Gram Positive vs. Gram Negative Bacteria Vetenskap

2021-03-22 · Moraxella catarrhalis is a gram-negative, aerobic, oxidase-positive diplococcus that was first described in 1896. The organism has also been known as Micrococcus catarrhalis, Neisseria catarrhalis, and Branhamella catarrhalis; currently, it is considered to belong to the subgenus Branhamella of the genus Moraxella. Studies have shown that M catarrhalis colonizes the upper respiratory tract in 28-100% of humans in the first year of life. In adults, the colonization rate is 1-10.4%.
