Ingestion of a cyst of Entamoeba histolytica will produce six trophozoites. Nematodes are cylindrical, bilaterally symmetrical and non-segmented. Mass chemotherapy is an efficient method of controlling soil-transmitted worms. The oocysts of Toxoplasma gondii that are passed out in the faeces of cats are immediately infective. Both Plasmodium falciparum and Plasmodium vivax produce quartan malaria. Schistosoma mansoni is only endemic in the African continent. Cryptosporidium and Isospora affect mainly immunocompromised persons and rarely immunocompetent children. The antennae of anophelines are pilose while those of culicines are plumose. Clinical manifestations of Plasmodium falciparum tend to be subclinical in pregnant mothers and children. Mosquitoes are definitive hosts of malaria.

More Information

Entamoeba histolytica trophozoites are typically produced four per cyst. Nematodes are indeed cylindrical and unsegmented. Schistosoma mansoni is also found in the Americas and the Middle East.
