"Does my meat make me look bad?"
eggs usually require how much time in environment to become infective?
ingestion of infective egg or paratenic host (larvae encysted in rabbits)
Baylisascaris procyonis (raccoons) causes what disease in us?
NEURAL larval migrans
Hookworms (T. canis) cause what in us after how long in the environment?
- cutaneous larval migrans
- 5-10 days (because a short time after you visit a hooker and you go to base L3, your skin starts crawling....)
-L3 penetrates human skin
Trichinellosis - Larvae in cyst of swine, bears, wildcats, rodents. Infect via what?
Ingestion! Eat em up! It's a trich! They hide in yummy meat, and then get you sick!
Echinococcus - Ingest the _______ in soil, water or food contaminated with with fecal matter. Definitive hosts are ______s
Dipylidium Caninum - ______tapeworm, humans become infected by _________ _________
ingesting the flea
Taeniasis - _______s are the definitive host infected by ingesting ________ from cattle (saginata) or swine (solium); or by eating undercooked pork or beef
(Taenia Tim, a human, encysted on being strong and eating that whole Christmas meat RAW)
Cysticercosis - humans get it by ingestion of the eggs of this AOD that were passed by people
Diphyllobothrium latum (_____Tapeworm ) - ________s are definitive host. Infected by.....
ingesting raw or under-cooked fish meat!
fish live in the bothrium (bottom) of the sea! and there are a "lat" of "um"
We are accidental hosts for Toxocara Canis/Cati.....what can they cause in us? (3)
Ocular larval migrans (unilateral in children)
Visceral larval migrans
Neural Larval migrans
What parasite causes Cutaneous Larval Migrans "Creeping Eruption"?

Cute hooker..... (cutaneous....hookworm)
Also, I think an"sickle"ostoma...a sickle is shaped like a hookworm
Heartworm in humans?
Zoonotic parasite that causes: >Edema of upper eyelids via Encystment in striated muscle
Trichinellosis (trichinella spiralis) (because that trich was so good that you could have had your eyes closed and would have been in the same boat for figuring it all out!!)
Zoonotic parasite that casues Alveolar & Cystic Hydatid disease
-E. Granulosus → Cystic Hydatid disease (develop cysts in the liver too!)
-E. Multilocularis → Alveolar Hydatid disease (larvae cause invasive, malignancy-like liver mass)
AOD that causes the following in humans
-Neurocysticercosis: cyst in brain or spinal cord; headache, seizure, stroke, death
-Cysticercosis: cyst in muscle; asymptomatic, lumps under skin

Deworm puppies at 2, 4, 6, 8 weeks, then monthly after that
-Treat regard/less of fecal exam results
-Treat dam at same time
