Bordetella avium causes respiratory tract infections in poultry (coryza or rhinotracheitis). B. hinzii is the name recently given to organisms previously referred to as B. avium-like or Alcaligenes faecalis type II. Although these latter organisms have been isolated from diseased birds, there is little evidence that they are pathogenic. Four isolations of B. hinzii from humans have been reported, including isolations from blood of an AIDS patient and sputum of a patient with cystic fibrosis. The objective of the experiments reported herein was to determine if DNA fingerprinting could be utilized to distinguish among B. avium and B. hinzii strains representing isolates from the United States, South Africa, and Germany. Digestion of chromosomal DNA with twenty restriction enzymes was carried out for DNA fingerprint analysis. The digested DNA fragments were electrophoresed in agarose gels and stained with ethidium bromide. We found that restriction enzyme digestion with Hinf I produced fingerprin patterns in the 2.0- to 10-kb range, and readily distinguished B. avium isolates from B. hinzii isolates. Furthermore, Hinf I digestion of chromosomal DNA from B. avium strains produced eight distinct fingerprint profiles.
