Abstract

This study describes the first isolation and genetic characterization of the newly emerging porcine circovirus type 2e (PCV2e) from Korean pigs. The PCV2e isolate did not produce a cytopathic effect in PCV-free PK-15 cells; therefore, PCV2e infection was demonstrated by immunohistochemistry with polyclonal PCV2a antibodies and polymerase chain reaction with primers specific for PCV2e. As the infected PCV-free PK-15 cells were passaged, the amount of infectious virus correlated with an increase in the amount of viral DNA (i.e., a decrease in the cycle threshold values. A full genomic analysis of the PCV2e strain SNUVR199711 was performed and showed that the genome is 1,777 nucleotides in length.
