Bacteria with antibiotic resistant genes discovered in Antarctica, scientists say

Bacteria in Antarctica have been discovered with genes that give them natural antibiotic and antimicrobial resistance and have the potential to spread out of the polar regions, according to scientists in Chile.
Andres Marcoleta, a researcher from the University of Chile who headed the study published in the Science of the Total Environment journal in March, said that these "superpowers" which evolved to resist extreme conditions are contained in mobile DNA fragments that can easily be transferred to other bacteria.
Impact of climate change
"We know that the soils of the Antarctic Peninsula, one of the polar areas most impacted by melting ice, host a great diversity of bacteria," Marcoleta said. "And that some of them constitute a potential source of ancestral genes that confer resistance to antibiotics."

"It is worth asking whether climate change could have an impact on the occurrence of infectious diseases," Marcoleta said.

"In a possible scenario, these genes could leave this reservoir and promote the emergence and proliferation of infectious diseases."

Possible source of 'resistance gene'

Researchers found that the Pseudomonas bacteria, one of the predominant bacteria groups in the Antarctic Peninsula, are not pathogenic but can be a source of "resistance genes," which are not stopped by common disinfectants such as copper, chlorine or quaternary ammonium.

However, the other kind of bacteria they researched, Polaromonas bacteria, does have the "potential to inactivate beta-lactam type antibiotics, which are essential for the treatment of different infections," said Marcoleta.

It's been a good while, but this place has always been home. Thankful to be here.
Hi! I'm not as active on this account as I want to be. For one I tend to forget that this site exists until I check my email. Two, I'm currently in the process of building up a fine art site for Oklahoma black and native historical references. The references correlate with another site that will be a storytelling site that has not yet been produced.
Happy to be back and gaining more knowledge!
