Bordetella pertussis stain (Gram-negative, coccobacilli, diplococci arrangement), growth on Bordet-Gengou agar or BCYE plate with added cephalosporin to select for the organism, which shows mercury drop-like colonies. "B. pertussis" can also be detected by PCR, which is more sensitive than culture. The primers used for PCR usually target the transposable elements IS481 and IS1001. Several diagnostic tests are available, especially ELISA kits. These are designed to detect FHA and/or PT antibodies of IgG, IgA, or IgM. Some kits use a combination of antigens which lead to a higher sensitivity, but might also make the interpretation of the results harder, since one cannot
Aleutian disease Aleutian disease Aleutian disease, also known as mink plasmacytosis, is a disease which causes spontaneous abortion and death in minks and ferrets. It is caused by "Carnivore amdoparvovirus 1" (also known as "Aleution disease virus", ADV), a highly contagious parvovirus in the genus "Amdoparvovirus". The virus has been found as a natural infection in the "Mustelidae" family within mink, ferrets, otters, polecats, stone and pine martens and within other varying carnivores such as skunks, genets, foxes and raccoons. This is most commonly explained as because they all share resources and habitats. Aleutian Disease was first recognized in ranch-raised mink in
