rses and to the stable attendants is so
great, that no animal which has once been affected with the disease
should be allowed to live unless repeated mallein tests have shown him
to have become free from taint of glanders.

In all civilized countries, with the exception of some of the States in
the United States, the laws are most stringent regarding the prompt
declaration on the part of the owner and attending veterinarian at the
first suspicion of a case of glanders, and they allow indemnity for the
animal. When this is done, in all cases the animal is destroyed and the
articles with which it has been in contact are thoroughly disinfected.
When the attendants have attempted to hide the presence of the disease
in a community, punishment is meted out to the owner, attending
veterinarian, or other responsible parties. Several States have passed
excellent laws in regard to glanders, but these laws are not always
carried out with the rigidity with which they should be.

SPOROTRICHOSIS (MYCOTIC LYMPHANGITIS).

By JOHN R. MOHLER, V. M. D., _Assistant Chief, Bureau of Animal
Industry_.

This disease has previously been known in this country as epizootic
lymphangitis, or pseudo-farcy. It is a chronic, contagious disease,
particularly of equines, caused by a specific organism, the
_Sporotrichum schenckii_, and characterized by a suppurative
inflammation of the subcutaneous lymph vessels and the neighboring lymph
glands. Owing to the fact that this affection does not spread as an
epizootic and that its causal factor is a fungus, the name
sporotrichosis has been suggested.

The disease in man was first described by Schenck and by Beurmann and
Gougerot. Carougeau observed its occurrence among horses and mules in
Madagascar, while in the United States it was first observed by Pearson
in Pennsylvania in 1907, although it is probable that it had existed for
many years in various parts of this country. Page and Frothingham were
first to recognize its mycotic nature in the United States. More
recently Meyer has also made valuable contributions with regard to the
existence of this affection. Its presence has been definitely
established in Ohio, Iowa, California, and North Dakota, and there is a
probability of its existence in Indiana and several Western States.

_Bacteriology._--The sporotrichum is 2 microns thick, cylindrical and
segmented, having more or less branching threads, which bear spores at
the end. In the pus they oc
