A total of 50 fresh fecal droppings were collected from each farm in the five samplings (week 1, 4, 9, 13, and 19) and 20 viscera/ceca were collected at slaughtering plant from each farm.
For each farm prevalence, numbers in the same column with different letters in the superscript were significantly different (p<0.05), while numbers with the same letters did not differ significantly (chi-square test and Fisher's exact two-tailed test).
