Staphylococcus thiab Micrococcus ob leeg yog Gram positive cocci (GPC). Ob leeg ntawm no cocci yog Tsis-motile, tsis-sporing thiab Catalase Positive. Tus tswv cuab ntawm cov genus Staphylococcus yog txuam nrog kev kho mob kis mob whereas ntawm Micrococcus yog tsis tshua muaj kev cuam tshuam rau kev kis kab mob.
Tsis tas li ntawd, qhov txawv ntawm cov pa oxygen ntawm micrococcus thiab ntawm staphylococcus thiab peb tuaj yeem siv cov kev sib txawv no kom paub qhov txawv ntawm micrococcus ntawm staphylococcus?
Ntxiv mus, Micrococcus yog ib cov kab mob aerobic tias tsuas yog hlob nyob rau hauv lub xub ntiag ntawm cov pa thaum Staphylococcus yog facultative anaerobe tias muaj peev xwm siv aerobic lossis anaerobic fermentation. Micrococcus thiab Staphylococcus yog Gram-positive cocci uas yog tsis muaj zog, tsis txhawb nqa, thiab Catalase zoo.
Ib sab saum toj no, dab tsi disk kuaj txawv Staphylococcus epidermidis los ntawm Staphylococcus Saprophyticus? Novobiocin xeem yog siv rau sib txawv coagulase-tsis zoo staphylococci (CONS) thiab presumptively txheeb xyuas qhov cais raws li Staphylococcus saprophyticus (novobiocin resistant). Nws feem ntau yog ua los ntawm cov zis cais tawm (cais los ntawm cov poj niam ntawm pab pawg hnub nyoog muaj me nyuam) uas yog coagulase tsis zoo. S.
Hais txog qhov no, koj yuav txheeb xyuas tus micrococcus li cas?
DIAGNOSIS. Micrococci yog catalase-positive, oxidase-positive, nruj me ntsis aerobic Gram-positive cocci uas loj hlob hauv pawg. Ntawm cov ntshav ntshav agar lawv tsim cov xim xim rau daj daj. Tsis kam mus rau mupirocin thiab staphylolysin, thiab susceptibility rau bacitracin thiab lysozyme txawv lawv ntawm staphylococci.
Puas yog micrococcus coagulase zoo?
Micrococcus luteus yog Gram- zoo , rau Gram-variable, nonmotile, coccus, tetrad-arrangement, pigmented, saprotrophic bacterium uas yog tsev neeg Micrococcaceae. Nws yog urease thiab catalase zoo . M. luteus yog coagulase Tsis zoo, bacitracin susceptible, thiab tsim cov xim daj daj ntawm cov khoom noj agar.

Koj sib txawv li cas ntawm staphylococcus thiab streptococcus?
Staphylococcus thiab Micrococcus spp. yog catalase zoo, hos Streptococcus thiab Enterococcus spp. yog catalase tsis zoo. Yog tias Gram-positive cocci yog catalase zoo thiab xav tias yog staphylococci, kev sim coagulase feem ntau ua tiav
Qhov tseem ceeb ntawm qhov sib txawv ntawm tuab ntawm phab ntsa ntawm aorta yog dab tsi?
Dab tsi yog qhov tseem ceeb ntawm qhov sib txawv ntawm tuab ntawm phab ntsa ntawm aorta thiab phab ntsa ntawm lub ntsws ntsws? Cov phab ntsa tuab ntawm aorta tso cai kom tiv taus siab dua ntawm cov ntshav tso tawm los ntawm lub ventricle
Dab tsi yog qhov txawv ntawm cheeb tsam sib txawv thiab thaj tsam tas li ntawm ib qho tshuaj tiv thaiv?
Cov cheeb tsam sib txawv no, muaj li ntawm 110-130 amino acids, muab cov tshuaj tiv thaiv kab mob nws qhov tshwj xeeb rau kev khi antigen. Cov cheeb tsam sib txawv suav nrog qhov kawg ntawm lub teeb thiab cov saw hnyav. Lub cheeb tsam tas li txiav txim siab cov txheej txheem siv los rhuav tshem antigen
Qhov kev xeem twg tuaj yeem sib txawv ntawm peb hom loj ntawm staphylococcus?
Cov tshuaj tiv thaiv loj rau kev siv hauv kev txheeb xyuas Staphylococcus yog cov tshuaj tiv thaiv coagulase, uas faib cov genus Staphylococcus rau hauv 2 pawg - coagulase tsis zoo hom thiab coagulase zoo hom
Koj tuaj yeem qhia qhov sib txawv ntawm staphylococcus thiab streptococcus li cas?
Staphylococci yog Gram-positive cocci uas loj hlob hauv clumps, yog catalase kuaj tau zoo thiab coagulase kuaj tau zoo (Staph. Streptococci yog Gram-positive cocci uas loj hlob ua khub lossis saw hlau. tsis zoo kuaj catalase
