A team from Lund University in Sweden collaborated with Ukrainian microbiologists to study bacterial resistance in patients wounded in the war and treated in hospitals.
Recent results published in The scalpel Infectious diseases It showed that many patients had bacteria with significantly higher resistance to antibiotics.
“I have a very thick skin and have witnessed many situations involving patients and bacteria. However, I must admit that I have never encountered such resistant bacteria like this before,” says Christian Riesbeck, professor of clinical bacteriology at Lund University.
There was never any doubt that we could help when we were contacted by Dr. Oleksandr Nazarchuk, a microbiologist at a university in Vinnitsa, Ukraine, says Christian Rysbeck. Ukraine needed help to assess the extent of bacterial resistance to antibiotics among seriously injured patients in hospitals.
In addition to all the human suffering caused by the war in Ukraine, another battle is now being fought – an invisible war against resistant bacteria. This became clear when Christian Riesbeck and his fellow researchers analyzed patient samples from severely injured patients, many of whom had burns, in Ukraine. Patients became infected while in hospital, primarily due to overcrowded wards and destroyed infrastructure.
Samples were collected from a total of 141 war casualties, 133 adults injured during the war, and eight infants diagnosed with pneumonia. These patients were admitted to three different hospitals in Ukraine, where they received emergency surgeries and intensive care to treat their conditions.
“We observed that many Gram-negative bacteria showed resistance to broad-spectrum antimicrobial agents, including newly developed enzyme-inhibiting antibiotics that are not yet available on the market. Furthermore, approximately ten percent of the samples contained bacteria that showed resistance to The antibiotic of “last resort” is colistin. While we have encountered similar cases in India and China before, nothing compares to the extent of resistance observed in this study. “Up to six percent of all samples contained bacteria resistant to both,” says Christian Riesbeck. “Antibiotic we tested.”
He emphasizes that this clearly highlights the challenges posed by resistant bacteria in times of war. In particular, Christian Riesbeck expressed concern about the resistance shown Klebsiella pneumoniae Bacteria, because they have the potential to cause disease in individuals with healthy, well-functioning immune systems.
“This makes me very worried. It is rare for us to encounter Klebsiella With high levels of resistance, it was not what we expected. While isolated cases have been documented in China, the scale of this situation exceeds anything we have seen before. While many countries are providing aid and military resources to Ukraine, it is crucial to help it address this ongoing situation. “There is a clear risk of the spread of more resistant bacteria, and this threatens the entire European region,” says Christian Riesbeck.
