Giardiasis and Malaria Comparison Chart Flashcards
causative agent of Giardiasis
Giardia lamblia
causative agent of Malaria
Plasmodium species
transmission of malaria
transmitted by anopheles mosquitos, only females feed on blood meals and involved in transmission
how does Giardiasis exist? (2)
dormant cyst form
feeding trophozoite form
Giardiasis is the ____ disease of the ______
protozoan disease of the digestive system
Malaria is the ______ disease of the _____
protozoan disease of the blood
signs and symptoms of Giardiasis
mild = innie = INI
severe = outy = vomit, lose weight, ab. cramps, diarrhea
mild: indigestion, intestinal gas, nausea
severe: vomiting, diarrhea, abdominal cramps, weight loss
incubation period of giardiasis
6-20 days
pathogenesis of giardiasis
- ingested cyst survives stomach passage
- trophozoites emerge from cysts in small intestine
- some attach to epithelium
- mucosal function is impaired by adherent protozoa and immune response
epidemiology of giardiasis (3)
- ingestion of fecally contaminated water
- low infectious dose
- person-to-person spread.
treatment and prevention of giardiasis
treatment: several antimicrobial medication options
prevention: boiling, filtering, or disinfecting drinking water
signs and symptoms of malaria
recurrent cycles of intense chills and fever alternating with feeling healthy
incubation period of malaria
varies with species; 6-37 days
pathogenesis of malaria
- protozoan enters hepatocytes and multiplies in them
- cells burst and release protozoa which causes fever
- organisms infect RBCs and differentiate in them
- spleen enlarges in response to removing large amount of foreign material and many abnormal blood cells from the circulation
- with P. falciparum infection, RBCs stick together and to walls of capillaries, blocking vessels and depriving tissue of O2
epidemiology of malaria
transmitted from person to person by bite of infected Anopheles mosquito
