certain chemicals Infection occurs
Cd By breathing the germs; (2) By
swallowing the germs. 90 By theil
entrance through cut or wound. The
! three general sources of infection are

consumptives or other tuberculous
matter, either breathed Or swallowed;
! (2) Contact with tuberculous material
or people; (3) The meat and milk of
tuberculous animals.
The bacillus tuberculosis is the sole
cause of the disease, but there are
conditions SO favorable to it's develop
ment that they are well termed ac-
cessory causes, although strictly
speaking they are not casual.
The symptoms of bovine tuberculo-
sis are more obscure than those of hu-
man disease, and often battle detec-
ton. Any attempt to describe them
would probably prove misleading
rather than instructive.
Wherever the germs locate in the
body they irritate the tissue, forming
round nodular masses. These newly
formed tubercles are usually soft and
red. In chronic cases they become
cheesy, limy, ,and disintegrate and run
together, forming yellowish, Gaseous,
pus- containing masses of various siz-
es imbedded in the diseased organs
The lungs, Innings of the chest and alb
domen, the lymphatic glands and bow
els are most often diseased Some.
times the tubercles are too small for
the naked eye to see.
Tuberculin is made from pure cul-
lures Growth separate from other
germs) of the tubercle bacillus, con-
centrated, sterilized (to kill all germ
life) and filtered. 1t contains the
chemical poisons created by the life
functions of the germs. Although
failure as a cure for tuberculosis, it
has been successfully used to detect
it's existence in cattle. If a small
quantity is injected into tuberculous
animal it will produce fever, but, if
the animal is healthy and it is prop
erly used there should be no rise of
An increase of two de-
grees above the normal temperature
after injection is ground for suspicion.
The tuberclin test is not infallib1e. I
Mistakes have been made in it's use, |
and it has sometimes failed in careful |
hands. 1t is, however, much more re-
liable than any other known means of
diagnosis. If properly made and used,
t can not cause tuberculosis.
Both human and bovine tuberculo-
lis are infectious. Human tuberculo-
lis affects the lower animals, and bo-
vine tuberculosis affects man. The
after has never been directly proved,
'ut many cases of accidental infection
AVE demonstrated its possibility. It
las been claimed that tuberculosis
oeS not exist where there are no cat
lie, and that tuberculous infection
7as originally of bovine origin. Ex-
eriments have shown that the dis
ase- producing germ may be present
4 the milk whether the udder is af-
ected Or not. If milk is sterilized by
eat, or ''pasteurized,' - it may be con-
dered safe to use. 1T has recently ]
cen claimed that, because of the al
,ged presence of tuberclin in tuber-
llous milk, even though sterilized,
lere is danger to its consumers of
resent. It is not advisable to attempt
cure bovine tuberculosis.
Both human and bovine tuberculo 7
S are preventable, and the means
hich may be taken to prevent it's
,read are: % Official inspection of
title, meat and milk; (2) The de-
ruction or disinfection of human
little; CO Careful disinfection of
aces occupied by tuberculous men or =
limals. The stock owner, so far as =
,ssible, should keep his cattle under
salthy conditions, should keep each
limal in its own stanchion, should
0late suspected animals, should buy
should exclude human and y,
imal consumptives from the barn,
ould test newly admitted animals,
d, if he finds the disease, should
IL, bury or burn the diseased ami
ais, disinfect the premises and test
@ rest of the herd.
