Bacteriophages, lossis tsuas yog phages, yog cov kab mob kis kab mob. … Lysogenic hloov dua siab tshiab los ntawm kev koom ua ke ntawm prophages encoding haib toxins yog tej zaum qhov kev txiav txim siab tshaj plaws ntawm prophages rau evolution ntawm cov kab mob pathogenic.
Lub luag haujlwm ntawm Prophages yog dab tsi?
Prophages tsim ib qhov chaw tseem ceeb ntawm kev sib txawv ntawm caj ces thiab kev sib txawv ntawm cov kab mob cuam tshuam nrog kev ua phem ntawm ntau cov kab mob kab mob suav nrog E. coli, 16 , 17 Streptococcus pyogenes, 15, 18, 19 Salmonella enterica, 20 -23 thiab Staphylococcus aureus.
Prophages ua dab tsi?
Prophaages muaj peev xwm ua tau ntau yam hauv lawv cov kab mob sib txawv. Prophages tuaj yeem nce qhov muaj peev xwm ntawm cov kab mob kab mob hauv tib neeg thiab cov kab mob nroj tsuag nrog rau kev ua kom muaj peev xwm ntawm cov kab mob kom muaj sia nyob hauv ib puag ncig hnyav.
Lub luag haujlwm dab tsi muaj cov kab mob bacteriophages ua hauv cov kab mob evolution?
Bacteriophages tuaj yeem nqa cov block DNA loj thiab tuaj yeem muaj sia nyob hnyav uas tshem tawm cov kab mob. Yog li ntawd, DNA tseem ceeb rau cov pej xeem tuaj yeem khaws cia kom txog thaum tus tswv tsev rau lysogenic hloov dua siab tshiab rau hauv ib puag ncig niche.
Lysogeny pab txhawb rau cov kab mob li cas?
txheej txheem no hu ua lysogenic hloov dua siab tshiab. Qee cov lysogenic phage nqa cov noob uas tuaj yeem txhim kho kev ua phem ntawm cov kab mob… Cov noob no, ib zaug ua ke rau hauv cov kab mob chromosome, tuaj yeem ua rau cov kab mob tsis zoo ib zaug tso tawm cov co toxins uas tuaj yeem ua rau kab mob.
