| high genetic diversity of human immunodeficiency virus type 1 in angola. | to investigate which hiv-1 genetic forms are circulating in angola, we have determined the gag and/or env genotypes of 48 isolates from patients living in cabinda and luanda provinces. the following subtypes were identified: a1 (18 samples, 38%), c (7, 15%), h (5, 10%), j (3, 6%), g (2, 4%), a2 (2, 4%), f1 (1, 2%), and d (1, 2%). the env gene fragment was untypable in one sample. discordant subtype classifications in the gag and env genes were found in eight (17%) samples. there were six differe ... | 2005 | 15943573 |
| highly divergent subtypes and new recombinant forms prevail in the hiv/aids epidemic in angola: new insights into the origins of the aids pandemic. | angola, located in south-western africa, has a remarkably low hiv/aids prevalence in the adult population (3.7%). it is bordered in the north by the democratic republic of congo (drc) and republic of congo that are at the origin of human hiv-1 infections. it is, therefore, likely that hiv-1 strains circulating in angola are genetically diverse and representative of the origin of the hiv/aids epidemic. the aim of this work was to investigate in detail the genetic diversity and molecular epidemiol ... | 2009 | 18562253 |
