Abstract

Between 2008 and 2011, commercial turkey and chicken flocks in Poland were examined for the presence of turkey parvovirus TuPV and chicken parvovirus ChPV. Clinical samples 10 individual faecal swabs-flock from 197 turkey flocks turkeys aged 1 to 19 weeks and 45 chicken flocks chickens aged 3 to 17 weeks were collected in different regions of the country and tested using a PCR assay that targeted the NS1 gene 3’ORF. The prevalence of TuPV was 29.4 % in the flocks tested, while ChPV infections were found in 22.2 % of the studied flocks. Phylogenetic analysis revealed a clear division into three groups: ChPV-like, TuPV-like and a third, previously unrecognized and distinct subgroup, TuPV-LUB, containing exclusively three Polish isolates from turkeys. The isolates from the novel group showed as little as 50.6-64.5 % of nucleotide sequence identity to the prototype chicken and turkey parvovirus strains. Genetic analysis of a ChPV isolate that was classified in the TuPV group strongly suggests a recombination event between chicken and turkey parvoviruses.
