Salmonella enterica strain H43

Salmonella enterica strain H43 is a Gram-negative bacterium characterized by its spirilla shape and microaerophilic oxygen requirement. This strain is a chemoorganotroph, utilizing organic compounds for energy. It is known to exist in chains or singles and possesses flagella, although it is non-motile. H43 is primarily associated with various hosts, including Homo sapiens, Gallus gallus, and other metazoans, as well as several plant species such as Solanum lycopersicum and Hordeum vulgare. The strain has been implicated in several health effects, including bacteremia, acute cholecystitis, and various forms of gastroenteritis, such as Salmonellosis and acute gastroenteritis. The bacterium can lead to systemic infections and other severe conditions like gallbladder empyema and typhoid fever. Strain H43 thrives at an optimal temperature of 37°C, within a mesophilic temperature range. It contains a single replicon and is surrounded by two membranes, typical of Gram-negative organisms. Notably, H43 does not form spores, indicating its reliance on host environments for survival. Understanding the ecology of Salmonella enterica strain H43 reveals its role in foodborne illness, particularly in relation to its diverse host range that includes not only humans but also livestock and various plants. The ability of this strain to cause systemic infections underscores its significance in public health and food safety, necessitating continued monitoring and research into its transmission and pathogenicity.
