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 ÆÅÅnÅÄ®cÄ‚nÆš risk factor for subsequent staphylococcal ÅnĨĞcƟŽn͘ The nares are the most consistent sites of cŽůŽnÅnjĂƟŽn͘ The ŽbÅ©ÄžcÆŸvÄž 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 Ä®nÄš out Ä‚nÆŸbÅŽƟc ÆƵÆcĞƉƟbÅůÅÆŸÄžÆ of isolated strains. WÄ‚ÆŸÄžnÆšÆ and methods: We conducted a ƉrŽÆƉĞcÆŸvÄž study from June 2017 to June 2018 on 300 children, who consulted in the ÄšÅÄ«ÄžrÄžnÆš pediatric ÆƉĞcÅÄ‚Å¯ÆŸÄžÆ of Mohamed VI University Hospital of Marrakesh. Nasal swabs were collected from all the consultant children. The ÅĚĞnÆŸÄ®cĂƟŽn 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 cůĂÆÆÅĮĞĚ 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 ƉĂƟĞnÆšÆ with Ä®vÄž or more people (p=0.024). nÆŸmÅcrŽbÅĂů ÆƵÆcĞƉƟbÅůÅÆšy ƚĞÆÆŸnÅ of MRSA stains expressed a 100% resistance to cotrimoxazole, fusidic acid and ÆÄžnÆÅÆŸvÅÆšy to all other Ä‚nÆŸbÅŽƟcÆ͘ Conclusion: This study highlights the ƉŽƚĞnƟĂů for community MRSA Ä‚cqƵÅÆÅƟŽn in our context.
