(Summary description)Moraxella catarrhalis (MC) was first discovered in 1896. At that time, it was called Micrococcus catarrhalis. Later, it was also called Neisseria catarrhalis and Branhamella catarhalis. Gram negative bacteria are shown by Gram staining. In the past, Moraxella catarrhalis was considered to be a normal parasite of the upper respiratory tract without pathogenicity to human body. However, studies over the past 20 years have found that the bacterium can not only cause upper respiratory tract infection in children and the elderly, but also an important pathogen causing lower respiratory tract infection in adults. It is the third most common pathogen of maxillary sinusitis, otitis media, pneumonia in children and chronic lower respiratory tract infection in adults, second only to Haemophilus influenzae and Streptococcus pneumoniae, Moreover, the incidence rate is increasing year by year, especially in patients with chronic obstructive pulmonary disease. Therefore, rapid identification of MC has important clinical significance. We identified MC by indole acetate disk method.
