Species

Neisseria cinerea

Description and Significance

Neisseria cinerea is a gram-negative, mesophillic, diplococcus, about 1-2 mm long. N.cinerea was discovered in 1906 by a German scientist named Alexander von Lingelsheim in 1906, he misclassified it as Branhamella catarrhalis. N. cinerea resembles Neisseria gonorrhoeae in the way it cultures and its biochemical characteristics, the main difference between the two is N. cinerea appears golden brown, rather than the common pinkish of gram-negative bacteria when on chocolate agar.

Genome Structure

contains 1 circle chromosome with about 2 million base pairs from the various complete strains sequenced most had 1.8 million to 1.9 million BPs. strain NCTC10294 had nucleotides: 1832904, protein genes: 1710, RNA genes: 73. StrainNCTC10294 tRNA 59, rRNA 12, CDS1913 the strain NCTC10294 also contained about 40 antibiotic resistance genes, some from meningitis, streptococcus, and other deadly microbes, but this bacteria isn't pathogenic. Also, 84 Virulence Factor genes, which from what im understand from the charts it's the genes in the plasmids that have been shared by other bacteria, and the genes can be traced back to the exact bacterium it was from most of which are pathogenic.

Cell Structure, Metabolism and Life Cycle

builds acid from D-fructose, maltose, and sucrose, uses tryptophan as an energy source, degradation on ornithine, hydrolysis to urea

an asaccharolytic, gram-negative, oxidase-positive, lycine, serine, and threonine metabolism, Cysteine and methionine metabolism, Methane metabolism, Vitamin B6 metabolism, Metabolic pathways, Biosynthesis of secondary metabolites, Microbial metabolism in diverse environments, Carbon metabolism, Biosynthesis of amino acids, Biosynthesis of cofactors

Ecology and Pathogenesis

Habitat; symbiosis; biogeochemical significance; contributions to environment.

If relevant, how does this organism cause disease? Human, animal, plant hosts? Virulence factors, as well as patient symptoms.
