Answer 8

6-20 days

Question 9

pathogenesis of giardiasis

Answer 9

1. ingested cyst survives stomach passage
2. trophozoites emerge from cysts in small intestine
3. some attach to epithelium
4. mucosal function is impaired by adherent protozoa and immune response

Question 10

epidemiology of giardiasis (3)

Answer 10

• ingestion of fecally contaminated water
• low infectious dose
• person-to-person spread.

Question 11

treatment and prevention of giardiasis

recurrent cycles of intense chills and fever alternating with feeling healthy

Question 13

incubation period of malaria

Answer 13

varies with species; 6-37 days

Question 14

pathogenesis of malaria

Answer 14

1. protozoan enters hepatocytes and multiplies in them
2. cells burst and release protozoa which causes fever
3. organisms infect RBCs and differentiate in them
4. spleen enlarges in response to removing large amount of foreign material and many abnormal blood cells from the circulation
5. with P. falciparum infection, RBCs stick together and to walls of capillaries, blocking vessels and depriving tissue of O2
