Most commercial HIV-1 genotyping assays are hampered by high cost in resource-limited settings. Moreover, their performance might be influenced over time by HIV genetic heterogeneity and evolution. An in-house genotyping protocol was developed, and its sequencing performance and reproducibility were compared to that of ViroSeq™. One hundred ninety plasma(More)
HIV-1 CRF02_AG accounts for >50% of infected individuals in Cameroon. CRF02_AG prevalence has been increasing both in Africa and Europe, particularly in Italy because of migrations from the sub-Saharan region. This study investigated the molecular epidemiology of CRF02_AG in Cameroon by employing Bayesian phylodynamics and analyzed the relationship between(More)
Currently the prevalence of HIV-1 infection in Cameroon is 5.1%, CRF02_AG subtype is responsible for about 50% of infections. Since an HIV-1 drug resistance test is not yet available widely, accurate data on the prevalence of resistant viral strains are missing. The objective of this study was to determine HIV-1 genetic diversity and to characterize HIV-1(More)
BACKGROUND HIV infection has commonly been found to affect lipid profile and antioxidant defense. OBJECTIVES To determine the effects of Human Immunodeficiency Virus (HIV) infection and viral subtype on patient's cholesterol and oxidative stress markers, and determine whether in the absence of Highly Active Antiretroviral Therapy (HAART), these(More)
HIV-1 subtype G has played an early and central role in the emergent complexity of the HIV-1 group M (HIV-1M) epidemic in central/west Africa. Here, we analysed new subtype G env sequences sampled from 8 individuals in Yaoundé, Cameroon during 2007-2010, together with all publically available subtype G-attributed full-length env sequences with known(More)
With ongoing earlier enrollment on and rapid scale-up of antiretroviral therapy (ART) in Cameroon, there are increasing risks of transmitted HIV drug resistance (HIVDR) at population levels. We, therefore, evaluated the threshold of HIVDR in a population initiating ART, to inform on the effectiveness of first-line regimens, considering HIV-1 diversity,(More)
BACKGROUND Scale-up of antiretroviral therapy (ART) and the growing number of long-term treated patients may favor multi-HIV drug resistance (HIVDR) in resource-limited settings. Understanding the burden of HIVDR with ART-exposure may provide new insights for an effective long-term management of infected patients. METHODS Sixty-six HIV-infected(More)
A broad and rapidly changing HIV Type 1 (HIV-1) diversity has been reported from different populations in Cameroon since the early epidemic. Our understanding of HIV-1 dynamics can be improved by a systematic surveillance in Cameroon as accessibility and use of antiretroviral drugs increase. To contribute to this, we genotyped 30 samples by sequencing the(More)
