Viral Diseases of Fish: First Report of Carp Pox in Golden Ide (Leuciscus Idus) in North America

Abstract

Carp pox, a putative viral disease exotic to North America, occurred in golden ide 1 yr after the fish were imported into the United States from the Federal Republic of Germany. The raised, white, plaque-like lesions, which occurred on about 5% of the fish, healed spontaneously and caused no mortality. Electron micrographs showed herpesvirus-like particles associated with lesion specimens; however, no infectious viruses were detected in tests with seven warmwater fish cell lines.

Virus-associated epidermal hyperplasia in golden ide Leuciscus idus meianotus

“…The viral particles they described (dimensions: enveloped particles ca 115 nm, capsid ca 60 nm, core ca 53 nm) differ somewhat from those observed in this study (160 to 180 nm, 90 to l10 nm, 60 to 80 nm respectively), but morphological and pathological characteristics of the particles and skin lesions are similar. This most likely indicates that the virus described by McAllister et al (1985) and the one described here are identical pathogens. The differences in size may represent differences in specimen preparation.…”

“…Among golden ide originally imported from Germany, McAllister et al (1985) described an infection with a herpesvirus which was associated with white plaque-like lesions of skin and fins. The viral particles they described (dimensions: enveloped particles ca 115 nm, capsid ca 60 nm, core ca 53 nm) differ somewhat from those observed in this study (160 to 180 nm, 90 to l10 nm, 60 to 80 nm respectively), but morphological and pathological characteristics of the particles and skin lesions are similar.…”

“…Viral particles from golden ide were also very similar to those associated with epithelioma papillosum of common carp Cyprinus carp10 (Schubert 1964, 1966, Sano et al 1985a. Attempts to isolate the herpesvirus from golden ide LITERATURE CITED in our study and by McAllister et al (1985) and from epithelioma papillosum of koi carp (Hedrick & Sano 1989) were unsuccessful. Epidermal hyperplasia as observed in our study and others was seasonal with fish being affected mainly in early spring (McAllister et al 1985) and early summer (Hedrick & Sano 1989).…”

Temperature-dependent replication of herpesviruses of fish has been observed.…”

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

“…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). The cyprinid herpesvirus 1 (CyHV-1, carp pox virus) induced typical clinical signs in carp or koi (C. carpio), in golden ide (Leuciscus idus) [16] or in other cyprinids (carps and minnows) [17]. CyHV-2 or goldfish herpesvirus was first detected in goldfish (Carassius auratus), inducing severe disease outbreaks in those affected populations [18,19].…”
