Rotavirus infection causes acute gastroenteritis in children younger than five years of age, and commonly occurring human rotavirus strains include G1 - G4 and G9 associated with P[4], P[6] and P[8]. In this study, of 6050 stool samples collected from a Private Pathology Practice in Pretoria, March 2010 - August 2011, 664 tested positive using Coris test-strips. Of these samples, 752 were retested using EIA and, results showed: Coris sensitivity was 93,7% and specificity 99,8%; the winter epidemic peaked in July of both years; more males and children under 30 months of age were particularly vulnerable to infections. Rotavirus-positive samples from Trichardt, Rustenburg and Middelburg were analysed by PAGE and RT-PCR showing circulating strains as mainly G8P[4] (60%) with short electropherotypes, G12P[8] (66%) with long electropherotypes, and G1P[8] at low incidence in the 2010/2011 seasons. These results suggest additional research to monitor the impacts of recently introduced rotavirus vaccines on changing strain profiles in South African communities / Life and Consumer Sciences / M.Sc.
