  • Notice how long this list is! Chances are all of us fall in one or more categories of at-risk people!
  • Southest pervalence = 38.5% for hookworms and 17.7% for roundworms Trichuris vulpis is the whipworm and it’s prevalence is high but we will not discuss it today because it does not pose a significant zoonotic risk.
  • Eggs passed in feces and hatch on ground in 16-20 hours  in 2-8 days the motile infective larvae may live in soil or plants  larvae are either ingested or penetrate through the skin  dam may pass larvae to nursing puppies (through milk) or through placental blood supply  in 2-3 weeks the larvae have matured and can produce eggs (when ingested) and in a month the larvae can produce eggs if penetrated by skin Eggs thrive better in moist, well-aerated soil with indirect sun light. Ancylostoma eggs are setroyed by freezing, whereas Uncinaria eggs are more resistant to cold.
  • Nursing puppies or through placental blood supply
  • Blood loss – they have powerful hooks that allow them to latch to the intestinal wall and suck blood; large worm loads can suck enough blood to lead to anemia
  • These are diagrams published by the CDC concerning hookworm infections in humans . This goes to show the zoonotic importance of this disease and the need to raise awareness.
  • Cutaneous larva migrans infections can be very itchy in humans
  • Monthly = every 30 days! Feel free to ask your veterinarian what fecal test technique he/she uses to diagnose intestinal parasites and let him/her know that you know that centrifugal flotation technique is the gold standard

    • Everybody, especially children and immune compromised people
    • Pet owners, people working with animals (veterinarians, veterinary technicians, shelter workers, etc.), electricians, plumbers, exterminators, farmers, gardeners, sunbathers and children who play in contaminated areas are at high risk
  • 8.
    • Intestinal parasites are virtually everywhere in the environment, and can survive in the soil for years in cold or warm climates.
    • In a recent study, 10-30% of public soil samples were contaminated with intestinal parasite eggs.
    • A national survey of shelters revealed that almost 36% of dogs nationwide and 52% of dogs from the southeastern states harbored parasites capable of causing human diseases.
  • 9.
    • In the U.S. alone, an estimated 10,000 cases of roundworm infections occur each year.
    • Hookworms are the second most common worm infections in humans (after roundworms).
    • Fleas can cause diseases in humans.
    Roundworms Hookworms Fleas

    • The southeastern states have the highest rates of infection of cutaneous larva migrans.
    • Electrician, plumbers, exterminators, farmers, gardeners, sunbathers and children who play in contaminated areas are
    • at high risk

  • 18.
    • Companion Animal Parasites Council(CAPC) principles include:
    • Giving heartworm prevention monthly
    • Deworming monthly (hookworms/roundworms)
    • Appling flea and/or tick control monthly
    • Performing fecal examinations*:
    • a. 2 to 4 times during the first year of life
    • b. 1 to 2 times a year in adult pets
    • * Centrifugal flotation technique
