Researchers: Antibiotic-resistant staphylococci come from hedgehogs

Prague – Hedgehogs are a natural carrier of antibiotic-resistant Staphylococcus aureus bacteria. The transmission of these bacteria to humans probably took place in the 19th century, so they did not develop until the rise in the use of antibiotics in human and veterinary medicine. This follows from the findings of an international team of scientists with Czech participation, said today the representatives of the Czech University of Life Sciences (CULS). Research study published prestigious magazine Nature.

“Hedgehogs have been found to be a natural carrier of resistant Staphylococcus aureus bacteria. Antibiotic-resistant bacteria were thought to have evolved only after the use of antibiotics in medicine on a large scale, but in this publication we have shown that it has developed in hedgehogs before. This is because they have fungi on their skin that produce substances very similar to penicillin, “Barbora Černá Bolfíková from the CULS, who participated in the research, told ČTK. According to her, these microscopic fungi secrete beta-lactam antibiotics, which caused methicillin-resistant staphylococci.

“Apparently sometime 200 years ago, it was transmitted to humans or pets and from humans. And since then it has been maintained in the human population. And with the advent of antibiotics, it has become very widespread,” she added. operates at the Department of Animal Husbandry and Food Technology in the tropics.

The research collected hedgehog skin swabs from all over Europe. Subsequently, among other things, he sequenced the genomes of bacteria. The research was conducted by experts from the Copenhagen Serological Institute, but researchers from Oxford University and a number of other institutions also collaborated on it. Pavel Hulva from the Faculty of Science of Charles University also took part in the research on behalf of the Czech Republic.

Černá Bolfíková wants to continue to address the issue. “We will definitely be interested in how it developed. There are two species of hedgehogs in the Czech Republic. We are interested in whether they differ in different pathogens in any way, if so, in what way and what it means for those hedgehogs,” she said.
