Campylobacter jejuni subsp. jejuni strain 00-0949

Campylobacter jejuni subsp. jejuni strain 00-0949 is a Gram-negative, microaerophilic bacterium characterized by its spirilla shape and the presence of flagella, which contributes to its motility. This strain is a heterotroph, obtaining energy from organic compounds, and exhibits a unique cell arrangement, primarily found in chains and singles. It thrives in multiple habitats and is classified as mesophilic, with an optimal growth temperature of 0°C and a temperature range that supports its survival in varying environmental conditions. The strain possesses three replicons and is encased in two membranes, which is typical for Gram-negative bacteria. Its biotic relationship is free-living, allowing it to exist independently in the environment. C. jejuni subsp. jejuni strain 00-0949 has a diverse range of hosts, including Homo sapiens, Gallus gallus, Bos taurus, and other mammals and birds, indicating its adaptability and potential for zoonotic transmission. This bacterium is associated with numerous health effects, particularly gastroenteritis and various infections such as bacteremia and urinary tract infections. It is a significant cause of foodborne illnesses, enteric infections, and has been linked to Guillain-Barre syndrome (GBS), a serious autoimmune condition. The widespread presence of this strain in various hosts highlights its ecological significance and underscores the importance of monitoring and controlling Campylobacter infections to protect public health.
