Fig. 3From: Non-falciparum malaria in Dakar: a confirmed case of Plasmodium ovale wallikeri infection Plasmodium ovale subtyping nested PCR targeting potra gene. In nest 1, primer pair PoTRAfwd3 and PoTRArev3 bind a 787-bp fragment. Using the internal primers PoTRAfwd5 and PoTRArev5, P. ovale wallikeri and P. ovale curtisi (245 to 355 bp) can be differentiated. The 245 fragments correspond to P. ovale wallikeri.
