Characterization of A Herpes-like Virus Isolated from Cultured Japanese Eels in Taiwan.

Viral diseases of wild and farmed European eel Anguilla anguilla with particular reference to the Netherlands

“…Chang et al (2002) found that affected eels only showed pale and swollen gills. However, most other studies reported more severe pathological changes, such as increased mucus secretion (Ueno et al 1992, Chang et al 2002, varying degrees of erythema (M. Sano et al 1990), haemorrhages (Ueno et al 1992, Davidse et al 1999, Lee et al 1999b, Haenen et al 2002, partial fusion of the branchial lamellae resulting in mild necrosis (M. Sano et al 1990), destruction of the filament tips (Lee et al 1999b), and congestion (Lee et al 1999b, Haenen et al 2002. Overall, the most common clinical findings include apathy, varying degrees of skin and fin haemorrhages, and congestion of the gills.…”

“…The most apparent internal findings included paleness of the liver (Ueno et al 1992, Davidse et al 1999, Haenen et al 2002, multi focal haemorrhages in the liver (Ueno et al 1992, Davidse et al 1999, Haenen et al 2002, swelling of the kidney (Ueno et al 1992, Lee et al 1999b, and distension of the gall bladder (Ueno et al 1992, Haenen et al 2002. Less frequent findings include hep atic congestion (Lee et al 1999b), marked enteritis (Ueno et al 1992), an enlarged spleen (Davidse et al 1999), pink fat caused by small diffuse haemorrhages (Davidse et al 1999) and ascites (Haenen et al 2002). …”

Is There Any Species Specificity in Infections with Aquatic Animal Herpesviruses?–The Koi Herpesvirus (KHV): An Alloherpesvirus Model

“…HVA was detected during disease outbreaks in Japanese eel (Anguilla japonica) and European eel (A. anguilla) in Japan [13] and in American eel (A. rostrata) in Poland [14]. A variant of the HVA in eels in Taiwan (eel herpesvirus Formosa, FEHV) has also been found to induce mortality in common carp (Cyprinus carpio) as well [15]. From investigations conducted in our Lab it was confirmed that HVA may at least persist in artificially infected common carp (immersion) for up to six weeks, which was detectable directly by PCR and indirectly by serum neutralization assay (Bergmann, unpublished data).…”

Fish herpesvirus diseases: a short review of current knowledge

“…Thus, in the newest ICTV (International Committee on Taxonomy of Viruses) classification, AngHV-1 is assigned to the genus Cyprinivirus. AngHV-1 was isolated from farmed European eel (Anguilla anguilla) and Japanese eel (Anguilla japonica) in Japan (Sano et al 1990), from Japanese eel in Taiwan (Ueno et al 1992), and from European eel in many European countries (Davidse et al 1999;Haenen et al 2002;van Ginneken et al 2004;Jakob et al 2009). The virus was also found in wild eel populations in the Netherlands (van Ginneken et al 2004) and Germany (Jakob et al 2009).…”
