New antibiotic resistant bacteria found
In the same family as salmonella and E-coli bacteria, a hitherto unknown antibiotic-resistant bacterium has been found in a patient in Sweden. The finding allows doctors to avoid broad-spectrum antibiotics that drive the development of resistant bacteria.
The antibiotic-resistant bacterium, which is now proposed to be named Scandinavium goeteborgense, was already found in 2014 in a leg ulcer in a patient at Kungälv hospital.
This bacterium is believed to have caused infections both before and after it was found. The species belongs to the same family as E-coli bacteria and salmonella and is the first in its genus.
An infected wound
It is essential for doctors to find out which bacteria is causing the infection so that the right antibiotic can be prescribed. It can have severe consequences for a patient if incorrect treatment is used.
The researchers were able to isolate the bacteria from the sample taken from the patient’s infected wounds, but it did not stop there. Still, rather extensive analyzes were required for them to determine the species.
What the researchers’ path to the discovery of this bacterium looked like can be read in a study published in the journal Frontiers in Microbiology.
The researchers were then able to classify the new species, which turned out to belong to a whole new genus of bacteria.
More specific antibiotics
– This is a clear example of how important it is to be able to identify the direct causes of an infection. If the bacteria are precisely defined, the doctor can prescribe specific antibiotics and need not rely on broad-spectrum antibiotics, says Francisco Salvà Serra, in a press release. He is a researcher at the Center for Antibiotic Resistance Research, CARe, at the University of Gothenburg and is one of two first authors of the study.
The problem with so-called broad-spectrum antibiotics is that they drive the development of antibiotic resistance in bacteria, but also disease bacteria.
This leads to worse opportunities to treat infections.
