Document Summary
Up to 1/3 of diagnosed cases die despite treatment: falciparum. Co2 that we breath out: vivax, malariae, ovale, knowlesi. Infects duodenum negative stool samples to rule out infection. Colon ulceration may lead to systemic spread via bloodstream to liver, lungs, brain and produce giardia symptomology. Small, delicate ring forms (plate heads) indicate heavy parasitism. Likes to infect younger rbcs (bigger in size) Bradyzoite (slow, does not cause disease) and tachyzoite (active) form. Trypomastigote are the active form, have a c shape when fixed in blood. Amastigote form analogous to bradyzoite form of gondi. Distinct ova (flat on one side and ovoid on the other) Not hermaphrodites; - ova test therefore does not necessarily mean lack of infection. Any type of fever or anaesthesia causes migration of worms. Pulmonary phase: high eosinophilia (linked w/ allergic rxns) Tell of there presence via eggs but cannot speciate. Only need to take action if there is presence of anemia.
