Bacterial resistance to antibiotics is becoming a real threat to the health of all the inhabitants of the earth.
The human being in its progressive expansion across the globe, had to ensure the safety of its species against the rest of the species, both macroscopic and microscopic. Bacteria, protozoa, viruses, organisms that we cannot see with the naked eye but that can cause us greater evil than a chase by a hungry leopard. In the case of bacteria, the development of antibiotics allowed us to end a huge number of diseases, until our times.
An antibiotic can kill the bacteria in many ways, but there is a very limited variety of antibiotics.. There are some that inhibit the proteins of the bacterial wall making their contents free, destroying the bacteria, others boost our immune system to recognize the invader and reject it or break into some cellular mechanism that the bacterium uses to interact with our physiology or metabolism.
The antibiotic abuse in confined spaces by the livestock industries or the self-medication in populations where acquiring antibiotics is so close at hand, they are facilitating the emergence of bacteria resistant to the reduced variety of antibiotics that we have to deal with.
Detected in a 49-year-old woman a bacterium resistant to all antibiotics
A 49-year-old woman comes to a health center in the United States due to a urinary tract infection, and what she would never imagine is that she carried a bacterium capable of resisting all antibiotics to date. The strain in question is none other than the well-known E. coli, which proved to be able to survive colistin, an antibiotic that is only used with those bacteria that cannot be treated with conventional antibiotics and that in Spanish we could know how nightmare bacteria.
The teacher of the School of Medicine At Harvard University and microbiology, Gail Cassel warns that we should not take this fact lightly, we must trace the focus of infection and the appearance of the strain, identify if there are any more cases and know in more detail what mechanism the bacteria to overcome these antibiotics.
What would we be without antibiotics?
The case of this lady may not be the only one, and in the coming years the frequency with which the antibiotic resistant strains will appear could become such that it is estimated that by 2050 they will cause more than 10 million deaths worldwide.
An antibiotic is like an exam or an entrance test for the bacteria. Only the best prepared will manage to pass, and the reality is that until now, none have been able to overcome the difficult exams. The problem lies in the dose of antibiotics they give in the livestock industries, where countless animals are clustered in a very small space and are offered a generous dose. In this way we will be examining so many bacteria, that finding one that manages to pass the test will no longer be crazy.
The who It has already started an action plan and specific pharmaceutical companies have adapted their antibiotic development processes to overcome these resistances and manage the intellectual property of the antibiotics that will renew the current ones.
