Diagnosis and Testing

Diagnostic Testing in Wildlife

The heads and/or lungs of deer submitted for necropsy are examined by Michigan Dept. of Natural Resources Wildlife Disease Lab personnel. The parotid, submandibular, and medial retropharyngeal lymph nodes will be collected if visual lesions are present. Histopathology using routine hematoxylin and eosin and acid-fast staining is done at MSU's Diagnostic Center for Population and Animal Health. Chilled portions of lymph nodes are shipped to the Michigan Department of Health and Human Services Tuberculosis Laboratory for mycobacterial culture and identification.
