Tential impact of HIV-1 diversity on both vaccine development and the sustainability of antiretroviral therapies, it is particularly important that molecular epidemiological surveillance is continued in HIV diversity hotspots such as Cameroon. In this study we have focused on characterizing the diversity of gag and nef genes of Cameroonian HIV-1 isolates. These genes are?2013 Tongo et al.; license

Cias Zembe1, Eitel Mpoudi-Ngole2, Carolyn Williamson1,4 and Wendy A Burgers1*AbstractBackground: Cameroon, in west central Africa, has an extraordinary degree of HIV diversity, presenting a major challenge for the development of an effective HIV vaccine. Given the continuing need to closely monitor the emergence of new HIV variants in the country, we analyzed HIV-1 genetic diversity in 59 plasma s
