Block 1 Lecture ?'s Flashcards
parasite definition
organism that is metabolically dependent and survives at the measurable expense of another organism
how do parasites cause disease in their host?
they feed on host resources and impact the host physically and immunologically
how is paratenic host different from intermediate host
host where the larval parasite does not undergo any development
a 12 week old puppy presents with pot bellied appearance, and hair coat w/ dried vomit and diarrhea . A presumptive diagnosis of toxocara canis is made. How does this parasite cause disease
mechanical damage in the lungs leads to pneumonia, irritation in the gut leads to ADR, vomiting and diarrhea
why are clinical signs associated with Trichuris infection in dogs often referred to as “psuedo-addison’s disease”
both diseases are characterized by electrolyte imbalance w/ low sodium/ potassium ratio
a puppy presents with cough and diarrhea. Lab work supports a diagnosis of Strongyloides. How does the lifecycle biology facilitate production of significant disease
parasitic females accumulate significant worm burdens by autoinfection
what label is used to describe the clinical condition affecting the eye
ocular larval margins
