[Pigeon coryza--ornithosis--pigeon breeder's lung]

Abstract

The published informations on the entities pigeon coryza and ornithosis are reviewed. On the basis of own experiences and experimental data obtained in the Landesveterinäruntersuchungsamt Koblenz, pigeon coryza apparently is a symptom rather than a clearly defined disease. Finally pigeon breeder's lung is discussed in front of the background of own observations and recommendations to be of allergic origin.
