Bacteria parasites Bacteria in the human body, and their interaction

Bacteria are the oldest organisms living on and around us everywhere. As a rule, most of them single-celled organisms. A bacterium is a cell that lacks a nucleus. Instead, it is a nuclear substance in an atomized state. The shape of the bacteria can have any. Cage is dressed in a thick shell which serves as protection and support. Inside it the cytoplasm. That's all it is, what it consists of simple bacteria. Some other species have special flagella for movement, a special internal structure. They are found around the globe, even there are certain types of bacteria that lived millions of years in permafrost. Living conditions for them are varied. They can live in air, in water, in living organisms, and especially a lot of them in the soil. Of the General school biology course it is known that they are divided into useful bacteria and parasites, autotrophs and heterotrophs. Autotrophs feed themselves, they form nutrients for your existence, and heterotrophs can only eat ready organic matter that either someone already did or parasitizing another organism.

The types of bacteria and their livelihoods

To heterotrophic microbes include bacteria – saprophytes (they are getting useful substances, which are taken from dead organic material), symbiosis (living together with other organisms and give them any good), bacteria – parasites (live at the expense of another organism).

The role of bacteria, which are included in the class is useful, especially for a person that is known for its beneficial effect on the body. Examples of such bacteria as Lactobacillus. They fight various types of viruses, infections, improve the General condition of the body and improve a person's mood. Such microorganisms we are trying to increase in our body, raising their consumption of dairy products. While the parasitic species of bacteria leads to terror, in a panic. Unfortunately, such types of variety. Besides the fact that they lead a parasitic way of his life, fed by his donor, so also can cause various diseases. However, one should consider the fact that some parasites and viruses have a positive effect on our body and help to prevent already existing problems in the human body. Here it is possible as an example to say about the use of leeches in medicine, virotherapy, writing viruses for the treatment of infections, vaccination.

The human body for members of the group is a beneficial environment for breeding and good living. Such bacteria penetrate into someone's body through cracks, pores and exist at the expense of another organism. They are hardy and adapt to any environment, even to anoxic.

It is possible to prevent parasites in the human body

Since childhood, man is taught after the streets, visiting the toilet and other establishments, as soon as possible wash hands with detergent. And this is not casual. All known Shigella dysenteriae can also be the cause of such infections as dysentery that causes bloody diarrhea.

Strangely enough, the name of the well-known and terrible disease, how the disease tuberculosis, the causative agent of which is the tubercle Bacillus, and the hypothermia is secondary symptoms.

Salmonellosis and typhoid fever is no less scary for the person

To prevent the above mentioned diseases, people spend vaccination – a slight modification of the germ – parasite in the body, causing a particular illness to strengthen the immune system against potential disease in the human body. You need to handle foods, especially those bought in the stalls, pasteurized dairy products, frequently wash hands, General body hygiene and timely cleaning of housing facilities. After all, in the dust that sits in the house of the cabinets, upholstered furniture, carpets, contains parasites that cause salmonellosis. But still it is worth considering that parasites carry other organisms, such as tick encephalitis, pigeon – tuberculosis of the face, toxoplasmosis, and the cow – the bovine tapeworm.

Infectious period of a disease lasts in different ways, so it is not possible to find the root cause, which was the illness, so it is best to adhere to disease prevention.

Though the role of bacteria and bacteria parasites in nature is diverse, but it is necessary for the existence of all niches of life.
