Consolidating bacterial pneumonia
This is an NCLEX style exam that will challenge your knowledge to help you be more prepared for the test.All questions are shown in random and the results, answers and rationales (if any) will only be given after you’ve finished the quiz.At necropsy, testing whether lung tissue sinks (pneumonia) or floats (normal) remains a useful screening test.In acute cases, cultures obtained from tracheal swabs or washes or from lung tissue or associated lymph nodes are diagnostic.
In calves, alveolar macrophage function is impaired after viral pneumonia.
The lungs are heavy, swollen, and purple-red in peracute cases, and the airways contain blood-stained froth.
Cases of longer duration show anteroventral consolidation and fibrinous pleurisy.
Control and prevention lies with correction of the predisposing factors whenever practical.
Prevention of pasteurellosis is best attempted using vaccines incorporating iron-regulated proteins; because these proteins are antigenically similar, they confer cross-protection against other serotypes.
