Table 3 Mean gross lung lesion score (GLLS) and microscopic lesion scoring (standard deviation) in samples from three different anatomical sites of the trachea at different days post-infection (DPI): Cranial trachea (CT), Medium trachea (MT), and Lower trachea (LT) of experimentally inoculated animals with M. hyopneumoniae strain 232. Lungs were scored using the Christensen et al. (1999) [17] methodology. No significant differences (P < 0.05) were found using Tukey test or linear mixed-effects model test adjusted for Tukey
