The stable attendants serve as one of the most common carriers of the
virus. Dried or fresh discharges are collected from the infected animals
in cleaning, harnessing, feeding, and by means of the hands, clothing,
the teeth of the currycomb, the sponge, the bridle, and the halter, and
are thus carried to other animals.

An animal affected with chronic glanders in a latent form is moved from
one part of the stable to another, or works hitched with one horse and
then with another, and may be an active agent in the spreading of the
disease without the cause being recognized.

Glanders is found frequently in the most insidious forms, and we
recognize that it can exist without being apparent; that is, it may
affect a horse for a long period without showing any symptoms that will
allow even the most experienced veterinarian to make a diagnosis. An old
gray mare belonging to a tavern keeper was reserved for family use with
good care and light work for a period of eight years, during which time
other horses in the tavern stable were from time to time affected with
glanders without an apparent cause. The mare, whose only trouble was an
apparent attack of heaves, was sold to a huckster who placed her at hard
work. Want of feed and overwork and exposure rapidly developed a case of
acute glanders, from which the animal died, and at the autopsy were
found the lesions of an acute pneumonia of glanders grafted on chronic
lesions, consisting of old nodules which had undoubtedly existed for
years.

In a case that once came under the care of the writer, a coach horse was
examined for soundness and passed as sound by a prominent veterinarian,
who a few months afterwards treated the horse for a skin eruption from
which it recovered. Twelve months afterwards it came into the hands of
the writer, hidebound, with a slight cough and a slight eruption of the
skin, which was attributed to clipping and the rubbing of the harness,
but which had nothing suspicious in its character. The horse was placed
on tonics and put to regular light driving. In six weeks it developed a
bronchitis without having been specially exposed, and in two days this
trouble was followed by a lobular pneumonia and the breaking of an
abscess in the right lung. Farcy buds developed on the surface of the
body and the animal died. The autopsy showed the existence of a number
of old glanderous nodules in the lungs which must have existed previous
to purchase, more than a
