MRSA: Fear of a new pandemic! Horror bacteria in pigs on the rise

The antibiotic-resistant bacterial strain MRSA is not only spreading in pigs. Researchers have now warned that some form of the bacterium can infect humans and pose a threat.

Experts have seen intensive farming as a threat to human health for years. Because this sector will allow for further pandemics in the future, as various pathogens can also be transmitted to humans. This also includes the antibiotic resistant bacterial strain MRSA. Researchers now warn in a study that a form of this strain of bacteria is spreading more and more from animals to humans and could trigger a “hidden pandemic.” The study was published on the specialist portal “eVita“.

A new study warns of the transmission of antibiotic-resistant bacteria from pigs to humans

Over the past 50 years, MRSA type CC398 has become the predominant bacterial strain in livestock across the European continent. Because they came more and more often Antibiotics used in intensive farming, allowing the antibiotic resistant strain to survive. This is particularly evident in pig farming. “Historically high use of antibiotics may have led to the development of this highly antibiotic resistant strain of MRSA in pig farms,” ​​said Dr. Gemma Murray, one of the study’s lead authors, formerly at Cambridge Veterinary Medicine and now at the Wellcome Sanger Institute. Although fewer antibiotics are used in the EU, the MRSA type remains. An example makes this clear: in 2008, five percent of pig stocks were positive, in 2018 the value was 90 percent.

New pandemic? More and more people infected with the MRSA strain

As a result, human infections are also increasing, the scientists wrote. This in turn poses a “public health” risk, says Dr. Lucy Weinert, lead author of the University of Cambridge Veterinary Medicine study. She added: “Although human MRSA cases associated with farm animals represent only a small fraction of all MRSA cases in the human population, the fact that they are increasing is a worrying sign.”

MRSA infects humans due to three genetic elements in the genome. Two sections make the human body resistant to antibiotics. An element can bypass the immune system and thus adapt more quickly to its host.

WHO warns that MRSA is a health threat

MRSA (methicillin-resistant Staphylococcus aureus) was first diagnosed in humans in 1960. Bacterial strain infection is very difficult to treat due to its antibiotic-resistant nature. That is why WHO identifies MRSA as one of the greatest health threats to humanity.

Those affected do not always get sick after a MRSA infection. Healthy people have a lower risk of disease. The infection can be serious in people with weakened immune systems, elderly patients and infants.
