Qhov sib txawv tseem ceeb ntawm E. coli thiab Pseudomonas aeruginosa yog E. coli yog cov kab mob facultative anaerobic kab mob uas belongs rau tsev neeg Enterobacteriaceae thiab genus Escherichia, thaum P. aeruginosa yog ib hom kab mob aerobic uas yog tsev neeg Pseudomonadadaceae thiab genus Pseudomonas.
Ob leeg E. coli thiab Pseudomonas aeruginosa yog cov kab mob gram-negative, rod-shaped thiab motile bacteria. Tsis tas li ntawd, lawv yog cov kab mob encapsulated. Tab sis, E. coli yog ib hom genus Escherichia thaum P. aeruginosa yog hom genus Pseudomonas.
E. Coli yog dab tsi?
E. coli yog ib tug gram-negative, qws-puab, facultative anaerobic kab mob uas belongs rau tsev neeg Enterobacteriaceae. Nws yog ib qho kab mob faecal coliform uas feem ntau pom nyob rau hauv cov hnyuv qis ntawm cov kab mob ntshav sov. Ntau hom kab mob E. coli tsis muaj teeb meem, thiab lawv yog ib feem ntawm cov microbiota ntawm lub plab uas ua rau lub plab noj qab nyob zoo. Txawm li cas los xij, qee qhov serotypes ua rau muaj mob hnyav, mob plab mob hnyav, raws plab ntshav, raum tsis ua haujlwm thiab ntuav. Tshwj xeeb tshaj yog cov kab mob E. coli O157:H7 tsim cov tshuaj lom neeg muaj zog hu ua Shiga, uas yog lub luag haujlwm rau kev ua rau muaj mob hnyav. E. coli nkag rau peb los ntawm txoj kev faecal-qhov ncauj. Dej, zaub nyoos, mis tsis muaj kua mis thiab nqaij tsis noj, yog ob peb qhov chaw ntawm E. coli. Yog li, nws muaj peev xwm txo tau cov kab mob E. coli feem ntau los ntawm kev npaj zaub mov kom raug thiab kev tu cev zoo.
Daim duab 01: E. coli
E.coli yog ib qho tseem ceeb ntawm cov qauv prokaryotic kab mob uas siv nyob rau hauv biotechnology thiab microbiology. Li no, hauv ntau qhov kev sim DNA recombinant, E. coli ua haujlwm ua tus tswv tsev. Cov laj thawj tom qab siv E. coli ua cov qauv kab mob tseem ceeb yog qee yam ntawm E. coli xws li kev loj hlob sai, muaj cov kab lis kev cai pheej yig kom loj hlob, yooj yim rau kev tswj hwm, kev paub dav ntawm nws cov noob caj noob ces thiab genomics, thiab lwm yam.
Pseudomonas Aeruginosa yog dab tsi?
Pseudomonas aeruginosa yog kab mob gram-negative zoo li tus kab mob uas muaj nyob hauv av, dej thiab lwm qhov chaw noo. Zoo ib yam li E. coli, P. aeruginosa yog cov kab mob encapsulated. Tsis tas li ntawd, nws yog cov kab mob motile. Nws muaj ib tug flagellum. Tsis tas li ntawd, P. aeruginosa yog ib feem ntawm daim tawv nqaij flora. Nws tsis yog kab mob phem. Txawm li cas los xij, nws ua raws li tus kab mob kis tau zoo. Thaum P. aeruginosa muaj kab mob, nws ua rau mob qog noj ntshav, cystic fibrosis, thiab kub hnyiab.
Daim duab 02: P. aeruginosa fluorescence nyob rau hauv UV illumination
Ib yam ntawm cov yam ntxwv ntawm P. aeruginosa yog cov fluorescence nws tsim nyob rau hauv UV teeb. Nws yog vim kev tsim cov fluorescent pigment pyoverdin los ntawm cov kab mob no.
Dab tsi zoo sib xws ntawm E. Coli thiab Pseudomonas Aeruginosa?
- Ob leeg E. coli thiab Pseudomonas aeruginosa yog ob yam kab mob uas yog gram-negative thiab rod-shaped.
- Lawv yog cov kab mob encapsulated.
- Ntxiv mus, lawv yog cov kab mob kis rau tib neeg.
- Ob tus kab mob no yog motile.
Qhov txawv ntawm E. Coli thiab Pseudomonas Aeruginosa yog dab tsi?
E.coli yog cov kab mob coliform uas muaj nyob hauv genus Escherichia. Ntawm qhov tod tes, P. aeruginosa yog cov kab mob uas tsis yog-coliform uas yog nyob rau genus Pseudomonas. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm E. coli thiab Pseudomonas aeruginosa.
Tsis tas li ntawd, E. coli yog ib feem ntawm cov plab hnyuv ib txwm muaj thaum P. aeruginosa yog ib feem ntawm cov tawv nqaij ib txwm muaj. Tsis tas li ntawd, qhov sib txawv ntxiv ntawm E. coli thiab Pseudomonas aeruginosa yog E. coli muaj peritrichous flagella thaum Pseudomonas aeruginosa muaj ib lub flagellum.
Summary – E. Coli vs Pseudomonas Aeruginosa
E.coli thiab P. aeruginosa yog ob hom kab mob uas muaj nyob hauv genus Escherichia thiab genus Pseudomonas, raws li. Ob leeg yog grams tsis zoo, pas nrig-puab, encapsulated motile kab mob. Ntxiv mus, E. coli yog facultative anaerobic, thaum P. aeruginosa feem ntau yog aerobic. Yog li, qhov no yog qhov tseem ceeb ntawm qhov sib txawv ntawm E. coli thiab Pseudomonas aeruginosa. Tsis tas li ntawd, E. coli muaj peritrichous flagella thaum P.aeruginosa muaj ib tug polar flagellum.
