There are many different types of bacteria. The bacterium can be defined as unicellular organisms. This means that it consists of a single cell. Bacteria can be found in various shapes and sizes. They live literally everywhere. If we tried to list all kinds of bacteria, it would take a lot of time and space! So we just mention a few types that are most common. Bacteria can be classified according to size, shape, metabolic activity, the conditions necessary for their growth, and DNA sequencing. Reed (also called bacilli), spiral (called spirilla) and sphere (also known as cooks). Of course, some bacteria are more complex when it comes to forming. However, these basic forms. Bacteria can be anaerobic and aerobic. This classification is based on the oxygen necessary for the reproduction of harmful bacteria. If they need oxygen, they are aerobic. If the bacteria do not require oxygen to survive, they are called anaerobic. These bacteria can not stand oxygen and die when exposed to it. They live in the oceans, and under the ground. Bacteria may be gram-positive and Gram-negative. This classification is based on the Gram staining method. Bacteria can be autotrophic and heterotrophic. This classification is based on growth and reproduction of bacteria. Heterotrophic bacteria use the sugar from the environment, while autotrophic bacteria have their own way to get sugar, regardless of their environment. Another classification based on morphology, biochemical factors, and DNA sequencing. According to this classification, the bacteria can be:
Xenobacteria, bacteroids, Aquificae, Firmicutes, Cyanobacteria, Thermomicrobia, proteobakteriya, planktomitsetov, Fusobacteria, Chrysogenetic, Verrucomicrobia, Chlorobia, Fibrobacter, Flavobacteria and spirochetes. You can also find other classification as bacteria sweet water, extreme temperature resistant bacteria (they can live in extreme conditions such as very hot or very cold environment), ocean water bacteria, bacteria that live in very acidic, aerobic and anaerobic bacteria, heterotrophic and autotrophic bacteria, the bacteria that live in an alkaline medium, etc. Some bacteria can live in very high radiation. These bacteria are very stable and fun to learn. Some bacteria are usually found in living things. Even the human strattera no prescritpion body has a normal, natural bacteria that are useful and much needed for the body to function properly. However, there are bacteria that cause some diseases, such as streptococcal bacteria, for example. These well-known bacteria cause inflammation of the throat infection. You might have heard about them. Some bacteria are very dangerous. For example, there meningococcal bacteria that cause meningitis. This type of meningitis known as bacterial meningitis and it can be very dangerous. This disease can cause serious and irreversible damage, and sometimes even coma and death. .
