Abstract
Aim:
The present study was conducted to know the current scenario
of classical swine fever (CSF) in Bengaluru Urban, Bengaluru
Rural, Chikkaballapur, Madikeri, Mandya, Bagalkot, Gadag, Yadgir,
Koppal, and Bidar districts of Karnataka with the using of both
antigen and antibody ELISA.
Materials and Methods: We collected 218 sera and 121 blood
samples from pigs from 10 different districts of Karnataka.
Screening of sera for CSF IgG antibody and whole blood for CSF
virus antigen were carried out using the CSF virus (CSFV) antibody
and antigen ELISA kits, respectively.
Results: The mean seroprevalence was 41% (89/218) and
prevalence of CSFV antigen in blood samples was 32% (39/121) for
the 10 districts of Karnataka. Seroprevalence of 61%, 29%, 20%,
and 21%; and antigen prevalence of 40%, 50%, 13%, and 12% were
recorded for Bangalore, Mysore, Belgaum, and Gulbarga divisions of
Karnataka, respectively.
Conclusions: The study revealed an
alarmingly high prevalence of CSF, both for the antigen (32%) and
antibody (41%) in Karnataka. Southern Karnataka has the highest
seroprevalence (61% in Bangalore and 29% in Mysore divisions),
which confirms the endemicity of the disease in that region. This
could be attributed to the intensive pig farming practices in the
region as compared to Northern Karnataka (Seroprevalence of 20% in
Belgaum and 21% in Gulbarga divisions), where the commercial pig
farming is still in infantile stages.
Keywords: antigen, antibody, classical swine
fever, ELISA and prevalence.
