Prevalence of Community Acquired Methicillin Resistant Staphylococcus aureus Nasal Carriage among Children of Consultation: Experience of a Moroccan University Hospital

Background: The carriage of Staphylocoque aureus, including methicillin-resistant S. aureus (MRSA), is a ƐŝŐnŝĮcĂnƚ risk factor for subsequent staphylococcal ŝnĨĞcƟŽn͘ The nares are the most consistent sites of cŽůŽnŝnjĂƟŽn͘ The ŽbũĞcƟvĞ of this study was to determine prevalence for community acquired methicillin-resistant S. aureus (CA-MRSA) nasal carriage among a pediatric ƉŽƉƵůĂƟŽn as well as to ĮnĚ out ĂnƟbŝŽƟc ƐƵƐcĞƉƟbŝůŝƟĞƐ of isolated strains. WĂƟĞnƚƐ and methods: We conducted a ƉrŽƐƉĞcƟvĞ study from June 2017 to June 2018 on 300 children, who consulted in the ĚŝīĞrĞnƚ pediatric ƐƉĞcŝĂůƟĞƐ of Mohamed VI University Hospital of Marrakesh. Nasal swabs were collected from all the consultant children. The ŝĚĞnƟĮcĂƟŽn of nasal carriage of SA was performed in the microbiology laboratory of Mohamed VI University Hospital. Results: Staphylocoque aureus was isolated from the nares in 49 (16.3%) children, two (4%) isolates were cůĂƐƐŝĮĞĚ as CA-MRSA. The mean children age was 75, 14 months (p=0.05), a male predominance was nŽƟcĞĚ͘ The majority of SA carriers were from urban areas, it was noted a high carriage in living ƉĂƟĞnƚƐ with ĮvĞ or more people (p=0.024). nƟmŝcrŽbŝĂů ƐƵƐcĞƉƟbŝůŝƚy ƚĞƐƟnŐ of MRSA stains expressed a 100% resistance to cotrimoxazole, fusidic acid and ƐĞnƐŝƟvŝƚy to all other ĂnƟbŝŽƟcƐ͘ Conclusion: This study highlights the ƉŽƚĞnƟĂů for community MRSA ĂcqƵŝƐŝƟŽn in our context.
