Qhov sib txawv tseem ceeb ntawm alpha beta thiab gamma hemolysis yog tias alpha hemolysis yog kev puas tsuaj ib nrab ntawm cov qe ntshav liab hauv cov ntshav thiab beta hemolysis yog kev puas tsuaj tag nrho ntawm cov qe ntshav liab hauv cov ntshav, thaum gamma hemolysis tsis koom nrog. kev tawg ntawm cov qe ntshav liab.
cov qe ntshav liab muaj hemoglobin molecules. Hemoglobin yog ib qho hlau uas muaj metalloprotein thiab lub ntsiab molecule ntawm oxygen thauj mus los. Lawv pom nyob rau hauv cov qe ntshav liab. Kev puas tsuaj ntawm cov qe ntshav liab ua rau tso tawm hemoglobin los ntawm cov qe ntshav liab mus rau cov ntshav plasma. Qhov no yog txheej txheem hu ua hemolysis. Ib tug kab mob enzyme hu ua hemolysin catalyzes cov qe ntshav liab. Muaj peb hom hemolysis li alpha hemolysis, beta hemolysis thiab gamma hemolysis.
Alpha Hemolysis yog dab tsi?
Alpha hemolysis lossis tsis tiav hemolysis yog txheej txheem ntawm kev puas tsuaj ib nrab ntawm cov qe ntshav liab. Alpha hemolysin enzyme catalyzes cov txheej txheem no. Nws yog cov kab mob enzyme uas tsim los ntawm ntau hom kab mob xws li S. pneumoniae, Streptococcus mitis, S. mutans, thiab S. salivarius, thiab lwm yam.
Daim duab 01: Alpha Hemolysis
Thaum cov kab mob no loj hlob hauv cov ntshav agar nruab nrab nyob ib ncig ntawm lawv cov cheeb tsam, cov xim ntsuab tshwm sim vim kev puas tsuaj ntawm cov qe ntshav liab tsis tiav. Cov xim ntsuab yog vim muaj cov biliverdin, thiab qhov sib xyaw no yog cov khoom lag luam ntawm hemoglobin tawg.
Beta Hemolysis yog dab tsi?
Beta hemolysis lossis ua tiav hemolysis yog kev puas tsuaj tag nrho ntawm cov qe ntshav liab. Cov kab mob hemolysis rhuav tshem cov cell membranes ntawm cov qe ntshav liab. Thaum lub cell qhib, hemoglobin molecules tawm. Beta hemolysis tshwm sim vim muaj cov kab mob enzyme hu ua beta hemolysin. Bacteria-producing beta hemolysin hu ua beta-hemolytic bacteria, thiab cov hom kab mob yog S. pyogenes thiab S. agalactiae.
Daim duab 02: Beta Hemolysis
Thaum cov kab mob no loj hlob hauv cov ntshav agar nruab nrab, lawv tso beta hemolysin rau hauv nruab nrab. Beta hemolysins rhuav tshem cov qe ntshav liab kom tiav. Yog li ntawd, thaj chaw ntshiab yog tsim nyob ib ncig ntawm cov kab mob kab mob. Kev tsim cov cheeb tsam ntshiab nyob ib puag ncig cov kab mob kab mob yog qhov zoo siv rau kev txheeb xyuas cov kab mob beta-hemolytic.
Gamma Hemolysis yog dab tsi?
Gamma hemolysis yog thib peb ntawm cov tshuaj tiv thaiv hemolysis. Nws hais txog qhov tsis muaj kev puas tsuaj ntawm cov qe ntshav liab. Qhov no yog vim tsis muaj hemolysin. Cov kab mob tsis tsim hemolysin enzymes uas yog qhov tseem ceeb rau kev tawg ntawm cov qe ntshav liab. Thaum tsis muaj hemolysin enzyme, kev tawg ntawm cov qe ntshav liab tsis tshwm sim. Yog li ntawd, nyob rau hauv gamma hemolysis, tsis muaj clearing yuav tshwm sim.
Daim duab 03: Peb hom Hemolysis
Cov kab mob uas ua rau gamma hemolysis hu ua gamma hemolytic lossis cov kab mob uas tsis yog hemolytic. Gamma hemolysis yog tus yam ntxwv ntawm Enterococcus faecalis. Qhov tseeb, tag nrho cov genus ntawm Enterococcus yog cais raws li gamma-hemolytic.
Dab tsi zoo sib xws ntawm Alpha Beta thiab Gamma Hemolysis?
- Alpha, beta thiab gamma hemolysis yog peb hom hemolysis.
- Lawv yog raws li kev puas tsuaj ntawm cov qe ntshav liab.
- ntshav agar yog ib qho nruab nrab siv los soj ntsuam hemolysis.
- Cov kab mob muaj lub luag haujlwm rau tag nrho peb hom hemolysis.
Qhov txawv ntawm Alpha Beta thiab Gamma Hemolysis yog dab tsi?
Nyob rau hauv alpha hemolysis, peb soj ntsuam ib feem puas ntawm cov qe ntshav liab thaum nyob rau hauv beta hemolysis, peb tuaj yeem pom kev puas tsuaj tag nrho ntawm cov qe ntshav liab. Txawm li cas los xij, hauv gamma hemolysis, kev puas tsuaj ntawm cov qe ntshav liab tsis tshwm sim. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm alpha beta thiab gamma hemolysis. Cov kab mob alpha hemolytic tsim alpha hemolysis hauv alpha hemolysis thaum cov kab mob beta hemolytic tsim beta hemolysis hauv beta hemolysis. Tab sis, kab mob gamma hemolytic tsis tsim hemolysins.
Cov hauv qab no qhia txog qhov sib txawv ntawm alpha beta thiab gamma hemolysis.
Summary – Alpha Beta vs Gamma Hemolysis
Hemolysis yog kev tawg ntawm cov qe ntshav liab los ntawm cov kab mob enzymes. Ntau cov kab mob muaj peev xwm tsim cov enzymes hemolysin. Muaj peb hom hemolytic cov tshuaj tiv thaiv xws li alpha hemolysis, beta hemolysis thiab gamma hemolysis. Hauv alpha hemolysis, qhov ua tsis tiav ntawm cov qe ntshav liab tshwm sim. Yog li ntawd, thaj chaw xim ntsuab yog tsim nyob ib ncig ntawm cov kab mob kab mob loj hlob ntawm cov ntshav agar daim hlau. Hauv beta hemolysis, kev puas tsuaj tag nrho ntawm cov qe ntshav liab tshwm sim. Yog li ntawd, thaj chaw ntshiab yog tsim nyob ib ncig ntawm cov kab mob kab mob hauv cov ntshav agar daim hlau. Hauv gamma hemolysis, cov qe ntshav liab tsis raug puas tsuaj vim tsis muaj hemolysin enzymes. Yog li, tsis muaj kev tshem tawm yuav tshwm sim hauv gamma hemolysis. Yog li, qhov no qhia txog qhov sib txawv ntawm alpha beta thiab gamma hemolysis.
