Too much of a good thing: Extra genes make bacteria lethal

We, as most animals, host many different beneficial bacteria. Being beneficial to the host often pays off for the bacteria, as success of the host determines the survival and spread of the microbe. But if bacteria grow too much they may become deadly. In a new study published in the latest editi... Read More
