Qhov sib txawv tseem ceeb ntawm Pseudomonas aeruginosa thiab Pseudomonas fluorescens yog tias P. aeruginosa yog ib qho kev siv rau tib neeg cov kab mob thaum P. fluorescens tsis yog tib neeg cov kab mob. Qhia meej ntxiv, P. aeruginosa yog kab mob ntawm cov nroj tsuag thiab tsiaj txhu, suav nrog tib neeg, P. fluorescence yog cov nroj tsuag loj hlob txhawb cov kab mob. Lwm qhov sib txawv tseem ceeb ntawm Pseudomonas aeruginosa thiab Pseudomonas fluorescens yog tias P. aeruginosa muaj peev xwm loj hlob txawm tias ntawm 42 ° C.
Pseudomonas yog cov kab mob genus uas muaj cov kab mob gram-negative, rod-shaped thiab polar flagellated bacteria. Lawv yog cov kab mob aerobic uas tsis yog-spores tsim, catalase zoo thiab oxidase zoo. Tsis tas li ntawd, cov genus no muaj ntau hom xws li P. aeruginosa, P. fluorescens, P. putida, P. syringae, thiab lwm yam.
Pseudomonas Aeruginosa yog dab tsi ?
P. aeruginosa yog ib hom kab mob ntawm genus Pseudomonas. Nws yog ib tug kab mob gram-negative rod-zoo li tus kab mob uas muaj ib tug polar flagellum. Cov kab mob no muaj nyob hauv av, dej, tawv nqaij, thiab feem ntau ntawm tib neeg tsim ib puag ncig. Raws li kev lees paub, P. aeruginosa yog kab mob ua rau cov nroj tsuag thiab tsiaj txhu. Tsis tas li ntawd, nws ua hauj lwm raws li ib tug opportunistic human pathogen uas muaj cov cuab yeej ntawm multidrug kuj. Txij li thaum P. aeruginosa muaj peev xwm tiv thaiv kab mob; Nws yog lub luag haujlwm rau cov mob hnyav ntawm cov kab mob kis tau hauv tsev kho mob xws li lub tshuab ua pa uas cuam tshuam nrog mob ntsws thiab ntau yam kab mob sepsis.
Daim duab 01: P. aeruginosa
Nws nyuaj rau kho cov kab mob los ntawm P. aeruginosa vim tias cov kab mob no tiv taus cov tshuaj tua kab mob feem ntau. Txawm li cas los xij, piv rau lwm hom kab mob pathogenic, P. aeruginosa tsis yog ib qho kab mob uas tsis tshua muaj tshwm sim. Nws kuj muaj peev xwm tsim cov biofilms raws li nws muaj peev xwm ntawm colonizing feem ntau ntawm qhov chaw.
YPseudomonas Fluorescens yog dab tsi?
P. flourescens yog lwm hom kab mob ntawm cov genus Pseudomonas. Nws tsis yog ib qho kab mob, tab sis cov nroj tsuag kev loj hlob txhawb cov kab mob uas feem ntau pom hauv av. Yog li ntawd, nws tsis tshua muaj kab mob rau tib neeg.
Daim duab 02: P. fluorescens
P. fluorescens muaj nyob rau hauv ntau qhov chaw nyob nrog rau cov av, rhizospheres, thiab cov chaw ntawm cov nroj tsuag, cov tshuaj tsis muaj tshuaj lom neeg, cov taub hau da dej, thiab txawm nyob sab hauv phab ntsa. Raws li tau lees paub, nws yog ib qho kab mob tseem ceeb hauv ib puag ncig vim nws muaj peev xwm txhawb kev cog qoob loo ntawm kev zais cov tshuaj tua kab mob, cov metabolites theem nrab, sidarophores, thiab lwm yam.
Dab tsi yog Qhov Zoo Sib Txawv Ntawm Pseudomonas aeruginosa thiab Pseudomonas fluorescens ?
- P. fl aeruginosa thiab P. fluorescens yog kab mob gram-negative.
- Lawv ob leeg yog cov kab mob uas tsis yog kab mob.
- Kuj, ob leeg yog cov kab mob aerobic.
- Tsis tas li ntawd, lawv ob leeg yog cov kab mob zoo li tus pas nrig.
- Flagella yog nyob rau hauv ob qho tib si.
- Ob leeg yog flagellated thiab motile.

Summary – Pseudomonas aeruginosa vs Pseudomonas fluorescens
P. aeruginosa thiab P. fluorescens yog ob hom kab mob ntawm cov genus Pseudomonas. P. aeruginosa yog ib hom kab mob uas ua rau muaj kab mob hauv cov nroj tsuag thiab tsiaj txhu, suav nrog tib neeg. P.fluorescens yog hom tsis muaj kab mob, thiab nws tuaj yeem txhawb kev loj hlob ntawm cov nroj tsuag thiab tseem muaj cov khoom siv biocontrolling. Qhov no yog qhov txawv ntawm P. aeruginosa thiab P. fluorescens. Ntxiv mus, P. aeruginosa muaj ib tug polar flagellum thaum P. fluorescens yog multiflagellated.
