materials and methods fifty mrsa isolates were collected from 200 clinical samples from three different educational hospitals in ahvaz, iran, and identified by biochemical tests including catalase, oxidase, tube coagulase, mannitol fermentation, and sensitivity to furazolidone, resistance to bacitracin, pyr test and voges-proskauer test. their resistance to methicillin was evaluated using the d...

patients and methods two-hundred and fifty-five clinical specimens were collected from four major provinces of iran. samples were cultured and the mrsa strains were subjected to polymerase chain reaction (pcr). the patterns of antibiotic resistance were determined using the disk diffusion method. results seventy-four out of 255 (29.01%) clinical samples were positive for mrsa. of the 74 mrsa st...

introduction: methicillin-resistant staphylococcus aureus (mrsa) is responsible for an increasing number of serious hospital- and community-acquired infections. usa300 is known to be the most common cause of community-acquired infections, but recently there have been some reports on hospital-acquired infections caused by this strain. methods: totally 171 isolates of s. aureus were collected fro...

conclusions the results of the present study indicate the presence of the pvl and fnb genes in the strains of s. aureus isolated from clinical specimens collected from the patients admitted to teaching hospitals in qazvin. considering the clinical significance of these organisms, and their potential in threatening public health systems, the identification, treatment, and infection control manag...

In the last decade, methicillin-resistant Staphylococcus aureus (MRSA) has been identified in livestock animals, such as swine, poultry, and veal calves, termed livestock-associated MRSA (LA-MRSA). LA-MRSA sequence type (ST) 398 strains can effectively infect colonize humans, with subsequent human-to-human transmission both community hospital settings. Unlike other countries, had not reported J...

BACKGROUND Panton-Valentine leukocidin (PVL-)producing Staphylococcus aureus is emerging as a serious problem worldwide. There has been an increase in the incidence of necrotizing lung infections in otherwise healthy young people with a very high mortality associated with these strains. Sporadic severe infectious complications after incision of Bartholin's abcesses have been described but invol...

Staphylococcus aureus is an important opportunistic pathogen responsible for a variety of diseases. Indiscriminate prescription of antibiotics caused severe antibiotic resistance especially against commonly used drugs. The present investigation was carried out to study the distribution of Panton-Valentine Leukocidin gene, SCCmec types and antibiotic resistance properties of meticillin-resistant...

THE discovery that many strainis of staphylococci produce a toxini (Neisser and XVNlechsberg, 19011; Kraus anid Pibream, 19062; Parker, 19243; and Burnet, 19294) has thrown fresh light on the problem of the treatment of staphylococcal lesions. From staphylococcal toxin, Panton, Valentine, and Dix (1931)5 successfully prepared staphylococcal toxoid. In 1933 Parish6 found that staphylococcal toxo...
