Salmonella enterica strain H42

Salmonella enterica strain H42 is classified as a Gram-negative bacterium that exhibits a spirilla shape and demonstrates a microaerophilic oxygen requirement. It is a chemoorganotroph, deriving its energy from organic compounds. The bacterium is characterized by its arrangement in chains or singles and possesses flagella, although it is non-motile. Strain H42 thrives optimally at 37°C and falls within the mesophilic temperature range. It has a single replicon and is surrounded by two membranes, which is typical of Gram-negative bacteria. Salmonella enterica strain H42 is host-associated, with known hosts including Homo sapiens, Gallus gallus, and various plants and animals, such as Solanum lycopersicum, Arabidopsis, Hordeum vulgare, and Sus scrofa. This strain is implicated in several health-related issues, including bacteremia, acute cholecystitis, and various forms of gastroenteritis. Infections caused by this bacterium can lead to severe conditions such as systemic infection, disseminated disease, gallbladder empyema, and typhoid fever. The bacterium is also a known cause of foodborne illness, with symptoms ranging from diarrhea to intestinal inflammation. The ecological presence of Salmonella enterica strain H42 in diverse hosts, including plants and animals, underscores its role in food systems and public health. Its ability to infect both humans and livestock emphasizes the importance of monitoring its prevalence in food sources to prevent outbreaks of food poisoning and gastroenteritis.
