Salmonella enterica subsp. enterica serovar Newport strain SE89

Salmonella enterica subsp. enterica serovar Newport strain SE89 is a Gram-negative, microaerophilic bacterium characterized by its spirilla shape and arrangement in chains or singles. This strain is classified as a chemoorganotroph, indicating that it derives energy from organic compounds. It possesses flagella, which are critical for its motility, although the strain is noted to be non-motile. Typically associated with a host habitat, strain SE89 has been identified in various hosts, including Homo sapiens (humans), Bos (cattle), Phasianidae (pheasants), and Procyon lotor (raccoons). The strain's optimal growth temperature is around 37°C, placing it within the mesophilic range. It has a single replicon and is characterized by a double membrane structure. The biotic relationship of Salmonella enterica serovar Newport strain SE89 is classified as free-living, suggesting its ability to exist independently of a host, although it is also capable of infecting specific hosts. This duality highlights the ecological significance of the strain, as it can adapt to both environmental and host-associated lifestyles. Understanding these traits is crucial for developing strategies to mitigate the risks associated with this pathogen, particularly in relation to food safety and public health.
