Using the bacterium Streptococcus thermophilis, a team led by Philippe Horvath at the Danish food ingredient company Danisco, integrated bacteriophage sequences into "clustered regularly interspersed short palindromic repeat" (CRISPR) regions to generate phage-resistant bacterial strains. "They directly confirmed the prediction," says Eugene Koonin, a computational biologist at the US National Center for Biotechnology Information.
