Phylogenetic analysis and genotyping of Iranian infectious haematopoietic necrosis virus (IHNV) of rainbow trout (Oncorhynchus mykiss) based on the glycoprotein gene.

ABSTRACT:

Background

Infectious haematopoietic necrosis (IHN) is known as one of the most contagious systemic viral diseases in salmonids which can lead to significant mortality rates and negative impacts on the salmonid farming industry. Infectious haematopoietic necrosis virus (IHNV) was first detected in rainbow trout (Oncorhynchus mykiss) farms in Iran in 2003.

Objectives

We conducted the present study to determine the detection of IHN genotypes in rainbow trout (O. mykiss) in farms in the central parts of Iran, using molecular and phylogenetic techniques.

Methods

Samples were collected from fries exhibiting clinical signs such as darkening of the skin, abdominal swelling, and loss of appetite. Phylogenetic analysis was performed by the neighbour-joining method, using MEGA
