“…Furthermore a relationship has been found between the effective population size and epidemics of GPV. Since 2000, many studies about GPV outbreak in Sweden, Britain, and China have been reported ( Jansson and Palya, 2007 ; Irvine et al, 2008 ; Chen et al, 2016 ). We estimated the R 0 of GPV clades 1 and 2 of 1.043 (assuming D = 0.3 month) and 2.001 (assuming D = 1 month).…”

Waterfowl parvoviruses are classified into goose parvovirus (GPV) and Muscovy duck parvovirus (MDPV) according to their antigenic features and host preferences. A novel duck parvovirus (NDPV), identified as a new variant of GPV, is currently infecting ducks, thus causing considerable economic loss. This study analyzed the molecular evolution and population dynamics of the emerging parvovirus capsid gene to investigate the evolutionary processes concerning the host shift of NDPV. Two important amino acids changes (Asn-489 and Asn-650) were identified in NDPV, which may be responsible for host shift of NDPV. Phylogenetic analysis indicated that the currently circulating NDPV originated from the GPV lineage. The Bayesian Markov chain Monte Carlo tree indicated that the NDPV diverged from GPV approximately 20 years ago. Evolutionary rate analyses demonstrated that GPV evolved with 7.674 × 10-4 substitutions/site/year, and the data for MDPV was 5.237 × 10-4 substitutions/site/year, whereas the substitution rate in NDPV branch was 2.25 × 10-3 substitutions/site/year. Meanwhile, viral population dynamics analysis revealed that the GPV major clade, including NDPV, grew exponentially at a rate of 1.717 year-1. Selection pressure analysis showed that most sites are subject to strong purifying selection and no positively selected sites were found in NDPV. The unique immune-epitopes in waterfowl parvovirus were also estimated, which may be helpful for the prediction of antibody binding sites against NDPV in ducks.

“…This may include endemic, new and emerging, re‐emergent or notifiable avian diseases. Recent examples of such diseases identified by the VLA through scanning surveillance activities include avian encephalomyelitis (Welchman and others 2009), IBV QX (Gough and others 2008), goose parvovirus (Irvine and others 2008), avian vibrionic hepatitis (Crawshaw and Young 2003), two outbreaks of notifiable avian influenza (Anon 2008, Slomka and others 2010) and two outbreaks of Newcastle disease (Aldous and others 2007, Irvine and others 2009). The VLA's scanning surveillance activities, in partnership with private veterinary surgeons, continue to detect disease threats in Great Britain, thereby highlighting hazards and risk pathways that may exist for the poultry industry and poultry populations in general.…”

“…GPV infection has also been reported in England and Wales and clinical symptoms and pathological changes were identical to the changes described in geese in Poland. In Sweden mortality of birds due to infection with GPV was from 40% to 90% (Takehara et al 1995, Jansson et al 2007, Irvine et al 2008.…”

The aim of this study was to determine the infectious agents isolated from infection -suspected geese sent for the diagnostic examination to National Veterinary Research Institute. The birds were sent from goose flocks localized in different parts of Poland. Totally, 1,013 birds from 122 flocks were examined. The presence of goose parvovirus (GPV), goose haemorrhagic polyomavirus (GHPV), and goose circovirus (GoCV) was detected by triplex PCR. The presence of GPV DNA was shown in 36 flocks. The disease was most frequently diagnosed in goslings aging 3.5 weeks (ten flocks), and 2.5 weeks (six flocks). The analysis of the nucleotide sequence of VP1 encoding region has shown close similarity of Polish GPV strains within the group which ranged from 92% to 100%. Moreover, the similarity level of these strains with GPV isolated in Europe was from 91.3% to 100%. The occurrence of GoCV DNA was shown in 25 goose flocks. The presence of GoCV DNA was found among geese aged from 2 to 6 weeks, but predominantly in those aging 3.5 (three flocks) and 5 weeks (five flocks). The sequence analysis of PCR products from the sequenced region of ORFC1 capsid protein of GoCV has shown that Polish isolates share from 85% to 91% similarity with the sequences of GoCV strains isolated in other countries. The presence of DNA of GHPV was found in 3-week-old geese. During the last 2 years the presence of GHPV was confirmed in three flocks of goslings at the age from 3 to 3.5 weeks. During the last 12 years the occurrence of co-infection with GPV and GoCV was detected in six flocks aging from 5 to 6 weeks.
