Background: Methicillin resistant Staphylococcus aureus (MRSA) is a multidrug resistant organism emerging as a major cause of hospital acquired infection. In a healthcare setup a patient may acquire MRSA through the hands, clothes and equipments of health care workers. Screening of health care workers colonised with MRSA will be helpful in preventing the spread of this organism in a hospital. With this background the present study was undertaken to estimate the carriage rate of MRSA among healthcare workers in our hospital.Methods: Nasal swabs were collected from 120 health care workers working in Kalinga Institute of Medical Sciences (KIMS), Bhubaneswar during the study period of July- September 2017. The swabs were inoculated onto mannitol salt agar plates for isolation of Staphylococcus aureus. MRSA strains were identified by cefoxitin disc method. Antibiogram of MRSA strains was determined.Results: The prevalence of MRSA carriage among health care workers was 7.5% with the carrier rate being highest among nurses (10%). All the MRSA isolates were 100% resistant to penicillin. MRSA isolates were 90% resistant to amoxyclav, 60% to cotrimoxazole and erythromycin and 50% to clindamycin.Conclusions: Although the prevalence of MRSA among health care workers in our hospital is not alarming, it is important to emphasize the need for stringent hospital infection control policies to reduce the spread of MRSA to susceptible individuals.

Abstract INTRODUCTION: Resistance to antimicrobial agents is a major concern worldwide and is exemplified by the global spread of the Methicillin resistant Staphylococcus aureus (MRSA). Health care workers (HCWs) and asymptomatically colonized patients are important sources of nosocomial MRSA infections. AIMS AND OBJECTIVES: To determine the prevalence of MRSA colonisation, two hundred HCWs and 200 consecutive outpatients attending our tertiary care hospital were studied. MATERIALS AND METHODS: Two sterile pre-moistened cotton tipped swabs were used to collect specimens from their anterior nares. These were inoculated immediately on Blood agar with oxacillin, Mannitol salt agar with oxacillin and CHROM agar. Resistance to cefoxitin was confirmed by PCR by demonstration of mecA gene. Antibiotic susceptibility was determined by Kirby Bauer’s disc diffusion method and MIC of vancomycin by using broth dilution and Vitek-2 Compact system. RESULTS: The nasal carriage of MRSA among HCWs was found to be 7.5% and in outpatients 3%. All strains of MRSA from HCWs and outpatients grew on three selective media and mecA gene amplified in all of them. All the isolated strains of MRSA showed high degree of resistance to co-trimoxazole (93.3%), ciprofloxacin (80%) and erythromycin (66.66%). However, there was 100% susceptiability to vancomycin, teicoplanin, linezolid and Rifampicin. CONCLUSION: Although a direct casual relationship could not be established, it could be assumed that the transmission from colonised health care worker is responsible atleast in part for MRSA infection among patients. Therefore emphasis should be laid on strict implementation of standard infection control practices which would help in minimizing the carriage and transmission of MRSA in the hospital.

Increasing incidence of Methicillin-Resistant Staphylococcus aureus (MRSA) is a well-documented healthcare and community phenomenon of concern to medical and public health communities all over the world. One of the most important sources of MRSA infection in hospitals is health care workers (HCWs) through nasal or hands carriage. The aim of this study is to determine the rate of methicillin-resistant Staphylococcus aureus among HCWs. A cross-sectional study involving 102 HCWs was conducted at Alwahda hospital, Derna. Nasal and hand swabs were collected and cultured on Mannitol Salt Agar. Gram staining was performed on mannitol fermenting colonies. Slide catalase and coagulase were performed to identify S. aureus. An oxacillin and cefoxitin susceptibility test was carried out on Muller Hinton agar using the modified Kirby-Bauer disc diffusion method. Results: out of 102 healthcare workers, 46 (45.1%) carried S. aureus. The rate of methicillin resistance amongst all S. aureus isolates was 47.8 % (22/46) whereas 21.6 % (22/102) of all HCWs were identified as MRSA carriers. Nurses had the highest MRSA carriage with 53%, compared to other HCW. On the other hand, the highest rate of MRSA (75%) was seen in CCU workers followed by workers of pediatric and surgical wards (66%, 62% respectively). The high rate of nasal and hand MRSA carriage among healthcare workers, especially in high-risk wards, indicates the imperfection of infection control measures in our hospitals and the necessity to improve the infection control program.
