What is bacteria? Where do bacteria come from and how do we interact with us? All very valid questions. When the earth was formed 4.6 billion years ago, the environment was too hostile for any life. However, as the earth cools, no one knows the answer that life was formed from the primitive soup flowing on the surface of the earth, but it is theoretical and theoretical. How did it happen? Again, we can summarize that chemical explosions occurred and only the important elements of life formation were gathered.
Scientists in the 1950s conducted an experiment simulating conditions that the earth is considered to be cold by combining hot water, air and electricity. This experiment ended with the production of 5 amino acids of protein and building blocks. A similar experiment was also conducted in 2008, but this time more elements were introduced. These conditions were thought to imitate volcanic eruptions. Experiments targeted the synthesis of 22 amino acids.
During pre / life, did amino acids form proteins and proteins joined to form life?
Microorganisms are thought to survive nearly 3.8 billion years, like plants developed 1.9 billion years ago from the ameba and cyanobacterium fusion. Multicellular organisms are thought to have developed 630 million years ago. The organization moved from sea to land 3.2 billion years ago.
Some scientists believe that they exist on Mars decades ago, come to Earth with meteorites and fuse with onshore proteins to form life. Are we really from Mars? We never know.
Clearly, there are many other beliefs about our existence like creationism, but this article does not focus on the background of bacteria and the impact on human life, but a different article The topic.
Several scientists believe that all life develops from bacteria and that fusion and mutation play an important role in the evolution process. They have reached this conclusion because of the remarkable similarity between cells and cellular processes in bacteria, plants and animals. The tree of life divides all living organizations into three groups:
Bacteria
Old-fashioned
Eukarya
There are more microbes in the universe than the stars, so it is suggested. Bacteria are ubiquitous and they are found in humans, soil, water and the atmosphere. Dust clouds include many species of bacteria and virus particles that cause diseases such as meningitis, coral disease, pneumonia, septic shock, heart inflammation, asthma, influenza, valley fever and feet and mouth included.
If you are ready to take a shower, let's steer it and drive it for 1 minute before being exposed to the dangers of getting your face filled with bacteria. Scientists, Mycobacterium avium These bacteria on the shower faucet cause respiratory diseases like TB. Two other strains of these bacteria actually cause tuberculosis and leprosy.
All microorganisms causing disease are called pathogens. However, there are microstructures that are more beneficial than pathogens. If there really is no specific species we will die. Humans are bitten by bacteria that have suppressed inflammation that may be caused by injuries and pathogens. Staphylococcus aureus It is a symbiotic bacterium that is part of the natural microflora of humans (and other animals). Microorganisms that are not part of our natural plant are called transients.
Staphylococcus aureus It releases molecules that prevent skin cells from releasing chemicals that cause inflammatory responses. Inflammatory response is important to help recover from injury, but prolonged infection can cause skin diseases such as psoriasis.
We possess numerous symbiotic bacteria in our body, and in our body, with other species. For example, over 180 kinds of bacteria and fungi inhabit our skin. The vast majority of the skin microflora is centered on sweat glands such as armpits, reproductive organs, nipples, and navels. Half of these bacteria belong mainly to genus Streptococcus, Corynebacterium, Staphylococcus and Propionibacterium That species causes acne.
There are 17 known genes known to belong to the bacterial phylogenetic tree. Each genus (genus = plural) can have many different species. Salmonella It is a genus. There are over 2,500 known species Salmonella .
The amount of bacteria present on the skin depends on several factors, including the weather, the age of the host (many bacteria in infants, especially pathogens more than adults) and personal hygiene.
There is no microbial flora in the mouth due to the antimicrobial properties of lysozyme which is a constituent of saliva. However, poor dental hygiene that allows the formation of plaques can cause temporary bacteria to grow and grow. Plaque is a very good growth medium for several different genus bacteria and causes disorders such as dental caries, gingivitis and periodontal disease.
The gastrointestinal tract (GI) is a single elongated tube extending from the mouth to the anus. It begins at the food hall. There is a microflora in the esophagus. There are up to 30 types of bacteria between the esophagus and the anus. Several studies have shown 10 bacterial cell numbers at power of 14 in the GI tract. Considering that six times the power of 10 is 1 million it is a lot of bacteria!
Bacteria will be responsible for:
Steroid metabolism (which modifies the steroid released from the gall bladder after synthesis in the liver) The modified stereotype is then absorbed by the intestine
Synthesis of vitamins such as B1, B2, B6, B12 and K
Decomposition of fiber (digestible element)
Production of gas such as methane, hydrogen, carbon dioxide.
Without bacteria, we can not digest food.
There are many microbial flora in upper airway (sinus - larynx) of healthy person. The lower respiratory tract (trachea - lung) should include only a few if any.
Both male and female urogenital tracts contain a small number of resident bacteria. Urine is maintained in a sterile environment in the bladder. Bacteria inhabit the urethra. One such species, Lactobacillus acidophilus Is present in the vagina, ferment glycogen and release lactic acid. The acidic environment outweighs diseases caused by pathogens that do not favor acidic environments from developing.
