Qhov Tseem Ceeb Qhov txawv - Encystment vs Excystment

Lub dormant theem ntawm cov kab mob hu ua cyst. Lub cyst feem ntau pab txhawb kev ciaj sia ntawm cov kab mob (cov kab mob los yog cov kab mob protists) nyob rau hauv ib puag ncig tsis zoo xws li cov as-ham tsis txaus thiab cov pa oxygen, qhov kub thiab txias, muaj cov tshuaj lom thiab tsis muaj dej noo thiab lwm yam. Lub cyst yog cov qauv tuab-walled thiab tsis yog. suav tias yog ib lub cell ua me nyuam. Lub hom phiaj ib leeg ntawm lub cyst yog kom paub tseeb tias cov kab mob muaj sia nyob mus txog rau qhov chaw ib puag ncig rov qab los rau qib qub thiab muaj txiaj ntsig zoo. Encystment yog txheej txheem uas cov kab mob sab hauv feem ntau nyob rau hauv cov theem larval yog nyob rau hauv ib lub cyst. Yog li ntawd, cov txheej txheem encystment pab cov kab mob kis tau yooj yim mus rau ib puag ncig zoo lossis txav ntawm ib tus tswv tsev mus rau lwm qhov. Thaum cov kab mob mus txog qhov chaw zoo tom qab encystment, phab ntsa ntawm lub cyst ruptures los ntawm ib tug txheej txheem hu ua encystment. Qhov sib txawv tseem ceeb ntawm encystment thiab excystment yog tias qhov encystment yog txheej txheem ntawm cyst tsim qhov kev zoo siab yog cov txheej txheem ntawm kev khiav tawm ntawm lub cyst.

Kev nkag siab yog dab tsi?

Lub cyst yog cov qauv tsim los tiv thaiv qee yam kab mob hauv cov xwm txheej tsis zoo. Nws yog ib tug resilient, quiescent theem ntawm lub cev. Tag nrho cov haujlwm metabolic raug kaw nyob rau theem cyst. Lub cyst muaj kev tiv thaiv sab nraud uas tiv taus qhov hnyav xws li kub, txias, qhuav, tshuaj lom neeg, pH thiab lwm yam. Cov txheej txheem tsim ntawm cyst yog hu ua encystment. Nyob rau hauv cov xwm txheej tsis zoo, encystment tshwm sim thaum cov stimulating yam tshwm sim los ntawm kev hloov ib puag ncig. Qee qhov stimulatory yam yog cov pa oxygen tsawg, lub cev qhuav dej, hloov pH, zaub mov tsis txaus thiab lwm yam.

Daim duab 01: Encystment

Cyst tsim muaj nyob rau hauv cov kab mob thiab protozoa. Thaum lub sij hawm encystment txheej txheem, cov kab mob sab hauv feem ntau nyob rau hauv cov theem larval yog nyob rau hauv ib lub cyst. Yog li ntawd, cov txheej txheem encystment pab cov kab mob kis tau yooj yim mus rau ib puag ncig zoo lossis txav ntawm ib tus tswv tsev mus rau lwm qhov. Lub cell phab ntsa muaj pes tsawg leeg ntawm cov hlwv yog sib txawv raws li cov kab mob sib txawv. Lub cyst phab ntsa ntawm cov kab mob yog tuab vim muaj cov txheej txheem peptidoglycan thaum cov phab ntsa protozoan cyst yog tsim los ntawm chitin.

Kev Excystment yog dab tsi?

Thaum cov kab mob mus txog qhov chaw zoo tom qab encystment, phab ntsa ntawm lub cyst ruptures los ntawm tus txheej txheem hu ua excystation. Cov txheej txheem uas ruptures cyst phab ntsa thiab khiav los ntawm nws yog hu ua excystment. Excystment tshwm sim nyob rau hauv cov xwm txheej zoo. Qee cov kab mob protozoan tau kaw hauv cov hlwv sab nraum tus tswv tsev. Thaum cov cysts nkag mus rau hauv tus tswv tsev raug, lawv tawm los ntawm cov hlwv thiab ua rau muaj kev phom sij rau tus tswv tsev. Txhawm rau tiv thaiv cov kab mob los ntawm cov kab mob protozoan (xws li Amoeba, Giardia) cov txheej txheem ntawm encystment thiab excystment yuav tsum thaiv. Nws tuaj yeem ua tau los ntawm kev ua cov kauj ruam los cuam tshuam lawv lub neej voj voog.

Daim duab 02: Excystment

Excystment yog tus txheej txheem antagonistic ntawm encystment. Nws tsim cov noob qoob loo uas tuaj yeem rov qab mus rau kev loj hlob thiab kev loj hlob theem.

Dab tsi yog qhov zoo sib xws ntawm Encystment thiab Excystment?

  • Ob leeg yog cov txheej txheem cuam tshuam txog kev muaj sia nyob ntawm lub cev. Cov no yog ob lub tswv yim ciaj sia siv los ntawm cov kab mob.
  • Ob txheej txheem koom nrog cov qauv dormant hu ua cyst.
  • Ob txheej txheem yog genetic encoded.

Qhov txawv ntawm Encystment thiab Excystment yog dab tsi?

Kev sib tw vs Kev ua siab ntev

Encystment yog txheej txheem ntawm cyst tsim. Excystment yog txheej txheem ntawm kev khiav tawm ntawm cov hlwv.
Xwm txheej
Encystment tshwm sim thaum lub sijhawm tsis zoo. Excystment tshwm sim thaum lub sijhawm muaj kev zoo siab.
Kev pab kom muaj sia nyob hauv ib puag ncig hnyav. Excystment pab kom tawm ntawm lub cyst thiab loj hlob nyob rau hauv cov xwm txheej zoo.
Cov Qauv Ua Haujlwm
Lub encystment tsim ib lub cell dormant. Ib tug vegetative cell emerges ntawm excystment.

Summary – Encystment vs Excystment

Lub cyst yog ib theem dormant ntawm cov kab mob los yog protozoa uas pab txhawb lawv txoj sia nyob thaum lub sijhawm ib puag ncig tsis zoo. Cysts tsim tau zoo heev pab cov kab mob no hloov mus rau ib puag ncig. Ensytment thiab excystment yog ob txoj kev koom tes hauv cov txheej txheem no. Encystment yog txheej txheem tsim cyst thaum lub sijhawm tsis zoo. Excystment yog rupture ntawm cyst phab ntsa thiab khiav tawm ntawm lub cyst thaum lub sij hawm zoo. Qhov no yog qhov txawv ntawm encystment thiab excystment.
