Secondary changes allow spread of oseltamivir resistant influenza virus

The influenza virus neuraminidase (NA) protein is required for virus release from the cell, a property exploited by the antiviral drugs oseltamivir (Tamiflu) and zanamavir (Relenza). During clinical testing of oseltamivir in 2001, some individuals shed drug-resistant viruses with an amino acid c... Read More

Uncovering Beauty in Proteins to Fight the Pneumococcal Fratricides

From time to time, we dip into the microbiology blog by César Sánchez, Twisted Bacteria, and, with his permission, "borrow" a post such as this one about pneumonia and pneumococci, fratricide at the cellular level, and a pretty protein. And there's a video too!
