Bacterial resistance to antibiotics

The image illustrates the complex interactions described in your summary, and shows the complex choices that bacteriophages make between aggression and dormancy within their bacterial hosts, which are influenced by environmental cues and the health of the host. This represents the sophisticated mechanisms at work in bacterial and viral interactions as revealed by the study. Credit: The Science website via DALEE

How do viruses decide whether to stay friendly?

This is how the decision-making mechanism of viruses works

Injection of honey prevents infections in horses

The results of a study conducted at the Veterinary Hospital of the Hebrew University show that the treatment significantly reduced the rate of infections from 32% to 8%. It is possible that the use of honey could reduce or replace in the future, the use of antibiotics both in animals and among people

Substances that allow the body to eliminate the predatory bacteria completely

Treating the host and not the bacteria is a breakthrough for the development of innovative and effective treatments that do not cause the development of resistance to antibiotics

A mechanism has been revealed by which "good" viruses eliminate "bad" bacteria and stop their culture

  • One response
Researchers from Tel Aviv University discovered a process in which a "good" virus manages to selectively destroy the DNA of the "bad" bacteria, thus stopping the reproduction of the bacteria. The discovery may help in the development of treatments against antibiotic-resistant bacteria, which cause infectious diseases

Do not rush the medicine

A new report by the Ministry of Health found that strengthening the regulation and supervision of veterinary preparations is an important way to reduce the use of antibiotics in farm animals, which is one of the main causes of bacterial resistance to antibiotics

Prof. Omri Koren from the Faculty of Medicine of Bar-Ilan University in the Galilee, together with researchers from around the world found that children who received antibiotics in the first two weeks of life were less tall compared to their peers. The phenomenon was observed only in boys, not in girls

This is how bacteria turn the cells of the immune system into an all-inclusive hotel: bacteria swallowed by macrophages sometimes succeed not only in surviving but even thriving inside them, as if they were incubators that help spread the infection in the body - and not soldiers in the service of the immune system
