Mink enteritis virus (MEV) is a highly contagious viral pathogen that primarily affects minks, causing a severe and often fatal disease known as mink enteritis. It belongs to the viral family Parvoviridae and the genus Parvovirus. MEV is a single-stranded DNA virus, characterized by its small size and non-enveloped structure.
MEV primarily targets the gastrointestinal tract of minks, causing inflammation and damage to the intestinal lining. The virus is transmitted through direct contact with infected minks or their feces, making it highly contagious within mink populations. It can also be transmitted through contaminated feed, water, or fomites.
Clinical signs of MEV infection include diarrhea, vomiting, dehydration, weight loss, and ultimately death. Infected minks may also exhibit a reduced appetite and lethargy. The severity of the disease can vary, with some minks showing only mild symptoms or remaining asymptomatic.
Due to its high contagiousness and potential for significant economic losses in the fur industry, mink enteritis virus is a significant concern for mink farmers. Vaccines have been developed to help prevent infection and control the spread of MEV within mink populations. Strict biosecurity measures, such as appropriate sanitation practices and quarantine protocols, are crucial in preventing the introduction and spread of MEV in mink farms.
Overall, mink enteritis virus is a virulent and economically important virus that affects minks, leading to a highly contagious and often fatal disease.
