240 Ninth Annual Report op the 



EQU1NIA MALLEUS (GLANDERS). 



The majority of cases were isolated. In one instance an 

 undertaker took his team and put it in a farmer's barn, with 

 an old gray horse, several miles from home. The gray horse 

 had been owned by this farmer for about a year. During 

 that time he loaned or hired it to his neighbors to work with 

 their horses. None of these animals showed any symptoms of 

 disease. About two weeks after the undertaker's horses had 

 been stabled with this gray horse, one was noticed to have a 

 nasal discharge. After using the ordinary remedies without 

 the desired results a veterinarian was called. Not having had 

 glanders in his vicinity, and not knowing that this horse had 

 been exposed, he treated it for distemper. A few days later his 

 attention was called to some ulcers on the inside of the hind 

 leg. This aroused his suspicion and upon a careful examination 

 he pronounced it glanders and so reported. As soon as the 

 veterinarian was satisfied the horse was suffering from gland- 

 ers, he immediately isolated the sick from the well. To do this 

 he had to put the remaining three horses in a barn with some 

 others. 



I applied the mallein test to the three exposed horses, also the 

 two others that were in the barn. The three exposed ones gave 

 a typical reaction, were condemned and post-mortem confirmed 

 the diagnosis. After the necessary measures were taken to 

 prevent further spread of the disease I immediately ascertained 

 the whereabouts of the gray horse. I found him upon a 

 farm about twenty miles from the home of the undertaker. 

 Upon making inquiry I was informed by the owner that while 

 this horse at times had a little discharge from his nostril, he 

 had worked with the various neighbors' horses for over a year 

 and no such a thing as symptoms of glanders had been seen. 

 Not only this, but he had been tied under the store and church 

 sheds without any apparent spread of the disease. I made an 

 examination of this horse and found some cicatrices upon the 

 Sihneiderian membrane. I informed the owner that the symp- 

 toms were very suspicious and I would have to make a mallein
