Background: The main cause of virological failure during AIDS treatment is the resistance to
antiretroviral medications (ARV). Aim: To search for mutations associated with ARV …

BACKGROUND: Infections with drug-resistant HIV viruses in naïve subjects may cause
antiretroviral (ARV) treatment failure. The prevalence of ARV resistance mutations in HIV-1 …

The transmission of drug-resistant HIV-1 strains might compromise the efficacy of current first-
line antiretroviral (ARV) regimens. Between 2004 and 2008, HIV-1 reverse transcriptase …

We report the first study on prevalence of antiretroviral drug-associated resistance mutations
in Venezuela. Protease and reverse transcriptase (RT) coding regions were analyzed in …

Transmission of drug-resistant HIV (TDR) has been associated with virologic failure of “first-
line,” nonnucleoside reverse transcriptase inhibitor (NNRTI)-based antiretroviral therapy …

BACKGROUND: Systematically obtained data on antiretroviral (ARV) resistance in
Colombia are lacking. Local estimates of resistance are needed to guide testing, therapy …

The main objective of this study is to evaluate the prevalence of resistance-associated
mutations to reverse transcriptase (RT) and protease (PR) inhibitors (I) 2 years after the …

BACKGROUND: Most studies on antiretroviral (ARV) resistance of human immunodeficiency
virus (HIV) have been done on subtype B which only represent a limited proportion of …
