Molecular Epidemiology of HIV-1 in Afghanistan, Iran, and Pakistan
We conducted this study to obtain a comprehensive picture of molecular epidemiology of HIV-1 in three neighboring countries, i.e. Afghanistan, Iran, and Pakistan as a basis for discussing possible hypothesis regarding between-country virus transmission. Our results showed that subtype composition differs between these countries with more variation in Pakistan than Iran and Afghanistan. The CRF3...
متن کاملComprehensive Characterization of HIV-1 Molecular Epidemiology and Demographic History in the Brazilian Region Most Heavily Affected by AIDS.
UNLABELLED The high incidence of AIDS cases and the dominance of HIV-1 subtype C infections are two features that distinguish the HIV-1 epidemic in the two southernmost Brazilian states (Rio Grande do Sul [RS] and Santa Catarina [SC]) from the epidemic in other parts of the country. Nevertheless, previous studies on HIV molecular epidemiology were conducted mainly in capital cities, and a more ...
متن کاملGenetic and biologic characterization of HIV type 1 subtype C isolates from south Brazil.
The molecular and biological properties of HIV-1 subtype C strains from South Brazil were investigated. We sequenced gag and env fragments of viruses from 22 HIV-1-infected individuals from Porto Alegre City, which has the highest frequency of subtype C in the country. The sequences were then compared with other subtype B, C, and F strains isolated in Brazil and other countries using phylogenet...
متن کاملHIV genetic diversity in Cameroon: possible public health importance.
To monitor the evolving molecular epidemiology and genetic diversity of HIV in a country where many distinct strains cocirculate, we performed genetic analyses on sequences from 75 HIV-1-infected Cameroonians: 74 were group M and 1 was group O. Of the group M sequences, 74 were classified into the following env gp41 subtypes or recombinant forms: CRF02 (n = 54), CRF09 (n = 2), CRF13 (n = 2), A ...
متن کاملPhylogenetic analysis of protease and transmembrane region of HIV type 1 group O.
The molecular diversity and phylogenetic relationship of 22 HIV-1 group O strains were examined on the basis of the protease gene and the N-terminal region of gp41env. Analysis of the newly characterized protease sequences with 12 reference sequences revealed no specific clustering patterns, despite the distinct geographic locations of the specimens. In contrast, analysis of the newly sequenced...
