  10. what is the direct life cycle of the roundworm?
    1- adult roundworm in the small intestine

    2-eggs are passed in the feces

    3-egg turns into larvae in egg

    4-egg is ingested

    5-egg in stomach, and migrates through facia, abdomen up to the trachea causing irritation

    6-dog coughs up larvae and reswallows into the stomach where is now in an infective state

    7- incists in small intestine where more eggs are laid and excreated through feces
  11. what parasite does this egg belong too?
    roundworm
  12. what are the rots of roundworm?
    • Ingesting eggs or larvae (direct transmission)
    • found in contaminated soil or feces

    • (indirect transmission)- ingesting animal with round
    • worm
  13. what are treatment and control of roundworm?
    • -Oral de wormers:pyran, strongid T, lopatol,
    • Drontal, Drontal plus, pyr-a-pam, panacur, interceptor
  14. -good hygiene-including deworming
  15. -preventative products
    • -sentinel, revolution,
    • advantage multi, heartgard-30
  16. Main points of hookworms?
    -nematode group

    • Scientific name:

    2-eggs are passed in the feces

    3-turn into infective third stage larva in the enviroment

    4- are ingested or can migrate through pentrating the skin pads

    5-already infective do not need to be coughed and reswallowed.enter small intestine and infect by excreating more eggs
