ABSTRACT
PCR following two methods of DNA extraction was used to confirm the growth of camel pox virus (CPV) and vaccinia virus in cell culture and chorioallantoic membrane. Results were compared with the commonly used neutralization test. The first method of DNA extraction was accomplished by using viral DNA in tissue culture supernatant and Chorioallantoic membrane, which was released by initial heating for 15 min at 99 degrees C followed by ordinary PCR. In the second method DNA was extracted by using DNA Isolation Kit from tissue culture supernatant and used as a template. Rapid identification and differentiation of CPV and Vaccinia virus were achieved by PCR and this assay proved to be fast and feasible, and can be an alternative to orthodox serological methods.
