RESUMO
In the Brazilian HIV-1 epidemic, subtypes B, C, and F1 are cocirculating in the population. Sequences of the partial pol gene from 463 HIV-1-infected patients were obtained from plasma samples and viral subtype was characterized. BF recombinants were found in 8% of the samples. Fifteen different patterns were observed. A CRF28_BF and CRF29_BF structure was found in 29.7% of the samples, CRF12_BF in 13.5%, and CRF39_BF in 2.7%. Two other patterns were identified in each of three samples. These findings could indicate a new CRF description, but to determine this a full length study is required.
