Title: | The Impact of Bacterial Diet on the Migration and Navigation of 'Caenorhabditis elegans' | Contributor(s): | Rodger, S (author); Griffiths, B S (author); McNicol, J W (author); Wheatley, R W (author); Young, Iain (author) | Publication Date: | 2004 | DOI: | 10.1007/s00248-003-0201-1 | Handle Link: | https://hdl.handle.net/1959.11/5560 | Abstract: | Can diet have a significant impact on the ability of organisms to sense and locate food? Focusing on the bacterial feeder 'Caenorhabditis elegans', we investigated what effect preconditioning on a range of bacterial substrates had on the subsequent chemotaxis process involved in the nematode locating other bacterial populations. Remarkably, we found that 'C. elegans', initially fed on a diet of 'Escherichia coli' OP50, was significantly impaired in finding 'E. coli' OP50 populations, compared to other available bacterial populations (P < 0.001). We found similar results for another bacterial feeding nematode species, suggesting that a general "substrate legacy" may operate across a wide range of organisms. We discuss this important finding with respect to the variation in response exhibited within a given nematode population, and the impact nematode migration has on bacterial dispersal in the environment. | Publication Type: | Journal Article | Source of Publication: | Microbial Ecology, 48(3), p. 358-365 | Publisher: | Springer New York LLC | Place of Publication: | United States of America | ISSN: | 1432-184X 0095-3628 |
