A (very!) brief overview of inflammation and your immune system

Another video from LinkedIn, this video from Pfizer shares how the immune system creates an inflammatory response and how the response works against the body in auto-immune disorders. The video is less than 5 minutes, and is only the most cursory of discussions, but it's a decent start and might be a semi-decent way to review these concepts if you need it.

Using Viruses to Fight Bacteria?

In Tbilisi, Georgia (the country, not the state), Dr. Revaz Adamia is trying something different in the war against bacteria: instead of using antimicrobial drugs, he's treating infections with a special class of viruses instead. Why use viruses? The class in use, bacteriophages, target only bacteria, not the human infected. As a result, the virus infects and kills the infection that was making the patient sick. When the bacterial infection is gone, the virus, now without a host, dies off.

This solution is an alternative to the increasing problem of antimicrobial resistance. Many bacteria are increasingly resistant to the drugs used to treat patients infected with them. The most well-known case of resistance is MRSA, or Methicillan-resistant Staphylococcus aureus, a bacteria that frequently causes skin and respiratory infections or food poisoning. Resistant bacteria no longer respond to the drugs once used to treat infections, making treatment of patients increasingly difficult.
