Treatment. Enzootic Spinal Paralysis of the Horse. 697 



is due to defeneration of the intervertebral discs, a condition 

 which frequently improves rapidly without any treatment what- 

 ever In the small animals, electricity may be employed, a large 

 electrode being placed on each side of the spme, and a strong 

 galvanic current passed for thirty minutes. The paralyzed 

 muscles mav ])e stimulated by faradization, or if their sensi- 

 bility to this be lost, a galvanic current may be used But no 

 more is to be expected from electricity than from other meth- 

 ods of stimulating the muscular, nervous and circulatory sys- 



^"^^in cases in which anv of the above treatments are without 

 avail, animals that are fit for food should be sent to the butcher 

 as soon as practicable.

5 Enzootic Spinal Paralysis of the Horse. Paraplegia en- 

 zootica equorum. 



This is as a rule, an acute general infectious disease char- 

 acterized bv multiple capillary hemorrhages in the various or- 

 gans and especially in the spinal cord There is f requen ly a 

 gelatinous infiltration around the bladder and the genital or- 

 gans. It is caused by a specific streptococcus and its special 

 clinical feature is paralysis of the loins. 



Historical. The disease was first observed and accurately described 

 hv Com^nv in France in 1888. Further additions were made to the 

 hteratnre upon the subject by Mulatte (1897), Grange and Megmn 

 (1897 Bhn Lambert (1897), and Sorriau (1905). In Germany 



it appears to have been recognized as a specific disease by Schm dt 

 (188"^"^, and by Albrecht (1896). A contagions l^™^;f, P//^^'X'et ol 

 horse in India (Kumri) ^^^ ^escjibed by Burke (1897) The e^^^^^^^ 

 ogy of the disease was investigated by Schlegel (1906), f^^^^^ Z^^' 

 and recently bv Perucci (1910). The disease was connected uith para- 

 ??tic hemoglobinemia by Schlegel, as indeed it had already been by 

 earlier authors. 



Occurrence. The disease appears to have a very localized 

 distribution and occurs only in certain stables. In these sta- 

 bles, there may be an alternation of contagious cases with cases 

 that appear to be more sporadic in nature. 



Eepeated outbreaks have been observed in Germany by Schlegel, for instance 

 in PrTissia, Saxonv, Baden, Wvirtemburg, and Hesse. 



In France it" has been observed as an epizootic among army horses.
