title: Phylogenetic analysis of HIV sequences obtained in a respondent-driven sampling study of men who have sex with men.
abstract: The presence of transmission clusters and their relationship to the recruitment chain were investigated in an HIV prevalence assessment survey using respondent-driven sampling among men who had sex with men (MSM) in Zagreb, Croatia. HIV infection was found in 18 of 360 participants. Five individuals belong to a transmission cluster of MSM infected with phylogenetically related HIV. All were recruited in later waves (fourth to ninth), suggesting that the population is sexually networked.
