Salmonella enterica subsp. enterica

Salmonella enterica subsp. enterica is a Gram-negative bacterium characterized by its spirilla shape and the ability to arrange in chains or as singles. This microbe is classified as a chemoorganotroph, indicating that it derives its energy from organic compounds. The optimal growth temperature for S. enterica subsp. enterica is approximately 37.0°C, which aligns with the typical body temperature of warm-blooded hosts, suggesting a close association with host environments. This bacterium exhibits a microaerophilic oxygen requirement, thriving in conditions with reduced oxygen levels, which is often found in certain host tissues or gastrointestinal tracts. The habitat of S. enterica subsp. enterica is predominantly host-associated, indicating its prevalence in living organisms, particularly in those of the animal kingdom. This relationship highlights its potential role in microbial communities within host organisms, where it may interact with other microbial species and influence host health. Understanding the ecological dynamics of S. enterica subsp. enterica within its host can provide valuable insights into its role in microbial interactions and its adaptation strategies in microenvironments characterized by fluctuating nutrient availability and oxygen levels.
