Salmonella enterica subsp. enterica serovar Infantis str. SARB27 str. SARB 27

Salmonella enterica subsp. enterica serovar Infantis str. SARB27 (SARB 27) is a Gram-negative bacterium characterized by its spirilla shape and ability to form chains or exist as single cells. This strain thrives optimally at 37.0°C, making it well-suited for survival in host-associated environments, such as the gastrointestinal tracts of various animals. As a chemoorganotroph, SARB 27 utilizes organic compounds as its primary energy source, indicating its metabolic versatility in nutrient-rich habitats. SARB 27 exhibits a microaerophilic oxygen requirement, suggesting that it prefers environments with lower levels of oxygen compared to atmospheric conditions. This trait may reflect its adaptation to the intestinal microbiome, where oxygen concentrations are often limited. The ability to form chains could be advantageous for colonization and persistence within host environments, potentially facilitating interactions with other microbial species and contributing to niche establishment. Overall, the combination of its Gram-negative cell wall structure, optimal growth temperature, and microaerophilic lifestyle underscores SARB 27's adaptation to host-associated habitats. Further studies could elucidate the ecological roles of this strain within the microbiota of its hosts, particularly in how it interacts with both host and other microbial communities in the gastrointestinal environment.
