[Immunohistology as a reliable and efficient method for the diagnosis of BVDV infections]

Persistent infection with the Bovine Viral Diarrhea/ Mucosal Disease Virus (BVDV) can be detected using immunohistological methods. The experiments show that the LSAB (Labeled Streptavidin Biotin) peroxidase method is suitable to detect the BVDV in cryostat sections of unfixed tissue. For the diagnostic work up in living animals, skin biopsies give reliable results. In dead animals, organs such as thyroid gland, skin, mucosa of the mouth, esophagus and abomasum are well suitable for immunohistological BVDV detection.
