A hookworm species that infests the intestinal walls of dogs and the primary cause of ancylostomiasis in dogs


Ancylostoma caninum is a hookworm species belonging to the genus Ancylostoma of the family Ancylostomatidae. One of its distinctive features is the three pairs of teeth in contrast to Ancylostoma duodenale (human hookworm) and Ancylostoma braziliense (cat and dog hookworm) in having only two pairs of teeth on their buccal cavity.1 Nevertheless, similar to other species of hookworms, the adult forms are found attached on the intestinal wall through their mouth and then feed on blood. Thus, one of the symptoms associated with these hookworms is iron deficiency anaemia. Infestation with Ancylostoma is referred to as ancylostomiasis. A. caninum infestation of dogs can lead to the death of the host although not all dogs die from it and may be asymptomatic. Apart from dogs, this hookworm species also takes wolves, foxes, cats, and other carnivores as their hosts. It has also been reported in humans.2 It is common in Sri Lanka, Malaysia, and southeast Asia.
