Moraxella catarrhalis formerly known as Micrococcus catarrhalis, Neisseria catarrhalis and later Branhamella catarrhalis was first isolated in 1896 and was thought to be a harmless normal flora of human upper respiratory tract for the subsequent 50 years. However only in the past decade or so its role as a disease causing

In the last 20 years however, there have been an increasing number of reports of M. catarrhalis isolations from a variety of settings, as well as the emergence of penicillin-, ampicillin- and amoxicillin-resistant strains, together with an increase in virulence, which have forced Chapter 40 Neisseria and Moraxella catarrhalis Objectives 1. Identify the clinical specimens or sources for the isolation of pathogenic Neisseria spp. 2. List the Neisseria species considered normal flora and the sites where they colonize the human body. 2021-03-22 · For definitive identification, deoxyribonuclease (DNase) and nitrate reduction tests are performed; M catarrhalis produces DNase and reduces nitrate and nitrite levels. Several rapid confirmatory tests are available to identify M catarrhalis, and they are all based on the ability of M catarrhalis to hydrolyze tributyrin.

Old synonyms: Mikrokkokus catarrhalis (sic) Frosch and Kolle in Flügge 1896, Neisseria catarrhalis (Frosch and Kolle 1896) Holland 1920. 2015-02-08 As far as Branhamella catarrhalis is concerned, identification by standard biochemical methods is time consuming while use of the rapid tests can be inaccurate.

The M. catarrhalis colonies scored positively on this test, which means they could be slid across the plate. SUMMARY Moraxella catarrhalis (formerly known as Branhamella catarrhalis) has emerged as a significant bacterial pathogen of humans over the past two decades. During this period, microbiological and molecular diagnostic techniques have been developed and improved for M. catarrhalis, allowing the adequate determination and taxonomic positioning of this pathogen.

2011-01-27 · These test results presented a conundrum as to the actual identity of both the mucoid and dry colony types of isolates. Insofar as the mucoid isolates were concerned, the biochemical test results were consistent with Moraxella (Branhamella) catarrhalis.

Eikenella corrodens, Kingella spp., and Cardiobacterium hominis, produced unique biochemical reaction patterns on the panel. Modification of interpretative criteria for certain tests, expansion of the data base to includeotherspecies, andsuggestionsfor additional confirmatory tests will increasetheaccuracy andutility of the HNIDpanel.
