THE PREVALENCE OF PNEUMOCOCCI THROAT CARRIER IN HEALTHY SCHOOL CHILDREN IN GORGAN

Introduction:Streptococcus- pneumonia is the leading cause of respiratory tract infections in young children and elderly. Nasopharyngeal carriers of pneumococci in the densely populated school in the developing countries pane the way for high incidence of pneumococcal infections. In this study the distribution of streptococcus pneumonia among the school children in Gorgan carried out. Material & Method:During the period of February to March 1999, 1268 throat swabs were taken and cultured in blood agar, and assesed for isolation of Streptococcus pneumonia. Antibiogram for isolated S. pneumonia were done. Personal questionaire for all childeren were completed. Results:Out of 1268 throat swabs taken 138 isolates (10.9%) were positive for morphological and biochemical characteristics of S. pneumonia. The prevalence of penicillin resistance among the S. pneumonia isolates was found to be 14% while 93% and 80% were cephalexin and erythromycin sensitive respectively. The pharyngeal pneumococcal colonization of girls was found (14%) to be considerebly higher (p<0.0009) than those of boys (8% while lower prevalence of pneumococci were found in the throat isolates of children living in the city (7.5%) compared to those living in the rural areas (13.5%). Racehad no significant effect but we observed a notably higher colonization rate among children with jobless parents (16.7%) compared to those with working parents (7.3%). Discussion:Presence of penicillin resistant in this group is very important and showes need to antibiogram Jor all peeumococci strains that isolated
