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.

In humans, it has been isolated from the upper respiratory tract of neutropenic patients. However, only two cases of N. macacae bacteremia have been reported in a 65-year-old man with infective endocarditis and a 5-month-old child with fever and petechiae.

Neisseria spp. are facultatively intracellular and typically appear in pairs (diplococci), resembling the shape of coffee beans. Nesseria is non-spore-forming, capable of moving using twitching motility, and an obligate aerobe (requires oxygen to grow). Of the 11 species of Neisseria that colonize humans, only two are pathogens 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. Like other Neisseria spp., N. flava is an aerobic β-proteobacteria . The organism inhabits the upper respiratory tract of human  . There is no extensive study of N. flava and its host range, however, the organism has been identified in the oropharyngeal of rhesus macaques, which suggests that this species is not host restrict to only human  Chapter 40 Neisseria and Moraxella catarrhalis Objectives 1.

Neisseria spp. produce acid from carbohydrates by oxidation, not fermentation. Chemoorganotrophic. Exotoxins are not produced. Some species are saccharolytic. Inhabitants of the mucous membranes of mammals. Some species are primary pathogens of humans. The genus Neisseria belongs to the family Neisseriaceae of the Betaproteobacteria Neisseria spp. produce enzymes which hydrolyze various chromogenic substrates. When these substrates are bound to another base, the hydrolysis will produce a color reaction, some apparent immediately and others by the addition of color developers. Neisseria test tablets,.

Neisseria 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.Most gonococcal infections are asymptomatic and self-resolving, and epidemic strains of the meningococcus may be carried in >95% of a population where systemic disease occurs at . 1% prevalence NON PATHOGENIC NEISSERIA.

MORPHOLOGY OF NEISSERIA MENINGITIDIS (MENINGOCOCCUS). Shape - Neisseria meningitidis is an oval or spherical (coccus) shape bacterium with the adjacent side flattened.. Size - The size of Neisseria meningitidis is about 0.6 µm - 0.8 µm (micrometer).. Arrangement Of Cells - Neisseria meningitidis is arranged in pairs (diplococci), with the adjacent side flattened and they are usually. Neisseria spp. can only grow on this agar, because the organism needs nutrients inside blood cells, but doesn't have any hemolysins. Therefore, the chocolate agar provides those nutrients. The Thayer-Martin agar, or the VPN agar, are specialized agars that have antibiotics to specifically grow only Neisseria spp

Incubation 2 to 5 days ; Attaches to urethral or vaginal columnar epithelial cells by pili and other surface protein Translation for 'neisseria spp' in the free English-Chinese dictionary and many other Chinese translations 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.

By N Morla, M Guibourdenche and J Y Riou. Abstract. 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 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.

Neisseria spp.. Phylum: Proteobacteria Class: Betaproteobacteria Order: Neisseriales Family: Neisseriaceae Genus: Neisseria The genus Neisseria belongs to the family Neisseriaceae. This genus, Neisseria, is divided into more than ten different species, but most of them are gram negative and coccoid. The gram-negative, coccoid species include: Neisseria cinerea, Neisseria gonorrhoeae, Neisseria. Neisseria sicca/subflava are sacharolytic species of the family Neisseriaceae that are commensal inhabitants of the human oropharynx. 1 These organisms have been occasionally reported as the cause of significant human infections in normal and immunocompromised patients. In this report, we describe an immunosuppressed pediatric patient who developed N. sicca/subflava bacteremia manifested by.
