Effect of route of Newcastle disease vaccination on the incidence of airsacculitis in chickens infected with Mycoplasma synoviae.
In two separate experiments, broiler-type chickens were vaccinated at 11 days old with either the B-1 or LaSota strain of Newcastle disease virus (NDV) by aerosol, drinking water, or eyedrop and simultaneously infected with Mycoplasma synoviae (MS). The MS-infected and aerosol-vaccinated chickens had the highest mean lesion scores for airsacculitis. The aerosol-vaccinated groups had the highest hemagglutination-inhibition titers against NDV. Infection with MS had no effect on antibody titers against NDV, and there were no consistent effects on weight gains.
