Qhov sib txawv tseem ceeb ntawm Neisseria thiab Moraxella yog Neisseria yog ib lub genus uas nyob rau hauv chav kawm ntawm beta proteobacteria thaum Moraxella yog ib tug genus uas belongs rau chav kawm ntawm gamma proteobacteria.
Proteobacteria yog ib lub cev loj uas muaj cov kab mob gram-negative. Cov kab mob no muaj ntau yam kab mob xws li Escherichia, Salmonella, Vibrio, Helicobacter, Neisseria, Yersinia, Legionella, thiab lwm yam hauv cov kab mob no yog cov kab mob dawb nyob tsis muaj kab mob. Ntau tus kab mob hauv lub cev no tuaj yeem kho cov huab cua N 2 Carl Woese tau tsim pab pawg no hauv xyoo 1987. Muaj cuaj chav kawm ntawm proteobacteria raws li ribosomal RNA (rRNA) ib ntus: alpha, beta, gamma, delta, epsilon, zeta, thiab lwm yam
Neisseria yog dab tsi?
Neisseria yog ib tug loj genus uas belongs rau beta proteobacteria. Feem ntau, Neisseria colonizes nyob rau hauv mucosal nto ntawm ntau yam tsiaj. Tawm ntawm 11 hom uas nyob hauv tib neeg, tsuas yog ob hom kab mob pathogenic: N. meningitidis thiab N. gonorrhoeae. Txawm li cas los xij, feem ntau cov kab mob gonococcal yog asymptomatic thiab daws tus kheej. Neisseria hom yog cov kab mob gram-tsis zoo. Lawv kuj yog diplococci uas zoo li cov noob taum kas fes thaum saib hauv qab lub tshuab tsom. Ntxiv mus, Neisseria hom yog catalase thiab oxidative zoo nyob rau hauv biochemical kuaj.
Daim duab 01: Neisseria
Neisseria hom ib txwm loj hlob hauv khub tab sis qee zaus tuaj yeem ua tetrads. Lawv vam meej zoo tshaj plaws ntawm 98.6 0 F hauv tsiaj lub cev lossis kab lis kev cai. N. meningitidis ua rau meningitidis thiab septicaemia, thaum N. gonorrhoeae ua rau gonorrhoea. Ob hom no muaj peev xwm ua txhaum txoj cai tseem ceeb hauv tib neeg lub cev. Tsis tas li ntawd, cov tsiaj no zam feem ntau ntawm cov txheej txheem tiv thaiv, xws li neutrophils, phagocytosis, thiab cov kab ke ntxiv. Neisseria hom tseem qhia txog kev hloov pauv ntawm cov tshuaj tiv thaiv kab mob los ntawm kev hloov lawv cov antigens. Tsis tas li ntawd, lawv muaj hom IV pili uas muaj ntau yam haujlwm xws li kev sib txuas, twitching motility, microcolony tsim, antigenic variation, thiab lwm yam. Cov genus no kuj muaj qee hom commensal lossis non-pathogenic hom: N. bacilliformis, N. cinerea, N. elongata., N. flavescens, etc.
Moraxella yog dab tsi?
Moraxella yog ib lub genus uas nyob rau hauv chav kawm ntawm gammaproteobacteria. Lawv yog cov kab mob gram-negative. Lawv belongs rau tsev neeg ntawm Moraxellaceae. Cov kab mob no muaj npe tom qab Swiss ophthalmologist Victor Morax. Moraxella hom tuaj yeem yog luv luv, coccobacilli lossis diplococci. Cov hom no feem ntau yog asaccharolytic, oxidase-positive thiab catalase-positive. M. catarrhalis yog hom kab mob tseem ceeb tshaj plaws nyob rau hauv cov genus no. Moraxella yog ib qho kev pom zoo ntawm qhov chaw mucosal. Tab sis qee zaum, cov tsiaj no ua rau muaj kev kis kab mob kis tau zoo.
Daim duab 02: Moraxella
M. catarrhalis feem ntau nyob rau hauv lub Upper pa ib ntsuj av. Tab sis nws tuaj yeem nkag mus rau hauv cov hlab ntsws qis hauv cov neeg mob uas muaj kab mob hauv siab. Yog li, qhov no ua rau mob ntsws. Ntxiv mus, M. lacunata ua rau blepharoconjunctivitis hauv tib neeg thiab M.bovis ua rau kis kab mob bovine keratoconjunctivitis hauv nyuj.
Dab tsi yog qhov zoo sib xws ntawm Neisseria thiab Moraxella?
- Neisseria thiab Moraxella yog ob hom ntawm proteobacteria.
- Ob leeg yog gram negative.
- Lawv yog diplococci.
- Ob leeg yog nruj aerobes.
- Lawv yog catalase zoo thiab oxidative zoo.
- Ob lub noob muaj kab mob thiab tsis muaj kab mob.
Qhov txawv ntawm Neisseria thiab Moraxella yog dab tsi?
Neisseria yog ib lub genus uas nyob rau hauv chav kawm ntawm beta proteobacteria thaum, Moraxella yog ib tug genus uas belongs rau chav kawm ntawm gamma proteobacteria. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm neisseria thiab moraxella. Tsis tas li ntawd, Neisseria yog monophyletic genus, thaum Moraxella yog ib hom kab mob paraphyletic.
Cov hauv qab no infographic teev qhov sib txawv ntawm neisseria thiab moraxella hauv daim ntawv tabular rau ib sab ntawm kev sib piv.
Summary – Neisseria vs Moraxella
Proteobacteria yog ib lub cev loj ntawm cov kab mob gram tsis zoo. Neisseria thiab Moraxella yog ob hom ntawm proteobacteria. Neisseria yog ib tug genus uas belongs rau chav kawm ntawm beta proteobacteria. Moraxella yog ib tug genus uas belongs rau chav kawm ntawm gamma proteobacteria. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm neisseria thiab moraxella.
