Mastitis in the lactating mink female (Mustela vison S.) and the development of "greasy kits".
"Greasy kits" is the result of a multifactorial disease complex with few known definitive aetiological factors. Mastitis has been hypothesized as a triggering factor although classical clinical signs of mastitis (rubor, tumor, dolor, calor) are rarely seen in lactating Danish mink females. In this study we sacrificed 2 groups of lactating mink females with a total of 78 mammary glands at day 19-30 after giving birth. The first group had raised normal mink kits while the other group had suffered severe attacks of greasy kits. We found no clinical or histopathological evidence of mastitis but isolated streptococci and staphylococci from 2 mammary glands in females raising greasy kits. These glands showed no clinical or histological signs of inflammation attributable to bacteria and we conclude that mastitis is not necessary for the generation of greasy kits.
