Abstract
A total of 24 Gram negative non fermentative bacteria obtained from poultry were compared with reference strains of Bordetella avium, Alcaligenes faecalis, Bordetella bronchiseptica and a Bordetella aw'um-like organism. Thirteen isolates were identified as B. avium and 11 were identified as B. avium-like. A commercial microidentification kit (the API20NE) did not identify the field isolates but did separate them correctly into the 2 groups. A practical identification scheme, suitable for diagnostic laboratories, is proposed for these organisms. The available clinical histories suggest that B. avium is associated with upper respiratory tract disease in turkeys. Aust Vet J64: 239–240
