Resistant microbes. How do they survive? #003
People have become convinced that bacteria have the ability to develop incredible resistance. For example, they can form a cell wall that prevents the antibiotic from entering the bacterium, or change their own chemical composition, as a result of which the antibiotic loses its power. In addition, microbes are able to expel the antibiotic as soon as it gets inside, or simply disarm it by decomposing it into separate elements.
With the increased use of antimicrobials, resistant strains of bacteria have spread. Does this mean that you can forget about antibiotic treatment? No, at least not in most cases. If one antibiotic fails to destroy the infection, then another usually can. Although microbial resistance is a serious problem, it has recently been possible to combat it.
Resistance to various types of antibiotics
Scientists were shocked when they discovered that bacteria can exchange genes with each other. At first, it was thought that only bacteria of one species did this, but later the same resistance genes were discovered in bacteria of other species. Due to this exchange, microorganisms of different species have become resistant to many common medications.
In addition, research conducted in the 1990s proved that certain bacteria develop antibiotic resistance automatically. Even when only one antibiotic is used against them, they develop resistance to many natural and synthetic antibiotics.
A bleak future
Today, most antibiotics can still be successfully used to fight infections, but how effective will these medications be in the future? In the book "The Paradox of antibiotics" it was noted: "One should not hope that any infection will be able to be destroyed with the first available antibiotic." It goes on to say: "In some parts of the world, there are many types of antibiotics of choice, which means that there are simply no more effective ones... Patients are suffering and dying from diseases that were thought to have been wiped off the face of the earth 50 years ago."
Bacteria are not the only microorganisms that have developed resistance to medications. Viruses, fungi, and other small-sized parasites have a great ability to adapt. Among them, strains are emerging that negate all the efforts that have been made to invent and produce effective medicines. Жители в Серпухове получают доступ к казино через скачать Мелбет казино .
