Some Experiments with Tubercufin1.
An English committee has recently
reported some valuable observations
on tuberculln and tuberculosis Elk
periments were made for the purpose
of determining the effect of repeated
doses of tuberculin and the length or
time after infection before reaction
to tubercu1in takes place For this
purpose apparently healthy animals
were selected and tested with tuber-
culin. If they failed to react they
were inocu1ated with the tubercle
bacillus and tested at intervals after
ward, in order to determine how soon
they would react to tuberculln- one
animal that gave a decided reaction
when tested on October 8 subsequent
1y failed to react, or reacted after
nate1y. For two months it received
large quantities of tubercu1in and en-
tirely ceased to react The animal
was inoculated with tubercle bacilli
on February and reacted to tuber-
culin eight days after incubation
The animal was then treated to large
doses of tuberculin without reaction
When killed on May p no trace or
tuberculous lesion was found except
a casefed and inert tubercle In
mesenteric gland. In other expert
ments it was found that in many
cases reaction to tuberculin did not
occur until from 40 to SO days after
the animals were inoculated with tu-
bercuIosiS- In several cases winch
reacted decidedly on the first test,
complete failure to react was noted
if the test was repeated within a short
time. The experimenters expressed
their belief that repeated injections OF
tuberculin may have some curative
effect or may retard the progress OF
the disease to some extent, and that
the matter is largely Influenced by the
individuality of each animal. A few
animals could not be inoculated with
virulent tuberc1e bacil1i. although
they had not been previously treated
with tuberculin and appeared to be
entirely resistant to tuberculosis.
One Way of Spreading Charlton.
If all danger ended with the ex-
piring breath of charbonous animals,
all would be well, as is perhaps often
thought to be the case by many
stock owners, unfortunately this IS
not So but on the other hand, the
| dead animal is, through its infected
| blood and tissues, the most danger
| Gus source of future Infection An
! outbreak generally starts with one
| dead animal that has caught the IN
| lection from grazing over pasture that
| has been previously contaminated by
| the discharges from a charbonous
! carcass. With the myriads of blood
! sucking flies surcharged with the
/ germ-infected blood of this first vic
| tim, they are now prepared TO start
| the deadly work of inocu1ating healthy
| but susceptible animals. There are
| many other agencies that are capable
/ of transmitting the virus, in fact any
/ thing that can carry charbonous blood
| can do it, but we believe that the
| horsefies, and perhaps other blood
| sucking insects, are more responsible
/ for the extensive spread of this dis
| ease in our state than all other
| agencies combined, which opinion
| will, we think, be borne out by any
| careful observer familiar with this
| plague. But provided there were no
| charbonous carcasses left exposed,
/ then the chief source from which the
| various transmitting agencies pro-
/ cure their deadly freight would not
| exist and necessarily it could not be
| carried. If we were asked our Opin-
| inon as to the most important factors
in producing our periodic outbreaks
/ or epizootics of Charlton in Louis
| lana, we would say, unhesitatingly,
| first, original victims that have been
/ care1essly hauled out and left
| posed. Second, horse-f1ies to convey
| the charbonous blood from the re-
| Gently dead animal to healthy stock.
Mango of the Horse
The horse may be infected with any
| of the three groups of mango para
| sites. With the exception of the sym
| biotic mango, which is usually To-
| Gated about the pastern joints, the
! disease is most commonly seen
the sides of the neck, base of the tail
| or on the inner sides of the limbs.
| The mite is SO small to be easily
| overlooked in making examination
| If the mites are present they may be
| seen by placing pieces of crusts and
scabs on dark paper when the small
