Tx: Definitive host (human) - Niclosamide
Intermediate host (swine) - rely on control measures Cx: Restrict human defecation in swine pastures, restrict human from eating raw pork, USDA condemnation of "measly pork" |
|
|
What is the pathology for Echinococcus granulosus
|
Definitive host (dog) - No pathology
Intermediate host (Sheep, ruminants, swine, man) - Unilocular cyst - pressure atrophy of adjacent organs, risk of anaphylactic reaction |
|
|

|
Definitive host (dog) - No pathology
Intermediate host (Rodents, cattle, horses, man) - Multilocular cyst - pressure atrophy of adjacent organs, risk of anaphylactic reaction, infiltrates through surrounding tissue like a tumor |
|
|
|

|
|
|
|

|
|
|
|
