Staphylococcus aureus is a gram positive coccus responsible for severe morbidity and mortality as it causes community and hospital acquired infections. The Methicillin resistant Staphylococcus aureus is responsible for several difficult to treat infections in human. Objectives: To find out Frequency of Methicillin resistant Staphylococcus aureus in Patients in a tertiary care hospital of Lahore. Study Design: Cross-sectional study. Setting: Tertiary care (Services Hospital) Lahore. Period: Four months from 1st August 2017 to 30th November 2017. Material & Methods: A total of 2534 isolates were obtained during the period (1 August 2017 to 30 November 2017) from patients at a tertiary care hospital of Lahore. Specimen were inoculated on blood agar plates, strains obtained were confirmed for Staphylococcus aureus using conventional biochemical tests and oxacillin disk test was performed to confirm methicillin resistant Staphylococcus aureus. Result: Out of 104 Staphylococcus aureus isolates, methicillin resistant Staphylococcus aureus was 46 (44.2%) and methicillin sensitive Staphylococcus aureus was 58 (55.8%). Conclusion: Methicillin resistant Staphylococcus aureus is a big challenge for current health care system and this may be a cause of morbidity and mortality in community and hospital patients.

Introduction: Methicillin resistant Staphylococcus aureus (MRSA), the most common cause ofnosocomial infection has been a major cause of morbidity and mortality around the world. They arenormally resistant to most of the antibiotics used in clinical practice. This study has been carried outto fi nd out the resistance pattern among S. aureus.Methods: During November 2007 to June 2008, clinical samples from patients with nosocomialinfection were processed for culture and sensitivity following standard methodology in microbiologylaboratory, Tribhuvan University teaching hospital, Kathmandu, Nepal.Results: Among 149 Staphylococcus aureus isolates, highest resistance was observed against Penicillin(91.94%) followed by Fluoroquinolone (61.74%), Erythromycin (52.94%), Gentamicin (46.98%),Cotrimoxazole (42.95%), Tetracycline (40.94%) and others, whereas susceptibility was observedmaximum against Chloramphenicol (94.85%) followed by Rifampicin (92.61%), Tetracycline(59.06%), Cotrimoxazole (57.04%), and others. None of the isolates were resistant to Vancomycinand Teicoplanin. Of these isolates 44.96 % of the isolates were Methicillin resistant S. aureus (MRSA).Resistance to Penicillin, Fluoroquinolone, Erythromycin, Gentamicin, Co-trimoxazole and Tetracyclinewere associated signifi cantly with MRSA isolates (X2= 8.779, p<0.05, X2= 74.233, p<0.05, X2= 84.2842,p<0.05, X2= 108.2032, p<0.05, X2= 88.1512, p<0.05 and X2= 79.1876, p<0.05 respectively). Althoughmost of the Methicillin sensitive S. aureus (MSSA) isolates were susceptible to both Rifampicinand Chloramphenicol, only Rifampicin susceptibility was signifi cantly associated with them (X2=10.1299, p<0.05). Among three Biochemical tests for the detection of β lactamase detection namelychromogenic, iodometric and acidimetric test, chromogenic test method had highest sensitivity andspecifi city.Conclusions: Since MRSA comprised a greater part of S. aureus isolates and were multi-resistant,patients infected by such strains should be identifi ed and kept in isolation for hospital infectioncontrol and treated with second line of drug like vancomycin.Key Words: β lactamase, methicillin resistant Staphylococcus aureus,methicillin sensitive Staphylococcus aureus, resistance pattern

 Objective: The aim of this study was to find the prevalence of methicillin-resistant Staphylococcus aureus (MRSA) carrier status in anterior nares and hands of health-care professionals working in orthopedic wards of a tertiary care hospital and to decolonize them to reduce spread of MRSA to their patients.Methods: The study was conducted in a super specialty, tertiary care teaching hospital. The samples were collected from anterior nares, palm, web spaces, and fingertips of 140 health-care professionals (48 doctors, 74 nurses, and 18 technicians) working in orthopedic wards using sterile pre-moistened swabs. MRSA carrier status was identified by Kirby-Bauer disc diffusion method.Result: Most (76.4%) of the health-care professionals were <30 years of age and 51% were male. MRSA in anterior nares of doctors was 4.3%, nurses 1.4%, and technicians 0.7% and none had MRSA in their hands. Methicillin-sensitive Staphylococcus aureus (MSSA) growth was more among nurses (nurses - 5.7%, doctors - 2.1%, and technicians - 1.4%) in anterior nares. In addition, 1.4% nurses’ hands were colonized with MSSA. Both MRSA and MSSA carriers were decolonized effectively and repeat sampling showed no growth.Conclusion: Health-care professionals have a greater chance of transmitting MRSA to patients and orthopedic patients are more susceptible for infection. Although MRSA carrier status was not very high among orthopedic health-care professionals compared to previous studies, it cannot be ignored. Nasal mupirocin and bath with chlorhexidine soap were effective in decolonization. Periodic screening and treatment of colonizers would help in elimination of MRSA carriage.
