Слово «бактерии» у большинства людей associated with something unpleasant and with a threat to health. At best, dairy products come to mind. At worst - dysbiosis, plague, dysentery and other troubles. But bacteria are everywhere, they are bad and good. What can hide microorganisms?
Bacteria in Greek means "wand". This name does not mean that harmful bacteria are meant.
There is a constant struggle in our body,which are harmful and beneficial bacteria. Through this process, a person receives protection from various infections. Various microorganisms surround us at every step. They live on clothes, fly in the air, they are omnipresent.
Наличие бактерий во рту, а это порядка сорока thousands of microorganisms, protects the gums from bleeding, from periodontal disease, and even from angina. If a woman has a broken microflora, she can start gynecological diseases. Observance of elementary rules of personal hygiene will help to avoid such failures.
The state of the microflora completely dependshuman immunity. Only in the gastrointestinal tract is almost 60% of all bacteria. The rest are located in the respiratory system and in the genital. About two kilograms of bacteria live in a person.
A newly born baby has a sterile bowel.
Beneficial bacteria are: lactic acid, bifidobacteria, E. coli, streptomyces, mycorrhiza, cyanobacteria.
Все они играют важную роль в жизни человека.Some of them prevent the occurrence of infections, others are used in the manufacture of medicines, and others maintain a balance in the ecosystem of our planet.
Harmful bacteria can cause a number of humanserious diseases. For example, diphtheria, anthrax, sore throat, plague and many others. They are easily transmitted from an infected person through the air, food, touch. It is harmful bacteria, whose names will be given below, spoil the food. From them there is an unpleasant smell, rotting and decomposition, they cause disease.
Bacteria can be gram-positive, gram-negative, rod-shaped.
| Titles | Habitat | Harm |
| Mycobacteria | food, water | tuberculosis, leprosy, ulcer |
| Tetanus rod | soil, skin, digestive tract | tetanus, muscle spasms, respiratory failure |
Plague wand (considered by experts as a biological weapon) | only in humans, rodents and mammals | bubonic plague, pneumonia, skin infections |
| Helicobacter pylori | human gastric mucosa | gastritis, peptic ulcer, produces cytoxins, ammonia |
| Anthrax bacillus | the soil | anthrax |
| Botulism stick | food, contaminated utensils | poisoning |
Harmful bacteria are able to stay in the body for a long time and absorb nutrients from it. At the same time, they can cause an infectious disease.
One of the most resistant bacteria ismethicillin. He is known more under the name "Staphylococcus aureus" (Staphylococcus aureus). This microorganism can cause not one, but several infectious diseases. Some types of these bacteria are resistant to powerful antibiotics and antiseptics. Strains of this bacterium can live in the upper respiratory tract, in open wounds and urinary canals of every third inhabitant of the Earth. For a person with strong immunity, this is not dangerous.
Harmful bacteria for humans - this is alsopathogens called salmonella typhi. They are the causative agents of acute intestinal infections and typhoid fever. Such types of bacteria, harmful to humans, are dangerous because they produce toxic substances that are extremely dangerous for life. During the course of the disease intoxication of the body occurs, a very strong fever, rash on the body, increases the liver and spleen. The bacterium is very resistant to various external influences. It lives well in water, on vegetables, fruits and reproduces well in milk products.
К самым опасным бактериям относится также bacterium Clostridium tetan. It produces a poison called tetanus exotoxin. People who become infected with this pathogen experience terrible pains, convulsions and die very hard. The disease is called tetanus. Despite the fact that the vaccine was created back in 1890, 60 thousand people die from it every year on Earth.
And one more bacterium that can lead tohuman death is mycobacterium tuberculosis. It causes tuberculosis, which is resistant to drugs. If you ask for help late, a person may die.
Harmful bacteria, the names of microorganismsDoctors from all directions study from a student's bench. Every year, health care is looking for new methods to prevent the spread of infections dangerous to human life. With the observance of preventive measures do not have to spend energy on finding new ways to combat these diseases.
To do this, it is necessary to identify the source in time.the occurrence of infection, determine the number of cases and possible victims. It is imperative to isolate those who are infected and disinfect the source of infection.
The second stage is the destruction of pathways through which harmful bacteria can be transmitted. To do this, conduct appropriate propaganda among the population.
Under the control take food objects, ponds, warehouses with food storage.
Everyone can resist the harmfulbacteria, strongly strengthening their immunity. Healthy lifestyle, adherence to elementary rules of hygiene, protection of oneself during sexual intercourse, use of sterile disposable medical instruments and equipment, complete restriction from communicating with people in quarantine. If it enters the epidemiological area or the source of infection, it is necessary to strictly comply with all requirements of the sanitary and epidemiological services. A number of infections are equated in their effects to bacteriological weapons.
