Bacteriology is all about the science of bacteria, which are a group of single celled micro-organisms only certain of which cause disease in humans. They are abundant in the soil, air and water most being harmless to humans, some being beneficial such as those that live in our intestine and help break down our food or digestion. Bacteria that cause disease are called pathogens these including pathogens that cause such terrible illnesses as anthrax, plague, pneumonia, syphilis, tetanus and tuberculosis. In developed countries, antibiotics are used to treat bacterial infection in humans and the bacteriology studies are primarily directed towards researching of this.

The types of pathogenic bacteria that cause illness do so by colonizing our human bodies and that is what makes us ill. This type thrive in warm, moist conditions and reproduce by dividing into two cells inside your body which in turn divide and so on and under ideal conditions the division can happen about every 20 minutes so after only 6 hours one single bacteria that has got into you (say) when somebody sitting next to you on the bus on your way to work accidentally sneezed and you unwittingly breathed in a droplet of their expelled air. The consequence is in worse possible scenario it can have multiplied 6 hours later to form a colony of more than 25,000 of that one bacterium. In most cases our body's immune system attempts to destroy the invading bacteria sometimes failing to do so and so you get ill. Bacteriology is the science studying this and finding ways of treating, easing or preventing the range of diseases in humans caused by these pathogens colonizing our bodies.

In Bacteriology finding out which bacteria is causing your disease is first necessary and to do that it must be isolated. A throat swab or a specimen of urine, feces, blood, spinal fluid, pus or, sputum is first taken from you (the infected person) and this is examined under by one of 3 methods :-

1. STAINING - The application of special stains makes it possible to view and differentiate between bacteria under a microscope. For example in a sample treated with Grain's stain staphylococci or streptococci bacteria will turn purple while other types like salmonella turn red.
or
2. CULTURE with this method the sample is introduced on to a nutrient plate like agar or blood agar and incubated at body temperature where the bacteria multiply and can then be identified by their growth and appearance needs. Different antibiotics will be introduced into the colonies of bacteria and the effects studied to find our which will be effective in treating the infection. Any clear areas around each disk reveal to the bacteriologist that the bacteria are being killed by a particular antibiotic.
or
3. ANTIBODY TESTING which is effected by extracting serum from an infected human's blood and adding this to a sample of the type of bacteria suspected to have caused the infection. If that suspicion is right , antibodies against the bacteria also present in the serum will be seen to clump together with the bacteria in the sample.

Thanks to bacteriology studies, immunity to certain killer bacterial diseases such as diphtheria, typhoid, pertussis and tetanus can be achieved by injecting you with weakened forms of the bacteria or their poisons, this being termed "active immunization".
