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
