Welcome to Bacteria Microscopes
Bacteria are found everywhere including our surrounding environment and inside our bodies. Bacterium is a primeval form of life and can be unicellular or a single celled micro-organism. Bacteria can only been seen through a microscope as they are so tiny that they exceed no more than a few micrometers in length. The shape of bacteria differs and can be found in the form of a rod, sphere or spiral. As bacteria do not have a nucleus, they possess a single circular DNA chromosome that is located within the cytoplasm of the cell. There is no sexual interaction and bacteria multiply by binary fission.

Depending on circumstances, bacteria may or may not cause disease. As long as a bacterium does not over populate or colonize a specific area in the body, it is unlikely you will suffer a disease. Studies have proven that there are more bacterial cells than human cells in the body, with most of them situated in the skin and digestive tract. To understand the work and components of bacteria, it is now studied in laborites for bacteriologists and medical researchers to study and observe to determine how to work for and against bacterial diseases. Bacteriology is a branch of a superior study of microorganisms and microbiology.
The best way to see bacteria in full effect is to know how to use the features of a microscope. The higher the quality and versatility, the more expensive the microscope it will be. The basic instructions to be able to view bacteria with appropriate magnification is to learn how to obtain good resolution and sufficient contrast, find the focal point and recognize the bacteria when you see it.
