The World Health Organization (WHO) published a list of 15 bacteria that it considers a threat to human health due to their growing resistance to antibiotics and called for the development of new treatments.

The list is an update of the one made in 2017 and, with this publication, the WHO warns once again about the danger of the growing antimicrobial resistance of certain pathogens.
According to the WHO, antibiotic resistance causes about 1.27 million direct deaths annually and contributes to another 4.19 million deaths.
The 15 bacteria are classified into three priority categories (medium, high and critical), with the WHO placing four pathogens in the latter, the most urgent: acinetobacter baumannii, Mycobacterium tuberculosis and two types of enterobacteria resistant to treatment with the carbapenem and cephalosporin antibiotic classes.
"[These bacteria] Represent major global threats due to their high impact and their ability to resist treatments and transmit this resistance to other bacteria", the organization highlighted in a statement.
High-priority bacteria include salmonella and shigella, with a high incidence, according to the WHO, in developing countries, and others that frequently cause infections in places where health services are provided, such as pseudomonas aeruginosa or staphylococcus aureus.
Other bacteria on the list pose challenges to health systems, including persistent infections and multiple antibiotic resistance, which require research and public health interventions, the WHO highlights.
"Since the list was first published in 2017, the threat of antimicrobial resistance has intensified, undermining the effectiveness of numerous antibiotics and jeopardizing many advances in modern medicine", warned the head of the WHO's antimicrobial department, Yukiko Nakatani.
Antimicrobial resistance occurs when bacteria, viruses, fungi or parasites stop responding to drugs, worsening diseases and increasing the risk of contagion, mortality and severity of certain pathologies, a problem that is partly caused by the misuse of antibiotics in many patients.
A recent WHO report revealed that during the covid-19 pandemic there was excessive use of antibiotics by hospitalized patients with this disease, which may have exacerbated antimicrobial resistance.
Although only 8% of hospitalized patients with covid-19 also had bacterial infections that required antibiotics, these drugs were prescribed to three out of four patients (75%).
