Prevalence of methicillin-resistant staphylococcus aureus colonization in children admitted to Motahari hospital of Urmia
Background and Objective: Staphylococcus aureus is an important bacteria associated with a range of infectious diseases in children and adults. Over-prescription of antibiotics effective in this bacterium in recent years has caused a special type of this species, called methicillin-resistant staphylococcus aureus (MRSA). It is considered as major problem to health systems around the world. The research was conducted to evaluate the prevalence of MRSA colonization in patients admitted to the infectious ward of educational-medical center of Shahid Motahari Hospital of Urmia. Methodology: This research is a cross-sectional analytical study. Samples were prepared from the anterior part of the nose and they were cultured on Mannitol-Celtic-Agar culture medium (Tian Biotech, India) after placing them in a Stuart transport medium. Samples were examined by microbiologist after incubation. Yellow grown colonies indicated the mannitol fermentation and they were selected for catalase and coagulase testing. Clones confirmed by these tests were isolated as staphylococcus aureus to measure the susceptibility to methicillin. SPSS version 21 software was used for statistical analysis. Results: The results of this research revealed that staphylococcus is a resistant and growing bacterium and it is still found in treatment centers. Antibiotic use has a significant relationship with positive culture results of MSSA (methicillin-susceptible staphylococcus aureus) and MRSA (methicillin-resistant staphylococcus aureus). Screening the children is required in terms of type of antibiotic use. Conclusion: Most of children admitted to the medical centers are often carriers of Staphylococcus aureus bacterium. Thus, screening the children in terms of Staphylococcus aureus is necessary by care centers in community and educational centers (schools, kindergartens).
