Salmonella enterica subsp. enterica serovar Typhimurium str. ST4/74

Salmonella enterica subsp. enterica serovar Typhimurium str. ST4/74 is a Gram-negative bacterium characterized by its spirilla shape and capability to exist in both single and chain arrangements. This strain thrives optimally at 37.0°C and exhibits microaerophilic growth, indicating its preference for environments with reduced oxygen levels. As a chemoorganotroph, it derives its energy from organic compounds, which aligns with its host-associated habitat, typically found within the gastrointestinal tracts of various hosts. The microaerophilic nature of S. Typhimurium ST4/74 suggests an adaptation to specific ecological niches where oxygen is limited, which may be critical for its survival and proliferation in host environments. This adaptation may also influence its interactions with the host microbiota, potentially affecting the overall microbial community structure. Understanding these traits can provide insights into the ecological roles of S. Typhimurium and its adaptations to host-associated habitats, highlighting the complexity of host-microbe interactions.
