A longitudinal study was conducted to determine the epidemiology of in 1,636 children in Nigeria. Oocyst prevalence ranged from 15.6% to 19.6% over one year. (34), (25), / (4), (5), rabbit genotype (5), cervine genotype (3), and (1) were identified by polymerase chain reaction–restriction fragment length polymorphism analysis. Glycoprotein 60 subgenotyping showed that 28 amplifiable isolates consisted of 12 subtypes that belonged to 5 subtype families (Ia, Ib, Id, Ie, and 1 novel subtype family, Ih) and 23 amplifiable isolates consisted of 6 subtypes that belonged to 4 subtype families (IIa, IIc, Iii, and IIm). Three isolates sub-genotyped by sequence analysis of the small subunit ribosomal RNA gene fragment were type 1. This study is the first one to genetically characterize species and subtypes in Nigeria and highlights the presence of a high diversity in this pediatric population.
