  1. Plasmodium falciparum life cycle
    • bite from infected female anopheles mosquito
    • sporozoites enter the bloodstream and head to the liver
    • liver cell are infected and begin to develop merozoites
    • merozoites are released and infect human RBC's
    • in RBC's merozoites multiply and cause RBC to burst releasing more merozoites for infection and trigger fever
    • some become gametocytes that infect females when they feed off of humans
    • in female anopheles the male gametocyte fertilizes the female gametocytes
    • newly fertilized gametocytes encyst in anopheles gut wall where they rupture and release sporozoites that make their way to the salivary glands for delivery to new hosts
    • Amoeba
    • note pseudopodia also has no external shell
    • Paramecium¬†
    • notice cilia on outside also food vacuole- macro/micro nutrients

    • Symptoms - severe diarrhea
    • Contraction - ingestion of E. histolytica cyst through food or water
    • Found in - fecal matter


  5. what is the function of the scolex?
    • Taenia adult
    • Reproduction - monoiecious
    • Scolex - used for attachment to the intestinal wall

    • life cycle
    • eggs in feces in ground ingested by pigs
    • eggs hatch into larvae which penetrate the intestinal wall and make their way in to muscle tissue
    • humans eat raw or undercooked pork
    • scolex attaches to intestinal wall
    • Taenia reproduces and releases eggs into feces where the cycle begins again
    • Taenia Tapeworm
    • Reproduction - monoiecious
    • proglottids - sections of tapeworm where each one has a set of reproductive organs

    • life cycle
    • eggs in feces in ground ingested by pigs
    • eggs hatch into larvae which penetrate the intestinal wall and make their way in to muscle tissue
    • humans eat raw or undercooked pork
