 AB    Human immunodeficiency virus type 1 (HIV-1) isolates recovered from
       infected children in Romania were characterized for their biologic,
       serologic, and molecular properties. The isolates were from subjects in
       different clinical states, and all showed cytopathic properties in
       peripheral blood mononuclear cells and varying kinetics of replication.
       The isolates grew to varying titers in macrophages and established T
       cell lines. Serologic evaluation with Romanian sera indicated stronger
       antibody response to the gp120 of Romanian isolates than to the envelope
       protein of HIV-1 isolates from other countries. Although there was
       cross-neutralization among the Romanian isolates, no substantial
       activity was noted against HIV-1 prototype strains from the United
       States, Africa, and Thailand. Genetic analysis of the envelope C2-V3
       region strongly suggests that the Romanian isolates are a subtype
       distinct from those assigned to other HIV-1 strains analyzed to date.
       This finding raises questions about the origin of HIV-1 in Romania.
