Age-wise and Sex-wise prevalence of Paratuberculosis carried out along with the overall prevalence of the disease using Indigenous ELISA. A total number of 100 sheep sera samples were screened. The age-wise prevalence was detected as 18.75 percent in less than 6-month age group, 21.05 percent in 6-12 months age group and 43.75 percent in more than 12 months age group. Sex-wise sero-prevalence was detected as 18 percent and 13 percent in male and female sheep respectively. An overall seroprevalence of Paratuberculosis was found to be 31 percent.
