BACTERIOLOGY IN A NUTSHELL.

Multiplication. 
distinguished bacteriologists of the present 
day and who is carrying on his work at 
Pasteur Institute, Paris, France, as successor to 
Pasteur. While scientists differ as. to the method 
of warfare as carried on between the cells of the 
body, termed phagocytes, and the germs of dis¬ 
ease, all agree that the healthy body has the 
power to overcome and exterminate such foes by 
their means. 
The body which is not healthy, and in which 
normal resistive power is absent, on the other 
hand is not able successfully to fight disease- 
producing germs which invade it at one point or 
another, they overcome weakened resistive forces, 
increase and multiply within the body, and we 
become victims of the disease the special form of 
bacteria present produces. 
There are two methods of multiplication in 
the bacterial world—fission and spore formation. 
The method by which micro-cocci and spirilla 
multiply is termed fission; fission in common 
everyday language means simply division. They 
rapidly separate or divide into a number of sec¬ 
tions, each of which soon leaves the parent cell, 
and in turn divides into other sections or parts. 
This process of division and subdivision is kept 
up as long as the germs have proper soil to exist 
upon, and provided, also, the temperature, air and 
moisture are such as they require. 
Bacilli multiply in much the same way and 
under conditions similar to those required by the 
micro-cocci and spirilla. This is especially true 
of the bacilli which are non-spore-forming.
