Bordetella bronchiseptica produced pneumonia was studied in young piglets. At the beginning of the experiment, 30 artificially reared 3-day-old piglets were divided into two groups: group A – uninfected piglets, control group (n=10) and group B – piglets infected with B bronchiseptica, experimental group (n=20). The B. bronchiseptica infection (106 CFU/ml) was performed on day 4. In Group B, clinical signs including mild serous nasal discharge, sneezing, panting, and hoarseness appeared from day 4. Computed tomography (CT) performed on day 16 demonstrated lung lesions attributable to colonisation by B. bronchiseptica in the infected pigs. The gross pathological findings confirmed the results obtained by CT.
