Scientists from the University of Sheffield in the UK discovered through research that bacteria The bacteria that cause pneumonia have a mechanism called an “evolutionary gateway” that makes them resistant to the effects of antibiotics.
An evolutionary gateway is a set of genes that enable pneumocytes to adapt to changes in their environment. These encode proteins that help pneumonia cells survive adverse conditions, such as exposure to antibiotics.
This important advance in understanding how antibiotic resistance occurs will allow scientists to better predict which strains of pneumonia will become highly resistant in the future, giving them time to implement control measures that can help save patients’ lives.
mutated pneumonia cells
The researchers found that pneumonia cells with mutations in evolutionary pathways were more likely to become resistant to antibiotics. These mutations allow pneumocytes to evade the effects of antibiotics, leading to changes in the expression of genes associated with antibiotic resistance.
This research has important implications for developing new strategies to combat antibiotic resistance. Scientists can now develop treatments that block the activity of these genes.
Lead author Dr Andrew Fenton from the School of Biological Sciences at the University of Sheffield said: “Pneumonia is a dangerous and deadly infection Effective antibiotic therapy is critical to patient care. However, as antibiotics advance, their effectiveness is increasingly threatened. Over time, the bacteria that cause pneumonia can become resistant to antibiotic treatments.
“This study found that when bacteria become resistant to antibiotic treatment, genetic scars are left on the bacterial genome. This is a major advance in understanding how resistance occurs and how we can predict it.
“If we understand the emergence of antibiotic resistance, then we will be able to predict which bacterial strains become more dangerous. This will give us time to implement control measures to stop their spread and save patients’ lives.”
Bacteria can become resistant by exchanging genes
In addition to the Sheffield University study, other researchers have identified other evolutionary pathways that contribute to bacterial resistance to antibiotics. For example, a study published in the journal Cell found that bacteria can develop resistance to antibiotics by exchanging genes with each other. This process is called horizontal gene transfer and can occur between bacteria of the same species or between bacteria of different species.
Another study published in the journal Science found that bacteria can become resistant to antibiotics by changing their metabolism. This process, called metabolic evolution, allows bacteria to take advantage of nutrients that are less susceptible to antibiotics.
Antibiotic resistance is a growing public health problem. Researchers are working hard to combat it, so it’s important to understand how bacteria develop effective strategies to avoid this behavior.
Research is just the first step
The University of Sheffield research is a major breakthrough in understanding antibiotic resistance in pneumonia cells. The discovery of an evolutionary portal provides new insights into how pneumonia cells develop antibiotic resistance.
It should be taken into account that this study is only a first step in understanding antibiotic resistance in pneumocytes. More research is needed to understand how evolutionary gateways interact with other factors that contribute to antibiotic resistance.
