1.Falcipram gametocyte Banana shape P.f gametocytes • Vector: female Anopheles mosquito • Mode of infection: injection of sporozoite during Anopheles bite.
2.Plasmodiumring stage • Diagnosis: blood film (thin and thick) • Vector: female Anopheles • Infective stage: Sporozoite
3.Trichomonas vaginalis • Diagnosis: vaginal, urethral smear, occasionally in urine analysis • Trophozoite is the infective stage. • transmitted sexually.
4. Eggs of Taenia species • -T.saginata • -T. solium • -Echinoccus granulosus
5.Taenia saginata (adult tape) • Diagnosis: stool examination for - eggs - gravid segments. • Infective stage : cysticercus bovis-in under cooked meat (beef). • Adult habitat small intestine
6.Soft tick • Relapsing fever (endemic). • Tick paralysis
7.Hardtick • Rocky mountain spotted fever • Q fever • Babesiosis
8.Adult Fasciola hepatica • Diagnosis :egg in -stools examination -duodenal aspirate. • Infective stage : encysted metacercaria (on water plants). • Habitat : biliary passage in liver.
9-FemaleTrichuris trichiura (whip worm) • Diagnosis : egg in stools • Infective stage, mode of infection: ingestion of embryonated egg in soil.

10.Enterobius vermicularis egg (Pin worm,Oxyuris worm) • Diagnosis: Scotch tape preparationto collect eggs from perianal area and microscopical examination.
11.Schistosoma haematobium egg (Urinary schistosomiasis) • Diagnosis: - Urine analysis - Serology in chronic cases. • Infective stage :cercaria in water penetrate skin. • Pathology : periportal fibrosis. ppf
12. Schistosoma mansoni egg in stools specimen (intestinal schistosomiasis) • Other methods of diagnosis : - rectal swab . - rectal snip biopsy. - serology: to detect antibodies in patient serum.
13.Leishmania donovani bodies in smear(skin,B.M,spleen) (amastigotes) • Vector : sand fly . • Infective stage: promastigote. • for diagnosis of leishmaniasis Culture smear amastigotes from (skin ,BM, spleen) on NNN media grow and multiply in promastigote form.
