streptococci in foot-rot in sheep. 
Iii the so-called foot-rot of sheep which has occurred to a 
considerable extent in this State, we have, in the cases which 
have come to our notice, conditions similar to those found in the 
cattle which were suffering from suppurative cellulitis already 
described. It may be of interest to cite one or two specific 
cases with the results of the bacteriologic examinations. 
May 2, 1899, two sheep which were suffering from the so- 
called foot-rot were brought to Dr. Daw’s clinic. They came 
from a large flock in which forty or more animals were re¬ 
ported to be similarly affected. 
Sheep No. 1. An adult female in very poor condition. All four feet 
and legs were affected and the nails on one foot were quite loose. There 
was a purulent discharge from openings either between the claws or in 
the skin just above the hoof. The microscopic examination of the pus 
from this opening showed a number of bacteria but streptococci were 
especially numerous. They were not isolated in pure culture. The 
left knee was badly swollen and from the lower side of the swelling 
there was a discharge of a thin purulent substance which contained 
streptococci in large numbers. A few other bacteria, mostly micrococci, 
were associated with them. 
Sheep No. 2. An adult female, black, emaciated but in much better 
flesh than No. 1. The two fore feet and the left hind one were affected. 
The hind foot and the right fore one were discharging. The left fore 
foot was badly swollen above the hoof but the swelling did not extend 
high up- the leg. Fluctuation was marked. The skin was shaved, 
washed, disinfected and the abscess opened. A thick creamy pus was 
expressed. From this a number of tubes of media were inoculated and 
in each a streptococcus developed in pure culture. The pus from the 
discharging feet contained a streptococcus with other bacteria. The 
feet were treated locally with disinfectants by Dr. Law. In recovering 
' there was considerable thickening of the interdigital tissue. In this 
case the suppuration had not extended under the nails. 
The streptococcus isolated was fatal to rabbits. It differed, 
however, morphologically from the one obtained from cattle in 
that it grew in short chains in culture media and in the pus it 
appeared singly, in pairs, and in very short chains. 
In these cases, as with the cattle, we did not find the trouble 
to be a “ foot-rot,” but simply an inflammation of the subcutis 
leading to suppuration. This of course involved the skin and 
in cases where the pus burrowed beneath the nail the latter be¬ 
came loose. It is important that this form of infection should
