The advent of community-associated methicillin-resistant Staphylococcus aureus (CA-MRSA) has been a worldwide threat to public health for the past decade. We report a fatal case of infective endocarditis caused by a non-USA300, Panton-Valentine leukocidin toxin-negative CA-MRSA clone. This is a serious case of CA-MRSA infection caused by a sequence type (ST) 72 clone, which is one of the common...
A 76-year-old man was admitted to a community hospital due to a persistent high fever. He became afebrile after the administration of broad-spectrum antibiotics, but developed heart failure due to progressive aortic and mitral valve insufficiency and was transferred to our hospital. Although sequential blood cultures were negative, a broad-range polymerase chain reaction targeting the bacterial...
A total of 19 methicillin-resistant Staphylococcus aureus (MRSA) isolates were investigated for Panton-Valentine leukocidin (PVL) toxin, PVL gene sequence variation and PVL-encoding phages. Whole genome sequencing was performed for all isolates. Analysis of MRSA isolates (n = 19) confirmed that most MRSA (n = 11) were positive for the PVL gene and were multidrug resistant. ST772-MRSA-V was the ...
Staphylococcus aureus is a common cause of musculoskeletal infections. Panton-Valentine leukocidin (PVL) is an exotoxin produced by S. aureus and is an important virulence factor. PVL-positive S. aureus infections have been associated with soft tissue infections and necrotizing pneumonia. In this case report, the clinical course of a 13-year-old boy who was admitted with right hip pain and feve...
We report the identification and characterization of three Staphylococcus aureus isolates recovered from throat and vaginal cultures, as well as from an axillary abscess, of a 17-year-old female who died of tampon-related toxic shock syndrome. The three S. aureus isolates were unrelated as determined by pulsed-field gel electrophoresis. The vaginal isolate was mecA, Panton-Valentine leukocidin,...
Most of the efforts in elucidating the molecular relatedness and epidemiology of Staphylococcus aureus in Malaysia have been largely focused on methicillin-resistant S. aureus (MRSA). Therefore, here we report the draft genome sequence of the methicillin-susceptible Staphylococcus aureus (MSSA) with sequence type 1 (ST1), spa type t127 with Panton-Valentine Leukocidin (pvl) pathogenic determina...
Methods A total of 20 isolates of Staphylococcus aureus were isolated from 25 cases of breast abscess from a tertiary hospital during January 2010-October 2010. Isolation was done by culturing the pus sample drained from the abscess with 16 gauge needle. The S. aureus isolates were screened for susceptibility to various antibiotics including cefoxitin, clindamycin, fusidic acid, mupirocin, vanc...
In the human lower respiratory tract, influenza A (INFA) can activate an inflammatory response that interferes with the innate immune response to bacterial pathogens, increasing the probability of subsequent infection by opportunistic organisms such as methicillin-susceptible (MSSA) and methicillin-resistant Staphylococcus aureus (MRSA).1,2 Some hypervirulent strains of communityacquired and ho...
