308 OTHER GERM DISEASES 
septicus, B. suisepticus, etc., but the most careful study fails to 
show differences sufficient to warrant their separation, and the 
name B. pleurisepticus has been suggested as indicating its relation 
to its many hosts. While it attacks many animals it is, so far as 
known, harmless to man. It produces a type of disease quite 
similar to the forms of blood-poisoning which have been, in medical 
practice, called septicemia. It is extremely fatal to some animals, 
fowls and rabbits succumbing to its action with extreme rapidity 
and with almost absolute certainty. Among the larger animals 
its course is not necessarily so fatal, but in all those referred to 
above the disease is a serious one and almost always fatal. When 
attacking the hog it produces one form of swine plague, this being 
the type of the disease most commonly found among domestic 
animals, and the one which will usually be most interesting to the 
agriculturist. 
Glanders. Farcy. Rotzbacillus (B. mallei)——This disease, 
well known among agriculturists, occurs not infrequently as a 
normal infection in the horse and in the ass. It is characterized 
by the appearance of ulcers in the nasal membranes, by enlarged 
submaxillary lymphatics, which may turn into open discharging 
ulcers. Later the lymphatics of the whole body may become 
tumor-like swellings. Other parts of the body may eventually 
beaffected. ‘The secretions from the various ulcers are found to be 
decidedly infectious, and it is through these ulcers that the disease 
is commonly distributed. It occurs in an acute form and in a 
chronic form; the latter, chiefly in the skin, receiving the name 
of farcy, the former, chiefly in the lungs and nasal passages, more 
commonly known as glanders. It occurs spontaneously only in 
horses and asses, and causes great losses in nearly all localities. 
It may occur by accidental or artificial infection in many other 
animals. It occurs occasionally in men who have become acci- 
dentally inoculated in the treatment of horses suffering from the 
disease, and when it does occur in man it is an extremely fatal 
disease, almost always resulting in death.
