Recent situation of pigeon paramyxo-virus infection in pigeons in Egypt

ABSTRACT

47 pigeon lofts at different localities in Sharqia, Daqahlia and Giza were investigated for causes of nervous manifestations. Morbidity and mortality rates ranged from 15 to 80% and 10 to 65%, respectively. Paramyxovirus could be isolated from 24 cases; 14 of them were more related to pigeon paramyxovirus-1 [PPMV-1] using cross hemagglutination inhibition test and 3 more related to Montana strain of Newcastle disease virus [NDV]. Three were similarly related to both PPMV-1 and [NDV] and the last 4 less related to both PPMV-1 and Montana. The isolates showed antigenic similarity to each other and to the reference PPMV-1. On the other h and, they showed marked diversity from the Montana strain [NDV]. High percentage [88.7%] of the sera tested from the above mentioned flocks had HI antibodies against both NDV [Montana] and PPMV-1
