title: Detection of nucleic acids homologous to human immunodeficiency virus in wastewater.
abstract: Raw wastewaters were obtained from the cities of Belle Glade, Ocala and Gainesville in the state of Florida and were concentrated using several established methods for the recovery of human enteroviruses. The nucleic acids were then extracted from the wastewater concentrates, suspended in 2 x SSC with and without 2 N NaOH (for the detection of DNA and both DNA and RNA, respectively), and dot blotted onto hybridization membranes. These membranes were then hybridized with three 32P-end-labeled 18-mer oligonucleotides directed against the LTR, gag, and env regions of the human immunodeficiency virus type 1 (HIV-1). Autoradiographic analyses of these blots indicate that sequences homologous to HIV-1 genomic RNA and proviral DNA were found in Belle Glade wastewater but not in wastewater from Ocala and Gainesville. These findings may have implications in the wastewater treatment system as well as for detection of HIV-1 in clinical samples.
