Pharyngeal swabs were obtained to detect the presence of GAS and blood samples were collected to determine elevated ASO titers in serum. A total of 351 asymptomatic primary school children were included in the study, and 91 (25.9%) of these were found to be GAS carriers. Of the 91 carrier students. ASO titers were elevated (greater than or equal to200 IU/ml) in 34 students (37%). Of the 260 non-carrier children. ASO titers were found as elevated (greater than or equal to200 IU/ml) only in 27 (10.3%) students. The difference between the ASO-positivity rate of the GAS carrier group (34 in 91 students) and that of the non-carrier group (27 in 260 students) was found to be statistically significant (P < 0.05). The finding of a significant relationship between ASO positivity and GAS carriage indicated that ASO measurement might be used together with thorat culture to identify, GAS carriers.eninfo:eu-repo/semantics/closedAccessASO TitersStreptococcusYmptomatic Throat CarriageTurkeyConference Object57627127215623954Q2WOS:000226311700009Q4
