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.

Ceanorhabditis elegans has been, and is still, used to great success as a model organism for studying a variety of developmental, genetic, molecular and even physical phenomena. In order to use C. elegans to its full potential, proper care and attention to the basic maintenance of this powerful organism is essential. In this video you will learn the basic housing and feeding requirements of C. elegans, how to correctly handle and manipulate worms using a worm pick and how to freeze and recover...

Drosophila melanogaster, commonly known as fruit flies, are a frequently used model organism for life science research. Although starting a collection of these critters may seem as easy as leaving a banana on your kitchen counter for too long, a productive fly colony in the lab requires careful husbandry and maintenance. This video demonstrates the necessary steps for maintaining a healthy fly stock. The overview begins with the preparation and storage of the yeast and sugar-containing media on...

All animal procedures described here must be conducted in accordance with institutional animal ethics guidelines and approved by IACUC. All procedures must follow the principles of the 3Rs—Replacement, Reduction, and Refinement—and must be performed by trained personnel. Introduction to C. elegans The nematode (roundworm) Caenorhabditis elegans, commonly known as C. elegans, is a widely used non-vertebrate animal model for studying fundamental biological processes. Because many cellular and...

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...
FAQs
Temperature is one of the environmental variables that must remain controlled because shifts can alter physiological stability and disturb normal development. If conditions vary during an experiment, observed differences in growth, regeneration, behavior, or reproduction may reflect water conditions rather than the treatment being studied. Stable temperature therefore helps researchers attribute developmental outcomes to the intended experimental factors.
pH and dissolved oxygen help determine whether the water remains physiologically suitable for the worms. Changes in either condition can contribute to environmental stress and make developmental observations less consistent. Monitoring these variables alongside temperature gives researchers a clearer way to maintain stable experimental conditions and reduces the possibility that altered water chemistry will confound measurements of development or behavior.
Clean water and control of waste buildup help preserve conditions in which worms remain physiologically stable. Accumulated waste introduces additional environmental variation and may interfere with observations of growth, regeneration, behavior, or reproduction. Managing cleanliness is therefore relevant not only to animal welfare but also to the reliability of developmental biology experiments and comparisons between experimental groups.
A single measurement describes conditions at one moment, whereas consistent maintenance limits variation throughout the study. Stable conditions make it less likely that developmental changes result from fluctuations in temperature, pH, dissolved oxygen, cleanliness, or waste. This consistency strengthens reproducibility because researchers can compare observations across experiments with greater confidence that environmental differences did not drive the outcome.
The workflow centers on monitoring the water and adjusting conditions when needed. Researchers assess temperature, pH, dissolved oxygen, cleanliness, and waste buildup, then correct unsuitable conditions to keep the environment stable. Maintaining these factors as part of an ongoing process supports worm health and helps preserve the validity of observations collected during developmental experiments.
Well-maintained water supports reliable study of several outcomes, including growth, regeneration, behavior, reproduction, and responses to experimental treatments. In developmental biology, these observations can relate to tissue formation and broader organismal development. By reducing environmental variation, water maintenance helps distinguish biological responses from effects caused by unstable conditions and improves the reproducibility of findings.
