Brucella melitensis ATCC 23457

Brucella melitensis ATCC 23457 is a Gram-negative bacterium with a cocci shape, typically arranged in chains, pairs, or as singles. This organism is a facultative aerobe, allowing it to thrive in environments with varying oxygen levels. It is non-motile and does not possess flagella, which is consistent with its stationary lifestyle. B. melitensis is mesophilic, with an optimal growth temperature of 37°C, which aligns with the body temperature of its primary hosts. This bacterium is known to be pathogenic, particularly affecting livestock and potentially humans, leading to brucellosis, a significant zoonotic disease. The organism features a unique cellular structure with two membranes and a single replicon, characteristics that are typical of the Brucella genus. It is nonsporulating, indicating that it does not form spores as a survival mechanism. In terms of its ecological role, B. melitensis is primarily host-associated, indicating a close relationship with its animal hosts. Its free-living biotic relationship suggests that it may also exist in the environment, albeit in a limited capacity, outside of its host. Understanding the characteristics of Brucella melitensis ATCC 23457 enhances our knowledge of its pathogenic potential and ecological interactions, emphasizing the importance of monitoring this bacterium in both agricultural and public health contexts.
