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.

Early combination treatment can prevent heart attacks and save lives

Patients who receive an add-on medication soon after a heart attack have a significantly better prognosis than those who receive it later, or not all.

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.
