Abstract
To examine the genetic and antigenic characteristics of HIV-1 in Indonesia, samples from 19 HIV-positive volunteers were studied. By a combination of PCR typing and DNA sequence analysis, 12 of the 19 volunteers were determined to be infected with HIV-1 clade B and seven with clade E. Six of the seven Indonesian clade E isolates were from volunteers associated with the Indonesian Military during a peacekeeping mission in Cambodia. Infectivity reduction neutralization assays showed that the Indonesian E viruses were effectively neutralized by Thailand clade E HIV-1 antisera but not by U.S. clade B antisera. The Indonesian clade B virus tested was neutralized by U.S. clade B antisera and not by the Thailand E antisera. Using a previously described serologic typing ELISA based on clade B and E V3 peptides, genetic clade was accurately determined in eight of eight sera tested. This is the first report of the genetic and antigenic analysis of HIV-1 isolates from Indonesia. The data indicate that at least two genetic and antigenic HIV-1 clades (clade E and B) circulate in Indonesia.
