  1. how long can the toxocara canis (roundworms in dogs) ascarids get
    • females-greater then 20cm
    • males- around 10cm
  2. what is the route for tracheal migration
    • dog ingest egg
    • the larvae hatches
    • larva migrates to the lungs
    • climbs up the trachea
    • dog coughs it up than swallows to the GI tract
    • it matures to adult in intestine
  3. where would you find tracheal migration and what signs will you see
    • in pups less than 3 months
    • may see respiratory signs
  4. what is the route for somatic migration
    • eggs ingested and hatched
    • larvae migrates thru the tissues
    • encyst in tissue
  5. what happens if animal is prego with somatic migration
    • excyst late gestation
    • get to the pups thru placenta or milk
  6. where will you see somatic migration
    in pup older than 3 months
  7. habronema spp.
    • eqine nematode
    • stomach worm
    • most provelent in moist warm climates
    • intermitted host are flies
    • adults develop in the gastric mucosa
    • larvae in the feces and are ingested by magets who mature into flies, flies feed on horses lips and deposit the larvae that swallowed and matured
    • causes summer sores in horses
  8. how do oxyuris equi look
    • "pinworms"
    • white to gray in color
    • very┬ásmall
    • pointed tail
    • male- less than 12 mm
    • females- 75-150mm
  9. oxyuris equi
    • pinworms in horses
    • lift tail head and see it-tape test or flashlight at night
    • simple direct life cycle
    • tail head is irrated
    • females live in secum exit through the spinter, eggs drop off and land on ground or on the feed
  10. strongyles
    • elongated thin walled ova
    • contain morula-grape cluster appearance
    • seen in many species
    • many species are blood suckers- referred to as hookworms
    • small-12mm
    • large-38-47mm
  11. how are pinworms diagnosed
    with celephane tape
  12. blood in stool dark vs bright
    • dark is digested blood
    • bright comes from further down in the intestine, its ingested
  13. abbert migration
    • worse if it happens in a host it should be in
    • unnatural
    • may or may not hurt the animal
  14. strongyles large vs small which one is more pathogentic
    large one because it has a long and wondering life cycle
  15. prepatent period
    • the time before the inital infection and they start laying eggs or can be detected
    • going to see clinical signs but they haven't started laying eggs
    • ex)hookworms 12 days
  16. direct life cycle
    • does not require another
    • can reinfect that host again and again
    • does not have an immediate host
  17. indirect life cycle
    • requires another host in order for it to complete the cycle to become infective
    • involves an intermiediated host
    • ex) tapeworms comes from flies
    • heartworms come from mosquitos
  18. which is bigger roundworms tapeworms or whipe worms
  19. what are considered protozoa
    giardia and coccidia
  20. ectoparasites
    • parasites living on the host
    • examples) mites, ticks, fleas, myiasis producing flies
  21. endoparasites
    • internal parasites
    • parasites that live within the body and feed on the tissues or body fluids or compete directly with there food
    • examples) protozoa, trematode, tapeworms, nematodes
  22. whats is the diagnosis for an ectoparasite
    • skin scraping for mange mites
    • observe where fleas like to go like the tail
    • culture
    • tape test
  23. what is the diagnosis for an endoparasite
    • fecal
    • urine
    • blood
