Pasteurella pneumonia: report of a case and review of the literature.

A case of pneumonia due to Pasturella ureae was encountered in a 57-year-old man who developed bilateral pulmonary infiltrates and respiratory insufficiency while convalescing in the hospital from a hip fracture and multiple rib fractures. Cultures of his sputum grew an essentially pure growth of Pasturella ureae. This organism, a small gram-negative rod, could be differentiated from the other Pasteurella species by its ability to hydrolyze urea and failure to produce indole. The literature on Pasteurella infections is briefly reviewed, and the recent taxonomic revisions of the genus Pasteurella are discussed.
