OBJECTIVES To analyse the possible relationship between consumption of old and new MRSA-active antibiotics and burden of MRSA in acute care hospitals in Catalonia during the period 2007-12. METHODS Fifty-four hospitals participating in the VINCat Programme were included. Proportion of MRSA (resistant isolates of Staphylococcus aureus per 100 isolates of S. aureus tested), incidence of new cas...

AIM To evaluate fusidic acid resistance pheno- and geno-typically in nasal carriage Staphylococcus aureus isolated from general practice patients in nine European countries. MATERIALS & METHODS Phenotypic fusidic acid resistance was determined by disc diffusion and MIC values, and genotypically by a PCR detecting fusA-E genes. The main analysis was performed on methicillin-susceptible S. aure...

OBJECTIVE To determine the frequency of methicillin resistant Staphylococcus aureus and its antimicrobial susceptibility pattern in patients reporting to Combined Military Hospital (CMH), Pano Aqil. STUDY DESIGN A non-interventional, cross-sectional study. PLACE AND DURATION OF STUDY Pathology Laboratory, Combined Military Hospital (CMH), Pano Aqil, from December 2005 to January 2008. MET...

The pH of the medium in which staphylococcal susceptibility to penicillins was determined was found to make a profound difference (128- to 8,000-fold) in the expression of "intrinsic" resistance, whereas beta-lactamase-mediated resistance was only slightly affected by pH; methicillin-resistant staphylococci that are beta-lactamase-negative are models of pure intrinsic resistance, and the common...

Background: Staphylococcus aureus is one of the most important agents causing nosocomial infections. Inducible clindamycin resistance is an important concern, because common laboratory tests could not detect it. Objectives: The aim of this study was to detect the inducible clindamycin resistance by D-test method. Materials and Methods: A total of 209 clinical S. aureus isolates were collected a...

A total of 15 of 101 (14.8%) nasal methicillin-resistant Staphylococcus aureus (MRSA) isolates exhibited mupirocin resistance (Mup(r)) compared with 1 of 154 (0.6%) methicillin-susceptible Staphylococcus aureus isolates. A total of 14 (93%) isolates exhibiting high-level Mup(r) belonged to a single clone. Horizontal plasmid transfer and transmission of Mup(r) strains contribute to a high incide...

results out of 238 samples, 5.88% were resistant to quinupristin-dalfopristin; 5.46% to linezolid; 60.92% to co-trimoxazole; 31.93% to doxycycline; 18.90% to tigecycline; 5.04% to vancomycin; 9.24% to mupirocin; 43% to oxacillin and 46.21% of our isolates were resistant to cefoxitin. conclusions coming across isolates with reduced susceptibility to quinupristin-dalfopristin and resistant to lin...

BACKGROUND Accurate and rapid detection of methicillin-resistant Staphylococcus aureus is very important in a clinical laboratory setting to avoid treatment failure. Conventional methods were compared against the gold standard polymerase chain reaction (PCR) technique to determine the best combination of the routine procedures. METHODOLOGY Methicillin resistance was investigated in 416 clinic...

background protein a is the virulence factors of staphylococcus aureus rolling in its pathogenesis, and its gene is used for typing. polymerase chain reaction-restriction fragment length polymorphism (pcr-rflp) with different enzymes has been used for this action. objectives in this study, we used bsp143i enzyme for digestion of the gene, coding protein a (spa gene) in s. aureus. the bacteria w...
