Myxococcus xanthus does not respond chemotactically to moderate concentration gradients.
Using a number of approaches we were unable to demonstrate a chemotactic response of Myxococcus xanthus to a variety of defined and complex materials. These data in addition to a number of prima facie arguments considerably reduce the likelihood that M. xanthus possesses a mechanism for chemotactic behavior.
