# Evidence of goose circovirus identified in Muscovy ducks

## TL;DR

Goose circovirus was found in Muscovy ducks in China, suggesting it can spread between species and affecting disease control strategies.

## Contribution

Identification of goose circovirus in Muscovy ducks and analysis of its genetic characteristics.

## Key findings

- DuGoCV shares 89.2–95.9% genome sequence identity with GoCV reference strains.
- Phylogenetic analysis placed DuGoCV in the GoCV-III genotype.
- The study suggests cross-species transmission between geese and Muscovy ducks.

## Abstract

Goose circovirus (GoCV) has been found in waterfowl more than 20 years, causing considerable economic loss worldwide. In the present study, goose circovirus (designated DuGoCV) was identified in Muscovy ducks in China, with complete genomes were sequenced and analyzed. The genetic evolutionary characteristics and recombination patterns of different genotypes were examined. The DuGoCV strain shared genome sequence identities of 89.2–95.9% with the GoCV reference strains and 67.0–67.1% with the DuCV reference strains. Phylogenetic analysis revealed that the DuGoCV strain belongs to GoCV-III. These findings suggest possible cross-species transmission of GoCV between geese and Muscovy ducks, providing important insights for the prevention and control of GoCV infection.
