PY - 2018 T2 - Rudolph's Pediatrics, 23e AB - Moraxella catarrhalis is a gram-negative aerobic diplococcus that belongs to the Neisseriaceae family. In the past, it has been known as Micrococcus catarrhalis, Neisseria catarrhalis, and Branhamella catarrhalis. It commonly inhabits the upper respiratory tract. For many years, it was considered a nonpathogenic member of the resident flora of the nasopharynx. Over the past 30 to 35 years, it has been recognized as a genuine mucosal pathogen and is now considered an important cause of otitis media and sinusitis in healthy children and adults. It also causes lower respiratory tract infections and exacerbation of bronchitis in adults with chronic lung disease. Occasionally, it can cause a variety of severe infections, including septicemia, pneumonia, and meningitis, especially in immunocompromised hosts.
