CLINICAL SYMPTOMS OF DOURINE.* 
By Dr. A. H. Quin, Creston, Ia. 
The object of this paper is to present the symptoms of 
dourine, as I found them in the field, and not to pose as an au¬ 
thority or bring forth anything that is new. My only aim and 
hope is to make the symptoms plain to you, that you may recog¬ 
nize a case, should you meet it in your practice. 
I believe the symptoms may be presented to you in few words. 
It is generally considered that dourine is an infectious disease 
and, under natural conditions, is transmitted only by breeding, 
and is due to the Trypanasoma Equipurdum. Let us divide and 
describe the symptoms as: acute, subacute, and chronic. Of 
these, I believe the only cases you may hope to detect without a 
history are the acute and the chronic. 
My first experience with this disease was in the spring of the 
present year, when I received a notice from Dr. Gibson to go to 
Taylor county and examine a stallion, reported by the township 
trustees as suffering from some venereal disease, which I diag¬ 
nosed as dourine and which diagnosis was approved by Dr. Bau¬ 
man in consultation and further approved by federal officers. 
In this case the penis protruded and hung pendulent. It was 
swollen for probably four inches and a number of vesicles were 
presented near the glands. He had a number of well-marked 
placques on the right side of his body that you could not help but 
detect. Here let me say the placque is the symptom. When you 
see a placque, rest assured you have a case of dourine, and I be¬ 
lieve you are not sure of a case unless they are present, unless 
you have a history of infection. 
I may add a little advice to the younger practitioners. When 
you are called to see a stallion suffering from venereal disease, 
always get as much history as possible.
