Salmonella enterica subsp. enterica serovar Derby

Salmonella enterica subsp. enterica serovar Derby is a Gram-negative bacterium characterized by its spirilla shape and a tendency to form chains or exist as single cells. This microbe thrives optimally at a temperature of 37.0°C, which corresponds to the body temperature of many warm-blooded hosts, highlighting its adaptation to host-associated environments. As a chemoorganotroph, S. enterica serovar Derby utilizes organic compounds as its energy source, further emphasizing its association with host organisms where such nutrients are readily available. The microaerophilic nature of this bacterium indicates that it requires reduced levels of oxygen for growth, which is consistent with its habitat within the intestinal tracts of various hosts. This adaptation allows S. enterica serovar Derby to survive in environments where oxygen levels fluctuate, such as the gut, where it encounters both aerobic and anaerobic conditions. Understanding the ecological role of S. enterica serovar Derby within its host can provide insights into its interactions with the host microbiome and potential contributions to nutrient cycling. Its specific adaptation to microaerophilic environments may also influence its competition with other gut microbes, potentially shaping the microbial community structure in host-associated habitats.
