Aug 21, 2020 · The strength of C. elegans as a model organism for microbiome research is its ability to conduct high- throughput experiments with a gnotobiotic organism and to explore the complex cause and effect relationship between presence and absence of a microbial species and a phenotype reflecting good or bad health. In fact, the microorganisms that ...

2.1. Small size. Despite the numerous advantages, there are several problems in the use of C. elegans as a model system for the study of aging ( Table 2). First and foremost among these are the small size and thus great difficulty in obtaining biochemical amounts of nematodes at later ages.A particularly useful model organism is Drosophila melanogaster (D. melanogaster), a type of fruit fly.
