Emergence of fatal European genotype CyHV-3/KHV in mainland China

Cyprinid Herpesvirus 3

“…However, in the absence of comparable data from the TK gene, marker I or II regions, it is not possible to confirm this hypothesis (Han et al, 2013). In addition, some recent CyHV-3 isolates from Korea, Malaysia, and China were shown to belong to the E4 genotype which suggests the emergence of European lineages in Asia Dong et al, 2013;Kim & Kwon, 2013;Li et al, 2015).…”

“…A study in South Korea identified from disease outbreaks in 2008, both a European genotype in samples of infected common carp and the expected Asian genotype in koi carp (Kim & Kwon, 2013). More recently, a European genotype of CyHV-3 was detected from a disease outbreak in 2011 in China (Dong et al, 2013), and in imported carp from Malaysia in Singapore .…”

Myxobolus taibaiensis sp. n. (Myxozoa: Myxosporea) infecting the intestinal wall of common carp Cyprinus carpio Linnaeus in China

“…However, epizootic diseases have caused severe economic and environmental problems with the rapid development of intensive aquaculture of this species. Virosis, bacteriosis and parasitoses were increasingly reported to be responsible for the mass mortality of reared common carp (Yokoyama et al 1997, Zhang et al 2010, Dong et al 2013, Zhai et al 2016. Myxosporidiosis represents one of the most important parasitic diseases of common carp in China.…”

First Report of Occurrences of Two Cyprinid Herpesvirus 3 Variants, I⁺⁺ II^− and I⁺⁺ II^+Δ, in China

“…This virus has caused massive economic losses in Asia specifically (Sano et al, 2004;Tu et al, 2004;Bondad-Reantaso et al, 2007;Lio-Po et al, 2009;Pikulkaew et al, 2009;Han et al, 2013). Recently, CyHV-3 has also been detected in China (Dong et al, 2011(Dong et al, , 2013Zhou et al, 2014aZhou et al, , 2014b. CyHV-3 represents a member of genus Cyprinivirus belonging to the family of Alloherpesviridae and has a conserved 295 kb genome.…”

“…Although European genotype of CyHV-3 has been identified in China (Dong et al, 2013), the distribution of other genotypes in this area is still unclear. Guangdong Province is the most important koi carp culture zone in China.…”
