Overview

Background The intensification of poultry production and the constantly growing number of geese flocks in Poland increases the risk of infectious diseases. The study aimed to determine the health status of commercial geese, with particular emphasis on infections with goose parvovirus (GPV), goose circovirus and goose hemorrhagic polyomavirus. The study monitored 27 geese flocks, ranging in size from 3,000 to 13,000 birds, over a two-year period. Results The results showed the presence of genetic material GPV in all flocks tested, whereas GoCV and GHPV were detected in some flocks, 44.4% and 59.3% respectively. A significant number of flocks were found to be co-infected with two (74.1%) and three viruses (22.2%). Additionally, a phylogenetic analysis of GPV and GHPV was conducted based on a fragment of the virus genome, while for GoCV the phylogenetic analysis was performed on whole genome. Analysis of the vp1 gene revealed that 30.8% of the sequences obtained belonged to a variant of the virus known as novel GPV, so far attributed to short beak and dwarfism syndrome in Pekin ducks. The majority of the GoCV genomic sequences exhibited high homology to the Polish sequence, which was previously isolated from domestic geese. Only one sequence was found to be closely related to sequences from wild birds. Conclusions Our research indicates that viral and bacterial co-infections are a significant problem in flocks of geese. Rarely did a single factor have a clear impact on the health status of the flock. Typically, mixed viral infections, as well as bacterial complications (mainly Escherichia coli , less frequently Ehrysipelotrix rhusiopathiae , Gallibacterium anatis , and Salmonella Typhimurium), or fungal complications lead to an increase in mortality in the flock, growth diversification of birds, and thus a reduction in production rates.
