ABSTRACT
The acquired immunodeficiency syndrome (AIDS) is the end-stage of a progressive infection of the human host’s cellular immune system, in particular the T-helper (CD4 ) lymphocytes, by the human immunodeficiency virus type 1 (HIV-1). Though the closely related HIV-2 may also cause immunodeficiency and thereby give rise to opportunistic parasitic infections, HIV-related parasites in the following section will focus on those affecting HIV-1 infected individuals.
