Salmonella enterica subsp. enterica serovar Worthington strain

Salmonella enterica subsp. enterica serovar Worthington is a microaerophilic, Gram-negative bacterium characterized by its spirilla shape. This strain is primarily host-associated, indicating a significant relationship with animal hosts, which are likely reservoirs for transmission. As a chemoorganotroph, it utilizes organic compounds for energy, adapting to its environment effectively. The cellular arrangement of S. enterica Worthington includes both singles and chains, and it possesses flagella, which are structures that enable motility in some bacterial species. However, this specific strain is noted to be non-motile, suggesting that while it has the potential for movement, it may not actively utilize this capability in its ecological niche. With an optimal growth temperature of 37°C, this bacterium thrives in mesophilic conditions, which is typical for many pathogens that infect warm-blooded hosts. The strain has a total of three replicons and is characterized by having two membranes, a feature common in Gram-negative bacteria. The ecological insight provided by the traits of S. enterica Worthington highlights its role as a free-living organism within host-associated environments. Its adaptations, such as being microaerophilic and utilizing organic compounds, suggest it plays a role in the microbiota of its hosts, potentially influencing both health and disease dynamics. Understanding these traits can inform strategies for managing infections caused by this serovar and the broader implications for public health related to Salmonella infections.
