a multiplex PCR assay, which was then optimized on a capillary air thermal cy...
