Tsis tas li ntawd, yim ntawm 32 nuc- Staphylococcus aureus zoo nyob ib leeg DNase tsis zoo (25%). Rao et al tau tshaj tawm DNase tsis zoo Staphylococcus aureus tab sis tsis muaj kev piav qhia rau cov kev tshawb pom no [18]. coagulans, uas raws li National Standard Method kuj yog DNase zoo [9].
Tom qab ntawd, ib tus tuaj yeem nug, Staphylococcus aureus puas tsim DNase?
Deoxyribonuclease ( DNase ) yog ib qho enzyme uas rhuav tshem DNA. Qee hom kab mob muaj peev xwm ua tau tsim tawm cov DNase enzyme- Staphylococcus aureus , Staphylococcus nruab nrab, Staphylococcus hyicus, Pawg A Streptococcus, thiab Serratia marcescens.
Qhov thib ob, Staphylococcus aureus citrate puas zoo? Phenotypic Identification ntawm Staphylococcus aureus Ib pawg neeg nyob ib leeg tau sim nrog tube coagulase thiab DNase kuaj thiab kev loj hlob ntawm MSA. Txij li thaum citrate yog siv los ntawm enterococci [16], dawb huv colonies ntawm Gram zoo , Catalase zoo staphylococci (kev ntsuam xyuas catalase ua ntej coagulase tshua) tau siv.
Ntxiv mus, qhov ntsuas DNase zoo txhais li cas?
Zoo . A zoo qhov tshwm sim yog tus yam ntxwv tsis muaj xim nyob ib puag ncig xeem kab mob. Nws txhais tau tias tias cov kab mob uas raug kuaj muaj peev xwm los hydrolyze DNA. Piv txwv ntawm DNase test positive Cov kab mob yog: Staphylococcus aureus.
Vim li cas Staphylococcus aureus catalase zoo?
Keeb kwm: Staphylococcus aureus yog ib qho ntawm cov kab mob phem tshaj plaws zoo kab mob. Nws tsim ntau cov co toxins thiab cov enzymes, feem ntau yog cov kab mob virulent. Ntawm cov enzyme uas tsim tawm yog catalase uas muaj txiaj ntsig zoo hauv kev sib txawv staphylococci los ntawm streptococci [1]. Txuj catalase ua S.

Puas yog potassium yog qhov zoo lossis tsis zoo Chronotropic?
Zoo chronotropic thiab tsis zoo inotropic cuam tshuam los ntawm poov tshuaj chloride nyob rau hauv cais canine atrium. Los ntawm cov txiaj ntsig no, nws tau txiav txim siab tias cov poov tshuaj muaj qhov cuam tshuam tsis zoo rau atrial contractility thiab cuam tshuam ncaj qha rau atrial tus nqi
Staphylococcus aureus puas tsim catalase?
Yav dhau los: Staphylococcus aureus yog ib qho ntawm cov kab mob muaj kab mob zoo tshaj plaws Ntawm cov enzyme uas tsim tawm yog catalase uas muaj txiaj ntsig zoo hauv kev sib txawv ntawm staphylococci los ntawm streptococci [1]. Catalase yog ze li ntawm ubiquitous ntawm qee cov kab mob uas tuaj yeem loj hlob nyob rau hauv lub xub ntiag ntawm oxygen (cua)
