The testing Of cattle for tuhercu-
iosis in Murray county has precipitae
ted such an avalanche Of discussi65{
and argument on the subject that 8
business man of Slaytcn III order 70
satisfy his own mind as to the danger
of infection from tubercular cattle,
wrote to Dr.. William J. Mayo, of
Rochester, for his opinion. DR.. Mayo
wrote back and explained that as his
brother, DIR. Charles Mayo, had given
the subject more attention and was
better fitted to answer the letter that
| it had been referred to him. This
was followed few days later by
letter from DIR. Charles Mayo giving
his opinion. Information that is so
important to the human race and COM
ing from such eminent authority
should be given to the public, so per-
mission was obtained from DIR. Mayo
| to print his letter which follows:
August First, 1925.
Mr.. j. X. Campbell, Manager,
Slayton Farmers Shipping Associa-
! ton,
Slayton, Minnesota.
| My dear Mr.. Campbell
My brother has referred your letter
of July 25th to me concerning tuber-
| culosis in cattle and am glad to
learn of the great reduction in re-
actors in Murray county; it is fine
showing.
There is little variation in the APP
pearance of tuberculosis found in
| chickens (Avian type), in cattle (Bo-
vine type) and in the human. 1t has
long been known that hogs will be-
come infected by running in the yard
and feeding with fattening cattle, pro-
viding any of the cattle are tubercu-
lous. 1t is impossible to transplant
Bovine tuberculosis to chickens, yet
i if chickens run in the yard with tu-
berculous cattle few of them will
finally become inoculated from the
many billions inoculated from the
many billions of germs and develop
Avian type of tuberculosis, which will
rapidly spread in the flock; this is
also true of turkeys. Tuberculosis ir
fowls affects the intestines and the
liver, in cattle the glands, intestines
rarely the udder, frequently the live,
and in advanced cases the lungs. With
such an enormous number of germs
slight variation may occur which
can inoculate other types of ANNA
life.
The general estimate is that from
to per cent of diseased tonsils ir
children are tuberculous. Tuberculal
tonsils, tuberclar glands in the mech
and tuberculosis of the intestines anC
mesentris glands of the intestines are
in the majority of cases attributed to
the Bovine type of tuberculosis, the
germs of which are thrown off in-the
milk of dairy cattle thus affected, even
without tuberculosis of the udder
which is rare condition. Tubefcu-
losis of the bones, joints and glands is
now uncommon in children in the
cities where the milk supply is care
fully protected by the testing of the
dairy cows for tuberculosis or the
pasteurizing of all of the milk which
destroys the main disease organisms
Such diseases are now far more COM
mon in children on the farm, as no bne
on the farm is interested in looking
after these cattle unless they are en-
gagged in dairying.
The meat is used from cattle af-
| fected with tuberculosis, unless the
disease is very far advanced. Only
approximately 10 per cent are con-
sidered so bad that they go to the
rendering plant for soap.
Only the worst and chon:c cases of
tuberculosis with but little fever would
be missed in a tuberculin test. This
is true in testing humans where the
extent of the disease is so great that
there is little or no reaction to the
small amount of test material, tuber-
culin, used, yet the disease can readi-
ly be found by the examining
physician and shows in the x-ray.
Early cases, suspicious of disease,
show action in approximately 100 per
cent; this unfortunately lets some of
the worst diseased cattle remain in
the herd, continually inoculating
others. High class dairy cattle, eat
/ ing large amount of food to convert
into milk are allowed a fermentation
heat temperature of one or two
degrees during periods of the day
