Salmonella enterica strain H15

Salmonella enterica strain H15 is a Gram-negative, microaerophilic bacterium characterized by its spirilla shape and the presence of flagella, although it exhibits no mobility. This strain is a chemoorganotroph, utilizing organic compounds as its energy source. It typically exists in a host-associated habitat, demonstrating a free-living biotic relationship. The optimal growth temperature for S. enterica H15 is 37°C, placing it in the mesophilic temperature range. It possesses a single replicon and has a double membrane structure. S. enterica strain H15 is known to infect a variety of hosts, including Homo sapiens (humans), Gallus gallus (domestic chickens), and other Metazoa, alongside various plant species such as Solanum lycopersicum (tomato) and Hordeum vulgare (barley). This diversity in hosts highlights its ecological adaptability. Clinically, S. enterica strain H15 is associated with several health effects in humans, including bacteremia, acute cholecystitis, and various forms of gastroenteritis, which can lead to systemic infections. The strain is implicated in foodborne illnesses, including food poisoning, and can cause severe intestinal inflammation and disseminated disease. The presence of S. enterica in both animal and plant hosts underscores its potential role in the food chain and the importance of monitoring this pathogen in agricultural and clinical settings to prevent outbreaks of salmonellosis and related diseases. Understanding the host interactions and environmental conditions that favor its proliferation can aid in developing strategies for disease prevention and control.
