Campylobacter jejuni subsp. doylei 269.97

Campylobacter jejuni subsp. doylei 269.97 is a Gram-negative, microaerophilic bacterium characterized by its spirilla shape and the presence of flagella, which contribute to its motility. It typically exists in chains or as single cells and is classified as a heterotroph, relying on organic compounds for its energy source. This organism demonstrates a mesophilic temperature range, with an optimal growth temperature of 0°C, indicating its adaptability to various environments. C. jejuni subsp. doylei 269.97 has a single replicon and is surrounded by two membranes, a feature typical of Gram-negative bacteria. It is nonsporulating and exhibits pathogenicity, which suggests its potential role in causing disease. The organism is free-living, indicating that it does not rely on a host for survival, and can inhabit multiple environments. The ecological significance of Campylobacter jejuni subsp. doylei 269.97 lies in its ability to thrive in diverse habitats while being pathogenic. This duality highlights the importance of understanding its life cycle and environmental interactions, as it can be a significant player in the epidemiology of foodborne illness. The accession number for this strain is NC_009707.1, which provides a reference for further genomic studies and insights into its pathogenic mechanisms.
