Gut Yeast Effects on Chill Coma Recovery in Drosophila melanogaster

Data for "Gut yeasts accelerate chill coma recovery in Drosophila melanogaster" by Yanira Jiménez-Padilla, published on figshare in April 2026. The dataset contains experimental results measuring chill coma recovery time (CCRT) in flies under different gut microbial conditions, including axenic, native microbiota, and gnotobiotic flies mono-associated with specific live or heat-killed yeast species. The data supports findings that live yeast symbionts can rapidly and sex-specifically rescue cold tolerance deficits.

Use Cases

• Analyzing the effect of specific yeast species (Lachancea kluyveri, Pichia kluyveri, P. nakasei, Saccharomyces cerevisiae) on cold tolerance based on chill coma recovery time measurements.
• Investigating sex-specific differences in microbial effects based on the description's finding that the rescue effect was restricted to female flies.
• Studying dose-dependency and temporal dynamics of symbiotic interactions based on the described rapid effect occurring within 48 hours.
• Comparing the functional role of live versus heat-killed microbes based on the experimental conditions described.

Strengths

• Data is derived from a controlled experimental design with distinct microbial conditions: axenic, native microbiota, and gnotobiotic mono-associations.
• Includes measurements for multiple yeast species (Lachancea kluyveri, Pichia kluyveri, P. nakasei, Saccharomyces cerevisiae) and both live and heat-killed treatments.
• Published under a permissive CC-BY-4.0 license, allowing reuse and redistribution.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for large-scale analysis.
• The dataset is small (453.0 KB), indicating a limited scope likely focused on the core experimental results.
