title: Typing of herpes simplex virus isolates with monoclonal antibodies and by nucleic acid spot hybridization.
abstract: Fifty-one clinical isolates of herpes simplex virus (HSV) were typed by an enzyme immunoassay (EIA) using mouse monoclonal antibodies, by DNA spot hybridization, and by restriction enzyme analysis using restriction endonuclease Eco RI. Extracts of VERO cells infected with the isolates were used for coating microtitre plates or denatured and spotted onto nitrocellulose filters. Viral antigens passively adsorbed to microtitre plates were detected by an indirect EIA using mouse monoclonal antibodies specific for HSV type 1 (HSV-1) or HSV type 2 (HSV-2). Spotted DNA was hybridized with 32P-labeled probes containing Hind III/Sal I-fragments of either HSV-1 or HSV-2 DNA and bound radioactivity was detected by autoradiography and counted in a liquid scintillation counter. All the three methods gave identical results for the 51 isolates studied. Twenty-six isolates were identified as HSV-1 and 25 as HSV-2. An additional 30 specimens were tested only by EIA and hybridization. Results by both techniques were in complete agreement.
