Parasites and malabsorption.

In summary, it appears that giardiasis, coccidiosis, cryptosporidiosis, strongyloidiasis, capillariasis and perhaps P. falciparum malaria are the only parasitic diseases which cause malabsorption of many nutrients. D. latum and A. lumbricoides interfere with vitamin B12 and vitamin A absorption, respectively. In view of the increasing use of immunosuppressive therapy, it is likely that malabsorption caused by intestinal parasites may become even more evident in the future.
