76 SEPTIACEMIA HEMORRHAGICA 



§ 6i. Differential diagnosis. Septicaemia hemorrha- 

 gica in cattle must be differentiated from anthrax, sympto- 

 matic anthrax, and the affection known as "corn stalk dis- 

 ease." Death from this disease must also be distinguished 

 from those due to certain accidental causes, poisoning, or the 

 -effect of over eating of grain or green fodder (hoven). The 

 suddenness with which the animals may die from all of these 

 causes renders the symptoms, should they be observed, of very 

 little value in making a diagnosis. It is necessary, therefore, 

 that in all cases, especially with the first animals to die that 

 -careful post-mortem and bacteriological examinations should 

 be made. 



In case of septicaemia hemorrhagica, the cultures will 

 usually reveal the presence of Bad. bovisepticum. The lesions 

 hemorrhagic in nature. 



Incase of the "cornstalk disease" the lesions may consist 

 of small hemorrhages (petechise) especially of the serous 

 membranes and heart. The cultures will be negative. 



With anthrax and symptomatic anthrax, the specific bac- 

 teria of these diseases will be found. 



§ 62. Prevention. When this disease occurs it is im- 

 portant to remove the unaffected animals to other fields or en- 

 closures. It is well to divide them into small groups if pos- 

 sible. The carcasses of animals that die should be burned or 

 buried deeply with a good covering of a disinfectant such, for 

 example, as quick lime. Should death occur in a stable, all 

 contaminated litter should be burned and the floors, mangers 

 and walls thoroughly disinfected. 



Experiments have been made directed towards protective 

 inoculation, but thus far the results have not been sufficiently 

 -satisfactory to warrant the recommendation of the methods.
