Superbugs That Resist Antibiotics Can Evolve in 11 Days | I Contain Multitudes



Antibiotics like penicillin have a critical role in medicine, but using them is not a decision to be taken lightly.

Before the discovery of penicillin and other antibiotics, a cut on your knee or an ear infection could kill you. In 1928, a physician named Alexander Fleming found that a mold in one of his petri dishes was killing the bacteria he was trying to grow. This strain of mold formed the basis for one of the most significant medical discoveries in history: penicillin. Antibiotics soon became lifesavers, and so precious that unused penicillin was reclaimed from patients’ urine to give to others. However, even back then, Fleming knew that bacteria could become resistant to penicillin. In this episode, Ed Yong explains how serious the situation can become: “Bacteria have always been evolving ways of resisting the things that try to kill them. And now the overuse of antibiotics is exacerbating that problem.” Ed looks at shocking new footage of mutating bacteria thriving in antibiotics a thousand times stronger than can kill their non-superbug ancestors.

    Good show, but I want to know. What ARE viruses? You don't have to make a video and some commentor may explain.

    Great video, thanks. Let's not forget that although Fleming discovered penicillin, it was actually Florey and Chain in the midst of WWII that turned it into medicine. All three shared the Nobel prize in 1945.

Discover MICRO SWITCH Heavy-Duty Limit Switches | Honeywell Productivity




Find out how MICRO SWITCH HDLS Series Heavy-Duty Limit Switches are designed with enhanced durability, making them ideal for many indoor and outdoor applications where they may be subjected to shock or vibration from equipment, temperature extremes, dust, splashing water, coolant, and/or hose-directed water.

For over 80 years, Honeywell has been designing MICRO SWITCH limit switches. Today, our HDLS Series Heavy-Duty Limit Switches are the industry standard for more reliably indicating position to system controls. Their rugged design provides more consistent actuation at the same set-point and an extended life up to 50 million actuation cycles.

Honeywell’s MICRO SWITCH Heavy-Duty Limit Switches’ modular construction allows for a wide variety of actuator styles, operating heads and electrical circuitry options. The plug-in versions reduce downtime on production lines with high actuation rates as replacement of the switch is accomplished in seconds. The base receptacle contains all the wiring and conduit connection while the switching component with operating head easily assembles to the base and is attached with two screws.
