Nws zoo li cas hais txog biofilms ? Cov kab mob hlwb zais cov molecules uas tuaj yeem kuaj pom los ntawm lwm cov kab mob. Quorum sensing tso cai rau cov kab mob kom nkag siab qhov concentration ntawm cov teeb liab molecules los saib xyuas cov cell hauv zos. Cov kab mob siv pawg ntseeg los tswj qee tus cwj pwm, xws li biofilm ntau lawm.

Tsis tas li ntawd, dab tsi yog quorum sensing nyob rau hauv biofilms?

Abstract. Ntau tus kab mob tau paub los tswj lawv cov kev sib koom tes thiab cov txheej txheem physiological los ntawm lub tshuab hu ua pawg ntseeg (QS), uas cov kab mob hlwb sib txuas lus nrog ib leeg los ntawm kev tso tawm, kev paub thiab teb rau me me diffusible teeb liab molecules.

Ib tug kuj yuav nug hais tias, dab tsi ua rau pawg ntseeg paub? Quorum sensing yog cov kev cai ntawm cov noob qhia nyob rau hauv teb rau kev hloov pauv hauv cell-population density. Quorum sensing Cov kab mob tsim thiab tso tawm cov teeb liab tshuaj lom neeg hu ua autoinducers uas nce hauv cov concentration raws li kev ua haujlwm ntawm cell ceev.

Kev paub txog pawg ntseeg muaj feem cuam tshuam txog kev tsim biofilm li cas?

Cov kab mob siv pawg ntseeg los tswj tej yam phenotypes, uas nyob rau hauv lem, tswj lawv tus cwj pwm. Qee cov phenotypes muaj xws li biofilm tsim , virulence factor qhia, thiab motility. Qee cov kab mob muaj peev xwm siv tau pawg ntseeg los tswj bioluminescence, nitrogen fixation thiab sporulation.

Dab tsi yog quorum sensing thiab qhov no cuam tshuam li cas rau kev tsim tshuaj tua kab mob?

Ntau tus kab mob siv lub xov tooj ntawm tes sib txuas lus hu ua pawg ntseeg los tswj cov pej xeem ceev-raws li kev hloov pauv ntawm tus cwj pwm. Quorum sensing koom nrog ntau lawm ntawm thiab teb rau diffusible los yog secreted signals, uas muaj peev xwm sib txawv heev nyob rau hauv ntau hom kab mob.
