Clearance of bacteria in turkeys with Bordetella avium-induced tracheitis.
Quantitative clearance of aerosolized Escherichia coli from the trachea, lung, and air sacs was measured in turkeys infected with Bordetella avium. Clearance of E. coli in turkeys with B. avium-induced tracheitis was minimally affected early in infection. Sixteen to 23 days after infection with B. avium, sporadic, mild depressions in clearance of E. coli were observed in the tracheas, which had large areas of deciliated tracheal epithelium or replacement of normal epithelium by immature hyperplastic epithelium or metaplastic squamous epithelium. Clearance of E. coli from the lung and air sacs was minimally affected in turkeys infected with B. avium.
