of the disease intermittent attacks Of
fever will usually be a feature.
As has already been stated. the
natural mode OF infection is usually
by sexual contact. SO that the disease
is practically limited to stations and
brood mares. When gcldings and
animals not. used for breeding con-
tract the disease, its occurrence must
be explained by the possibility Of the
hands OF attendants or infected rags
or sponges transmitting the Infection.
Transmission by means of blood
sucking insects Of parasites is also
a possibility and while not definitely
proven must not be lost sight or.
Symptoms.
The series Of symptoms presented
by the dourine infected horse can be
conviently divided into two stages.
Those Of the first stage make their
appearance between a, few days and
several months after actual exposure
to infection. The initial symptoms
may even remain entirely unnoticed
as they occasionally merely consist
OF slight attacks of fever,
In stations, the disease commonly
begins with a doughy. painless swell
ing of the sheath. which to a greater
or less extent may involve the parts
adjacent thereto. The penis likewise
becomes swollen and may even be-
come quite painful. The mucosa OF
the urethra and the external parts
may show yellow-reddish nodules of
usually less than pea size. They may
occur isolated or in groups. Within
from 70 to SO hours, those nodules
break down and are changed to round.
fat ulcers. In course of time those
ulcers heal, round, white patches in
dicating the place where they former
ly were to be found. In a certain per-
centage of the cases. however. heal
ing does not take. place so readily.
The affected parts are frequently irri-
tated as is shown by an increased ten
dency to void urine. etc .
In mares the earliest visible symr
toms of the disease are puffy swell
ings of the vulva, redness and inflam'
matory swelling Of the vaginal mu'
cosa as we'll as a certain degree OF
discharge from this organ.
The external genitals and the skin
in their immediate vicinity may show
light coloreQ areas. The affected
parts also present the nodules, the
ulcers resulting from their breaking
down and the light colored areas oc-
casioned by the healing of the latter.
Along with the nodules and ulcers,
small blisters may also be found.
Occasionally, the ulcers show more
Of a malignant character and healing
takes place but slowly leaving round
smooth scars. In the more severe
cases, the vaginal discharge becomes
more profuse and from a muco-puru'
lent character it changes to a rory
purulent and even more or less
hemorrhagic nature. In such cases
the external genitals and the tail pe-
comes coated with a nasty scab. while
the swelling extends to the udder, the
abdomen and the legs. During the
development of all these LESSONS the
animals are apt to show a c%onsidera-
BILE amount of irritation of the various
organs involved. .
While the symptoms described ar"
typical of dourine. it must not be for
gotten that they may be slight as to
escape attention altogether. ,
There even is evidence tina animals
may be infected without showing any.
thing wrong whatever.
Later Stage Of Dourine.
A few weeks after the symptoms
described have somewhat improved.
the phenomena peculiar TO the later
stage of the disease may be watched
for.
The later symptoms especially per-
tain to the skin of the nervous sys'
tenn.
In connection with the former, es-
pecially where it covers the Group,
the sides Of the chest, the shoulders.
the neck aside from various other
parts Of the body, there occur round
or ovoid swollen patches
They have diameters ranging from
one to six inches and are typical be-
cause of their contour being marked
by a ring about one inch in width, on
which the hair IS more or less staring
and irregularly erected. With this
ring the hair-coat lies in the ordinary
manner. 4..
Some OF the patches or plaques, as
they are occasionally called. are 1arg.
