There are indications that livestock-associated MRSA CC398 has a reduced human-to-human transmissibility, limiting its impact on public health and justifying modified control measures. This study determined the transmissibility of MRSA CC398 from livestock veterinarians to their household members in the community as compared to MRSA non-CC398 strains. A one-year prospective cohort study was per...

BACKGROUND In Latin America, few studies have been carried out on methicillin-resistant Staphylococcus aureus carriage in the pediatric population. We conducted a survey of nasal S. aureus carriage in neonates and in children attending the pediatric outpatient clinics in a large Brazilian city with high antimicrobial consumption. METHODS Pernasal swabs of neonates were collected upon admissio...

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 presents a synthetic molecular characterization of the methicillin-resistant Staphylococcus aureus and describes the most important community-acquired methicillin-resistant Staphylococcus aureus (CA-MRSA) clones that circulate nowadays in the world: the main molecular and epidemiological characteristics, as well as notions related to the clinic of infections produced by these clones...

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)....

Although antibiotics from different classes are frequently prescribed in combination to prevent the development of resistance amongst Cystic Fibrosis (CF) respiratory pathogens, there is a lack of data as to the efficacy of this approach. We have previously shown that a 4:1 (w/w) combination of fosfomycin and tobramycin (F:T) has excellent activity against CF pathogens with increased activity u...

The genotypes and oxacillin resistance of 420 S. aureus isolates from pigs (n = 203) and pork (n = 217) were analyzed. Among 18 spa types detected in S. aureus from pig t011, t021, t034, t091, t318, t337, and t1334 were the most frequent. Among 30 spa types found in S. aureus isolates from pork t084, t091, t499, t4309, t12954, and t13074 were dominant. The animal S. aureus isolates were cluster...

OBJECTIVES Methicillin-resistant Staphylococcus is a growing problem in intensive care units (ICUs). The aim of this study was to describe the epidemiology of methicillin-resistant Staphylococcus isolates in a cardiac surgical ICU over a 5-year period and to determine the risk factors and outcome of this condition. METHODS During the period from January 1998 to July 2003, the clinical data of...
