Exciting new research has revealed that humans have been utilizing bacterial weapons for centuries. Scientists from the University of California, Berkeley have discovered that a type of bacteria used by some Indigenous populations of the Northwest Coast of North America in the 18th century may have helped them to survive and even thrive in a hostile environment. This bacteria, known as “IDs,” was used to create a defensive weapon that was sprayed on enemies or rivals to cause infection and ultimately death. The findings suggest that humans have been utilizing bacteria as weapons for a much longer time than previously thought. The implications of this study could have far-reaching effects, as it could help us better understand the use of pathogens in warfare and the potential of harnessing bacteria for defense.
