Salmonella enterica subsp. enterica serovar Derby strain HIY0031

Salmonella enterica subsp. enterica serovar Derby strain HIY0031 is a Gram-negative bacterium, classified as a chemoorganotroph, which indicates its reliance on organic compounds for energy. This strain exhibits a microaerophilic oxygen requirement, thriving in environments with lower oxygen levels. Morphologically, it is characterized by a spirilla shape and typically appears in chains or as singles. HIY0031 possesses flagella, which are structures that facilitate motility; however, this strain is noted to be non-motile. It has a mesophilic optimal growth temperature of 37°C, which aligns with the typical body temperature of warm-blooded hosts, further indicating its host-associated habitat. The structure of its cell envelope consists of two membranes, a trait common to Gram-negative bacteria. In terms of genetic organization, HIY0031 has one replicon, suggesting a relatively simple genetic architecture. The strain's biotic relationship is classified as free-living, which may allow it to survive outside of host organisms under specific environmental conditions. Understanding the traits of Salmonella enterica serovar Derby strain HIY0031 provides insight into its ecological role. Its adaptation to a microaerophilic environment and mesophilic temperature range suggests an evolutionary relationship with warm-blooded hosts, where it may contribute to the dynamics of gut microbiota or cause infections. The presence of flagella, despite noted non-motility, could imply a potential for environmental persistence or interaction with host tissues, further emphasizing its ecological importance.
