Reactivation of koi herpesvirus infections in common carp Cyprinus carpio [PDF]

Diseases of Aquatic Organisms, 2005
Two co-habitation studies with common carp were conducted to determine whether latent infections of koi herpesvirus (KHV) exist. Fish were exposed to KHV using 2 different temperature profiles, which induced low and high initial mortality.

Initial characteristics of koi herpesvirus and development of a polymerase chain reaction assay to detect the virus in koi, Cyprinus carpio koi [PDF]

Diseases of Aquatic Organisms, 2002
Since 1998, episodes of mass mortality have occurred in populations of common carp Cyprinus carpio carpio in Israel and in populations of koi Cyprinus carpio koi in Israel and the USA. A herpesvirus isolated from infected fish has been shown in experimental studies to induce disease and mortality similar to those observed in outbreaks at infected farms.

Non-lethal diagnostic methods for koi herpesvirus in koi Cyprinus carpio

Diseases of Aquatic Organisms, 2020
Cyprinid herpesvirus 3, also known as koi herpesvirus (KHV), is a viral pathogen responsible for mass mortalities of carp worldwide. In this study, we compared the sensitivity and specificity of ELISA and quantitative PCR (qPCR) methods for the diagnosis of KHV in experimentally infected koiCyprinus carpioover an 11 mo period.

Susceptibility of koi × crucian carp and koi × goldfish hybrids to koi herpesvirus (KHV) and the development of KHV disease (KHVD)

Journal of Fish Diseases, 2010
AbstractHybrids of koi, Cyprinus carpio × crucian carp, Carassius carassius and koi × goldfish, Carassius auratus, proved to be susceptible to koi herpesvirus (KHV, syn. CyHV‐3) and developed KHV disease (KHVD). While hybrids of koi × goldfish were partly resistant to mortality following infection by immersion, most koi × crucian carp hybrids died ...

Morphogenesis of koi herpesvirus observed by electron microscopy

Journal of Fish Diseases, 2007
AbstractKoi herpesvirus (KHV or cyprinid herpesvirus 3) was inoculated onto three fish cell lines derived from carp, Cyprinus carpio L., and the process of virion formation observed with electron microscopy. Essentially, similar features of virus particles were observed in all three cell lines.

Generation of monoclonal antibodies specific for ORF68 of koi herpesvirus

Comparative Immunology, Microbiology and Infectious Diseases, 2011
Outbreaks of koi herpesvirus (KHV) infection in carp are still a serious problem worldwide. KHV is closely related to other two cyprinid herpesviruses, pox herpesvirus (CHV) and haematopoietic necrosis herpesvirus (CyHV-2) in goldfish. In this study, two major KHV antigenic proteins (ORF62 and ORF68) were identified by immunoscreening using a KHV ...

Koi herpesvirus: distribution and prospects for control in England and Wales

Journal of Fish Diseases, 2010
AbstractKoi herpesvirus (KHV) causes a highly virulent disease affecting carp, Cyprinus carpio L., and poses a serious socio‐economic threat to the UK carp industry. This study aimed to determine the geographic distribution and prevalence of KHV exposed fish in England and Wales through ELISA antibody testing.

Analysis of koi herpesvirus latency in wild common carp and ornamental koi in Oregon, USA

Journal of Virological Methods, 2013
Koi herpesvirus (KHV) infection is associated with high mortalities in both common carp (Cyprinus carpio carpio) and koi carp (Cyprinus carpio koi) worldwide. Although acute infection has been reported in both domestic and wild common carp, the status of KHV latent infection is largely unknown in wild common carp.

Impact of cyprinid herpesvirus 3 (Koi herpesvirus) on wild and cultured fish.

CABI Reviews, 2016
Abstract Common carp is a widespread freshwater fish inhabiting lower and mid streams of rivers and shallow confined waters in Eurasia. Carp aquaculture in shallow, man-made ponds has a long history and now common carp is the most widely cultured freshwater fish species in the world.

The Outbreak of Koi Herpesvirus (KHV) in Koi (Cyprinus carpio koi) from Chiang Mai Province, Thailand

The Thai Journal of Veterinary Medicine, 2009
Twenty-two sick koi with cumulative mortality showed clinical signs of depression, brachial hemorrhage and necrosis, focal hemorrhage, pale patches and ulcers on the skin. Clinical examination showed the heavy infection by opportunistic organisms such as Dactylogyrus sp., Gyrodactylus sp. and Saprolegnia sp.
