DR.. J. M. Wilson,
Douglas, Wyoming.
Sir:-As a result of several investi-
cations Of the disease affecting the
mouths and legs of sheep which is
more or less prevalent in certain dis
tricts of Wyoming a diagnosis of lip
and leg liberation (necrobacillosis)
has been made.
In so far as the name to be applied
to this affection is concerned, it is
quite imma terial SO long as such a
name is distinctive and does not con-
fuse the disease with other affections
of an entirely different nature. For
instance, it is very important that
the name F'foot and mouth disease"
should not be given to this affection
because the two diseases are totally
unlike in symptoms, are caused by
different specific agents, and the for
mer is so highly infectious that every
outbreak which has appeared on
American soil has been quickly stamp
ed out before it became widespread.
Furthermore, the Lucrative condition
which affects the lips and legs of
sheep does not spread from animal to
animal in epizootic form like foot and
mouth disease, but certain sheds,
feed lots, corrals or pastures becomes
infected with the germs causing the
disease which enters the tissues when
the mouth or leg is injured by briars,
stubble, rough forage, etc. and set
up disease. During the winter when
snow is on the ground and the weather
so cold that the surface of the snow
becomes hard and crusted, thus max
ing grazing very difficult, the disease
may spread very rapidly and easily,
owing to the numerous scratches re-
ceived upon the nose and feet becom-
ing infected with the blood and bits
of scab which drop from the affect
ed sheep. Lip and leg liberation is
caused by the necrosis bacillus and as
the skin of the legs, muzzles and lips
are involved in many cases, the name
of necrotic dermatitis necrotic infa-
nation of the skim has been applied.
1t quite frequently happens that the
ulcers and sores on the outside Of the
lips extend into the mucous membrane
lining the inside Of the lips as
we'll as to other parts of the mouth
or LESSONS of the mouth may occur
through licking the ulcers on the legs,
which accounts for the disease being
termed necrotic stomatitis (necrotic
inflammation of the mouth. 1t will be
observed that the important things
to recognize are tina nature and cause
of the disease, and in this connection
it may be stated that all the differ
ing manifestations of the infections
by this one bacillus necrosis baeillus) |
are often brought together under the
term necrobacillosis. Other names
which have been given the disease are
acute dermatitis in New Zealand, |
impetigo labialis in Canada, or crusto
labialis and contagious pustular der
mathis in England and Scotland, and |
teigmani and maulgrund in Germany. !
This disease also exists in the West
Indies, New Mexico, Oregon, Ksnsas,,
Montana, Virginia, Maryland, and
other sections of the United
states.
The LESSONS of the early stage US
ually appear as an acute inflammation
Of the skin on the outside of the lips.
This pimple-like formation is attend /
ed with much infamatory swelling
with decided tendency toward the
formation of pustules. They dry and
form crusts Of dark grayish color
and Of a fungoid appearance. The
growths extend rapidly and become in
the course of a few days continent,
forming large diffused scab which is
found when removed to cover an Ill
