Due to the advent of AIDS, there is currently great interest in opportunistic infections in people with compromised immune systems. This special volume of Advances in Parasitology provides a detailed account ofthe pathogens associated with human enteric diseases, Cryptosporidium parvum, Enterocytozoon bieneusi and Cyclospora cayetanensis. This volume is essential for all parasitologists working on opportunistic protozoa.
