Campylobacter jejuni strain SO-73 61

Campylobacter jejuni strain SO-73 61 is a Gram-negative, microaerophilic bacterium characterized by its spirilla shape and chains or single-cell arrangement. It is heterotrophic, indicating that it derives its energy from organic compounds. The strain has a mesophilic temperature range, thriving at an optimal temperature of 0°C, and it possesses two membranes, which is typical for Gram-negative bacteria. This organism is free-living and has been identified in multiple habitats, suggesting adaptability to various environmental conditions. It is equipped with flagella, enabling motility, although it is noted that within this context, mobility is categorized as "No." C. jejuni strain SO-73 61 has a diverse set of hosts, including Homo sapiens (humans), Gallus gallus (domestic chickens), Bos taurus (cattle), Ovis aries (sheep), and several others, including domesticated animals like Canis lupus familiaris (dogs) and Felis catus (cats). This extensive host range highlights its potential for zoonotic transmission and its role in foodborne infections. The health effects associated with this strain are significant, as it can cause a variety of illnesses, including gastroenteritis, bacteremia, and even complications such as Guillain-Barre syndrome (GBS). These associations emphasize the importance of understanding the ecology and biology of C. jejuni strain SO-73 61, especially in the context of public health and food safety, where it is a notable pathogen in enteric infections.
