Campylobacter jejuni subsp. doylei strain NCTC11951

Campylobacter jejuni subsp. doylei strain NCTC11951 is a Gram-negative bacterium characterized by its spiral shape (spirilla) and microaerophilic oxygen requirement, indicating that it thrives in environments with reduced oxygen levels. This strain exhibits a unique cell arrangement, forming chains or existing as single cells, and it possesses flagella, which are essential for mobility. However, it is noted that this strain does not exhibit movement. As a heterotrophic organism, C. jejuni subsp. doylei relies on organic compounds for its energy, reflecting its role in various ecological niches. The strain is classified as mesophilic, indicating an optimal growth temperature at 0°C, with a temperature range suitable for growth that typically encompasses moderate environmental conditions. C. jejuni subsp. doylei has a single replicon and is characterized by a double membrane structure, which is typical of Gram-negative bacteria. Its biotic relationship is classified as free-living, suggesting it can thrive independently without reliance on a host organism. The ecological insight derived from these characteristics highlights the versatility of C. jejuni subsp. doylei in adapting to various habitats. Its microaerophilic nature and heterotrophic lifestyle allow it to occupy diverse environments where organic matter is available, potentially influencing microbial community dynamics and nutrient cycling in those ecosystems. The strain's accession number is NZ_LR134359.1, providing a reference for further genetic and genomic studies.
