The 5 most dangerous bacteria

Some of these bacteria can live in your house

We are surrounded by bacteria. Among them are the ones that help us to live (e.g., digest food), but also those that can erase part of the population from the face of the Earth. Although modern medicine has learned to fight certain pathogens, the most tenacious part of the bacteria currently remains undefeated. Among them there are five of these "thugs" that can cause serious illness and even death. Worst of all — to pick up such bacteria can be almost anywhere.

the Most dangerous bacteria

According to some scientists, by 2050 the mortality of mankind from bacteria may exceed the death rate from cancer. From these dire predictions? A vivid example is the plague Bacillus Yersinia pestis, a bacterium that . With the plague managed to cope, but there are no guarantees that this history will not repeat itself.

So far, microbiologists have identified a number of the most dangerous bacteria that are already common. And not beat mankind due to the high level of medicine and awareness of the people themselves (which, for example, do not drink dirty water, which can contain dangerous bacteria).


a Bacterium that does not allow you to breathe — Clostridium botulinum

One of the most fierce and terrible bacteria. It causes botulism — a serious disease characterized by severe damage of the human nervous system. Subsequently, the bacterium leads to paralysis of the respiratory muscles, a man just can't breathe. As a result, he may die from lack of oxygen in the body.

Clostridium botulinum normally dwells in the soil, often found in the intestines of horses and other animals, less frequently found in the human gut. There she goes, usually from home-canned — mushroom, beans and beets. Bacteria can also contain sausage, meat products, smoked and salted fish. To avoid becoming a victim, doctors recommend not to eat canned food, if they have swelled or broken packaging integrity, and conduct heat treatment of food. In the case of meat products — to choose a trusted stores and manufacturers.

E. coli — Escherichia coli

This bacterium has a beautiful name Escherichia coli, but do not be misled by her name. the E. coli is dangerous because it has as harmless strains are able to survive inside humans and animals, and pathogenic, causing intestinal infections.

Dangerous types of E. coli usually enter the body with dirty water, rare meat (if only it is not intended for raw consumption), unwashed fruits or vegetables. Therefore it is necessary to take responsibility for the food that you consume. If E. coli is ingested, it is urgent to see a doctor — he will prescribe treatment in the form of antibiotics.

anthrax — Bacillus antracis

Yes, this dangerous disease is also caused by a bacteria — its occurrence contributes to Bacillus antracis. This deadly bacterium can decades to remain on the surface, getting into the human body through the gastrointestinal tract or airborne droplets. It can be transmitted from animals to people, so if the farm is found flash anthrax, all the cattle, as a rule, destroyed.

Most of the time a bacterium spends in the form of a dispute, the inactive form with extraordinary powers of survival. She , from the bathroom with a powerful disinfectant to heating at 180 degrees for two minutes.

Bacteria Bacillus antracis — anthrax

Just to catch anthrax now it is impossible — usually, the infection occurs through contact with the dead during epidemics of this disease animals. Or if the army decides to use the bacteria Bacillus antracis as biological weapons. In the USSR, for example, in large quantities. In 1988, nine years after the leak of anthrax (the so-called anthrax) at the place of production, which led to the deaths of at least 105 people, the Soviet Union finally decided to get rid of inventory. Huge vats of anthrax was involved with bleach, and taken to the port city of Aralsk on the shores of the Aral sea. There they were loaded on barges and towed to the island of the Renaissance. The area was cleaned only after many years.


is the causative agent of cholera — Vibrio cholerae

No one want to meet this dangerous bacteria, because cholera — a very serious disease in which there ischronic diarrhea, dehydration, vomiting and seizures. In the end, due to the loss of water in the body and lack of treatment the person may die.

Basically, the bacterium lives in dirty water, but in the Russian latitudes, you hardly will meet. The primary location of infection is considered the island of Haiti, where in 2010 there was one of the deadliest epidemics of the planet. Then infection , of whom 3,000 were killed. With timely treatment, the mortality from cholera is quite low, but without antibiotics you risk to die a infected.

But this does not mean that you need to drink the dirty water from the tap!


a Bacterium that causes tetanus — Clostridium tetani

The Pathogen tetanus tetanus Bacillus, enters through the damaged skin (wounds, burns, and so on). It lives in the soil, so you should be particularly careful in the cuts, for example, in the garden or yard. Some bacteria tetanus can survive for several months or even years!

When infected with tetanus, the first symptoms can appear anywhere from three days to several weeks or even months. The disease first manifests contractions (twitching) of muscles in the place of the infection. Then the spasms can spread throughout the body. Spasms are very painful, lasting from several seconds to several minutes. They can cause difficulty breathing, heart contractions, blood pressure.

yeah, it's more similar to something else

Now the tetanus Bacillus is a very common bacterium (she lives in Russia), but due to massive vaccination of the epidemic of tetanus does not occur. And even the survivors are not immune to the disease, without vaccinations, they can get tetanus again. Therefore, vaccination should be repeated after several years.

inhabited by dangerous bacteria?

These are just some of the bacteria that can be dangerous to humans. Some of them in large numbers . Probably many of you already know that the dirtiest items in the apartment are cutting Board and kitchen sponge. Scientists generally believe that they are real incubators of bacteria, because on the surface they feel great. So hand washing is necessary even at home and as often as possible. Well and keep clean products, of course.
