To select a less pathogenic bovine viral diarrhea virus (BVDV) strain for the construction of chimeric pestivirus harboring classical swine fever virus (CSFV) E2 gene, five Korean BVDV isolates (four type 1 isolates and a type 2 isolate) were evaluated for their pathological and biological properties with respect to porcine infection. Each of five groups of 100-day-old pigs was inoculated intranasally with one of the five BVDV isolates. No clinical sign or leukopenia was observed in any pig throughout the duration of the experiment, but viruses were detected in blood, nasal discharges and postmortem samples using RT-PCR. These results indicated that although the five BVD viruses could infect pigs, they did not cause clinically apparent symptoms. Because of its proper infection dynamics shown in this preliminary animal study and its fast growth rate and quick CPE in cell culture, one isolate (KD26-1) was chosen among the five isolates to test its virulence and immunogenic properties in 40-day-old piglets. Neither clinical sign nor pathological lesion was observed in 40-day-old piglets during the course of infection of isolate KD26-1. The first neutralizing antibodies were detectable 14 days post-inoculation (PI) and increased to 1:128~1:256 28 days PI. A BVDV specific gene was detectable by RT-PCR in tonsil, spleen, inguinal lymph node and brain until 14 days PI. According to this study, it can be concluded that isolate KD26-1 has little pathological effect in pigs and is a candidate for construction of chimeric pestivirus harboring CSFV E2 gene.
