Experimental infection of turkeys with egg drop syndrome 1976 virus and studies on the application of the haemagglutination inhibition test.

Evidence that turkeys can be infected with virus 127 by the combined intranasal and oral route and that the haemagglutination inhibition (HI) test can be used to demonstrate past infection is presented. Experimental infection of turkeys (six weeks old and six months old) with virus 127 did not result in any clinical signs. However, a rapid HI response was detectable one week later and detectable titres were found 28 weeks after infection. No antibody was detected in 392 sera examined from commercial turkey flocks.
