Which helminth causes infection in AIDS?
Disseminated infection caused by S. stercoralis is seen in AIDS.
a. Disseminated strongyloidiasis involves widespread dissemination of larvae to extraintestinal organs (eg, CNS, heart, urinary tract, endocrine organs), which are outside the realm of the parasite's ordinary life cycle. All organs and tissues may be invaded, along with the small intestine.
b. In these severe forms, translocation of enteric bacteria may occur, leading to polymicrobial bacteremia and occasionally meningitis with enteric pathogens.
c. The enteric pathogens may be carried on the filariform larvae or may enter the circulation through intestinal ulcers.
