The study evaluated cefoxitin disk diffusion tests breakpoints and their correlation to mecA gene PCR results for detecting Methicillin-resistant Staphylococcus intermedius Group (MRSP) isolates from dogs in Brazil. Agreement using proposed breakpoint (resistant ≤ 30 mm) was encouraging. The current study reinforces that an epidemiological breakpoint can be established to predict presence of MRSP.

Staphylococcus epidermidis is the most important member of coagulase negative staphylococci responsible for community and hospital acquired infections. Most clinical isolates of S. epidermidis are resistant to methicillin making these infections difficult to treat. In this study, correlation of methicillin resistance phenotype was compared with methicillin resistance (mecA) gene carriage in 55 ...

BACKGROUND Methicillin-resistant Staphylococcus aureus has been the most commonly identified pathogen in hand infections at urban centers, but the evolving antibiotic sensitivity profiles of methicillin-resistant Staphylococcus aureus are not known. The purposes of this study are to determine if multidrug resistance in methicillin-resistant Staphylococcus aureus is emerging and to provide curre...

We previously reported that Triton X-100 (TRX) reduced methicillin resistance in Staphylococcus aureus, although the degree of reduction varied among strains. One of the biological effects of TRX on S. aureus cells was enhancement of lipoteichoic acid (LTA) release. We investigated the correlation between the amount of LTA released and the degree of reduction in methicillin resistance induced b...

OBJECTIVE To determine the frequency of isolation of coagulase-negative staphylococci and their resistance to methicillin over a period of time. METHODS The descriptive cross-sectional study was carried out at Army Medical College, Rawalpindi, from June 2009 to May 2012, and comprised clinical samples mostly from patients admitted to the intensive care unit. They were inoculated onto appropri...

Clindamycin has been used successfully to treat pneumonia and soft-tissue infections caused by methicillin-resistant Staphylococcus aureus. However, inducible clindamycin resistance has been described as a cause of treatment failure of such infections. A total of 159 staphylococcal isolates from different clinical specimens from burn patients in Tripoli Burn Center were tested for inducible cli...

background: methicillin resistant staphylococus aureus (mrsa) is a cause of ‎nosocomial infections at intensive care unit (icu), which imposes a high mortality and ‎morbidity on the health care systems.‎ the objective of this study was to evaluate the role of mrsa in patients with clinically ‎suspected ventilator associated pneumonia (vap) in toxicological icu admitted ‎patients.methods: this c...
