Methicillin-resistant Staphylococcus aureus (MRSA) among health care workers (HCWs) increases the risk of spreading the organism in hospital settings. A cross-sectional study was conducted between June and October 2016 among HCWs in tertiary and regional hospitals in Dar es Salaam, Tanzania, to determine the MRSA nasal carriage rate. Nasal swabs were collected from HCWs and cultured on mannitol salt agar. S. aureus was identified based on colonial morphology, Gram staining, catalase, coagulase, and DNase test results. MRSA was detected using the cefoxitin disk. Among 379 HCWs enrolled, 157/379 (41.4%) were colonized with S. aureus, of whom 59 (37.6%) were MRSA carriers giving an overall prevalence of 59/379 (15.6%). MRSA carriage was high among HCWs in Temeke (56.9%) and Amana (37.5%) regional hospitals. A high proportion of MRSA carriage was detected among nurses (35, 45.5%). MRSA isolates showed high resistance toward kanamycin (83.7%), gentamicin (83.1%), ciprofloxacin (71.2%), and trimethoprim-sulphamethoxazole (46.8%) compared to methicillin-sensitive S. aureus isolates (p≤0.001). In conclusion, we found a high nasal carriage of MRSA and resistance to commonly prescribed antimicrobial agents among HCWs. Implementation of infection control measures including contact precautions, urgent reporting of MRSA laboratory results, and routine MRSA screening of HCWs is highly needed to reduce MRSA spreading.

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.

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.

Background: The presence of Staphylococcus aureus in anterior nares of health care workers may serve as a major source of infection in hospital environment and act as a reservoir for the spread of Methicillin Resistant S. aureus between patients.Objective: The present study was conducted to determine the frequency of nasal carriage of S. aureus among the health care workers of Kathmandu Medical College Teaching Hospital and to assess the antibioticsusceptibility patterns of the Methicillin Resistant S. aureus isolates.Methodology: A total of 200 health care workers involved in the management of patients from the intensive care unit, Operation Theatre, postoperative wards, different wards and emergency department were screened for S. aureus by collecting their nasal swabs.Results: Out of 200 health care workers, only 10(5%) were S. aureus nasal carriers. Out of 10 S. aureus strains isolated six (60%) were methicillin sensitive S. aureuswhereas four (40%) were methicillin resistant S. aureus. The isolates were 100% sensitive to Linezolid, Vancomycin and Amikacin but showed highest resistant to Azithromycin (100%), followed by Cefixime (60%).Conclusion: This study concluded that 5% of health care workers were S. aureus carriers and proportion of Methicillin Resistant S. aureus and Methicillin sensitive S. aureus was 60% and 40% respectively.Journal of Kathmandu Medical CollegeVol. 7, No. 2, Issue 24, Apr.-Jun., 2018, page: 64-67

Background: Methicillin-resistant Staphylococcus aureus is one of the most common causes of nosocomial infections. Due to its multidrug resistant nature; infections due to Methicillin-resistant Staphylococcus aureus are often very difficult to treat. Colonized health care workers are the important sources of Methicillin-resistant Staphylococcus aureus. The objectives of this study were to determine the nasal carriage rate of Methicillin-resistant Staphylococcus aureus among health care workers at Kathmandu Medical College and Teaching Hospital, Nepal and to assess their antimicrobial susceptibility patterns.Methods: A cross sectional study was conducted among 252 health care workers from July to November 2013. Mannitol salt agar was used to culture the nasal swabs. Antimicrobial susceptibility testing was performed by Kirby- Bauer disc diffusion technique following Clinical and Laboratory Standards Institute guidelines. Methicillin-resistant Staphylococcus aureus strains were confirmed by using cefoxitin disc and by determining the minimum inhibitory concentration of oxacillin by agar dilution method.Results: Of 252 healthcare workers, 46(18.3%) were positive for Staphylococcus aureus among which 19(41.3%) were Methicillin-resistant Staphylococcus aureus carriers. Overall rate of nasal carriage of Methicillin-resistant Staphylococcus aureus was 7.5% (19/252).The higher percentages of lab personnel were nasal carriers of S. aureus (31.6%) and Methicillin-resistant Staphylococcus aureus (10.5%).The percentages of nasal carriage of S. aureus (35.7%) and Methicillinresistant Staphylococcus aureus (14.3%) were highest in the health care workers from post operative department. Higher percentage of Methicillin-resistant Staphylococcus aureus were susceptible toward amikacin (100%) and vancomycin (100%) followed by cotrimoxazole (84.2%).Conclusions: High rates of nasal carriage of S. aureus and Methicillin-resistant Staphylococcus aureus were observed among the healthcare workers, which indicate the need of strict infection control measures to be followed to control the nosocomial infections.
