On a tangent, ADV has been detected in the mammary glands and breast milk
of mink.
JR Gorham, JB Henson, TB Crawford, and GA Padgett, "Epizootiology of
Aleutian Disease," 1976
The researchers above did *not* detect ADV in colostrum during their
trials, but its presence was reported to them thru personal communication
with J Haagsma, a Dutch scientist concurrently researching ADV in mink. All
of the researchers above agreed that vertical transmission was most likely
placental as ADV was detected in stillborn kits, and because fetal material
injected into non-infected mink caused AD immune response in 32 (60%) of
the hosts.
Note: On Aug 18 I offered that lymphocytes were replaced as often as most
cells, and was corrected by a friend and *human* hematopathologist (quoted
with permission as long as it's understood the below applies to humans, not
necessarily ferrets):
"There are different types of lymphocytes; B-cells, T-cells, natural
killer cells, etc. Some are short lived while others such as memory
B-cells live for many years (decades)."
