Abstract
BackgroundInfectious skin disorders are not uncommon in mink. Such disorders are important as they have a negative impact on animal health and welfare as well as on the quality and value of the fur. This study presents the isolation of Arcanobacterium phocae from mink with severe skin lesions and other pathological conditions, and from wild seals and otters.ResultsIn 2015, A. phocae was isolated for the first time in Denmark from outbreaks of dermatitis in mink farms. The outbreaks affected at least 12 farms. Originating from these 12 farms, 23 animals cultured positive for A. phocae. The main clinical findings were necrotizing pododermatitis or dermatitis located to other body sites, such as the lumbar and cervical regions. A. phocae could be isolated from skin lesions and in nine animals also from liver, spleen and lung, indicating a systemic spread. The bacterium was also, for the first time in Denmark, detected in dead seals (n = 9) (lungs, throat or wounds) and otters (n = 2) (throat and foot).ConclusionsAn infectious skin disorder in mink associated with A. phocae has started to occur in Danish farmed mink. The origin of the infection has not been identified and it is still not clear what the pathogenesis or the port of entry for A. phocae infections are.

Gross pathology and histopathology Detailed information on the pathology of individual mink, seals and otters are available in Additional file 1
The bacterium, A. phocae, originally isolated from lesions and internal organs in seals living in the coastal waters surrounding Scotland [7, 8], has in recent years become an important pathogen in farmed mink in both Europe [15] and Canada [3]
Summary
Infectious skin disorders are not uncommon in mink. Such disorders are important as they have a negative impact on animal health and welfare as well as on the quality and value of the fur. Infectious skin disorders are not uncommon in mink and are of significance to the fur industry. Skin disorders have an impact on animal health and welfare and on the quality and value of the fur. Secondary infections of bite wounds are often associated with bacteria like Staphylococcus delphini and Streptococcus canis [3].
