Salmonella enterica subsp. enterica serovar Senftenberg str.

Salmonella enterica subsp. enterica serovar Senftenberg is a Gram-negative, microaerophilic bacterium characterized by its spirilla shape and presence of flagella. It typically exists in chains or as single cells and is classified as a chemoorganotroph, utilizing organic compounds for energy. The bacterium has a mesophilic temperature range, with an optimal growth temperature of 37°C, making it well-suited to thrive in host-associated environments. S. enterica subsp. enterica serovar Senftenberg is known to have a diverse range of hosts, including Homo sapiens (humans), Gallus gallus (chickens), and various other metazoans, plants such as Solanum lycopersicum (tomato) and Hordeum vulgare (barley), as well as mammals like Sus scrofa (pigs) and Columbidae (pigeons). This versatility in host affinity contributes to its significance in foodborne illnesses, where it can cause a variety of health effects including bacteremia, acute cholecystitis, diarrhea, gastroenteritis, and systemic infections. Notably, the bacterium does not form spores, which can influence its survival strategies in various ecological niches. Its free-living biotic relationship, coupled with the capacity to infect multiple hosts, highlights its role in the transmission of foodborne diseases. The presence of a single replicon and a double membrane structure further indicate its complexity as a pathogen. Understanding the characteristics of S. enterica subsp. enterica serovar Senftenberg is crucial for managing health risks associated with this bacterium in both human and animal populations.
