BACTERIOLOGY IN A NUTSHELL. 



Immunizing 

 Power of 

 Vaccination. 



Antibacterial serums are not antitoxic. In 

 this connection the question riaturally arises: 

 Why are there no antitoxic serums for some of 

 these infections? The answer of investigators 

 is : "Because of : 



I. The difficulty in liberating the toxins 

 from the bacteria. 



II. The difficulty of forming proper rela- 

 tions between the amboceptor and complement. 



III. The inaccessability of the antitoxin to 

 the germ, as in cholera." 



III. VACCINATION. 



Vaccination against smallpox is a preventive 

 treatment discovered by Dr. Edward Jenner of 

 England. He demonstrated successfully its 

 immunizing power in the year 1796, several 

 years after his discovery. Jenner was born in 

 Berkeley, Gloucestershire, England, in 1749. 

 He died in 1823. 



We have all grown familiar with the term 

 vaccination as applied to the prophylactic treat- 

 ment of smallpox. By the vaccination process 

 the immunity gained extends over a protracted 

 period. It is taught by some authorities that in 

 consequence of vaccination the cells of the body 

 have been 



Trained "trained to produce the corresponding receptors- and that 



Body Cells. when subsequently micro-organisms gain an entrance to 



the body antibodies form rapidly and overcome the 



invaders in their incipiency."
