Salmonella enterica strain SA20021456

Salmonella enterica strain SA20021456 is a gram-negative, microaerophilic bacterium characterized by its spirilla shape and chains or singles cell arrangement. This strain is a chemoorganotroph, indicating that it derives energy from organic compounds. It has two membranes and contains two replicons, which are critical for its genetic stability and replication. The optimal growth temperature for S. enterica strain SA20021456 is 37°C, placing it within the mesophilic temperature range. Despite its ability to live freely, it is host-associated, with a range of hosts that includes Homo sapiens, various birds (Gallus gallus, Columbidae), several mammals (Sus scrofa, Mammalia), and plants such as Solanum lycopersicum, Arabidopsis, and Hordeum vulgare. This strain is known to cause several health issues, including bacteremia, acute cholecystitis, and various forms of gastroenteritis. Its pathogenic potential makes it a significant concern in foodborne illness, with symptoms ranging from diarrhea to more severe systemic infections, such as typhoid fever and gallbladder empyema. The presence of flagella suggests a level of mobility, although it is noted that this strain exhibits no motility. This unique combination of traits contributes to its adaptability and survival within diverse ecological niches, demonstrating the complex interactions between pathogens and their hosts in both environmental and clinical settings.
