Download as PDF. Moraxella catarrhalis is a Gram-negative diplococcus, which means it’s a spherical-shaped bacteria that usually hangs out in pairs of two. Moraxella has had a bunch of names over the last century. When it was first discovered it was named Micrococcus catarrhalis, … The identity ofan isolate as M catarrhalis was confirmed by colony morphology and PCR. The second BAL specimen was centrifuged at 1,200 rpm for 15 min. The pellet was resuspended in 50 ml ofPBS, layered on to Ficoll-Hypaque gradient in two 50 ml polypropylene tubes and run at 2,200 rpm for 25 minutes. At the end of Another genus with which they can be confused, especially the species M. catarrhalis, it's with Neisseria, both for its morphology and for the oxidase test.. In this case they are differentiated by the incapacity of the gender Moraxella to form acid from carbohydrates, while most of the Neisseria if they are able to ferment some carbohydrates..
