Qhov sib txawv tseem ceeb ntawm Enterococcus thiab Streptococcus yog tias Enterococci feem ntau tsis muaj hemolytic (gamma helolytic) thaum Streptococci yog hemolytic (alpha thiab beta hemolytic).
Enterococcus thiab Streptococcus yog ob hom kab mob lactic acid. Ob lub genera muaj xws li cov kab mob zoo li tus kheej kheej uas yog cov kab mob gram-zoo, uas tsis yog-sporing, nonmotile cocci thiab facultative anaerobes.
YEnterococcus yog dab tsi?
Enterococcus yog ib hom kab mob uas muaj cov kab mob gram-positive, non-spore forming, catalase negative, spherical zoo li tus kab mob. Nws feem ntau tshwm sim li diplococci. Txawm li cas los xij, qee qhov ntawm lawv tsim cov saw luv luv. Ntxiv mus, lawv yog cov facultative anaerobes uas tuaj yeem ua pa hauv ob qho tib si oxygen nplua nuj thiab tsis muaj oxygen. Tsis tas li ntawd, cov kab mob no tseem hu ua kab mob lactic acid vim lawv muaj peev xwm tsim cov lactic acids los ntawm carbohydrate fermentation.
Daim duab 01: Enterococcus
Enterococci nyiam muaj sia nyob hauv tib neeg txoj hnyuv, thiab lawv dhau los ua cov kab mob kis tau zoo thaum cov xwm txheej zoo rau cov kab mob. E. faecalis thiab E. faecium yog ob hom uas feem ntau ua rau tib neeg muaj kab mob. Qee cov kab mob uas tshwm sim los ntawm cov kab mob no yog kab mob hauv lub cev, kab mob endocarditis, kab mob biliary tract, suppurative abnormal lesions.
Streptococcus yog dab tsi?
Streptococcus yog cov kab mob genus uas suav nrog ntau hom kab mob gram-zoo, uas tsis yog-spores tsim cov kab mob. Lawv yog spherical nyob rau hauv cov duab, thiab li no, lub npe 'coccus'. Lawv muaj nyob rau hauv khub los yog chains zoo li Enterococci. Feem ntau ntawm cov kab mob no yog facultative anaerobes thaum qee qhov yog obligate anaerobes. Tsis tas li ntawd, cov kab mob no tsim cov lactic acids los ntawm fermentation ntawm carbohydrates. Vim cov cuab yeej no, lawv ua cov kab mob tseem ceeb hauv kev lag luam mis nyuj. Tsis tas li ntawd, lawv yog catalase tsis zoo. Lawv tsis muaj flagella, thiab yog li ntawd, lawv yog nonmotile.
Daim duab 02: Streptococci
Streptococci yog cov kab mob thiab cov lus pom zoo hauv cov mucosal daim nyias nyias ntawm cov kab mob ua pa sab saud, thiab qee qhov nyob hauv cov hnyuv ib yam nkaus. Cov kab mob uas tshwm sim los ntawm lawv tuaj yeem kho tau yooj yim los ntawm penicillin thiab lwm yam tshuaj tua kab mob vim lawv muaj ntau yam tshuaj tua kab mob. S. pyogenes, S. pneumonia, S. suis, S. agalactiae, S. mitis, S. oralis, S. sanguis thiab S. gordonii yog qee hom kab mob Streptococci thiab tseem ceeb rau kev kho mob.
Dab tsi yog qhov zoo sib xws ntawm Enterococcus thiab Streptococcus ?
- Ob leeg Enterococcus thiab Streptococcus yog cov kab mob genera thiab belongs rau phylum firmicutes.
- Lawv yog ob hom kab mob gram-zoo.
- Thiab ob qho tib si yog kheej kheej, yog li lub npe coccus.
- Ntxiv mus, lawv ob leeg yog facultative anaerobes.
- Ob leeg tshwm sim hauv khub lossis chains.
- Ob leeg yog plab hnyuv commensals.
- Ntxiv mus, lawv ob leeg yog cov muaj zog carbohydrate fermenters thiab tsim cov lactic acids.
Qhov txawv ntawm Enterococcus thiab Streptococcus yog dab tsi?

Summary – Enterococcus vs Streptococcus
Enterococcus thiab Streptococcus yog ob hom kab mob gram-zoo. Ob genera muaj xws li non-spore forming, nonmotile, facultative anaerobes. Cov kab mob nyob rau hauv ob lub genera yog spherical nyob rau hauv cov duab thiab tshwm sim nyob rau hauv diplococci los yog luv chains. Enterococci feem ntau yog nonhemolytic thaum Streptococci yog hemolytic. Qhov no yog qhov sib txawv tseem ceeb ntawm Enterococcus thiab Streptococcus.
