Salmonella enterica subsp. arizonae strain NCTC7304

Salmonella enterica subsp. arizonae strain NCTC7304 is a Gram-negative bacterium characterized by its spirilla shape and microaerophilic oxygen requirement. This strain is a chemoorganotroph, indicating that it derives its energy from organic compounds. It is notable for its cell arrangement, typically found in chains or as single cells, and it possesses flagella, which are structures used for movement, although this strain is immobile. The optimal growth temperature for Salmonella enterica subsp. arizonae strain NCTC7304 is 37°C, placing it within the mesophilic temperature range. The bacterium has a single replicon and is surrounded by two membranes, which is a characteristic feature of Gram-negative bacteria. This strain is host-associated, primarily found in amphibian hosts, specifically the genus Gastrotheca. The biotic relationship is categorized as free-living, suggesting it can exist independently of its host but is commonly associated with it. Understanding the ecological niche of Salmonella enterica subsp. arizonae strain NCTC7304 is important for assessing its role in amphibian health and potential implications for public health, especially given the significance of amphibians in ecosystems. This relationship highlights the interconnectedness of microbial life and its hosts, emphasizing the importance of monitoring such bacteria in environmental and clinical contexts.
