摘要: Le chimiotactisme de Caenorhabditis elegans vis-a-vis plusieurs especes bacteries a ete etudie dans des boites Petri specialement concues. Toutes les testees ont un effet sur le mode migration nematodes et degre modification depend bacteries. Acinetobacter calcoaceticus var. anitratus, Enterobacter amnigenus, E. cloacae, Pseudomonas maltophilia Serratia liquefaciens sont plus attractifs qu'Escherichia coli fluorescens biovar reactans. Bacillus cereus, B. thuringiensis and sp. n'ont qu'une faible influence la migration. Les colonies bacteriennes jeunes (24-48 h) attractives que âgees (96-192
