Summary Background In Africa, the risk of mother-to-child transmission of HIV-1 infection is
high. Short-course perinatal oral zidovudine might decrease the rate of transmission. We …

Combination therapy with protease (PR) and reverse transcriptase (RT) inhibitors can
efficiently suppress human immunodeficiency virus (HIV) replication, but the emergence of …

ABSTRACT G-to-A hypermutation has been sporadically observed in human
immunodeficiency virus type 1 (HIV-1) proviral sequences from patient peripheral blood …

In this study, we describe two cases of human immunodeficiency virus type 1 (HIV-1)
intersubtype superinfection with CRF01_AE and subtype B strains, which occurred in two …

During the past year, a number of reports have described HIV-1 superinfection in human
subjects, defined as the reinfection of an individual with a second heterologous strain of HIV …

The perspective for the development of anti-HIV/AIDS vaccines became a target sought by
several research groups and pharmaceutical companies. However, the complex virus …

Background Advances in cloning and sequencing technology are yielding a massive
number of viral genomes. The classification and annotation of these genomes constitute …

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 …

Protease sequences from HIV-1 group M subtypes A–H reveal di... : AIDS Protease sequences
from HIV-1 group M subtypes A–H reveal distinct amino acid mutation patterns associated with …

Recombination is an important way to generate genetic diversity. Accumulation of HIV-1 full-
length genomes in databases demonstrated that recombination is pervasive in viral strains …
