Salmonella enterica subsp. houtenae serovar 50:g

Salmonella enterica subsp. houtenae serovar 50:g is a Gram-negative microbe characterized by its spirilla shape and its tendency to form chains and singles. This bacterium thrives optimally at a temperature of 37.0°C, which aligns with the typical body temperature of warm-blooded hosts, indicating its adaptation to a host-associated habitat. As a chemoorganotroph, S. enterica subsp. houtenae serovar 50:g utilizes organic compounds as its energy source, further supporting its association with hosts that provide a nutrient-rich environment. This microbe exhibits microaerophilic growth, suggesting that it requires reduced oxygen levels for optimal metabolism, a trait that may influence its ecological niche within the host. The microaerophilic nature points to potential interactions with the host's immune responses and the microbiota, which may regulate the local oxygen levels in the host's environment. This unique adaptation may facilitate its survival and proliferation within specific niches in the host, highlighting the intricate balance between microbial inhabitants and their hosts in maintaining health and homeostasis.
