Some of the risks of bacteria for human is that they can develop diseases such as botulism, tuberculosis, salmonella or cholera. Bacteria are a type of unicellular micro organism, one of the simplest, smallest and oldest known to science.
They are prokaryotic cells lacking a nucleus, a vital part of many natural cycles (such as the nitrogen cycle), thanks to their ability to convert inorganic elements into organic elements, and vice versa..
A high number of bacteria are beneficial to the body, many of them are present in the body and are responsible for certain elemental processes such as synthesizing the food we eat.
There is, however, a small percentage of bacteria that fall into a group called bacteria pathogens.
A pathogenic bacterium is an agent of the infectious type capable of causing disease in humans. These bacteria are responsible for millions of deaths every year worldwide.
The harmful effects that a pathogenic bacteria can cause in the human body vary depending on the bacteria itself, in certain cases they can become fatal without proper treatment..
The risks of bacteria are mainly contracting different diseases, the best known are:
This disease, caused by the bacteria Clostridium botulinum, can be contracted by eating poorly talked about or poorly canned foods, usually vegetables and pork and fish.
It can also occur due to the direct penetration of the bacteria into the human body (for example, through an open wound).
The clinical picture of botulism includes difficulty in vision (double or blurred vision), vomiting, weakness and sometimes paralysis of the body.
It is a bacterial disease caused by the germ Mycobacterium tuberculosis. It mainly affects the lungs, although on some occasions it can develop in other areas, such as the digestive system..
It is spread through the air and causes the appearance of nodules in the affected area. If treatment is not received, tuberculosis causes death in patients.
The most common symptoms of this disease are mild fever, cough for a long period of time (more than 3 weeks), blood in sputum, and night sweats..
Tuberculosis is one of the ten diseases that causes the most deaths in the world each year.
It is a diarrheal disease that is caused by the bacteria Salmonella.
It is caused by the contact or ingestion of feces, or spoiled foods such as beef, poultry and especially eggs and their derivatives (cream, yogurt, mayonnaise).
Also handling animals such as reptiles and birds can cause contagion because the bacteria is present on their skins. Causes fevers, diarrhea, vomiting, and headaches.
Cholera, caused by bacteria Vibrio cholerae, is an infection that attacks the small intestine causing watery diarrhea and vomiting.
In the most extreme cases, the speed and frequency of the evacuations is capable of causing dehydration so suddenly, that it can lead to the death of the infected person if this is not treated quickly..
Its contagion occurs through the ingestion of water contaminated with fecal waste or through the consumption of decomposed fish and shellfish.
