Wykorzystanie danych dotyczących pojedynczego robaka do ilościowego określenia niejednorodności w interakcjach Caenorhabditis elegans z bakteriami

Overview

This protocol outlines a medium-throughput method for quantifying bacterial load in individual Caenorhabditis elegans. Following a series of preparatory steps, including cold paralysis and surface bleaching, this technique employs mechanical disruption in a 96-well format, enabling effective collection of data from large numbers of worms.
