Question

The IPN (Infectious Pancreatic Necrosis) and VMS (Viral Hemorrhagic Septicemia) are well known infectious diseases of
A. Fish
B. Cattle
C. Poultry
D. None of the above

Answer 1

Hint: IPN is Infectious Pancreatic Necrosis. It is characterized by swollen abdomen and eyes. It is caused by Aquabirnavirus, which can be confirmed by ELISA test and PCR test. VMS is Viral Hemorrhagic Septicemia. It occurs mainly in the northern hemisphere and it is very deadly. It is caused by Novirhabdovirus. It will cause sunken eyes and bleeding around eye sockets.

Complete answer:
Option A Fish: IPN affects salmon fish and VMS affects more than 50 species of marine fishes.
Option A is correct.
Option B Cattle: Cattle are not affected by PIN and VMS. Instead, cattle are affected by cattle plague or rinderpest. Rinderpest disease is caused by the virus belonging to the Paramyxoviridae family. It destroys lymphoid organs.
Hence, Option B is not correct
Option C Poultry: PIN and VMS diseases are not found in poultry. Infectious bursal disease is a viral disease in poultry. It occurs in young chickens. White diarrhea is caused. The virus belongs to the Birnaviridae family.
So, Option C is not correct
Option D None of the above: This option is not taken into account as fish is being affected by both IPN and VMS.
Option D is not correct

Hence, Option A is the correct answer

Note:
IPN can be transmitted to progeny from parents. Hence, eggs obtained from parents should be destroyed immediately. In fresh water and salt water, IPN is easily transmitted. It can survive in the guts of birds and mammals and comes out through faecal matter. VMS is transferred through contaminated water by bait fish. In addition, it is transmitted from one fish to another through infected eggs. If an organism survives the virus, it may become a lifelong carrier of the virus.
