Table 1. Immunopathological data obtained from the experimental study.

Number (%) of animals showing CVPC, mean Ph. Eur. Score (± SD), mean S/P ratio (± SD) and number (%) of seropositive (IgG) and positive animals to M. hyopneumoniae-IgG1 and IgG2 in sera and to IgG and IgA antibodies in BALF at 21 and 28 dpi. Different superscripts within a column indicate significant differences among days post-inoculation (p<0.05).
