Physaloptera

A large genus of spiruroid roundworms parasitic in the stomach and duodenum of vertebrates, especially birds and mammals; they are transmitted via insect and annelid intermediate hosts and are frequently pathogenic, causing erosions and catarrhal gastritis. P. caucasica is a species reported in humans in the southern part of the USSR; P. mordens is a species from tropical Africa found only rarely in the esophagus, stomach, and intestine of humans (probably cases of temporary infection from ingestion of infected insects). [G. physallis, bladder, + pteron, wing]
