Meet with the bacteria, which account for 90 percent of living cells in the body. The human body is home to trillions of life forms, ranging from the core E. coli E.coli, which use their three tail to move vigorously to us inside, and ending with salmonella bacteria that cause food poisoning, but they can happily live on our skin, without exerting any influence on us.
Computer image of bacteria (blue and green) on human skin. Many species of bacteria found on human skin, especially those associated with the secretions of sweat glands and hair follicles. They usually do not cause problems, although some of them can cause acne. The bacteria can usually be a problem only if they penetrate the skin, such as through a wound or incision.
There are between 500 and 1,000 different species of bacteria in every human body. They proliferate, reaching the amount of 100 trillion cells – about ten times larger than human cells, which constitute an organism. Computer image of bacteria Helicobacter Pylori in the stomach, associated with the occurrence of gastric ulcers and cancer.
Teacher Cork Institute of Technology, Dr. Roy Slitor, said: “Only the human intestine contains almost four and a half pounds of bacteria, we, in fact, only ten percent of the people – the rest are different microbes.” Computer image of chains of bacteria pneumonia Streptococcus pneumoniae. This gram-positive bacteria oval, which is one of the reasons for pneumonia. Also, they can cause dangerous infections of the lungs.
The fact that we are composed mostly of different bacteria can cause alarm, but Dr. Slitordal understand that bacteria are good for us – and without them we would not have survived. “This is a bacterial-human interaction for the most part is symbiotic. In exchange for food and nutrition, the bacteria help us with digestion, the formation of vitamins and help to strengthen our immune system In addition, they protect us from opportunistic infections – the so-called “bad bacteria,” he said.
Computer image of E. coli in the intestine. They can cause bacterial diarrhea.
Conceptual image of several bacteria cocci on the cell surface.
Ciliary rod-shaped bacteria. Typical rod-shaped bacteria include E. coli and salmonella.
Obtained with an electron microscope image of Helicobacter Pylori.
Ciliated (with hair), rod-shaped bacteria.
Typical rod-shaped bacteria Escherichia coli and Salmonella bacteria, these bacteria have flagella (hair-like structures) on one end, which allow them to move.
Computer image of bacteria Enterococcus faecalis. The bacterium is one of the so-called superviruses, which are resistant to antibiotics.
Computer image of bacteria Helicobacter pylori in the human stomach. They cause gastritis and is the most common cause of stomach ulcers. Can also be a cause of cancer of the stomach and cause stomach bleeding.
