These are the diseases that are developing the most resistance to antibiotics


Organizations such as the WHO have been warning for years of the threat posed by the resistance to antibiotics that some bacteria are developing. This is a serious phenomenon, as it can cause diseases that we have hitherto had under control to become progressively more and more difficult to treat.

In fact, this is already the case for some of them, for which complications are becoming more frequent. These are the infections that are developing the most serious resistance to antibiotics.

A name that in the West seems to belong to the past, but which has never left developing countries. Now, the bacteria that cause it, Mycobacterium tuberculosis, are becoming resistant to the two most potent drugs that existed against it, complicating treatment and making the threat of outbreaks more present.

The case of Clostridium difficile is curious, as it is a pathogen that is naturally resistant to the most common antibiotics. Therefore, it is common for it to affect people after antibiotic treatments, as these do damage the rest of the intestinal flora that keeps it in check. Today, this resistance is expanding to increasingly include the two drugs that were effective against this infection.

Enterococci are a type of bacteria that naturally inhabit the human digestive tract and the inside of the vagina, but can sometimes cause skin infections, urinary tract infections, endocarditis and wound infections, in addition to their common habitats when their population gets out of control. Especially in hospital environments, where the evolutionary pressure exerted by antibiotics is greatest, some strains are becoming resistant to the antibiotic used against them (vancomycin).

Staphylococcus aureus has traditionally been a typical infection of hospital environments, but used to be treatable without much problem using methicillin. However, nowadays certain strains do not respond to treatment and can cause serious health problems. To make matters worse, in countries such as the United States, this infection is becoming increasingly common.

Neisseria gonorrhoeae infection is a very common sexually transmitted disease and typically, if detected and treated early, is not serious. The problem is that the treatments indicated are becoming significantly less effective against it, which has led agencies such as the U.S. Centers for Disease Control to update their guidelines on this disease.

Enterobacteriaceae is a family that includes many very common bacteria, such as the Klebsiella genus or Escherichia coli (E. coli). They mainly affect people with weakened immune systems, and some of their infections are becoming resistant to their typical antibiotics (carbapenems) and to most available antibiotics. In some cases, the diseases they cause can become fatal.
