شيوع استافيلوكوكوس اوريوس در بين دانش آموزان سالم دبستاني شهرستان گرگان

Golden staphylococci is one of the most common factor in skin and systemic infection. About 30% of people are caning this bacterium in their skin and nose. Increased drug resistance in this microorganism and consequent infection, has gained the attention of scientific organization. Therefore we decided to determin the prevalence of nose carrier of this bacterium in healthy children in Gorgon schools. During the winter 1998 to March 1999 the sample has been taken from 1193 studentʹs nose with steril cotton swob. These results showed that in 194 samples (16.3%) staphylococci aureus has been isolated, .from these samples 114 cases belong to girls (16.1%) and 80 cases were boys (16.4%) that there is not a meaningful variation between them. The number of bacteria isolated from the villages children was 109 cases (17.6%) and in townʹs children was 85 cases (14.8%), also this difference did not show significant difference. The prevalence of carrier among the 6-12 years old was 12-25.3% which has got a significant meaning (Pc0.001). Antibiotic resistance in the isolated S.aureus were tested and result showed that 34.8% of samples are resistant to methicylin and 1.7% were resistant to vancomycin, only 4% were senseive to penicilline. Therefore with regard to the results of this investigation, further researches are recommended in relation between strainʹs of S.aureus that isolated from carrierʹs and strainʹs that isolated from patients and to determine their drug resistance in this region.
