Thaum kev ncua ntawm cov kab mob loj hlob hauv cov kua nruab nrab tau ua rau kev tshawb pom ntawm cov yam ntxwv tseem ceeb ntawm microbial physiology thiab noob caj noob ces, nyob rau hauv cov kab mob tsis tshua loj hlob li axenic planktonic kab lis kev cai. Hloov chaw, lawv feem ntau muaj xws li cov zej zog ntawm cov hlwb tsis muaj zoguas tsim los ua biofilms [1–3].
Puas muaj cov hlwb planktonic tuaj yeem pom hauv biofilms?
Lub peev xwm ntawm cov hlwb planktonic tsim biofilm yog tsim tau zoo thiab ua qauv qhia los ntawm ntau hom kab lis kev cai ntshiab hauv vitro.
Yuav ua li cas biofilms txawv ntawm planktonic hlwb?
Biofilms yog tiag tiag hnyav tua los ntawm cov kab mob bactericidal antimicrobials, piv rau logarithmic-theem planktonic hlwb, thiab yog li ua rau pom kev ua siab ntev. Nws tau xav tias biofilms kuj tseem muaj peev xwm tiv taus ntau dua li cov kab mob nyob ruaj khov-phase planktonic.
Peb pom cov hlwb dab tsi hauv biofilms?
Biofilms yog ib pawg ntawm ib lossis ntau hom kab mob uas tuaj yeem loj hlob ntawm ntau qhov chaw sib txawv. Cov kab mob uas tsim biofilms suav nrog kab mob, fungi thiab protists. Ib qho piv txwv ntawm biofilm dental plaque, slimy buildup ntawm cov kab mob uas tsim rau ntawm cov hniav.
Planktonic hlwb yog dab tsi?
Planktonic hlwb txhais tau hais tias " raws li cov kab mob dawb ntws hauv kev ncua" as. tawm tsam lub xeev sessile (lub npe hu ua biofilm): "aCov kab mob sib xyaw ua ke ntawm cov kab mob. hlwb nyob rau hauv ib tug self-tsim polymeric matrix thiab adherent rau ib tug inert los yog nyob. nto" raws li tau hais los ntawm Costerton thiab cov neeg ua haujlwm ua haujlwm (1999).
