Abstract

Thirty-eight cases were identified in which a nonfermentative, gram-negative, rod-shaped bacterium was isolated from the respiratory system of turkeys and chickens. Cases were submitted from various parts of the country. Preliminary assessment of phenotypic characteristics indicated this bacterium was different from common pathogenic or opportunistic bacteria isolated from the avian respiratory tract. Most cases reported a history of respiratory distress and/or increased flock mortality. Lesions seen in infected birds included tracheitis and pneumonia, which correlate with the sites of isolation. Sixty-one percent of the isolations were made from the trachea and 25% from the lung. Age of infected birds ranged from 35 to 315 days in turkeys and 53 days to 3 yr in chickens. In most instances (90%), other bacteria were also isolated from affected sites. The significance of this organism in respiratory disease in birds is unknown.
