[The detection of the herpes simplex virus 1 and 2 antigens in clinical specimens by using monoclonal antibodies].
The possibility of using monoclonal antibodies (McAb), obtained earlier, for the detection of herpes simplex virus (HSV) in clinical specimens taken from sick and infected persons was studied. The examination of 90 persons revealed that the mixture of McAb 4A and 2C could effectively detect the presence of HSV antigen in the indirect immunofluorescence assay (IFA) directly in cells contained in cytological preparations (smears, scrapes, impressions) obtained from different organs of patients. The search of optimum combinations of McAb for the detection of HSV antigens by the method of the solid-phase enzyme immunoassay (EIA) was carried out. This study, made on purified HSV used as an experimental model, revealed that the maximum sensitivity could be achieved with the use of two McAb (4f6 and 7c4) out of three McAb (4f6, 7c4 and 3d10). The approbation of both variants of EIA on clinical specimens taken from 99 patients (blood clots, seminal fluid, scrapes of cervical canal cells, peripheral blood lymphocytes) showed that the addition of McAb 3d10 made it possible to detect 8 more positive specimens. 754 specimens from 337 patients were studied with the use of McAb-based EIA, and in 204 of these patients (61%) HSV antigen was detected. The results obtained with the use of our McAb were compared with the data obtained with certified commercial test systems. The coincidence of the EIA data with those obtained with the use of the Murex Wellcozyme HSV test system (UK) was registered in 75% of cases (in 15 out of 20 cases). The coincidence of the IFA data with those obtained with the use of the Sanofi test system (France) was observed in all 19 cases (100%).
