Qhov Tseem Ceeb Qhov txawv - Obligate Intracellular Parasite vs Bacteriophage
Ib tug kab mob yog ib yam kab mob uas nyob hauv thiab lwm yam kab mob, muab cov khoom noj los ntawm lawv. Qee cov kab mob tag nrho nyob ntawm tus tswv tsev thaum muaj qee qhov nyob ntawm ib nrab. Lawv hu ua tag nrho cov kab mob thiab cov kab mob ib nrab, feem. Obligate intracellular parasites yog ib pawg ntawm cov kab mob uas tsis muaj peev xwm rov tsim tawm sab nraud ntawm tus tswv tsev cell. Muaj ntau hom obligate intracellular parasites. Ib tug bacteriophage yog ib hom ntawm lawv. Bacteriophage yog tus kab mob uas tawm tsam cov kab mob thiab rov ua dua siv cov kab mob sib kis. Lawv yog cov kab mob ntau tshaj plaws hauv biosphere. Lawv txuas mus rau phab ntsa ntawm cov kab mob thiab txhaj lawv cov nucleic acid rau cov kab mob. Hauv cov kab mob, kab mob genome replicates thiab ua cov khoom tsim nyog thiab cov enzymes los ua ntau cov kab mob tshiab. Qhov sib txawv tseem ceeb ntawm obligate intracellular parasite thiab bacteriophage yog tias obligate intracellular parasite yog txhua yam kab mob, suav nrog tus kab mob, kab mob, protozoan, thiab fungus, uas tsis tuaj yeem tsim dua tshiab yam tsis muaj lub xov tooj ntawm tes thaum bacteriophage yog tus kab mob kab mob hauv lub cev uas kis tau thiab rov ua dua. hauv kab mob.
Dab tsi yog Obligate Intracellular Parasite?
Lo lus 'obligate' txhais tau tias ' nruj' lossis 'yuav tsum'. Intracellular txhais tau tias hauv lub cell. Parasite yog ib yam kab mob uas nyob hauv lossis lwm yam kab mob thiab tau txais cov khoom noj los ntawm nws. Yog li, lub luag haujlwm ntawm cov kab mob hauv lub cev tuaj yeem txhais tau tias yog cov kab mob uas nyob ntawm tag nrho lwm cov kab mob 'intracellular peev txheej rau kev ciaj sia thiab kev yug me nyuam. Cov kab mob no rov tsim dua nyob rau hauv lub tswv tsev cell los ntawm kev ua tus kab mob. Lawv tsis tuaj yeem tsim tawm sab nraud ntawm cov tswv tsev. Muaj ntau hom obligate intracellular parasites. Tag nrho cov kab mob suav nrog cov kab mob bacteriophages yog cov kab mob hauv nruab nrog cev. Qee cov kab mob xws li Chlamydia, Rickettsia, Coxiella, qee hom kab mob Mycobacterium yog cov kab mob no. Tseem muaj obligate intracellular fungal thiab protozoan hom xws li Pneumocystis, Plasmodium, Cryptosporidium, Leishmania, thiab Trypanosoma.
Daim duab 01: Obligate intracellular parasite Toxoplasma gondii
Cov kab mob intracellular tsis tuaj yeem tsim tawm sab nraud ntawm tus tswv tsev cell. Yog li ntawd, nws yog ib qhov nyuaj rau loj hlob lawv thiab kawm nyob rau hauv lub chaw soj nstuam. Txawm li cas los xij, qee cov kws tshawb fawb tau kawm txog Q - ua npaws cab Coxiella burnetti siv cov txheej txheem uas pab txhawb kev loj hlob ntawm axenic kab lis kev cai ntawm nws. Lawv tau tawm tswv yim tias tib cov txheej txheem tuaj yeem siv los kawm txog lwm cov kab mob hauv nruab nrog cev thiab.
