Molecular characterization of the Gyrovirus galga 1 strain detected in various zoo animals: the first report from China

Molecular analysis of Gyrovirus galga1 variants identified from the sera of dogs and cats in China

“… 2020 ; Ji et al. 2022 ). CAT03 was recombined from the major parent of HN2019-SD1 (identified in sika deer, China, 2019) and the minor parent of GS1512 (identified in chicken, China, 2015).…”

“… 2022 ), and various zoo animals (Ji et al. 2022 ). The wide prevalence of GyVg1 in chickens and other animals indicates that it may threaten human health.…”

Prevalence and phylogenetic analysis of Gyrovirus galga 1 in southern China from 2020 to 2022

“…GyVg1 is a newly discovered gyroviruses in 2011, and has subsequently been found successively in major poultry farming countries all over the world ( Sauvage et al, 2011 ; Chu et al, 2012 ; Dos et al, 2012 ; Maggi et al, 2012 ; Biagini et al, 2013 ; Smuts, 2014 ; Ji et al, 2022 ; Liu et al, 2022 ; Mase et al, 2022 ; Yan et al, 2023 ). The virus has not only been found in the brain tissues of chickens with neurological symptoms, but also has been detected in the blood of organ transplant recipients and AIDS patients, the feces of diarrhea patients, and even in the skin swabs and serum samples of healthy people, which makes it a zoonotic disease and a potential hidden danger to public health safety ( Rijsewijk et al, 2011 ; Sauvage et al, 2011 ; Chu et al, 2012 ; Maggi et al, 2012 ; Biagini et al, 2013 ; Gia et al, 2013 ; Feher et al, 2014 ; Ye et al, 2015 ).…”

“…Before 2011, chicken infectious anemia virus ( CAV ) was the only member of the genus Gyrovirus within the family Circoviridae, which is responsible for severe anemia and immunosuppression in young susceptible chickens, and was one of the most important pathogens affecting the poultry industry and the SPF breeding industry ( Rijsewijk et al, 2011 ). Since 2011, a series of circovirus sequences similar to CAV (HGyV/AGV2, GyV3 through GyV13) have been reported ( Sauvage et al, 2011 ; Chu et al, 2012 ; Niu et al, 2019 ; Feher et al, 2022 ; Ji et al, 2022 ). These viruses have been identified in birds (chicken, northern fulmar, crested screamer, ashy storm petrel, ferruginous-backed antbird, white-plumed antbird, grey teal, pigeon, Pekin duck), mammals (human, cat, dog, ferret, mice) and reptiles (king rat snake) ( Feher et al, 2014 ; Truchado et al, 2019 ; Wu et al, 2019 ; Ji et al, 2022 ).…”
