Primary community-associated methicillin-resistant Staphylococcus aureus (CA-MRSA) endocarditis has rarely been reported in healthy individuals without risk factors, such as skin and soft tissue infections, and intravenous drug abuse. We describe a case of infective endocarditis by CA-MRSA (ST72-PVL negative-SCCmec IVA) in previously healthy individuals with no underlying medical condition and ...

background and objective : the prevalence of community acquired methicillin resistant staphylococcus aureus (ca-mrsa) is increasing around the world. it involves healthy people and causes a variety of diseases. material and methods : this cross sectional study was conducted from september 2010 - june 2011 on children less than 14 years of ahvaz, southwest iran. the participants were selected wi...

In the United States, Staphylococcus aureus is the most common cause of skin and soft tissue infections. Methicillinresistant Staphylococcus aureus (MRSA) is resistant to ßlactam antibiotics, including penicillinase-resistant penicillins (methicillin, oxacillin, nafcillin) and cephalosporins, and has long been a recognized pathogen among hospitalized patients and persons with certain healthcare...

Staphylococcal cassette chromosome mec (SCCmec) types and Panton-Valentine leukocidin (PVL) gene carriage were compared among suspected community-associated methicillin-resistant Staphylococcus aureus MRSA (CA-MRSA) and health care-associated MRSA (HA-MRSA) isolates. CA-MRSA isolates carried the SCCmec type IV complex, and most were PVL positive. The HA-MRSA isolates carried the SCCmec type II ...

The impact and prevalence of antimicrobial drug resistance in rural community healthcare settings is uncertain. Prospective surveillance in 51 rural hospitals in Idaho and Utah examined the epidemiologic features of clinical cases of methicillin-resistant Staphylococcus aureus (MRSA) and vancomycin-resistant enterococci (VRE). Thirty-two cases of VRE were reported; for 6, the patient had no pri...

Background: Nasal carriage of Staphylococcus aureus has a key role in the epidemiology and pathogenesis of infection. In this study we aimed to investigate the occurrence of the methicillin resistant Staphylococcus aureus (MRSA )and mecA gene among healthy primary school boys in north of Iran.Material and methods: This cross-sectional study was conducted from January 2017 to July 2017 in Sari l...

Recurrent community-associated methicillin-resistant Staphylococcus aureus (CA-MRSA) skin infections are an increasingly common problem. However, there are no data on the efficacy of decolonization regimens. We prospectively evaluated 31 patients with recurrent CA-MRSA skin infections who received nasal mupirocin, topical hexachlorophene body wash, and an oral anti-MRSA antibiotic. The mean num...

We evaluated the activity of ceftobiprole against 100 community-associated methicillin-resistant Staphylococcus aureus (CA-MRSA) and 100 hospital-associated MRSA (HA-MRSA) isolates. Eight isolates were evaluated by time-kill studies for kill rate and potential for synergy with tobramycin. Ceftobiprole MIC(50) and MIC(90) values were 1 and 2 microg/ml, respectively, against CA-MRSA and HA-MRSA. ...

We investigated community-associated methicillin-resistant Staphylococcus aureus (CA-MRSA) skin infections among HIV-positive men who have sex with men. We performed a matched case-control study of 35 case patients and 76 control subjects. CA-MRSA skin infections were associated with high-risk sex and drug-using behaviors and with environmental exposures but not with immune status.

Community-associated methicillin-resistant Staphylococcus aureus (CA-MRSA) are increasingly causing infective endocarditis over the past decade. Here we report a healthy man who developed a severe acute infective endocarditis with systemic embolism caused by CA-MRSA. The strain was recovered from repeated blood cultures and was characterized using molecular detection and genotyping. The S. aure...
