Methicillin-resistant Staphylococcus aureus (MRSA) is an important human pathogen that causes serious infectious diseases and was endemic in hospitals by the late 1960s. Beginning with its first report in the late 1990s, the rapid emergence of community-associated MRSA (CA-MRSA) worldwide responsible for a wide spectrum of diseases ranging from minor skin infections to fatal necrotizing pneumon...
Panton-Valentine leukocidin (PVL) is a virulence factor of Staphylococcus aureus, which is associated with skin and soft-tissue infections and necrotizing pneumonia. To develop a rapid phenotypic assay, recombinant PVL F component was used to generate monoclonal antibodies by phage display. These antibodies were spotted on protein microarrays and screened using different lukF-PV preparations an...
BACKGROUND Necrotizing pneumonia due to Panton-Valentine leukocidin-producing strains of Staphylococcus aureus is associated with a high mortality rate. We sought factors associated with vital outcome in 50 cases occurring from 1986 through 2005. METHODS We compared the clinical and biological characteristics of 50 patients according to their vital outcome and examined the characteristics of ...
Pseudomonas aeruginosa and Staphylococcus aureus mixed-species biofilm infections are more resilient to biocide attacks compared to their single-species counterparts. Therefore, this study used an in vitro model recapitulating bacterial burdens seen in in vivo infections to investigate the interactions of P. aeruginosa and S. aureus in biofilms. RNA sequencing (RNA-seq) was utilized to identify...
Methicillin-resistant Staphylococcus aureus (MRSA) plays an important role in nosocomial infections including those in communities. MRSA enables colonization in the nares and throats of healthy people. In this study, investigation of MRSA prevalence from the throats of healthy subjects in southern Thailand revealed that among 153 isolates, 2 showed mecA+ genotype by PCR. One mecA+ isolate was s...
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...
