title: Nematode larvae (Spirurida: Physalopteridae) causing infarction of the bowel in an infant.
abstract: A case is reported of an 11-month-old baby suffering from gangrene of the distal portion of the small bowel due to infestation by larval worms belonging to the order Spirurida, family Physalopteridae and probably the genus Physaloptera. Microscopically, the resected bowel showed ischaemic necrosis, eosinophilic granulomata and larval worms in the lumen and wall of blood vessels. The inflammatory process extended into the mesentery, where the vessels showed focal necroses, thrombosis and endarteritis. Infection in this child in the Queensland countryside is considered to have resulted from ingestion of insects on grass eaten when at play, the grass having been contaminated by bandicoots.
