Abstract:
Background: Asymptomatic carriage of Staphylococcus aureus is common and one of the common sites (20-30%) is in the nose. On the other hand, it is a known cause for wide range of infectious disease. In current study, we evaluated the incidence of Staphylococcus aureus in the nostril of kids, in2 groups, first whose mothers were working in a hospital and second whose mothers were on other jobs in the kindergartens at the AJA University in 2018. Methods: In this cross-sectional study, all children aged 1-6 years were included. The demographic information was collected and Staphylococcus aureus was isolated and identified from nasal swabs via standard microbiologic methods. Result: In this study, 120 children were examined. The mean age of these children was 4.03 ± 1.04 years. Male: female ratio was 1.18:1. 76 (63 %) mothers were hospital’s staffs and 55% had direct contact with the patients. Nasal cultures were positive for Staphylococcus aureus in 24 (20%) samples, of which 4 (3.3%) were MRSA. there was no relation between age and sex of kids and also their mother jobs with positive results. Conclusion: Staphylococcus aureus is still a common human pathogen with a considerable morbidity and mortality. Methicillin-resistant staphylococcus aureus (MRSA) may be seen in nasal carriers and it is important to consider hygiene and parents job when we have kids in a day care centre such as kindergartens.
