Synopsis

CAPC Recommends CAPC recommends testing all dogs for hookworms by fecal flotation with centrifugation . Fecal tests for specific parasite antigens or PCR, which detects parasite DNA, are useful in identification of hookworms where few to no eggs and few adult worms are present, an infection with only young worms, or with single sex infections.

Species

Feline Ancylostoma tubaeforme Ancylostoma braziliense Uncinaria stenocephala (rare in cats in the United States)

Disease

All hookworms suck blood, but A. caninum is a voracious bloodsucker and can actually bleed a puppy to death. Disease in dogs caused by infection with A. caninum is most severe in young pups that are infected through nursing (the transmammary route) shortly after birth.

Prevalence

Ancylostoma caninum is a common parasite of dogs throughout the United States and are found in most tropical and subtropical environments. Both young and adult canine and feline hosts can harbor hookworms and pass eggs in their feces.

Treatment

In severely affected animals, anthelmintic treatment must be combined with supportive therapy to keep the animal alive until the drugs can kill the worms. In addition to keeping the patient warm, supportive treatment can include electrolyte and fluid therapy, iron supplements, a high-protein diet, and when clinically indicated, blood transfusions.

Control and Prevention

Puppies require more frequent anthelmintic administration than adult dogs because (1) they often are serially reinfected via nursing and from the environment and (2) they often harbor migrating parasite larvae that later mature and commence laying eggs. Hookworm infections in puppies may cause serious illness or even death before a diagnosis is possible by fecal examination.

Public Health Considerations

Animal hookworms are well-documented zoonotic disease agents and are the most common cause of cutaneous larva migrans (CLM) in people. The larvae migrate in the skin, producing intensely pruritic, serpentine lesions.
