A study of lung lesions in asymptomatic rabbits naturally infected with B. bronchiseptica
A histological study of lungs performed in 40 rabbits carrying a naturally acquired subclinical B. bronchiseptica infection revealed chronic inﬂammatory pulmonary lesions in 38 rabbits, B. bronchiseptica was the only agent consistently isolated from lungs. Pasteurella spp. was not isolated from any animal. B. bronchiseptica infected rabbits frequently displayed changes characterized by a simultaneous occurrence of focal chronic interstitial pneumonia, vascular and perivascular inﬁltration of monocytes and lymphoid cells, and inﬂammation ofbronchi and bronchioli.
