|16S rRNA Seq.:|
|Taxonomy/phylogeny:||Five species have been described within genus Avibacterium, which are relatively close to members of the genus Gallibacterium.|
|Comment:||Cultivated with advantage on hematin agar and by the use of X- and V-factor, diagnosis by PCR. Common among non-commercial domestic chickens in Sweden.|
