Brucella abortus str. BAU21/S4023

Brucella abortus str. BAU21/S4023 is a Gram-negative, rod-shaped bacterium that typically exists as single cells and exhibits facultative aerobic metabolism. This strain does not form spores and is optimally adapted to a temperature of 37.0°C, which coincides with the physiological temperature of many mammalian hosts. The bacterium's habitat is diverse, suggesting that it may thrive in various environments, potentially including those associated with livestock and wildlife. The nonsporulating nature of Brucella abortus indicates a reliance on stable environmental conditions for survival and growth, which may be linked to its ecological niches. As a facultative aerobe, B. abortus str. BAU21/S4023 is capable of utilizing both aerobic and anaerobic metabolic pathways, allowing it to adapt to fluctuating oxygen levels in its surroundings. This metabolic flexibility may enhance its survival in different habitats, where it can exploit various organic substrates. Given its optimal growth temperature and diverse habitats, B. abortus str. BAU21/S4023 may play a role in the microbiomes of its environments, influencing nutrient cycling and interactions with other microorganisms. This adaptability underscores the ecological significance of Brucella species in their natural habitats, where they may contribute to the dynamic balance of microbial communities.
