Consideration of Cause of Recent Severe Outbreaks of Newcastle Disease in Korea and a Brief Review of Virological Differences, Serological Diagnosis and Administration of a Vaccine

Since the first outbreaks of Newcastle disease ( ND) in Korea was reported in 1927, the disease has been a major problem in Korean poultry industry. Several attempts related ND prevention and controls have been tried and significantly reduced the ND outbreaks. However, recently frequencies of ND outbreaks have been increased throughout the country since 1988. Many assumptions such as variances of ND virus pathogenicity, decreased efficacy of ND vaccine, incorrect vaccination program etc, has been issued and discussed. Therefore, to clearly understand this recent situation of ND outbreaks in Korea, we reviewed all available past informations related with ND outbreaks in Korea and compared the virulence of recently isolated ND viruses with that of a reference one. Also, we discussed about some problems related with serological diagnosis. administration methods of vaccine and vaccination program.
