Neisseria

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 Neisseria menigitidis. Etter pneumokokker er meningokokker vanligste mikrobe ved meningitt i Norge. Dødeligheten er 3 - 13%. Dersom pasienten har petekkier, er meningokokker sannsynlig, ved meningokokksykdom er petekkier vanlig 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. Neisseria: [ ni-se´re-ah ] a genus of gram-negative, aerobic or facultatively anaerobic cocci, which are a part of the normal flora of the oropharynx, nasopharynx, and genitourinary tract. Pathogenic species include N. gonorrhoe´ae, the etiologic agent of gonorrhea ; N. meningi´tidis, a prominent cause of meningitis and the specific agent of. Neisseria meningitidis, often referred to as meningococcus, is a Gram-negative bacterium that can cause meningitis and other forms of meningococcal disease such as meningococcemia, a life-threatening sepsis.The bacterium is referred to as a coccus because it is round, and more specifically, diplococcus because of its tendency to form pairs. . About 10% of adults are carriers of the bacteria in.

Gonoré er en kjønnssykdom forårsaket av bakterien Neisseria gonorrhoeae. Navnet henspiller på at sykdommen ofte fører til utflod fra penis. Utfloden er puss som skyldes betennelsen i urinrøret. Gonoré kan smitte til urinrør, skjede, anus og hals. Vanligste symptomer er svie ved vannlatning og utflod fra urinrør eller skjede. Ubehandlet kan infeksjonen føre til bekkeninfeksjon og økt. Neisseria gonorrhoeae er en gram-negativ kuleformet (kokker) bakterie som forårsaker sykdommen gonoré..

Indikasjon Dyrkning for gonore anbefales i tillegg til DNA påvisning ved symptomer (dysuri, utflod, bekkensmerter, epididymitt) og ved smittesporing. Dyrkningsprøve anbefales før antibiotikabehandling av hensyn til epidemiologisk overvåkning og resistensbestemmelse. Dyrkning skal alltid utføres etter positiv Neisseria gonorrhoeae DNA analyse dersom ikke utført primært. Andre. Neisseria menigitidis is a Gram-negative, aerobic, nonmotile, nonspore-forming, oxidase-positive, catalase-positive coccus. Most disease-causing strains of N. meningitidis belong to serogroups A, B, or C: serogroup A strains are often responsible for epidemic disease in developing countries, whereas serogroup B and C strains are more often associated with disease outbreaks in developed countries Neisseria gonorrhoeae multi-antigen sekvenstype (NG-MAST) og multilokus sekvens typing (MLST) brukes for å påvise klon-tilhørighet.

Description and Significance. Neisseria meningitidis is a parasitic, aerobic, Gram-negative, non endospore forming, nonmotile (although piliated) , coccal bacterium that is responsible for causing meningitis, inflammation of the meninges layer covering the brain. Because it is an aerobic organism, like most members of the Neisseriaceae family, it also has catalase and oxidase activity Introduction. The primary purpose of this page is to provide illustrations of characteristics of N. meningitidis that may aid in differentiating between this, and other, Neisseria species that produce acid from glucose and maltose.. This page is not intended to be a definitive discussion of N. meningitidis infections but to provide information relating to the accurate identification of N. Neisseria gonorrhoeae. Undersøkelsesmetode: Direkte påvisning av bakterier med PCR teknikk.

Neisseria gonorrhoeae is a gram-negative coccus, or bacteria whose overall shape is spherical. It is usually seen in pairs with adjacent sides flattened. The organism is usually found interacellulary in polymorphonuclear leukocytes, or a specific category of white blood cells with varying shapes of nuclei, of the gonorrhea pustular exudates [8] with humans as its.
