Abstract

|
|
This study was carried out to understand the recent prevalence of Kazba virus using 8,023 sera collected during the year 1989~2000. Seropositive rates to Kazba virus showed the highest antibody rate(86.7%) in 1994, decreased up to 22.8% in 1997, and then largely fluctuated its levels including 60.8% in 1998 and 5.8% in 1999. Mean seropositive rates to Kasba virus from 1999 to 2000 year recorded 9.9% respectively. Therefore, positive rates of neutralizing antibody against Kazba viruses showed continuous low level during the past 3~4 years. Seropositive rates of neutralizng antibodies against Kasba virus in cows by age showed high level as they grew old. The Kasba virus showed a peak of 16.3% at their 5~6 ages.
