Description

Infectious diseases in aquaculture rarely occur on their own. Coinfections - mixed or associated occur commonly. Infectious pancreatic necrosis is a viral infection that occurs in juvenile trout. The IPN virus is very resistant, the transmission is vertical and horizontal and the sustainability out of the host is huge. In Bulgaria, mixed infections involving fish viruses are not enough studied. The global data is also insufficient. Trout aquaculture in our geographical settings often suffer from slight parasitic invasions and transitory bacterial infections. Notably, when it is established under certain factors, some of them become epizootic. The world's largest burden is onto viral infections. They occurs rarely but with incorrigible damages. For the past 8 years in Bulgaria only the IPN virus – in seemingly acute form, has been detected. This work presents clinical cases identified in the NRL BRMMP and a summary of the current global experience of the IPN coinfections – mixed and associated.
