In Africa, we found new bacteria of the genus Salmonella. They are not afraid of antibiotics
All of us from early childhood know that dangerous germs can live in fresh fruits and vegetables. From our recent article about the importance of washing products you may remember that one of these dangerous bacteria are so-called salmonella. Penetrating into the human body, they cause fever, nausea and other unpleasant symptoms, and in severe cases can lead to dehydration and death. Caused by these bacteria is called salmonellosis disease and is usually treated with antibiotics, but a new type of bacteria that is not afraid of drugs was found in Congo, Africa.
more than 4 million people living in the Republic of Congo
In bacteria of the genus Salmonella there are many different types, which are applied to the human body different degrees of damage. For example, Salmonella typhi bacteria are the cause of typhoid fever - an infectious disease, accompanied by prolonged fever, headache, nausea and pain in the abdomen. Some patients may experience a rash, so in Russia the disease has also been known as "fever with spots."
The cause salmonellosis
One of the most common types is the so-called Salmonella Typhimurium. It is the cause of intestinal infections worldwide, but especially it affects people of Africa - in these areas recorded on a daily basis about 3, 4 million cases. However, the greatest danger for people present representatives Typhimurium type of ST313 group, because they are not afraid of most drugs.
Bacteria of Salmonella Typhimurium
Recently, scientists from the Belgian city of Antwerp took samples of salmonella in patients from three different cities in Republic of Congo. By their unpleasant surprise, some of the samples was observed resistance to antibiotics such as azithromycin and ciprofloxacin. Comparing the resistant bacteria with members of other groups, the researchers found that they appeared back in 2004 and gradually gained strength and stability.

Over time, salmonella have become so cunning that got rid of their bacterial flagellum, which helped them to move. Yes, they have lost their mobility, but in this form of human immune cells can not find them and destroy - this significantly increased their survival rates. In addition, they have lost their other abilities and in return received a high adaptability to the life within.
