Lungs showing Mycoplasma-like lesions at abattoir (a, c and e) and their corresponding microscopic lesions (b, d and f, respectively). b: Peribronchiolar lymphoid clumps of cells of varying degrees of development infiltrating the lamina propria of the bronchioles to a differing extent (BALT hyperplasia) (arrows). Bronchointerstitial pneumonia. d: Exudate inside bronchi, bronchioles and alveoli, predominantly composed of degenerated neutrophils (asterisks). Suppurative bronchopneumonia. f: Mixed pattern of lesions showing both types of pneumonia described in pictures b and d (arrows and asterisks). Bronchointerstitial pneumonia + suppurative bronchopneumonia
