Gross turbinate, nasal septum, and lung lesion of piglets 14 days after P. multocida challenge. Piglets were immunized i.m. at week 0 and boosted at 2 weeks. All piglets were challenged intranasally with 1 × 108 CFU/mL P. multocida serotype A 4 weeks after primary immunization. Dissection of unvaccinated piglets is shown for comparison. Characteristic gross lesions of P. multocida infection, including turbinate atrophy, nasal distortion and pulmonary lesions that exhibited extensive interstitial pneumonia, were observed.
