  2. Abbreviation: SI semi-intensive.
  3. Factors associated with T. gondii seropositivity in study districts with their frequency (N), % Prevalence, crude odds ratio (cOR) and corresponding 95% confidence interval (95% CI) in the univariable logistic regression analysis (using 1130 sheep sera from 3 districts and 227 flocks).
