. N. elongata is unusual among Neisseria species in being a rod-shaped organism in contrast to other Neisseria spp. which are diplococci. Also in contrast to most Neisseria spp., N. elongata is catalase-negative and superoxol-negative.. Images of colony morphology and results of biochemical tests have been included to aid the audience in recognizing and differentiating among. Neisseria meningitidis from various serogroups and two commensal neisseriae (N. sicca and N. perflava) were isolated from 15 patients at various stages of human immunodeficiency virus infection in this clinical and bacteriological study. The cases were grouped into the following three classes: (i) infections with an N. meningitidis strain of a serogroup known to be pathogenic (A, B, or C) and. Neisseria species are gram-negative cocci that are oxidase positive. All 3 species oxidase + N. meningitidis in blood. Gram stain: The Gram stain, is a laboratory staining technique that distinguishes between two groups of bacteria that have differences in the structure of their cell walls. Standard.
Neisseria bacteria are responsible for the diseases meningitis and gonorrhoeae. Gonorrhea, which is caused by Neisseria gonorrhoeae, is a sexually transmitted disease that is second only to chlamydia in reported cases to the CDC; 361,705 cases were reported in 2001.The bacteria begins infection through colonizing mucosal surfaces; humans are the only host of this bacteria and it is transmitted.

Most Neisseria species are gram-negative cocci or diplococci; currently, N. elongata is the only species of human origin with a bacillary morphology. Here, we report isolation and characterization of eight strains of another bacillary Neisseria species from human infections. The organisms caused or contributed to either oral cavity-related or respiratory tract infections, and two strains were. MORPHOLOGY OF NEISSERIA MENINGITIDIS (MENINGOCOCCUS).

Commensal non-pathogenic Neisseria spp. compete for mucosal niches alongside the pathogenic Neisseria meningitidis and Neisseria gonorrhoeae. Horizontal gene transfer, resulting from natural competence within the genus, has been seen to go from commensals to pathogens and reverse. Four distinct Neisseria spp. were isolated from the throats of two southwest London university students and have. Neisseria spp. possess four genogroups of filamentous prophages, termed Nf1 to 4. A filamentous bacteriophage from the Nf1 genogroup termed meningococcal disease-associated phage (MDA φ) is associated with clonal complexes of Neisseria meningitidis that cause invasive meningococcal disease Other Neisseria spp. are able to colonize a range of non-human mammalian and non-mammalian hosts, such as non-human primates, dogs, cats, herbivorous mammals, dolphins, birds and insects 13 Neisseria spp.• Characteristic diplococcus (bean shaped)• Inhabit mucous membranes of warmblooded hosts• Aerobic, non-motile, no spores, growoptimally at 37°C, growth stimulated byCO2 and NG has obligate requirement,oxidase positive, produce acid fromcarbohydrates oxidatively, most catalasepositive (cf Kingella -ox + but cat -) 4

Neisseria gonorrhoeae and Neisseria meningitidis cause gonorrhoea and meningitis, respectively. During infection, pathogenic Neisseria organisms are exposed to oxidative stress (reactive oxygen species and reactive nitrogen species) generated by host defense mechanisms. As a consequence, pathogenic Neisseria spp. have evolved numerous defense mechanisms to sense and cope with oxidative stress. The family Neisseriaceae is currently the only family within the order Neisseriales, which in addition to the genus Neisseria contains Eikenella, Kingella, and 27 other genera. Multiple-locus instead of single-locus approaches might therefore be more suitable for the resolution of species identification within the genus Neisseria. Neisseria species produce acid from carbohydrates by oxidation. The ideal laboratory test to detect Neisseria gonorrhoeae (Ng) should be sensitive, specific, easy to use, rapid, and affordable and should provide information about susceptibility to antimicrobial drugs. Currently, such a test is not available and presumably will not be in the near future. Thus, diagnosis of gonococcal infections presently includes application of different techniques to. NEISSERIA Of the eleven species of Neisseria that colonize humans, only two are pathogens. 1N. gonorrhoeae (the gonococcus) is the causative agent of gonorrhoea and is transmitted via sexual contact.

Ninety‐seven strains of presumptive Neisseria spp. obtained from the dental plaque of a wide variety of animals and 21 strains from culture collections were compared by physiological tests, enzyme electrophoresis and isoelectric focusing of proteins. Three physiological groups based on the fermentation of maltose and production of extracellular polysaccharide were established Of the ten human-restricted Neisseria species two, Neisseria meningitidis, and Neisseria gonorrhoeae, cause invasive disease: the other eight are carried asymptomatically in the pharynx, possibly.

The physical properties of most bacterial genomes are largely unexplored. We have previously demonstrated that the strict human pathogen Neisseria gonorrhoeae is polyploid, carrying an average of three chromosome copies per cell and only maintaining one pair of replication forks per chromosome (D.
