What phylum is Neisseria?
What phylum is Neisseria?
PseudomonadotaNeisseria / PhylumPseudomonadota is a major phylum of Gram-negative bacteria. The renaming of phyla in 2021 remains controversial among microbiologists, many of whom continue to use the earlier names of long standing in the literature. Wikipedia
What is the genus and species of Neisseria gonorrhoeae?
NeisseriaNeisseria gonorrhoeae / GenusNeisseria is a large genus of bacteria that colonize the mucosal surfaces of many animals. Of the 11 species that colonize humans, only two are pathogens, N. meningitidis and N. gonorrhoeae. Wikipedia
How many species of Neisseria are there?
17 species
The genus Neisseria is composed of 17 species that may be isolated from humans and six species that colonize various animals (Table 179-1). N. lactamica and N. cinerea are most closely related to the pathogenic Neisseria, and frequently colonize the nasopharynx of children and adults.
What is Neisseria in microbiology?
Neisseria spp. are a Gram-negative non-spore-forming diplococcus that has a flattened shape; its size ranges between 0.6–0.8 μm. They are oxidase-positive, non-acid-fast cocci or plump rods. They can reach a diameter of around 0.6–0.8 μm and sometimes up to 1.0 × 2.0–3.0 μm.
What are the characteristics of genus Neisseria?
NEISSERIA: GENERAL FEATURES They are nonmotile, non–spore-forming, and non–acid-fast. Their cell walls are typical of gram-negative bacteria, with a peptidoglycan layer and an outer membrane containing polysaccharides complexed with lipid and protein.

What is the genus of gonorrhea?
The genus Neisseria contains a number of species which are normal flora and pathogens of humans and animals. Of these species, the species of human origin–and particularly the pathogenic species, N. gonorrhoeae and N. meningitidis–have been studied extensively in an effort to control the infections they cause.
How do you identify Neisseria?
N. meningitidis can be identified using Kovac’s oxidase test and carbohydrate utilization. If the oxidase test is positive, carbohydrate utilization testing should be performed. If the carbohydrate utilization test indicates that the isolate may be N.
What are general characteristics of Neisseria?
What is the morphology of Neisseria?
Morphology: “Kidney bean” or “coffee bean” shaped cocci. Occurring singly, but more often in pairs with adjacent sides flattened. One species ( Neisseria elongata ) is an exception and consists of short rods 0.5 micrometers in width and is often arranged as diplobacilli or in short chains.
What is the morphology of Neisseria gonorrhoeae?
Morphology of Neisseria gonorrhoeae: Under the microscope, it appears as a gram-negative coccus which is present in pairs (diplococci) with the flattening of the adjacent sides. The diameter ranges from 0.6-1 μm. The diplococci have kidney/coffee bean shape.
