Hookworms are intestinal, blood-feeding, parasitic roundworms that cause types of infection known as helminthiases. Hookworm infection is found in many parts of the world, [ 1 ] and is common in areas with poor access to adequate water, sanitation, and hygiene.
Canine and feline hookworms rarely develop to adulthood in humans. Ancylostoma caninum , the common dog hookworm, occasionally develops into an adult to cause eosinophilic enteritis in people, but their invasive larvae can cause an itchy rash called cutaneous larva migrans .
Zoonoses can be caused by a range of disease pathogens such as emergent viruses, bacteria, fungi and parasites; of 1,415 pathogens known to infect humans, 61% were zoonotic. [11] Most human diseases originated in non-humans; however, only diseases that routinely involve non-human to human transmission, such as rabies, are considered direct ...
Uncinaria stenocephala is a nematode that parasitizes dogs, cats, and foxes as well as humans. It is rare to find in cats in the United States. Uncinaria stenocephala is the most common canine hookworm in cooler regions, such as Canada and the northern regions of the US, where it can be found primarily in foxes (40%). [1]
Ticks and lice form another large group of invertebrate vectors. The bacterium Borrelia burgdorferi, which causes Lyme Disease, is transmitted by ticks and members of the bacterial genus Rickettsia are transmitted by lice. For example, the human body louse transmits the bacterium Rickettsia prowazekii which causes epidemic typhus.
Ancylostoma caninum is a species of nematode known as a hookworm, which principally infects the small intestine of dogs. [1] [2] [3] The result of A. caninum infection ranges from asymptomatic cases to death of the dog; better nourishment, increasing age, prior A. caninum exposure, or vaccination are all linked to improved survival.
Humans are false hosts for the canine roundworm Toxocara canis and the canine hookworm (Ancylostoma caninum), i.e. the larvae damage infected organs but do not develop into adult worms. Both are the most important zoonotic agents among canine nematodes in Central Europe. Toxocara larva in the liver of a human being
Rabies (hydrophobia) is a fatal viral disease that can affect any mammal, although the close relationship of dogs with humans makes canine rabies a zoonotic concern. Vaccination of dogs for rabies is commonly required by law. Please see the article dog health for information on this disease in dogs. [1]
