OBJECTIVE This cross-sectional study was to determine the prevalence and characterization of high-risk HPV genotypes circulating among adolescents in Ouagadougou. METHODS From September to December 2013, 200 adolescents recruited from a youth counseling center have voluntarily accepted a swab of the endocervical canal. The identification of the genotypes(More)
This research highlights the chemical composition, antioxidant, anti-inflammatory and anti-proliferative activities of essential oils from leaves of Ocimum basilicum, Ocimum americanum, Hyptis spicigera, Lippia multiflora, Ageratum conyzoides, Eucalyptus camaldulensis and Zingiber officinale. Essential oils were analyzed by gas chromatography-mass(More)
The development of cervical cancer is associated with high-risk Human papilloma viruses (HPV-HR). In sub-Saharan Africa cervical cancer is the most common cancer among women and the leading cause of death attributed to malignant tumors. This study aims to identify HPV genotypes within the 30'S and 50'S HPV families found in two previous studies from our(More)
The careHPV and HC2 assays were compared for high-risk human papillomavirus (HR-HPV) DNA detection in cervical samples from 149 HIV-1-infected African women. The HR-HPV DNA detection rates were 37.6% and 34.9% for careHPV and HC2, respectively. Agreement between the two tests was 94.6% (95% confidence interval [CI], 89.7% to 97.7%) with a kappa value of(More)
OBJECTIVE To study the involvement of variations in 4 genes associated with susceptibility and/or protection against HIV-1 in serodiscordant couples in Burkina Faso, namely, genes encoding HLA-B57, interferon regulatory factor 1 (IRF1), dendritic cell-specific ICAM3-grabbing nonintegrin (DC-SIGN) and CCR5 delta 32 (CCR5Δ32). METHODS Two DC-SIGN and two(More)
Introduction: L'infection par Helicobacter pylori constitue un problème de santé publique notamment dans les pays en développement. Elle entraine une gastrite pouvant évoluer vers des formes sévères d'ulcération et de transformation maligne. La présenté étude avait pour objectif de diagnostiquer H. pylori par des techniques sérologique et moléculaire au(More)
BACKGROUND AND OBJECTIVE Cervical cancer usually occurs several years after persistent infection with oncogenic or high-risk human papillomavirus. The objective of this study was to determine carriage of 14 genotypes of high-risk human papillomavirus among women at Orodara and then characterize the genotypes found in these women. MATERIALS AND METHODS(More)
Epstein Barr Virus (EBV) and Human Herpes Virus 6 (HHV-6) are responsible for severe diseases, particularly in immunocompromised persons. There is limited data of the infection of these opportunistic viruses in Burkina Faso. The purpose of this study was to characterize EBV and HHV-6 subtypes and to assess their impact on CD4 T cell count, HIV-1 viral load(More)
Human papilloma virus (HPV) infection remains a worldwide concern, especially in Sub-Saharan Africa where cervical cancer is the leading cause of cancer death in women. The aim of the study was to determine the prevalence and genotypic distribution of High-Risk HPV (HR-HPV) involved in Cervical Intraepithelial Neoplasia (CIN) II and III and in cervical(More)
