title: Detection of herpes simplex virus-1 by nested PCR. An experimental model.
abstract: Nested polymerase chain reaction (nested PCR) was performed using a reaction mix batch-prepared and kept frozen in single reaction tubes at -20 degrees C until use. Twenty-one New Zealand white rabbits were infected with herpes simplex virus type 1 (HSV-1). Eleven animals were killed on day seven and the other ten were sacrificed on day 21. Viral culture and nested PCR was used to determine the presence of HSV-1 in samples from the tongue, HSV-1 was detected in 90.47% of the animals; in 84.21% by nested PCR and in 52.63% by culture. Nested PCR assay had greater sensitivity than culture in animals sacrificed on day seven with significative difference (p < 0.05). Higher sensitivity and faster results were obtained with this method, so we found it reliable and useful in the setting of a clinical laboratory dealing with diagnosis of herpes virus infections.
