Protocol for isolating single species of bacteria with swarming ability from human feces.

ABSTRACT

Understanding the specific movements of bacteria isolated from human feces can serve as a novel diagnostic and therapeutic tool for inflammatory bowel disease. Here, we present a protocol for a microbial swarming assay and to isolate the bacteria responsible for swarming activity. We describe steps for identifying bacteria using MALDI-TOF mass spectrometry and whole-genome sequencing. We then detail procedures for validating findings by observing the same swarming phenotype upon reperforming the swarming assay. For complete details on the use and execution of this protocol, please refer to De et al.1.
