Abstract:
A total of 354 (8%) out of 4395 primary school pupils located in seven Lagos primary schools were positive for beta-haemolytic streptococci (BHS). Eighty-three (23%), 99 (28%) and 113 (32%) of the respiratory tract isolates and 25 (53%), 14 (30%) and seven (15%) of the skin-lesion isolates were identified as belonging to Lancefield groups A, C and G respectively. Prevalence rate of BHS in a rural school was different from that in urban schools.
