In order to bring the attention of stock owners to the importance 

 of vaccination against blackleg, notices are placed in the newspapers 

 in sections of the State from which the disease has been reported in 

 previous years. 



Local veterinarians can make the diagnosis and apply the vaccine, 

 which is furnished, free of charge, by the Board.

GLANDERS 



Suspected cases of glanders were reported from eighteen counties 

 during the year. A positive diagnosis was made in fourteen coun- 

 ties. One man in the State contracted the disease and died. Each 

 positive case of the disease in horses has been disposed of in ac- 

 cordance with the rules and regulations of the Board. Veterinarians 

 seldom make a mistake in diagnosing advanced cases of glanders, 

 yet in nearly every instance it has been confirmed by the laboratory 

 examination and all horses known to have been exposed to this in- 

 fection were tested with mallein. In many cases the compliment 

 fixation test, agglutination test and Strauss method, one or all have 

 been applied to suspicious cases. Well marked physical cases and 

 animals that react to the Strauss method are destroyed. Those that 

 have been exposed and react to the other tests, but show no physical 

 symptoms may be appraised and destroyed or kept under provisional 

 quarantine and retested. This plan has been followed for years in 

 Pennsylvania, and so far no trouble has arisen from reacting horses 

 that show no physical symptoms of glanders.
