Fumagillin is also investigated as an inhibitor of malaria parasite growth. It is a member of the phylum Apicomplexa, which also includes the malaria parasite. Basigin is bound by the PfRh5 protein on the surface of the malaria parasite. The apicomplexans include "Plasmodium", the malaria parasite. Many insecticides, including DDT have been used to control mosquito species carrying the malaria parasite. Mitochondrial DNA (mtDNA) was found in the malaria parasite. The life cycle of the malaria parasite is particularly complex, presenting initial developmental problems. Asian Old World monkey malaria parasite species infect both colobine and macaque monkeys. The Malaria parasite can exert a selective pressure on populations. Another unconventional function of complex II is seen in the malaria parasite "Plasmodium falciparum". Other apicomplexan pathogens include the malaria parasite "Plasmodium" and the toxoplasmosis parasite "Toxoplasma". The bark showed activity against the rodent malaria parasite "Plasmodium berghei" in laboratory tests. The female mosquito of the genus "Anopheles" may carry the malaria parasite. "P. vivax" is the only indigenous malaria parasite on the Korean peninsula. Other apicomplexan pathogens include the malaria parasite "Plasmodium", and "Toxoplasma", the causative agent of toxoplasmosis.
