NEUTRALIZATION NEWCASTLE DISEASE VIRUS BY MONOCLONAL ANTIBODIES

Zhou Weisong Liu Xiufan( Department of Animal Science and Veterinary Medicine, Jiangsu Agricultural College )  
A panel of 23 hybridoma cell lines were used to prepare McAb specific for Newcastle disease virus ( XDV ). Nine of them showed neutralizing activity. All the McAbs inhibiting hemolysis had neutralizing capability, indicating that virus infectivity is correlated with the ability of virus to induce cell fusion. Incubation of NDV with neutralizing McAbs resulted in various degree of neutralization. Neutralizing titers in plaque redaction neutralization, cytopathic effect ( CpE ) inhibition and chick embryo neutralization assays were found to be parallel. The infectious cell fluorescent focus formation units ( ICFFU ) was reduced up to 77.6% when virus adsorbed cells were incubated with L15-6 for lhr at 4℃. CPE was inhibited by 4 McAbs(10-1, 15-1, L15-6 and LA15-7) when they were added to NDV-infected Vero cells. Immunofluorescent assay showed that virus antigen still existed in the cytoplasm of CpE inhibited cells, and CpE re-emerged in 40hr after replacement with medium without McAbs. It was postulated that McAbs could neutralize NDV by inhibiting virus adsorbtion and penetration as well as by releasing adsorbed virus from cells. Virus present in the cells could not be completely neutralized by McAbs. McAbs 15-1 and L15-6 were capable of protecting Sp F chicks aganist F48-Es virulent strain challenge at a dose of 100 LD50. McAb 15-1 showed promising therapeutic effect ia chicks even after clinical signs of experi-mantal Newcastle disease ( ND ) had appeared.
