CSF In PIGs

Classical Swine Fever (Hog Cholera) in Pigs

Hog cholera or classical swine fever (CSF) is a highly contagious multisystemic haemorrhagic viral disease of domestic pigs, wild boars, pygmy hogs, and feral pigs. It is economically damaging and can spread quickly through large populations.

How to Diagnose

1. Hog cholera affected adult pig having high temperature and a tendency to hide inside straw.

   

2. Affected piglets show high fever, rough hair coat, and incoordination in movement.

   

3. CSF affected pigs showing posterior paralysis.

   

4. CSF affected pigs lie down and are reluctant to move.

   

5. Pinpoint to pinhead haemorrhages on the skin of CSFV-infected pigs.

   

6. Patchy haemorrhages on the skin of CSFV-infected pigs.

   

7. Chronic CSFV infection causes diarrhoea, debilitating condition, and posterior weakness.

   

8. Sloughing of skin in the ear of CSF-affected adult pig.

   

9. Abortion in CSF virus-infected pregnant sows.

   

Type of Samples

From ailing pigs: serum and blood. In dead pigs: tissue samples like tonsil, lymph node, spleen, kidney, ileal loop.
