  • a That is, the mean fecal shedding score range. Animals were only included in the “0” category if all three fecal culture tests were done and found to be negative.

  • b Pos/total and Neg/total, number positive and number negative/total number tested, respectively. Superscript numbers 1, 2, 3, and 4 indicate statistical comparisons among tests for each fecal score (within rows). Different numbers indicate significant differences in the percentages of positive tests (P < 0.05).
