AIDS is caused by two lentiviruses: HIV-1 and HIV-2 [1, 2]. AIDS was first recognized in the
1980s and is presently the leading cause of death in developing countries. Globally, it is …

Publisher Summary This chapter focuses on the effects of human immunodeficiency viruses
in the developing world. Acquired immunodeficiency syndrome (AIDS) has become a major …

The diploid nature of human immunodeficiency virus type 1 (HIV-1) indicates that
recombination serves a central function in virus replication and evolution. Previously, while …

Continual human immunodeficiency virus type 1 (HIV-1) evolution and expansion within the
human population have led to unequal distribution of HIV-1 group M subtypes. In particular …

Background. Many different subtypes of human immunodeficiency virus (HIV) type 1 have
been identified, particularly in sub-Saharan Africa. However, much remains unknown …

Objective: To determine whether different HIV-1 genotypes present in a single cohort, in Dar
es Salaam, Tanzania, showed differences in timing for transmission from mothers to their …

One of the major characteristics of the human immunodeficiency viruses (HIVs) is their
extremely high genetic variability. This extensive heterogeneity is the result of the high error …

To better understand the virological aspect of the expanding AIDS epidemic in southern
Africa, a set of 23 near-full-length clones of human immunodeficiency virus type 1 (HIV-1) …

Objective: To characterize the subtype C strains of HIV type 1 that circulate in Brazil,
especially those originated from the southern part of the country. Design and methods: One …

Genetic recombination increases diversity in HIV-1 populations, thereby allowing variants to
escape from host immunity or antiviral therapies. In addition to the currently described nine …
