Ancylostoma braziliense

Definition

noun

A hookworm species that infest the intestinal walls of cats and dogs, but may incidentally infest the skin of humans and cause cutaneous larva migrans


Supplement

Ancylostoma braziliense is a hookworm species belonging to the genus Ancylostoma of the family Ancylostomatidae. Similar to another Ancylostoma sp. (i.e. A. duodenale, hookworm of humans), Ancylostoma braziliense has two pairs of teeth on its buccal cavity. It is common in Brazil, Africa, India, Sri Lanka, Indonesia, and Philippines.1

This parasite feeds on blood as it attaches itself on the intestinal wall of the definitive host, i.e. a cat or a dog. The presence of this hookworm is associated with iron deficiency anaemia and may be fatal particularly to young cats and dogs. Infestation with Ancylostoma is referred to as ancylostomiasis. Apart from dogs and cats, this hookworm may infest humans. However, humans are not the definitive host but incidental host of A. braziliense. This hookworm is unable to fully penetrate the skin of humans and therefore creeps through the skin and creates tunnels underneath the skin. This condition is referred to as cutaneous larva migrans. This condition is itchy and a common skin infection in tropical regions. Humans may pick up this hookworm by walking barefoot in sandy beaches or any moist areas contaminated with A. braziliense infective larvae.
