Detection rates (percentage positive) for S. obvelata-exposed mice, comparing the tape test (20 mice per time point; n = 60 total), examination of intestinal contents (10 mice per time point; n = 30 total), Swiss roll histology (10 mice per time point; n = 30 total), and PCR analysis (20 per time point; n = 60 total) on days 0, 30, 90, and for all time points combined. The ‘total positive’ data represent the number of mice positive by at least one test method (20 mice per time point; n = 60 total). The number within the bar represents the number of positive mice. ‡, P = 0.001 (McNemar test) for PCR analysis compared with the tape test for all time points combined.