Cov kab mob hauv lub cev ua rau cov kab mob ua kom tus tswv ciaj sia vim lawv xav tau cov as-ham los ntawm tus tswv kom loj hlob thiab rov tsim dua. Qee cov kab mob txhawb nqa cov kab mob 'protein self-degradation. Lawv siv cov proteins uas degraded hauv daim ntawv ntawm cov amino acids ua lawv lub zog.
Bacteriophage yog dab tsi?
A bacteriophage (phage) yog tus kab mob uas kis tau thiab nthuav tawm hauv cov kab mob tshwj xeeb. Tag nrho cov kab mob bacteriophages yog obligate intracellular parasites. Lawv xav tau tus kab mob tus tswv tsev kom rov tsim dua. Lawv tseem hu ua cov kab mob noj vim lawv cov kab mob bactericidal. Bacteriophages tau tshawb pom los ntawm Frederick W. Twort hauv xyoo 1915, thiab lawv tau raug hu ua bacteriophages los ntawm Felix d'Herelle hauv xyoo 1917. Lawv yog cov kab mob ntau tshaj plaws hauv ntiaj teb. Cov kab mob bacteriophage yog tsim los ntawm ob yam tseem ceeb: genome thiab protein capsid. Lub genome tuaj yeem yog DNA lossis RNA. Tab sis feem ntau ntawm cov kab mob bacteriophages muaj ob-kab DNA genome.
Bacteriophages yog tshwj xeeb rau ib tus kab mob lossis ib pawg kab mob tshwj xeeb. Lawv muaj npe los ntawm cov kab mob uas lawv kis tau. Piv txwv li, bacteriophage uas kis tau E coli yog hu ua coliphage. Bacteriophages nyob rau hauv cov duab sib txawv. Ntawm lawv, lub taub hau thiab tus Tsov tus tw yog qhov zoo tshaj plaws.
Daim duab 02: Bacteriophage
Bacteriophages yuav tsum kis tus tswv cell kom rov tsim dua. Lawv txuas nruj nreem rau ntawm phab ntsa ntawm cov kab mob uas siv lawv cov receptors saum npoo thiab txhaj lawv cov khoom siv caj ces rau hauv lub cell. Bacteriophages tuaj yeem kis tau ob hom kab mob hu ua lytic thiab lysogenic voj voog, nyob ntawm seb hom phage. Hauv lub voj voog lytic, bacteriophages kis cov kab mob thiab tua cov kab mob sai sai los ntawm lysis. Nyob rau hauv lub voj voog lysogenic, cov khoom siv tshuaj tua kab mob ua ke nrog cov kab mob genome lossis plasmids thiab muaj nyob rau hauv lub xov tooj ntawm tes rau ob peb mus rau txhiab tiam yam tsis tua tus kab mob tus tswv.
Phages muaj ntau yam kev siv hauv molecular biology. Lawv siv los kho cov kab mob pathogenic cov kab mob uas tiv taus cov tshuaj tua kab mob. Lawv kuj tuaj yeem siv los txheeb xyuas cov kab mob tshwj xeeb hauv kev kuaj kab mob.
Dab tsi zoo sib xws ntawm Obligate Intracellular Parasite thiab Bacteriophage?
- Ua kom muaj kab mob hauv lub cev thiab cov kab mob bacteriophages xav tau cov kab mob muaj sia kom rov tsim dua
- Ob hom tsis tuaj yeem tsim tawm sab nraud ntawm lub hlwb.

Summary – Obligate Intracellular Parasite vs Bacteriophage
Obligate intracellular parasite yog ib yam kab mob uas tsis tuaj yeem tsim tawm sab nraud ntawm tus tswv tsev cell. Muaj ntau hom obligate intracellular parasites tuaj yeem pom. Ntawm lawv, kab mob, kab mob, fungi, thiab protozoans paub zoo. Bacteriophages yog ib hom kab mob uas muaj kab mob hauv lub cev. Siv cov kab mob replication mechanisms, bacteriophages replicate lawv genomes thiab ua ntau cov ntawv luam ntawm phages tshiab nyob rau hauv lub host cell. Qhov no yog qhov txawv ntawm obligate intracellular parasite thiab bacteriophage.
