Isolation of Bordetella avium from poultry.

Four Australian isolates of Gram-negative nonfermentative bacteria obtained from poultry were compared with reference strains of Bordetella avium, Bordetella bronchiseptica and Alcaligenes faecalis. The Australian isolates were identified as Bordetella avium. A routine procedure for the identification of this recently recognised poultry pathogen is described.
