Under this name Glass describes an affection, milder than the usual
distemper, but showing similar lesions and demanding an equivalent
treatment. It is not self-limiting the same patient having suffered
twice in the same year (an occurrence which is occasionally seen in
distemper.) The incubation is 3 to 5 days. Diarrhœa is invariably
present from the first, and the fæces slimy and at the end of a week
slightly bloody. The affection is characterized by the predominance of
the digestive disorder, the absence of skin eruption, the free shedding
of the hair in long coated animals, the ulceration of the gums, tongue
and lips, and the low mortality.
Bacteriological research must be invoked to determine whether this is
only a form of distemper or if it is one of a group of diseases which
have hitherto been known by that name.
