All carnivora are liable to contract glanders by eating the flesh of
glandered horses, asses and mules, and this has been noted especially in
menageries. _Lions_, _tigers_, _bears_ and _wolves_, have shown the
ulcerous lesions in the nose, and the nodules in the lungs, spleen,
liver, kidneys and elsewhere. The carcass of the diseased horse is,
however, often devoured without evil result, and even when the carnivora
become affected the disease is not always fatal.
In the _dog_, experimental glanders has been closely studied by many
observers. Casual glanders has been contracted by living with the
glandered horse; by licking his nasal or other discharges, and by eating
his flesh. The disease has also been conveyed from dog to dog by licking
each other. In many cases even inoculated glanders produces only a local
ulcerous inflammatory lesion with or without hard swelling of the
adjacent lymphatics, and engorgement of the lymph glands. After a rather
tardy granulation and cicatrisation, the symptoms subside and the animal
is restored to health. Yet such benignity does not depend on any
lessened virulence of the bacillus, for an inoculation of the discharges
on the ass produces acute and fatal glanders.
