More Information
Summary:Pathological and bacteriological examinations were conducted on a bovine mastitis caused by Nocardia Macroscopically, the cut surface was greyish white in color, and general edema with hemorrhage being observed. Histopathologically, necrosis of the mammary gland was seen, and exudate cells and tissue debris filled the alveoli. The Grocott's stain revealed numerous fungal threads. Bacteriologicaly, white and dry colonies were isolated in pure culture from the mammary lesions. The organism was identified as Nocardia asteroids from the biological characteristics. From these observations, this case was diagnosed as a gangrenous mastitis caused by N. asteroides.
