Phylogenetic analysis of pol sequences derived from pregnant women infected with HIV-1. Trees were constructed by using the neighbor-joining method as described in Patients and Methods. A transition/transversion ratio of 2 was used and 1,000 bootstrap resamplings were performed. Left panel: Subgrouping with clade B HIV-1. Right panel: Grouping with non-B HIV. Reference sequences (REF) were obtained from the Los Alamos National Laboratory database (2001) (8). The scale bar represents 0.02 nucleot

Figure. . Phylogenetic analysis of pol sequences derived from pregnant women infected with HIV-1. Trees were constructed by using the neighbor-joining method as described in Patients and Methods. A transition/transversion ratio of 2 was used and 1,000 bootstrap resamplings were performed. Left panel: Subgrouping with clade B HIV-1. Right panel: Grouping with non-B HIV. Reference sequences (REF) were obtained from the Los Alamos National Laboratory database (2001) (8). The scale bar represents 0.02 nucleotide substitutions per site. Letter codes indicate country of origin. All nucleotide sequence information was submitted to GenBank (accession no. DQ059647–DQ059749). CRF, circulating recombinant form.
