Absolute dependence on mecA gene as the defining standard in determining the resistance of S. aureus to methicillin became the subject of distrust by many researchers. The present study aimed to determine the frequency of mecA gene in methicillin resistant S. aureus (MRSA) isolates using polymerase chain reaction and to correlate its presence to conventional method. In this regard, two hundred ...

BACKGROUND AND OBJECTIVES Staphylococcus aureus is a versatile organism causing mild to life threatening infections. The major threat of this organism is its multidrug resistance. The present study was carried out to investigate in - vitro activity of conventional antibiotics routinely prescribed for methicillin resistant S. aureus (MRSA) and methicillin sensitive S. aureus (MSSA) infections in...

Clinical samples from 250 pregnant women undergoing screening for rectovaginal group B streptococcus colonization were evaluated concurrently for the presence of methicillin-resistant Staphylococcus aureus (MRSA). Overall, S aureus was detected in 21.6% of the women; 53.7% of the isolates were MRSA. Despite a lack of risk factors for MRSA colonization, rectovaginal MRSA was detected in 10.4% of...

In The Netherlands a new reservoir of MRSA has recently been identified in pigs and veal calves upon which the 'Dutch Working Party on Infection Prevention' modified the national MRSA guidelines. In June 2006 a new group at risk of MRSA carriage was included, consisting of patients that reported direct exposure to living pigs or veal calves. After the implementation of this modification in a tr...

conclusions resistance to oxacillin and other antibiotics was high, and most of the isolates were found to be multi-drug resistance (mdr). plasmid analysis of representative s. aureus isolates also demonstrates the presence of a wide range of plasmid sizes, with no consistent relationship between plasmid profiles and resistance phenotypes. regular surveillance of hospital infections and monitor...

BACKGROUND & OBJECTIVE Community acquired methicillin resistant Staphylococcus aureus (CA-MRSA) is a major global problem. Colonization rates of MRSA in the community have been reported to range from 0 to 9.2 per cent. The present study was conducted to detect S. aureus nasal colonization and prevalence of MRSA in children (5 to 15 yr) in an Indian community setting of rural, urban and semiurba...

A new methicillin-resistant Staphylococcus aureus (MRSA) clone related to pig and cattle farming was detected in the Netherlands. We investigated the extent of S. aureus presence in meat and found 36 S. aureus strains in 79 samples. Two strains were MRSA; 1 was multilocus sequence type 398, the clone related to farming.
