Histomorphometric measurements of cecal villi and crypts of Campylobacter-free and Campylobacter-inoculated female turkeys. Histograms depict cecal A villus height, B villus width, C crypt depth, D villus height to crypt depth ration, and E villus surface area of female turkeys at seven, 14, and 28 days post-inoculation with sterile nutrient broth (controls), C. coli, C. jejuni, or both (co-inoculation), n = 18. Data was summarized for all three experiments. Per specimen, ten villi and ten crypts were measured microscopically at 25x and 100x magnification. Vertical error bars depict standard deviation. Different letters indicate statistically significant differences between inoculation groups at each time point (p ≤ 0.05). One-way analysis of variance, Fisher’s least significant difference test
