Discover more cases of antibiotic-resistant viruses in the United States

On June 27, US science officials announced that a second case of antibiotic-resistant viruses was recorded.

In a study published in the Journal of the American Society for Microbiology and Microbiology, microbiologists reported the discovery of a mutant gene MCR-1 or plasmid in the E. coli strain in a patient. live in New York.

This gene causes the E.coli strain to become a virus that is resistant to all antibiotics including Colistin - an antibiotic that is considered "the last save" in the treatment of serious diseases. .

Last month, US health officials discovered the first case of infection with all these antibiotics. However, the 49-year-old female patient living in Pennsylvania has recovered.

In the United States, antibiotic resistance has caused at least 2 million people to get sick and 23,000 people die each year.

MCR-1, located in a genetic information segment (DNA) of bacteria and can be transmitted to other bacteria through a number of species. According to scientists, the spread of the virus will be the beginning of a "nightmare" about a global epidemic of uninfected infections.

Scientists have begun to track the spread of the MCR-1 gene since the virus appeared in China, poultry and pigs in China in 2015. this bacterium.

Colistin is an older generation of antibiotics, introduced in 1950 to treat infections caused by E.coli, Salmonella and Acinetobacter bacteria. In the 80s of the last century, Colistin was banned from human use due to toxic effects on the kidneys, but is still widely used in livestock, especially in China. Scientists have warned that meat eaters who contain "greasy" bacteria are also at high risk of being infected with the bacteria themselves.

According to statistics, in the US alone, antibiotic resistance caused at least 2 million people to get sick and 23,000 people die each year. The abuse of antibiotics by doctors and patients and the widespread use of this drug in animal husbandry are becoming a painful problem, contributing to the current "antibiotic resistance crisis" .

Health experts recommend that people should limit the use of antibiotics if not necessary, while emphasizing the best way to prevent disease is to increase resistance, maintain cleanliness and consume food. hygienic.
