What are some types of bacteria?

bacteria are the largest group of unicellular organisms on Earth and form most of the known biomass in the world. There is an incredible number of bacteria types on the planet, most of which have not yet been classified. Many of what was once considered bacteria is now considered part of a separate domain, Archaea. Different phyles are generally classified into two different groups because they have an external membrane or lack the external membrane, with a series of phyles, not yet unspecified. Some bacteria are incredibly small as Bakets in the family Mycoplasma , which are as small as the largest viruses, on approximately 0.3 micrometers. Others are relatively chr.eter (0.019 inches) in length.

There are two main types of bacteria in terms of shape: bacilli and coca. Kokci are spherical bacteria, while bacilli are shaped like rods. The third smaller group consists of bacteria that are formed in the spiral formationArech known as Spirilla. In addition to these main groups, there are some foreign variations, such as those that look like commas, leaves of plants or even long pulled ladders. Different types of bacteria tend to group in different ways, with the same shape of the basic shape determining what larger groupings are part.

For example, bacilli can be singular or connected in chains. The bacillus is the only, slightly rounded rod -shaped bacteria. coccobacillus , on the other hand, is also the only node, but it is a much more oval shape. diplobacteria looks like two bacillus Connected end. Streptobacteria is a long chain bacill, end to the end. There are countless types that have small changes in this basic creation of bacillus.

Cocci, similarly, have different configurations. The coccus itself looks like the only circle, while diplococci looks like two cocus stuck together. Streptococcus, bacteria responsible for the string throat, they look like a long chain of dick together, while staphylococcus , bacteria responsible for Staf infection look like a cluster of grapes.

There are only a few harmful to people among many types of bacteria. Most are relatively harmless, while some are really useful. For example, many live in the digestive tract and help spend food. Other bacteria live on the skin and fight from various harmful mushrooms. Others still live around mucus membranes and prevent other harmful membranes in the stay. In fact, the average human body contains about ten Times more bacterial cells than real human cells, most of which make good work for the body.

However, some types of bacteria are harmful to people. The most famous of these are probably Staphylococcus and Streptococcus . Others include Campylobacter , which is the main cause of food poisoning among people. Another known historical bacterium is yersinia dogTis , bacteria found in fleas that transmit the bubonic plague to human beings.
