Penicillin News and Research

RSS

Penicillin (sometimes abbreviated PCN or pen) is a group of antibiotics derived from ''Penicillium'' fungi. Penicillin antibiotics are historically significant because they are the first drugs that were effective against many previously serious diseases such as syphilis and Staphylococcus infections.

Targeted bacteriophages offer standardized and scalable GI therapy

In a new study, researchers at the University of Copenhagen have been cultivating 'good viruses' from feces. The goal is to replace fecal capsules now being used in so-called fecal transplants. Their new technique has shown potential in studies with mice and the hope is that it will improve this life-saving treatment through standardization and pave its way toward mainstream medicine.

New tool spots drug-resistant bacteria before treatment

Penicillin was hailed as "the silver bullet" when it was discovered, as it had the unprecedented quality of being able to kill disease-causing bacteria without harming the human body. Since then, a multitude of other antibiotics have been developed that specifically target a wide range of bacteria; but the more often they are used, the greater the risk that antibiotic-resistant strains will arise.
