Hi, I have some info from a book that many don't have (to my knowledge) on Aleutian Disease (Plasmacytosis). The book is "Diseases of the exotic animals medical and surgical management" by Wallach Boever. "The name Aleutian is derived from the original description of the diseased mink, which were double recessive for the gunmetal color phase (Aleutian color)." Here is how it got its name. It has also been brought to my attention by a few people that were told there are a lot of false positives on ferrets tested. This is how the book said it should be tested for. "When checked by electrophoretic methods, the IAT is 95% accurate. The reagent for the IAT is made with 2gm iodine crystals, 4gm potassium iodide, and 30ml distilled water. To perform the IAT, blood is collected in a nonheparinized capillary tube and centrifuged. The serum is mixed on a glass slide with an applicator stick. Clumping or precipitation within a few seconds indicates a positive reaction." Well, If the need does arrive on this side of the states (west), I am planning a move to a new home soon and in the search will look for a place to house my regular rescues and one that has the ability to house in a sperate building ferrets ill with this so they may live there life out instead of being euth. Of course the strictest quar of these ferrets will be maintained as anyone who knows me can tell you I am very cautious about the spreading of illnesses. hope this time finds many of you well.
