Average E. coli counts (A) and their correlation with the severity of macroscopic lesions (B) in caeca of turkeys. A Groups are as follows: negative control (birds not inoculated with H. meleagridis), no lesion (birds inoculated with H. meleagridis that showed no lesions), mild lesion (birds inoculated with H. meleagridis that showed LS 1), severe lesion (birds inoculated with H. meleagridis that showed LS 3 or 4). Results are expressed as mean±SEM, values with different letters are statistically significant; B Spearman’s correlation coefficient of caecal lesion score with bacterial load of E. coli count in caeca. Lesion scores were assigned based on the previously published scoring scheme [31].
