INFECTIOUS PARAPLEGIA IN SOLIPEDS IN EUROPE. 



Definition : Infections, non-febrile affection of solipeds with lesions of the 

 genito-urinary mucosa and nerve centres, paresis and paralysis. History. 

 Causes : Microbes varying ; bacteria of colon group ; infected urine, genital 

 mucus, brushes, combs, rubbers, mares especially exposed ; infection local or 

 general. Lesions : Congestion, exudation, swelling, discharge from vulva , 

 vagina, bladder, ureter, kidneys ; lumbar spinal cord, brain. Symptoms : 

 Mare, swollen open vulva, congestion and petechia;, bloody mucus ; horse, 

 swollen sheath, pendant penis, congested papilla, discharge ; paresis of hind 

 limbs, falls, inability to get up, incontinence of urine ; paresis of fore limbs, 

 of thoracic muscles, asphyxia, fever in late stages. Recovery. Diagnosis : 

 From hemoglobinuria by absence of dietetic cause, the infectious progress 

 and genital lesions. Prognosis : One-fourth to one-third die or fail to re- 

 cover. Treatment : Antiseptic washes and irrigations of vagina, urethra, 

 bladder, skin ; internally oil of turpentine ; slings. Prevention : Isolation, 

 disinfection, separate attendants, litter, sponges, etc., fly nets, screens, in- 

 sect powder, removal and disinfection of manure and garbage. 



Definition. A contagious, non-febrile affection of solipeds, 

 characterised by congestive and hsemorrhagic lesions of the gen- 

 ito-urinary mucosa, the spinal cord and its meninges, and by par- 

 aplegia or paresis of the hind limbs. 



History. This was described in 188S by Comeny, as occurring 

 in a regiment of French cavalry. Other outbreaks have been 

 observed in 1892 (Rancoule); in 1896 (Blin and Lambert). 

 Earlier outbreaks have doubtless been confounded with cerebro- 

 spinal meningitis, hemoglobinuria or simple paraplegia, the gen- 

 ito-urinary symptoms having been overlooked or viewed as 

 secondary. 



Causes. The disease, as hitherto observed, has been invariably 

 associated with microbian infection of the genito-urinary mucosa, 

 but no one microorganism has been found to be constantly pres- 

 ent. In the 1888 cases, Nocard isolated from the kidneys and 

 lumbar cord a small, motile bacillus which was not stained by 

 Gram's method and the inoculation of which proved fruitless.
