For many years, intestinal infections caused by opportunistic organisms have represented a major problem in immunocompromised patients with AIDS. In Western countries, a decreased incidence of parasitic intestinal infections has been registered over the last years, mainly as a result of immunological reconstitution in patients receiving highly active antiretroviral therapy (HAART) [1]. Even in the HAART era, however, diarrhea is still an occurring symptom in human immunodeficiency virus (HIV-infected individuals [2, 3], and 2.8% of 15,000 HIV patients hospitalized with a diarrheal illness in New York City in 1998 harbored intestinal pathogens [4]. The antiparasitic effect of HAART is indirect and not always associated with eradication. Indeed, relapsing intestinal parasitoses are commonly reported in patients with decreased CD4 cell counts following virological HAART failure or discontinuation of treatment [5, 6].
