10
Q
A
ECHINOCOCCUS
E. granulosus (dog) = cystic
E. multiloculari (cats)
E. multilocularis (dogs + cats) = alveolar
- Definitive host : dogs, cats
- Eat cyst-containing organs from intermediate hosts
- Adults settles in the intestine and hatch eggs
- No CS
- Intermediate hosts : Sheep, goats, cattle, pigs, horses, deer, HUMAN, rodents
- Eat infective eggs released in the env. from definitive hosts
-
Larvae migrate aross intestinal wall, enter circulation to reach organs (++ lungs + liver) where they form cysts.
- E granulosus : cysts are thick-walled
- E multilocularis : cysts are multilocular (multiple chamber), thin-walled (alveolar)
- Endemic in South America, Africa, Asia, China.. ++ in rural populations that raise sheeps.
-
Dx E granulosus = fecal flott (high specific gravity)
- N.b. not distinguishable from Taenia eggs
-
Dx E multinodulari/s = ELISA or PCR
- Too tiny for fecal flott
- TREATMENT : praziquantel
- ZOONOTIC : humans are aberrant hosts. ++ by egg ingestion in food and water. causes large cystic lx in organs.

STRONGYLOIDES STERCORTALIS

- Transmission : SOIL or AUTO-infection, ++ in warm, wet and unsanitary conditions
- larvae in soil → migrate through skin -> to small intestine → lay eggs in SI → larvae hatched from the intestine into the env.
- Auto-infection : hatched larvae can RE-infect the host through skin around the anus!

- Dx : fecal flottation
- Tx : febantel, pyrantel pamoate, fenbendazole…
(whipworm)
