2013年8月26日 · Positive detection of KHV DNA using PCR indicates that the virus is present, so it can be used to confirm KHV disease in clinically sick fish and perhaps even to identify carriers (Eide et al. 2011). One indirect testing method for KHV that has been widely used is the enzyme-linked immunosorbent assay (ELISA).

6 小时之前 · The phylogenetic tree of koi herpesvirus (KHV) reveals the molecular relationship between viral strains from two geographical regions of carp fish farming in Iran and strains existing worldwide.

2020年6月15日 · Koi herpesvirus (KHV) is a highly contagious viral pathogen of common carp and koi carp varieties. Mortality rates can be 80-100% in some cases. Lowering the water temperature to <15°C can reduce mortalities, but fish that recover can become persistently infected and are a major source of concern for the spread of the virus.

KHV is a DNA-based virus. After discovery, it was identified as a strain of herpesvirus. Like other strains, KHV stays with the infected fish for the duration of their lives, making the recovered and exposed fish potential carriers of the virus. Koi fish infected with KHV may die within the first 24–48 hours of exposure.

2024年5月19日 · Koi herpesvirus (KHV) presents a significant threat to koi populations worldwide, causing severe mortality rates and economic losses within the ornamental fish industry. Identifying key indicators of KHV infection is crucial for prompt diagnosis and effective management.

2020年7月1日 · KHVD in common carp and koi is characterized by external clinical signs like lethargy and food refusal three to nine days post infection (dpi), followed by an enormous increase in mucus production on skin and gill tissues, frequently enophthalmus (Fig. 2b), later on focal and expanded necrosis of the gill tissues (Fig. 2a), round to massively ex...

koi herpesvirus (KHV), koi herpesvirus disease (KHVD), pathogenesis and virus variants. Different KHV lineages have clearly been identified, possible genomic changes during replication in different cell cultures at different temperatures but also in several hosts have been identified, a persistent stage of

Over the last years, there has been an enormous increase in the knowledge on koi herpesvirus (KHV), koi herpesvirus disease (KHVD), pathogenesis and virus variants. Different KHV lineages have clearly been identified, possible genomic changes during replication in …

First recognized in 1996, Koi herpes virus (KHV) is a double stranded DNA virus that infects ornamental koi and common carp. It is found in these fish worldwide. KHV can cause disease seen in aquaculture as well as in ornamental fish, but is not often observed in the wild.

2020年2月19日 · The non-koi herpesvirus disease (KHVD)-susceptible salmonid fish were demonstrated to transfer KHV to naïve carp at two different temperatures including a temperature most suitable...
