Rice study examines how bacteria acquire immunity
Date:9/15/2010

er, so there's been more selective pressure applied to that spacer. Because bacteria that contain the dominant viral strain in their CRISPR are more likely to survive than those that don't, they tend to squeeze out their neighbors that are more vulnerable. At position N, the farthest way from position one, selection has been at work the longest, so the genes we find there were the most common and the ones that tended to afford the most overall protection to the organism."

In addition to interest from biotechnology firms, Deem said the workings of the CRISPR are of interest to drugmakers who are investigating new types of antibiotics.
