Turkey coryza: lack of correlation between plasmids and pathogenicity of Bordetella avium.
Plasmids were removed from pathogenic Bordetella avium using a variety of treatments. The plasmid-cure rates depended on the treatment and isolate. Pathogenicity of B. avium in turkey poults was not altered by removal of plasmids.
