BULLETIN 65, U. S. DEPARTMENT OF AGRICULTURE. 



Dr. Mumi, of Kearney, Kebr., had apparently good success from 

 the use of diphtheria antitoxin as a prophylactic agent, since not a 

 single animal developed the disease out of over 500 injected. It 

 may be with this treatment, as with others, that good results 

 were due to the fact that the disease was on the wane before treat- 

 ment was commenced, but no other line of treatment gave as good 

 apparent results. Dr. Kaupp also reports in the Breeders' Gazette 

 that only 1 horse died out of 900 inoculated with a diplo-strepto- 

 coccic bacterin he prepared, but the injections were made so late in 

 the outbreak that its value is still problematical, since thousands of 

 horses m the affected area at this period failed to develop the disease, 

 although they had received no preventive treatment whatsoever.
