- We generally see these distinctive 1 – 2 mm caseonecrotic lesions in longer-standing polymicrobial pneumonias, often non-responsive to several rounds of antibiotic treatment. These are positive for M. bovis by PCR. Margins of necrotic lesions stain strongly for the agent on immunohistochemistry. Caswell JL, Archambault M: 2007, Mycoplasma bovis pneumonia in cattle.
