Bunostomum is a genus of nematodes of the small intestine of ruminants and camelids. Important species include B. phlebotomum in calves and B. trigonocephalum in lambs. The worms are stout and measure 1–3 centimetres (0.4–1.2 in) in length. Young animals are most commonly affected and only several hundred worms are necessary to cause morbidity. Adults often carry worms without showing clinical signs.

Life cycle
The life cycle is direct, with a prepatent period of 30–56 days. Eggs hatch on the ground and develop into infective larvae in several weeks. Larvae penetrate through the skin or are ingested and then migrate to the respiratory system, are coughed up and swallowed, and finally reach the small intestine. Eggs are then shed in the feces of the infected host.
