North Dakota Vetrinary Diagnostic Lab

Anthrax diagnosed in Sioux County herd

Thursday morning, September 21, the North Dakota Veterinary Diagnostic Laboratory confirmed the presence of Bacillus anthracis, the causative agent of Anthrax, in samples submitted from a Sioux County herd.  

The affected herd had recently experienced higher than normal mortality over the preceding weeks. 

Samples were referred to the laboratory from an astute, Mandan, ND veterinarian, who after traveling to the premise suspected the diagnosis after evaluating the history in conjunction with the gross pathologic features of two dead cattle. 

Submitted specimens were positive by PCR and confirmed by bacteriophage specific culture.   

For more information on Anthrax, please consult your primary herd veterinarian and see our test page.

Additional publications on Anthrax are available from the NDSU extension service
