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...

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...

This study characterizes 1,984 methicillin-resistant Staphylococcus aureus (MRSA) isolates collected in 2005 and 2006 from normally sterile sites in patients with invasive MRSA infection. These isolates represent a convenience sample of all invasive MRSA cases reported as part of the Active Bacterial Core surveillance system in eight states in the United States. The majority of isolates were fr...

Staphylococcus aureus is a major cause of infections. Toxic shock syndrome toxin (TSST-1) and Panton-Valentine leukocidin (PVL) are associated with severe clinical syndromes. S. aureus colonizing isolates recovered from healthcare workers and patients in the intensive care unit (ICU) of a university hospital comprising Group A were compared with those from adult non-ICU carriers (Group B). mecA...

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 ...

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...

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...
