Herpes simplex virus was detected in the clinical specimens of two patients with Kaposi’s varicelliform eruption by
in situ hybridization method using a commercially available DNA probe kit. To detect herpes simplex virus DNA directly, we applied this
in situ hybridization method to identify the herpes simplex virus of two patients with Kaposi’s varicelliform eruption. Case 1 was a 27-year-old male, case 2 was a 54-year-old-female, and both patients were suffering from adult type of atopic dermatitis. Recently, many trials using
in situ hybridization methods with radiolabelled nucleic acid probes have been reported for detecting viral DNA, and it is suggested that this method is more closely related to infectivity, when compared with other more conventional immunohistochemical methods. More recently, some biotinylated probes have become available, which make such assays possible without the inherent disadvantages of working with radioactive reagents as well as saving time. Viral DNA was found either granularly or agglomerately, in the nuclei of giant cells and ballooning cells in the vesicles. The viral antigen in one case was identified by monoclonal antibodies specific for herpes simplex virus-1, 2. The herpes simplex virus-1 antigen was found peripherally in the nuclei of infected cells. We believe that the
in situ hybridization method using a non-radioactive probe is useful in examining viral-infectious diseases, because it is rapid, direct and safe.
