Ancylostoma present in man, wild carnivores and pigs
Ancylostoma duodenale
Ancylostoma present in cats
A. tubaeoerme, A. brazilienze
Ancylostoma present in dogs and foxes
A. caninum - dogs and fox
A. brazilienze - dogs
Describe the general characteristics of hookworms based on body appearance, buccal capsule, and color.
- anterior end is bent ventrally appearing like as “hook”
- has buccal capsule w/c bears teeth at the margin
- grey or reddish
Uncinaria stenocephala final hosts & predilection site
dogs, cats, fox; small intestine
small hookworm of sheep and goats found in the jejunum and ileum
Bunostomum trigonocephalum
large hookworm of cattle affecting the duodenum worldwide
Bunostomum phlebotomum
known as the common hookworm of man which may also affect dogs and pigs’ small intestine
Necator americanus
hookworm of sheep and goats found in the duodenum
Gaigeria pachyscelis
Give the hookworm larvae that are associated with cutaneous larval migrans or creeping eruptions in man
Ancylostoma braziliense, A. caninum, A. tubaeforme, and U. stenocephala
Give the 5 genera of Family Ancylostomatidae
Ancylostoma
Uncinaria
Bunostomum
Necator
Gaigeria
Give the two species of hookworms without prenatal and lactogenic transmission
A. braziliense, A. duodenale
The L3 of these species stay dormant in skeletal muscles, and reactivated during the gestation which are passed on the milk, causing anemia in puppies 2-3 weeks old
Ancylostoma caninum
known to be prolific egg layers
Ancylostoma caninum
Cutaneous larval migrans are caused by many larvae of hookworms, but commonly caused by which spp
Ancylostoma braziliense, A. caninum, A. ceylanicum
these parasites are not voracious blood suckers but hypoalbuminemia and low grade anemia may occur
Uncinaria stenocephala
The hookworm of pigs
Globocephalus samoensis
What is the predilection site and final hosts of these spp resembling A. caninum except without pulmonary route
dogs, cat, fox; small intestine (Uncinaria stenocephala
Give 1 clinical sign of Uncinaria stenocephala infection
pedal dermatitis
these hookworms affect cattles and buffaloes’ large and small intestines
Agriostomum vryburgi
Its pathogenesis includes foot stamping and one of the clinical signs is severe edema of intermandibular region
Bunostomum spp
Name the hookworm in which just 24 adult worms is sufficient to cause death due to the marked blood sucking ability
Gaigeria pachyscelis
Mode of transmission of Ancylostoma
Per os, Per cutis, Transmammary
Mode of transmission of Uncinaria
Peroral, ingestion of paratenic hosts
