Major histocompatibility complex class I (MHC I) molecules play a vital role in adaptive immune systems in vertebrates by presenting antigens to effector T cells. Understanding the expression profiling of MHC I molecules in fish is essential for improving our knowledge of the relationship between...

The aim of this work was to investigate the origin and spread of the virus in the Czech Republic using conventional and molecular epidemiology, including partial genomic analysis of individual viruses. Host species was predominantly common carp and koi (Cyprinus carpio). With one exception, all...

Cyprinid herpesvirus-3 (CyHV-3) is an important pathogen of common carp (Cyprinus carpio, carp) causing significant economic and ecological impacts worldwide. The recent emergence of CyHV-3 in the Upper Midwest region of the United States has raised questions related to the disease ecology and host ...

Cyprinid herpesvirus 3 (CyHV-3) can induce up to 100% mortality among carp populations. To date, there has been no safe method to prevent the consequences of the activity of CyHV-3. Thyme is widely used in cooking due to its flavour. Both thyme and thyme essential oil (TEO) are used in traditional...

Ranavirus has a wide range of hosts, can infect reptiles, fish and amphibians, and lead to a high mortality. In order to further enrich its detection methods, in this study, a pair of specific primers was designed for the frog virus type 3(FV3) based on its major capsid protein gene, and two other...

Haematopoietic necrosis in Carassius carassius is one of the most damaging diseases in recent years caused by Cyprinid herpesvirus 2 (CyHV-2). CyHV-2 belongs to the family Alloherpesviridae and the genus Cyprinivirus. The genus also includes Cyprinid herpesvirus 1 (CyHV-1), Cyprinid herpesvirus 3...

To study the disinfection validity of compound peroxymonosulfate powder in aquaculture, we evaluated its killing effect on grass carp (Ctenopharyngodon idella) reovirus (GCRV), channel catfish (Ictalurus punctatus) virus (CCV), Aeromonas hydrophila and Streptococcus agalactiae, and studied the...

Koi herpesvirus disease (KHVD), caused by Cyprinid herpesvirus-3 (CyHV-3), is one of the most serious threats to carp farming. In the present study, we investigated the efficiency of a low-density (LD) SNP panel for estimating genetic parameters and breeding values to KHVD resistance in the Amur...

A major threat to gibel carp aquaculture is an epizootic disease caused by C. auratus herpesvirus (CaHV). Therefore, breeding of disease resistant strain is one of significant needs for the industry. Polyploids often show enhanced tolerance to abiotic or biotic stress. However, the effects of WGD...

Gibel carp (Carassius auratus gibelio) is an important economic fish species in China, but its development is seriously restricted by the crucian carp hematopoietic organ necrosis caused by Cyprinid herpesvirus 2 (CyHV-2). Gill is the key portal for CyHV-2 primary invasion, and the gill immune...
