The chloroform extraction procedure enables eggs yolks to be used for antibody estimation by haemagglutination inhibition (HI) test (Piela et al., 1984). The present paper describes the use of Brij-35 (Polyoxy ethylene 23 lauryl ether) solution in egg yolks before use in th...

One hundred and twenty sera were tested by the haemagglutination-inhibition (HI) test and AGPT against NDV. There was a very significant increase in the proportion of AGPT positive samples with increase in HI tit...

Newcastle disease virus isolated from an outbreak in racing pigeons in India was found to be velogenic, based on the mean time to death in 10-day-old embryonated hen's eggs, the intravenous pathogenicity index in 6-week-old chickens and the pathogenesis in chickens and pigeons. The virus induced disease in chickens without prior adaptation in chickens. The virus wa...
