There is also a journal case report of an individual case in a MS, for which I do not have the pedigree. The breeder's brother owned the dog and he contacted me after I spoke with the doctor who originally wrote the report. At the time I turned over copies of all my materials to AU for their work, I was aware of 9 confirmed cases of M avium in MS and had the pedigrees for 7 of them. There is very strong suggestion of an inherited immune system dysfunction based on linear and genetic pedigree anaylsis. Whether it is inherited through a simple recessive or polygenic form is unclear, although one pedigree, of the 3 littermates, demomstrates enough genetic variance on the sire's side to indicate a simple recessive.
Sexes are about equally represented.
According to a researcher I spoke with, it has been considered a recessive in the Basset Hound work that was done in the last 10 years. Journal of the American Veterinary Medical Assoc. With the permission of Dr. Clint Lothrop I am posting this letter in its entirety, concerning the research he is conducting pertaining to Avian TB Infecton in Miniature Schnauzers. There are an estimated 2-3 million deaths in people from tuberculosis each year, and 10 million new cases of active disease. Tuberculosis is primarily transmitted through aerosol droplets, but it can also be transmitted through milk and infected meat.
