102 BACTERIOLOGY FOR NURSES 



Entrance to the body of the horse is probably 

 through an abrasion of the nasal membranes, or by 

 way of the alimentary tract, and more rarely through 

 the broken skin, while in man nearly all cases are 

 the result of entrance through abrasions. 



An attack of glanders does not confer immunity 

 upon either man or beast. 



The mallein test as a means of diagnosis is used in 

 the same way that tuberculin is employed for the 

 diagnosis of tuberculosis in cows. Mallein is the 

 filtered products of the growth of B. mallei. 



ACTINOMYCOSIS 



A disease known as "lumpy jaw/' which is 

 common to cattle and occasionally seen in man, 

 is due to a fungus-like organism known as acti- 

 nomyces. 



When growing in colonies the fungus presents a 

 raylike appearance resembling a rosette which is 

 discernible to the naked eye. The outer ends of the 

 films forming the rosette are sometimes blunt or 

 " clubbed." 



The staining and cultivation of actinomyces is 

 attended with considerable difficulty. 



Much discussion has been spent upon the ques- 

 tion as to whether there are two distinct species of
