Direct detection of bovine herpes virus-1 DNA from cell culture fluids using polymerase chain reaction.

ABSTRACT

A pair of oligomers of 20 and 23 bp were designed for amplifying a 381 bp sequence from glycoprotein IV gene of bovine herpesvirus 1. The primer pairs were used for amplifying genomic DNA of BHV-1 directly from cell culture fluids under different experimental conditions such as, untreated cell culture fluid, thermal denaturation and proteinase K treatment in presence of detergent. The results reveal that direct thermal denaturation of cell culture fluid is sufficient to detect the virus by polymerase chain reaction.
