Abstract

This study aim to detect the prevalence of parvovirus cause the shortbeak disease and some clinical characteristics on waterfowls infected with parvovirus. The study was conducted in 06 nothern provinces including Bac Giang, Bac Ninh, Lang Son, Hung Yen, Thai Nguyen and Ha Noi. The internal organs of suspected disease waterfowls were collected from the farms and households and mixed for PCR reaction. The results of PCR detection indicated that, 52 positive samples (43.33%) from 120 sick waterfowl samples. The mainly clinical signs on ducks infected with Derzsy’s disease including short beak, dwarfism, anorexia, uropygial glands and eyelids are swollen. The beak of waterfowl infected with parvovirus is shorter than the normal one, the beat of sick duck is shorter 35.25%, while the beak of muscovy duck is shorter 33.61% as compare with the normal one. Hence, the positive results of PCR reaction showed the prevalence of parvovirus on waterfowls at some northern provinces, the size of sick waterfowl’s beak showed shorter than as compare with the normal one.
