Document Summary

Immature cysts = single nucleus divide to form quadrinucleate metacyst released in feces. Leave midgut transform into epimastigotes migrate to salivary gland. Trypanosoma cruzi: released in feces of vector (reduvid bug) causes chagas disease. Biol 414 life histories: formation of psedocysts; circulating trypomastigotes infect taken up by vector, transform into epimastigotes in midgut multiply, form metacyclic trypomastigote released via feces. Giardia lamblia: fecal oral route transmission cysts taken up trophozoites develop live in gut attach to lining using adhesive disc feed on mucus transform into cyst released. Zygote thick walled oocyst (sporulated) released via feces. In immunocompromised: zygote thin-walled oocyst autoinfection. Plasmodium vivax: anopheles takes blood meal injects sporozoites via saliva into bloodstream infect hepatocytes immediately via csp (circumsporozoite protein) Pseudogymoascus destructans: bats hibernate drop body temp fungus (psychrophilic) proliferate infection starts on appendages move in and around nose respiratory disease. Interrupts hibernation period causes heightened activity and inability to fly (penetrate wing)
