A BACTERIOLOGICAL STUDY OF FISTULOUS WITH¬ 
ERS, BOTRYOMYCOSIS AND INFECTED 
WOUNDS IN THE HORSE. 
By Carl W. Gay, D.V.M., Syracuse, N. Y. 
It is customary at the New York State Veterinary College 
to make, as far as possible, bacteriological examinations of the 
cases presented at the college clinic. The results of certain of 
these investigations have already been published.* The 
awarding of a University Fellowship to the Department of Vet¬ 
erinary Science has made it possible to conduct, during the 
past year, more specific investigations concerning the etiology 
of wound infection. 
The cases herein described, from which our data was 
obtained, include all of those which, for convenience, may be 
discussed in the following groups, viz.: fistulous withers, poll 
evil, scirrhous cord, deep shoulder abscesses, infected open 
wounds and infected operative wounds. Examinations were 
also made of the skin after thoroughly disinfecting it for opera¬ 
tion. 
In this work the usual culture methods were employed, viz. : 
tubes of bouillon and slant tubes of agar were inoculated, and 
sub-cultures made from the colonies which developed on the 
surface. In some cases, agar plate cultures were used, but in 
most instances there was no difficulty in securing well isolated 
colonies on the agar slant. In using agar plates, some difficulty
