Moraxella catarrhalis
Moraxella catarrhalis
Moraxella catarrhalis (pronunciation: mo-rax-ella cat-ha-ralis) is a Gram-negative, aerobic, oxidase-positive diplococcus bacterium. It is a human pathogen that plays a role in many infections, including those of the respiratory tract and middle ear.
Etymology
The name Moraxella catarrhalis derives from Victor Morax, a Swiss ophthalmologist who first described this genus of bacteria. The species name catarrhalis is a Latin word meaning "pertaining to catarrh," a condition often involving the inflammation of a mucous membrane.
Infections
Moraxella catarrhalis is associated with a number of infections, most notably otitis media (middle ear infection) and bronchitis. It is also a common cause of sinusitis and can lead to pneumonia in individuals with weakened immune systems.
Treatment
Treatment for Moraxella catarrhalis typically involves antibiotics, such as amoxicillin or doxycycline. However, some strains of the bacteria have developed resistance to certain antibiotics, making treatment more challenging.
