University of Otago researchers have contributed to an international study which helps improve the understanding of bacteria and viruses. Published recently in the international science journal, Nature, the study reveals how bacterial immune systems can be harmful for their hosts, and why they are not found in all bacteria. Researchers at the University of Exeter in the UK, with support from the University of Montpellier in France and the Otago team, made the suprising finding that existing CRISPR anti-viral immunity was often a disadvantage to the bacterium when infected by certain viruses.
