Nasal Carriage of Methicillin-Resistant among Health Care Workers in Tertiary and Regional Hospitals in Dar es Salam, Tanzania. | LitMetric

AI Article Synopsis

  • A study conducted in Dar es Salaam, Tanzania, found that 41.4% of health care workers (HCWs) were colonized with Staphylococcus aureus, with 15.6% specifically carrying methicillin-resistant Staphylococcus aureus (MRSA).
  • MRSA was most prevalent among nurses and in specific hospitals, with high resistance rates observed against common antibiotics like kanamycin and gentamicin.
  • The study suggests urgent action is needed, such as enhanced infection control measures and routine MRSA screenings, to minimize the risk of MRSA transmission in hospital settings.

Article Abstract

Methicillin-resistant (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. 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 , 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 isolates ( ≤ 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.
