methicillin-resistant staphylococcus aureus (mrsa) is a major cause of nosocomial infections all around the world. mrsas are usually present in health care centers and hospitals. nowadays methicillin-resistant mrsas in two groups of healthcare associated mrsa (ha_mrsa) and community associated mrsa (ca_mrsa)were studied. predisposing factors for ha_mrsa infections included hemodialysis, surgery...
background: methicillin-resistant staphylococcus aureus (mrsa) is a major cause of nosocomial and community infections that are becoming increasingly difficult to combat, because of emerging resistance to all classes of antibiotics. moreover panton-valentine leukocidin (pvl) is an important virulence factor in s. aureus and causes white blood cell destruction, necrosis and accelerat...
Background and Objective: Panton-Valentine leukocidin (PVL) toxin is a hemolytic exotoxin that increases the permeability of the cell membrane, thus causing lysis of leukocytes and tissue necrosis. Collagen-binding protein (Cna) adhesion Staphylococcus aureus is responsible for binding to collagen and the major virulence factor in arthritis and osteomyelitis. The purpose of this study was to in...
Background and Objective: Staphylococcus aureus is a major pathogen of human in the world. Methicillin-resistant Staphylococcus aureus is associated with nosocomial infections. Recently, staphylococcal infections have been associated with the community. The purpose of this study was to isolate and identify Staphylococcus aureus virulence Panton-Valentine leukocidin (PVL) and methicillin...
To characterize the clinical and bacteriologic characteristics of community-acquired methicillin-resistant Staphylococcus aureus (CA-MRSA) infections, we reviewed 14 cases that were diagnosed in previously healthy patients during an 18-month period in France. Eleven patients had skin or soft-tissue infections. Two patients died of CA-MRSA necrotizing pneumonia. A case of pleurisy occurred in a ...
Community-associated methicillin-resistant Staphylococcus aureus is a frequent cause of skin and soft-tissue infections and is increasingly identified as a cause of pneumonia in immunocompetent patients. Panton-Valentine leukocidin, one of several leukocytotoxic peptides secreted by these cocci, is associated with increased virulence. A cluster of 3 unrelated patients with fatal pneumonia presu...
Panton-Valentine leukocidin (PVL) is associated with staphylococcal skin and pulmonary infections. Community dissemination of PVL-producing Staphylococcus aureus strains constitutes a public health concern. Family transmission and spread of community-acquired leukocidin-positive methicillin-susceptible S. aureus ST152 isolates associated with severe clinical symptoms are herein described. Remar...
test; bioMérieux). DNA was extracted from cultures grown on agar plates and amplified following a previously described protocol (1). The following oligonucleotide primer sequences were used: luk-PV1, 5′-ATCATTAGGTAAAATGTCTGGACATGATCCA-3′; luk-PV2, 5′-GCATCAAGTGTAT T G G ATA G C A A A A G C 3 ′ . Polymerase chain reaction products were sequenced commercially and submitted to GenBank (accession n...
Staphylococcus aureus (SA) remains a major cause of nosocomial and community-acquired infections worldwide. Nasal carriage of this bacterium among hospital personnel constitutes an important source for nosocomial infections. A cross-sectional study enrolling the whole medical student population (n=387) of the School of Medicine at the Universidad de Cartagena, Colombia, was conducted to evaluat...
