Characterization of infectious dose and lethal dose of two strains of infectious hematopoietic necrosis virus (IHNV)

Epidemiological characteristics of infectious hematopoietic necrosis virus (IHNV): a review

Infectious hematopoietic necrosis virus (IHNV, Rhabdoviridae), is the causative agent of infectious hematopoietic necrosis (IHN), a disease notifiable to the World Organisation for Animal Health, and various countries and trading areas (including the European Union). IHNV is an economically important pathogen causing clinical disease and mortalities in a wide variety of salmonid species, includ...

Comparison of selected strains of infectious hematopoietic necrosis virus (IHNV) using neutralizing trout antisera

Antisera against representative strains of infectious hematopoletlc necrosis virus (IHNV) from each of the 5 electropherotypes were prepared in rainbow trout Oncorhynchus mykiss following injections with live virus. Serum cross-neutralization comparisons by 50 % plaque neutralization tests (PNT) showed low antigenic heterogeneity between the vlruses, as calculated by l / r , a measure of the an...

Early Kinetics of Infectious Hematopoietic Necrosis Virus (IHNV) Infection in Rainbow Trout

—A series of experiments was carried out with infectious hematopoietic necrosis virus (IHNV; 193-110 isolate) in rainbow trout Oncorhynchus mykiss (weight, ;1.2 g) to determine the duration of the patent period and the timing of onset of the infectious periods. We first attempted to transmit IHNV to recipient fish from infected rainbow trout 2–3 d after they had been exposed. No infection trans...

Simultaneous Detection of Infectious Hematopoietic Necrosis Virus (IHNV) and Infectious Pancreatic Necrosis Virus (IPNV) by Reverse Transcription (RT)-Polymerase Chain Reaction (PCR)

Multiple virus infections have recently been observed during routine examination of salmonid fish.1) Infectious hematopoietic necrosis virus (IHNV) and infectious pan creatic necrosis virus (IPNV) are often isolated together or with other viruses, such as a herpes virus or a retro-like virus.1,2) In case of multiple virus infections, only the virus which replicates most efficiently will be dete...
