Comparison of the Scott Selecticult-HSV kit with conventional culture and direct immunoperoxidase staining for detection of herpes simplex virus in cultures of clinical specimens.

RESUMO

In a comparative study, clinical specimens were cultured for herpes simplex virus (HSV). The presence of virus was noted by the appearance of characteristic cytopathic effect, as determined by standard direct immunofluorescence techniques, by using a direct immunoperoxidase stain for viral antigen, or by using the Selecticult-HSV (SC-HSV) stain for viral antigen. There was 100% correlation between the SC-HSV stain and immunofluorescence staining in recognizing HSV-infected cells (81 of 81 positive specimens). In comparison with observation of cytopathic effect, the SC-HSV system and conventional culture detected 93 and 78% of positive cultures at 48 h postinoculation and 76 and 32%, respectively, at 24 h. By 5 days postinoculation, SC-HSV detected 100% of the positive specimens. As compared with the direct immunoperoxidase stain, SC-HSV stain was slightly more sensitive and gave less background stain. HSV serotypes 1 and 2 were both detected by the SC-HSV stain. The Scott SC-HSV kit appears to be an effective system for the diagnosis of HSV infections.
