Burkholderia Mallei yog dab tsi ?
Burkholderia mallei yog kab mob gram-negative, bipolar, aerobic, non-motile, coccobacillary-shaped kab mob uas tsis tshua muaj neeg kis. Qhov loj ntawm cov kab mob yog kwv yees li 1.5-3.0 μm nyob rau hauv ntev thiab 0.5 - 1.0 μm nyob rau hauv txoj kab uas hla nrog rounded xaus. Cov kab mob no ua rau muaj kab mob hu ua glanders. Glanders yog ib hom kab mob sib kis uas tshwm sim feem ntau hauv cov nees, mules, thiab nees luav. Glanders kis mus rau tib neeg los ntawm kev sib cuag ncaj qha nrog cov tsiaj txhu. Cov kab mob no tau hloov zuj zus los ntawm Pseudomallei, uas yog ib hom kab mob zoo sib xws, los ntawm kev xaiv txo qis thiab tshem tawm ntawm Pseudomallei genome. B. mallei tau raug cais tawm thawj zaug hauv xyoo 1882 los ntawm tus kab mob siab thiab tus po ntawm tus nees.
Daim duab 01: B. mallei
Lub genome ntawm B. mallei tau ua raws los ntawm lub koom haum ntawm kev tshawb fawb genomic hauv Tebchaws Meskas. Lub genome loj ntawm cov kab mob no me dua Pseudomallei. Nws muaj chromosome ntawm 3.5M bp thiab plasmid ntawm 2.5 Mbp. Cov kab mob no tuaj yeem rhuav tshem los ntawm tshav kub thiab lub teeb ultraviolet.
Cov tshuaj tua kab mob xws li streptomycin, amikacin, tetracycline, doxycycline, carbapenems, ceftazidime, clavulanicacid, piperacillin, chloramphenicol, thiab sulfathiazole kuj tseem tiv thaiv cov kab mob no. Tab sis nws tiv taus cov tshuaj tua kab mob, suav nrog aminoglycosides, polymyxins, thiab beta-lactams. Tam sim no tsis muaj tshuaj tiv thaiv los tiv thaiv kab mob B. mallei.
Pseudomallei yog dab tsi ?
Pseudomallei yog kab mob gram-negative, bipolar, aerobic, motile, rod-shaped kab mob uas feem ntau kis rau tib neeg. Qhov loj ntawm cov kab mob yog 2-5 μm nyob rau hauv ntev thiab 0.4-0.8 μm nyob rau hauv lub cheeb, thiab nws muaj peev xwm ntawm nws tus kheej-propulsion siv flagella. Nws tseem hu ua Burkholderia pseudomallei lossis Pseudomonas pseudomallei. Nws yog cov kab mob hauv av. Cov kab mob no muaj nyob hauv thaj chaw sov thiab subtropical thoob ntiaj teb. Cov kab mob no ua rau muaj kab mob hu ua melioidosis. Nws kuj muaj peev xwm kis tau cov nroj tsuag.
Daim duab 02: Pseudomallei
Lub genome loj ntawm Pseudomallei yog kwv yees li 7.2 Mbp nrog ib qho loj thiab ib qho me me chromosome. Cov kab mob no muaj cov noob rau fusogenic hom VI secretion system uas yuav tsum tau rau lub cell mus rau cell kis nyob rau hauv mammalian hosts. Nws kuj muaj cov noob los tsim cov tshuaj lom hu ua lethal factor 1. Cov kab mob no raug rau cov tshuaj tua kab mob xws li ceftazidime, chloramphenicol, doxycycline, thiab co-trimoxazole. Ntxiv mus, lawv tiv taus cov tshuaj tua kab mob xws li gentamicin thiab colistin. Tam sim no tsis muaj tshuaj tiv thaiv rau tus kab mob no.

Qhov txawv ntawm Burkholderia Mallei thiab Pseudomallei yog dab tsi?
Burkholderia mallei yog cov kab mob uas tsis yog-motile, coccobacillary zoo li tus kab mob uas tsis tshua kis rau tib neeg. Ntawm qhov tod tes, Pseudomallei yog cov kab mob motile, tus kab mob zoo li tus kab mob uas feem ntau kis rau tib neeg. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm Burkholderia Mallei thiab Pseudomallei. Tsis tas li ntawd, Burkholderia mallei yog ib qho tseem ceeb ntawm cov kab mob mammalian. Pseudomallei yog ib hom kab mob nyob hauv av.
Cov duab hauv qab no nthuav tawm qhov sib txawv ntawm Burkholderia Mallei thiab Pseudomallei hauv daim ntawv teev npe.
Summary – Burkholderia Mallei vs Pseudomallei
Burkholderia mallei thiab Pseudomallei yog ob tus kab mob proteobacteria uas ua rau qog nqaij hlav thiab melioidosis, feem. Txawm hais tias lawv tsis tshua muaj nyob rau sab hnub poob, ob qho tib si kab mob tsis ntev los no tau txais kev saib xyuas ntau vim tias lawv lub peev xwm tshwj xeeb ua cov tshuaj tua kab mob bioterrorism. Burkholderia mallei yog cov kab mob uas tsis yog-motile thiab coccobacillary zoo li tus kab mob. Pseudomallei yog ib hom kab mob motile thiab pas nrig. Burkholderia mallei tsis tshua kis rau tib neeg. Pseudomallei feem ntau kis rau tib neeg. Yog li, qhov no yog cov ntsiab lus ntawm qhov sib txawv ntawm Burkholderia Mallei thiab Pseudomallei.
