The chemical-in-plug bacterial chemotaxis assay is prone to false positive responses
Abstract Background Chemical-in-plug assays are commonly used to study bacterial Baby Washcloths chemotaxis, sometimes in the absence of stringent controls.Results We report that non-chemotactic and non-motile mutants in two distinct bacterial species (Shewanella oneidensis and Helicobacter pylori) show apparent zones of accumulation or clearing ar
