In a previous study we have shown that public buses in Oporto, the second largest city in Portugal, were highly contaminated with MRSA. Here we describe the results of a similar study performed in another urban area of Portugal-Lisbon, the capital. Between May 2011 and May 2012, hand touched surfaces of 199 public buses in Lisbon were screened for MRSA contamination. Subsequently, the hands of ...

addition, both PVL-positive spa t034 isolates contained genes associated with hlb-converting phages, namely sak, chp and scn. Although we did not have detailed epidemiological information on all nine patients, it is notable that three of the patients in this study had recent exposure to pigs. In other settings, isolation of CC398 MRSA has been strongly associated with exposure to livestock, inc...

OBJECTIVES We unexpectedly identified MRSA isolates carrying mecC (mecC-MRSA) from a Danish swine farm located in eastern Zealand. The objective of the present study was to investigate the origin of these isolates and their genetic relatedness to other mecC-MRSA isolates from Zealand. METHODS WGS was used to infer the phylogenetic relationship between 19 identified mecC-MRSA isolates from the...

During routinely screening (50.000 milk samples on an annual basis) 14 MRSA ST398 strains were identified in the period of January 2008 to September 2008 in 14 different dairy herds located in the provinces Overijssel and Gelderland, The Netherlands. Molecular analysis was performed by Cfr9I PFGE, ST398-specific diagnostic PCR, spa typing, SCCmec typing and Panton-Valentine Leukocidin (PVL) gen...

Recently, we [E.M.C. D’Agata, G.F. Webb, M.A. Horn, R.C. Moellering Jr., and S. Ruan, Modellingthe invasion of community-acquired methicillin-resistant Staphylococcus aureus into the hospital setting, Clin. Infect. Dis. 48 (2009), pp. 274–284] proposed a deterministic mathematical model to characterize the factors contributing to the replacement of hospital-acquired methicillin-resistant Staphy...

Community-associated methicillin-resistant Staphylococcus aureus (CA-MRSA) infections increased from 2000 to 2003 in hospitalized pediatric patients in Houston. CA-MRSA was associated with greater illness than was infection with methicillin-susceptible strains. Children with CA-MRSA were younger and mostly African American. Of MRSA isolates, 4.5% had the inducible macrolide-lincosamide-streptog...

Companion animals and horses, veterinary clinics As MRSA could be isolated comparatively frequently up to now from infection processes in horses and companion animals, further characterisation of the MRSA strains of these animal species is advisable. Clinical assessment depends on the results of this diagnosis. It is important that special care is exercised when treating these patients in order...

Virulent community-associated methicillin-resistant Staphylococcus-aureus (CA-MRSA) strains have spread rapidly in the United States. To characterize the degree to which CA-MRSA strains are imported into and transmitted in pediatric intensive care units (PICU), we performed a retrospective study of children admitted to The Johns Hopkins Hospital PICU, March 1, 2007-May 31, 2008. We found that 7...

The article brings to light an alarmingly high incidence of MRSA (88.9%). Considering the fact that phenotypic screening methods remain the backbone for detection of MRSA in clinical isolates (Babakir-Mina et al., 2012), the authors fail miserably in performing these tests according to CLSI guidelines. This therefore questions the reliability of the data generated making them highly misleading....

Methicillin-resistant Staphylococcus aureus is an established nosocomial pathogen (HA-MRSA, hospital acquired MRSA), but has recently begun to appear in the community (CA-MRSA, community acquired MRSA). The cause of resistance to methicillin and all other beta-lactam antibiotics is the mecA gene, which is situated on a mobile genetic element, the Staphylococcal Cassette Chromosome mec (SCCmec)....
