Salmonella enterica strain H3

Salmonella enterica strain H3 is a gram-negative, microaerophilic bacterium characterized by its spirilla shape and presence of flagella, facilitating motility. This strain is classified as a chemoorganotroph, deriving energy from organic compounds. It typically exists in chains or as single cells and is free-living, indicating its ability to survive independently in various environments. The strain is mesophilic, with an optimal growth temperature of 37°C, aligning with the typical body temperature of its hosts. S. enterica strain H3 is associated with a diverse range of hosts, including Homo sapiens (humans), Gallus gallus (chickens), and several plant species such as Solanum lycopersicum (tomatoes) and Arabidopsis. This broad host range indicates an ecological flexibility that allows the bacterium to thrive in multiple environments, including agricultural settings and within the human gastrointestinal tract. Clinically, S. enterica strain H3 is significant due to its association with various health issues, including bacteremia, acute cholecystitis, and several forms of gastroenteritis. It is a well-known agent of foodborne illness, often resulting from contaminated food sources and leading to symptoms such as diarrhea and systemic infections. Understanding the pathogenic potential and ecological adaptability of S. enterica strain H3 is crucial for public health efforts aimed at preventing salmonellosis and managing food safety.
