Screening for mutants with phenotypic defects is a straightforward method for identifying genes that function in a given biological process. In this article we describe how to culture free living worms (e.g., Pristionchus pacificus) in the laboratory and show two different mutagenesis methods, EMS and TMP/UV.

Source: Morgan, E., et al. Selective Cleaning of Wild Caenorhabditis Nematodes to Enrich for Intestinal Microbiome Bacteria. J. Vis. Exp. (2021)This video demonstrates a protocol for isolating intestinal bacteria of interest from wild Caenorhabditis worms. The worms are first starved and washed to eliminate residual feeding bacteria from their surface and intestinal lumen while preserving the target microbes. After surface cleaning and multiple crawling steps, the worms are dissected to extract...

We describe a protocol of brightfield intravital microscopy for measuring dynamic neutrophil-endothelial cell interactions during neutrophil recruitment in response to the source of a neutrophil chemoattractant in vivo. Neutrophil intraluminal crawling, transendothelial migration and chemotaxis in mouse cremaster muscle tissue are visualized with time-lapsed video photography and tracked with ImageJ.
FAQs
Worm crawling distance reflects the coordinated output of several neuromuscular levels rather than one isolated cell type. Sensory neurons provide information, motor circuits organize movement, and body-wall muscles produce the physical crawling pattern. Measuring the resulting path connects activity across these components with an observable behavioral outcome, helping researchers relate neural function to whole-animal locomotion.
The observation period sets the time window over which movement is quantified, so it directly shapes the recorded distance. A defined interval allows researchers to compare locomotion across animals or experimental conditions using the same measurement basis. Changes observed under identical timing can therefore be interpreted in relation to mutations, injury, environmental conditions, or candidate compounds.
A reduced value can indicate impaired neuromuscular performance, but the measurement alone does not identify the affected level. Altered sensory activity, disrupted motor-circuit function, or reduced body-wall muscle performance could each change the behavioral result. This makes the assay useful for detecting a locomotor phenotype while encouraging follow-up analysis of the underlying cellular mechanism.
A typical measurement places a nematode on a surface such as an agar plate, establishes a defined observation period, and records the path traveled during that interval. The resulting path length becomes the behavioral value for analysis. Comparing measurements across experimental groups can reveal whether a genetic, neural, environmental, or chemical manipulation changes locomotion.
The observation period and movement surface should be kept consistent when groups are compared, because both define the conditions under which path length is recorded. Environmental conditions also require attention because they can alter locomotion. Standardizing these factors helps researchers attribute differences in crawling distance to the tested mutation, injury, compound, or other experimental condition.
This assay is useful when researchers need a relatively simple, noninvasive behavioral readout of altered locomotion. It can help characterize the effects of genetic mutations, neuronal injury, environmental conditions, and candidate compounds. Because the outcome is measured in an intact nematode, it provides a way to connect cellular or neural changes with neuromuscular performance at the whole-animal level.
