Moraxella catarrhalis strain COPD_M82

Moraxella catarrhalis strain COPD_M82 is a Gram-negative bacterium that exhibits notable characteristics relevant to its ecological and clinical significance. This strain is classified as an aerobe, requiring oxygen for growth, and presents a cocci shape. It is non-motile, lacking flagella, and possesses a mesophilic temperature range, indicating an optimal growth temperature that is typical of warm-blooded hosts. The bacterium is associated with various hosts, including Homo sapiens (humans), Macaca mulatta (rhesus monkeys), and Chinchilla, indicating its adaptability and potential for zoonotic transmission. It is categorized as free-living, which suggests that it can survive independently in its host-associated environments. Moraxella catarrhalis strain COPD_M82 is implicated in several respiratory health issues, including respiratory infections, otitis media, sinusitis, and exacerbations of chronic obstructive pulmonary disease (COPD). Its association with childhood otitis media and middle ear infections underscores its impact on pediatric health. The strain's ability to contribute to COPD-related infections in humans highlights its significance in chronic respiratory conditions, particularly in vulnerable populations. With a single replicon and a double membrane structure, M. catarrhalis exhibits typical characteristics of Gram-negative bacteria, which may influence its pathogenicity and interaction with the host’s immune system. The presence of this bacterium in various hosts and its involvement in significant health conditions emphasize its ecological role in respiratory health and disease dynamics.
