Heading


ID#:1517
Description:Under a magnification of 128X, this photomicrograph reveals ultrastructural details displayed a parasitic nematode (roundworm), Strongyloides stercoralis, which was in its filariform larval stage of development.
Though frequently asymptomatic when present, clinical features of a strongyloidiasis infection include gastrointestinal symptoms such as abdominal pain and diarrhea. Pulmonary symptoms (including Loeffler’s syndrome) can occur during pulmonary migration of the filariform larvae. Dermatologic manifestations include urticarial rashes in the buttocks and waist areas. Disseminated strongyloidiasis occurs in immunosuppressed patients, can present with abdominal pain, distension, shock, pulmonary and neurologic complications and septicemia, and is potentially fatal. Blood eosinophilia is generally present during the acute and chronic stages, but may be absent with dissemination.
