title: Intraspecific phylogenetics: support for dental transmission of human immunodeficiency virus.
abstract: A new method to estimate within-species gene genealogies was used to establish linkages among individuals associated with the Florida dental human immunodeficiency virus transmission case. Phylogenetic relationships were estimated from 103 nucleotide sequences from the V3 region of the env gene representing the Florida dentist, eight of his seropositive patients, and many local controls. The cladogram estimation procedure supports linkages among individuals within the previously described dental clade, whereas local controls and other patients form independent networks or are outliers in the main network, indicating more distant evolutionary relationships. A nested statistical analysis also indicates significant cohesion of the dental clade group.
