DIARRHOEA IN COLTS DUE TO THE “STRONGYLUS ARMATUS.”

By William Stothkkt, M.R.C.Y.S., Blackburn. 
On November 19th, 1892, I was called to the stud farm of 
R_ S-, Esq., I found there several colts the sub¬ 
jects of diarrhoea, one in particular, the chief cause of my ser¬ 
vices being requisitioned. This, big, a bony, two-year-old geld¬ 
ing, presented the following symptoms : Very poor condition, 
rough staring coat, profuse foetid diarrhoea, capricious appe¬ 
tite, insatiable thirst. The pulse, temperature, respirations 
and mucous membranes were almost normal. Learned that 
the loss of flesh and purging had been noticed two or three 
weeks, also that a yearling colt had died and been buried the 
day previous to my visit, having presented similar symptoms, 
with the addition of an abscess on the withers. 
I examined the food and pastures but failed to detect the 
irritant in operation, nevertheless I had the diet repeatedly 
changed, and the colts, which were fit to run out, moved to 
better drained pasture. 
The symptoms varied very slightly, the pulse never count¬ 
ing more than sixty to a minute, and the temperature never 
over 102.2 0 F., the animal always seeming bright and ever on 
the alert for liquids, the purging continuing most persistently. 
Once, about the third day of my attendance and after the 
administration of ol. terebinth, slight colicky pains were 
evinced, which disappeared after a couple of hours, and were 
not again manifested up to the time of the colt’s death on the 
15th inst. 
Medicines and food were tried without beneficial results, 
diarrhoea, emaciation and loss of appetite becoming percepti¬ 
bly worse daily, carried the patient off from sheer starvation. 
In the absence of any recognizable disease, I notified the 
owner my impression the cause of the persistent diarrhoea 
and its consequences was probably the presence in the walls 
of the intestines of parasites, and I thought if such were the 
case the strongylus armatus would be the species. 
Autopsy revealed besides the appearances of emaciation, 
a highly congested condition of almost the whole of the
