Short Beak and Dwarfism Syndrome in Ducks in Poland Caused by Novel Goose Parvovirus.

Short beak and dwarfism syndrome (SBDS), which was previously identified only in mule ducks, is now an emerging disease of Pekin ducks in China and Egypt. The disease is caused by the infection of ducks with a genetic variant of goose parvovirus-novel goose parvovirus (nGPV). In 2019, SBDS was observed for the first time in Poland in eight farms of Pekin ducks.

Molecular epidemiologic investigation of Polish avian Pasteurella multocida strains isolated from fowl cholera outbreaks showing restricted geographical and host-specific distribution.

Molecular epidemiologic analyses of the 42 clinical isolates of Pasteurella multocida from various avian hosts (geese, ducks, turkeys, and laying hens) in Poland from 2001 to 2011, including a single reference strain, were performed by enterobacterial repetitive intergenic consensus (ERIC)-PCR, single primer PCR, and repetitive extragenic palindromic (REP)-PCR. Forty-two isolates were identified as P. multocida (serotype A).

Molecular characterisation of an avihepadnavirus isolated from Psittacula krameri (ring-necked parrot).

Avihepadnaviruses have been documented previously in ducks, herons, geese, storks and cranes. Here, we describe the full genome of a new avihepadnavirus isolated from Psittacula krameri (ring-necked parrot) in Poland. The parrot hepatitis B virus (PHBV) genome (3042 bp) shares <76% sequence identity with other avihepadnavirus isolates and is phylogenetically most closely related to heron and stork hepatitis B viruses isolates.
