1. What Else Can Scientists Do to Combat These Resistant Superbugs?

Researchers have recently put their heads together to find better ways to combat these superbugs. How? By using their own relatives against them. They’ve employed the use of CRISPR-Cas9 (via DW). What is that? A constructed gene-editing tool that infiltrates the interior of the harmful bacteria. It works as a pair of “genetic scissors,” cutting the DNA strands in the bacteria. That way, they can no longer thrive. The great thing about this method is that it doesn’t kill the good bacteria in the body the way broad-spectrum antibiotics do; it focuses only on harmful bacteria.

CRISPR-Cas9 have specific DNA sequence targets to know precisely what to look for and cut where that sequence is. This process is even more successful because bacteria share genetic material just by touching. With these changed sequences, the bacteria do all of the work for CRISPR-Cas9 (via DW). That means copying the new series and ultimately spelling their own demise. This has proven to be 99.9% effective against the targeted antibiotic-resistant bacteria in mice. In fact, it works by killing them in just under four days. However, the real problem lies in determining whether bacteria will further evolve to combat this technology. Thus, making them even harder to kill in the future.
