The article I read this week was called “A new gel could help in the fight against deadly, drug-resistant superbugs” by Maria Temming (https://www.sciencenews.org/article/new-gel-could-help-fight-against-deadly-drug-resistant-superbugs?tgt=nr). This article talked about antibiotic and antibiotic resistant bacteria studies and one microbiologist at Emory University School of Medicine in Atlanta, David Weiss, although he was not actually involved in the work. Recently, a new gel was tested on human skin, as well as mice, and came back with exciting results.
Apparently, the medicine was able to eliminate from wounds a “strain of Staphylococcus aureus that is resistant to methicillin and other antibiotics, and antibiotic-resistant Acinetobacter baumannii”. Those two microbes are huge problems in many hospitals, causing serious infections. The main ingredient of this gel is called SAAP-148. It’s a chain of amino acids. It was found by Netherland researchers when they used a bacteria-fighting peptide normally found naturally in humans. Collagen is a protein made up of a long arrangements of amino acids formed like a chain. When this collagen breaks down, shorter segments of amino acids are made.
These tiny proteins and active molecules are referred to as peptides. This prevents the formation of biofilms, a slime that protects bacteria against antibiotics. In addition to this, after a few weeks, as is usual, the microbes didn’t develop a resistance SAAP-148. Starting in 2018, the effects of this gel put into practice on humans and studies. The article includes a digitally created image of the biofilms.This topic relates to health science and technology, and I chose it because it such a new discovery, right in the beginning of the year, and it addresses an important issue.
If this is taken further it will prove beneficial to hospitals all over the world, and their hopeful patients. People are wounded everyday, and in turn, infected. This could prevent that, so it’s essential that it continues being studied. As this is studied, it should be shared and advertised, so it can be put to good use.
