Scientists say that Bacteria with antibiotics, as opposed to genes, revealed in Antarctica

Discover antibacterial resistance genes in the bacteria of Antarctica. Findings suggest that these genes could potentially spread beyond the Polar Regions due to their adaptability to harsh environments. Learn more about the implications of climate change on infectious diseases.

In Antarctica, scientists discovered bacteria with antibiotic resistance genes.


From 2017 to 2019, researchers from the University of Chile collected samples from the Antarctic Peninsula.

Santiago Chilean researchers have revealed that the bacteria in the region of Antarctica contain genes that natural resistance through antibiotics does have the potential to spread beyond the Polar Regions.

According to the study, which was published in the journal Science of the Total Environment in March, these "superpowers" evolved to withstand harsh settings are restricted in the DNA segments that may be easily passed to other bacteria.

"We are acquainted with the terrains of Antarctic Peninsula, the polar sites most affected by means of melting glaciers," Marcoleta said. "And that some of them may have old genes that fight antibiotics."

From 2017 to 2019, researchers from the University of Chile collected samples from the Antarctic Peninsula."It's worth contemplating if climate change would affect the happenings of transmittable diseases," Marcoleta noted.


"It is possible that these genes may escape the reservoir and contribute to the genesis and spread of infectious diseases."

Researchers determined that Pseudomonas commonly found in soil, water, and plants  on the Antarctic Peninsula, are not hazardous but may be a cause of resistance to typical purifiers like chlorine, ammonium or copper

Polaromonas, on the other hand, has the "possibility to set off beta-lactam type antibiotics, which are essential for the treatment of many ailments."
