“…As a result, the salmonid aquaculture in France, Italy, and Germany suffered heavy economic losses. In Balkan Peninsula IHNV was detected in Slovenia in 2002 (7), Croatia in 2007 (8), and Kosovo in 2011 (9).…”

“…However, this isolate is closely related to recent isolates from Germany, Italy and Iran. French isolates may represent the origin of several German IHNV isolates (11), and the French IHNV genotype has spread through the European countries mainly through the trade of infected fish, fry and eggs (12). The other countries in the region (Serbia, Bulgaria and Greece) that have implemented the Directive 2006/88: European Union animal health requirements for aquaculture animals and products, have surveillance program for listed aquatic disease, but there have been no positive IHNV reports.…”

Infectious hematopoietic necrosis (IHN) is a common disease in the intensive production of salmonids. The IHN virus (IHNV) was isolated for the first time in North Macedonia in 2018. This study aimed to investigate the distribution and genotype of IHN in farmed rainbow trout and autochthonous salmonid fish in North Macedonia following the first detection. The samples were collected from 47 trout farms. Trout fry with or without clinical signs of IHN were selected as individual samples. Kidney, spleen, and heart were taken from each fish during the dissection. Three pooled samples were collected from each farm. A total of 141 pooled samples were collected: Rainbow trout (Oncorhynchus mykiss) n=127, Macedonian trout (Salmo macedonicus) n=11, and Ohrid trout (Salmo letnica) n=3. The virus was detected in 43 samples (30.50%): rainbow trout (n=40), Macedonian trout (n=2), and Ohrid trout (n=1). There were 18 (38.30%) positive fish farms. The MAKIHNV1 isolate from 2018 (MN641902) and the newly isolated virus shared a similarity of >99 and were placed in clade E-1 of European genogroup E. The IHN has spread throughout the country and is also present in the autochthonous salmonids.
