Yog li ntawd, Micrococcus luteus ua dab tsi?
Ib tug obligate aerobe, M. lus muaj nyob rau hauv av, hmoov av, dej thiab huab cua, thiab raws li ib feem ntawm ib txwm flora ntawm mammalian daim tawv nqaij. Cov kab mob kuj colonizes tib neeg lub qhov ncauj, mucosae, oropharynx thiab sab sauv ib ntsuj av. Nws tau tshawb pom los ntawm Sir Alexander Fleming ua ntej nws nrhiav pom penicillin hauv xyoo 1928.
Tsis tas li ntawd, Micrococcus luteus loj hlob li cas? Tej yam kev mob rau kev loj hlob: Aerobic. Nws qhov kub zoo tshaj plaws rau kev loj hlob yog 25 ° txog 37 ° C. Nws ua tau loj hlob ntawm 45 ° C thiab hauv 10% Sodium Chloride. Nws yuav loj hlob ntawm ntau yam xov xwm xws li Tryptic Soy Agar, Standard Methods Agar, Nutrient Agar, thiab Sheep Blood Agar.
Tsis tas li lo lus nug yog, puas yog Micrococcus luteus tsim kev puas tsuaj rau tib neeg?
Cov txiaj ntsig tseem ceeb ntawm kev noj qab haus huv thiab kev nyab xeeb (kev phom sij) Tsis muaj pov thawj hauv cov ntaub ntawv tshawb fawb los qhia tias Lub micrococcus luteus Hom ATCC 4698 yuav muaj kev cuam tshuam tsis zoo rau tib neeg noj qab haus huv. Hauv Tib neeg Micrococcus luteus feem ntau suav hais tias tsis yog-pathogenic thiab tsis tshua muaj cais tawm ntawm cov ntaub so ntswg puas.
Micrococcus nyob qhov twg?
Micrococci tau raug cais tawm ntawm tib neeg cov tawv nqaij, tsiaj txhu thiab khoom noj siv mis, thiab npias. Lawv yog pom hauv ntau qhov chaw hauv ib puag ncig, suav nrog dej, plua plav, thiab av. M. luteus ntawm tib neeg daim tawv nqaij hloov cov tebchaw hauv hws mus rau hauv cov tebchaw nrog cov ntxhiab tsw tsw qab.

Dab tsi yog qhov tseem ceeb tshaj plaws uas yuav tsum muaj rau cov kua dej ntws hauv cov kav dej Dab tsi lwm yam cuam tshuam rau cov dej ntws?
Thaum ib qho kev quab yuam sab nraud yog exerted rau ntawm cov kua uas muaj, qhov tshwm sim siab yog kis sib npaug thoob plaws hauv cov kua. Yog li txhawm rau kom dej ntws, dej xav tau qhov sib txawv siab. Cov kav dej kuj tuaj yeem cuam tshuam los ntawm cov kua dej, cov yeeb nkab loj, qhov kub thiab txias (cov kav dej khov), cov kua dej ntom ntom
