BACTERIOLOGY IN A NUTSHELL. 



Methods of 

 Entrance. 



Predisposing 

 Causes. 



Various parts of the system are affected as 

 shown by elevation of temperature, nausea, and 

 frequently vomiting, headache, rapid pulse, and 

 after the disease is well advanced in bad cases 

 there may be delirium and exhaustion. The 

 disease sometimes proves fatal. Cleanse, dis- 

 infect and fumigate rigidly. 



Tuberculosis. All forms of this disease, 

 which attacks various parts of the human struc- 

 ture, are caused by the bacillus tuberculosis. 

 Tuberculosis of the lungs is called phthisis or 

 consumption. When the germs attack the 

 lymphatic glands the disease is spoken of as 

 scrofula. Tuberculosis of the skin is termed 

 lupus. The nurse meets with tubercular joint 

 disease, tubercular disease of the kidneys, 

 tubercular meningitis, tubercular peritonitis 

 and so forth. 



The germ which is responsible for the de- 

 velopment of tuberculosis generally gains ad- 

 mission to the system through breathing in air 

 in which they are circulating, but it may be 

 taken in through other sources ; for instance, by 

 drinking milk containing the germs. Jersey 

 cows are said to be subject to tuberculosis and 

 their milk apt to contain the germs. Wounds 

 also admit the germs. 



Persons predisposed to tuberculosis are those 

 whose chests are not well developed, whose cir- 

 culation is poor and whose vitality is low, par-
