Genome sequences from "Mass mortality at penguin mega-colonies due to avian cholera confou

Antarctic Adélie penguin colonies experienced a mass mortality event in the austral summer of 2023/2024. This dataset contains 52.6 MB of FASTA-formatted genomic sequences for the Pasteurella multocida strain identified as the cause, collected from 49 carcasses in the Danger Islands archipelago. The data was authored by Matteo Iervolino and shared under a CC-BY-4.0 license on figshare in May 2026.

Use Cases

• Phylogenetic analysis of Pasteurella multocida strains based on the retrieved genomic sequences.
• Comparative genomics to understand virulence factors in Antarctic wildlife pathogens.
• Surveillance and differential diagnosis support for future mortality events in Antarctica.
• Tracking the spread and evolution of infectious agents in the Southern Ocean region.

Strengths

• Contains the complete genomic sequence of the specific Pasteurella multocida strain responsible for the outbreak.
• Data is derived from samples collected from 49 individual carcasses across multiple species.
• Shared under a permissive CC-BY-4.0 license for open reuse.

Limitations

• Row count and specific sample-level metadata are unknown, limiting suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Data may reflect geographic and temporal bias inherent to the single outbreak event.
