Koi herpesvirus and carp oedema virus: Infections and coinfections during mortality events of wild common carp in the United States.

Nucleotide sequence analysis revealed that the KHV and CEV detected here are closely related to European lineages of these viruses, which expands the known range of two important viruses.

Detection of koi herpesvirus in healthy common carps, Cyprinus carpio L.

The obtained result suggests that KHV as other member of Hervesviridae shows a latent infection in common carps, and should be anticipated for their reactivation, and it is highly recommended that commonCarps cultured in this region should be vaccinated.

Susceptibility of Pimephales promelas and Carassius auratus to a strain of koi herpesvirus isolated from wild Cyprinus carpio in North America

It is suggested that fathead minnows and goldfish are not susceptible to CyHV-3 infection and that detection of CyHv-3 DNA alone in host susceptibility trials should be interpreted with caution.

It is suggested that koi may survive CyHV-3 infections and become virus carriers.

Biocontrol of the Common Carp (Cyprinus carpio) in Australia: A Review and Future Directions

It is concluded that, while further work is required (on the virus, the target species, environmental issues, and especially the identification of a suitable broad-scale complementary control measure), optimism must prevail in order to ensure an eventual solution to this important environmental problem.

Biocontrol of Carp: More Than Just a Herpesvirus

The emphasis throughout much of the world is on viral control rather than carp control, and numerous misconceptions and misunderstandings have arisen about CyHV-3 itself, and about the viral biocontrol program for carp in Australia.

Detection of ORF6 protein associated with latent KHV infection.

Cyprinid Herpesvirus 3: An Archetype of Fish Alloherpesviruses.

Investigation of Cyprinid Herpesvirus 3 (CyHV-3) Disease Periods and Factors Influencing CyHV-3 Transmission in A Low Stocking Density Infection Trial

It was found that direct contact between fish was the primary mechanism of CyHV-3 transmission rather than transmission through contaminated water as well as the contributions of contact rate, viral load, pathogenicity and contact type.

An Unusual Koi Herpesvirus Associated with a Mortality Event of Common Carp Cyprinus carpio in New York State, USA

Koi herpesvirus (KHV), a highly contagious and lethal virus that affects both koi and common carp, was isolated in 1998 from two outbreaks of koi suffering mass mortality in New York State, USA, and in Israel.

Distribution of the introduced cyprinid herpesvirus 3 in a wild population of common carp, Cyprinus carpio L.

Results suggest that transmission of CyHV-3 from carriers to naïve common carp is still occurring in Lake Biwa, suggesting that wild common carp that survived infection become CyH V-3 carriers.

Description of an as Yet Unclassified DNA Virus from Diseased Cyprinus carpio Species

The isolation of carp nephritis and gill necrosis virus (CNGV) is reported, which is the etiologic agent of this disease, which may represent an as yet unclassified virus species that is endemic in C. carpio (carp).

MASS MORTALITY ASSOCIATED WITH KOI HERPESVIRUS IN WILD COMMON CARP IN CANADA

Koi herpesvirus (KHV) was identified as being associated with more than one mortality event affecting common carp in Canada, and sequence of the PCR product revealed 100% homology to KHV strains U and I.

Reactivation of koi herpesvirus infections in common carp Cyprinus carpio.

Two co-habitation studies with common carp were conducted to determine whether latent infections of koi herpesvirus (KHV) exist and reaction of the virus appeared to be temperature dependent.

First Detection of Koi Herpesvirus in Cultured Common Carp Cyprinus carpio in Japan

DNA of the koi herpesvirus (KHV) was detected in the gills and kidneys of moribund fish by polymerase chain reaction (PCR) assay, and the virus was isolated from those fish with KF-1 cells.

Concentrations of a Koi herpesvirus (KHV) in tissues of experimentally infected Cyprinus carpio koi as assessed by real-time TaqMan PCR.

Although there were no recognized patterns to viral DNA concentrations as found in different tissues over time, KHV genome copies for all tissues increased with time post virus exposure and with water temperature.

Investigation of Koi Herpesvirus Latency in Koi

This study suggests that KHV may become latent in leukocytes and other tissues, that it can be reactivated from latency by temperature stress, and that it may be more widespread in the koi population than previously suspected.
