Qhov Tseem Ceeb Qhov txawv - Adenovirus vs Retrovirus
Viruses yog cov kab mob sib kis uas muaj peev xwm kis tau ob qho tib si eukaryotic thiab prokaryotic hosts. Lawv yog obligatory intracellular parasites uas yog tus tswv tsev tshwj xeeb. Cov kab mob feem ntau yog cov kab mob pathogenic, thiab yog li lawv raug suav tias yog cov kab mob ua rau ntau yam kab mob. Cov kab mob uas kis tau rau tib neeg tuaj yeem raug cais raws li adenoviruses thiab retroviruses. Adenoviruses yog cov kab mob uas tsis nyob hauv lub hnab, thiab lawv muaj peev xwm kis tau rau tib neeg tus tswv. Retroviruses yog ib leeg-stranded zoo-sensitive RNA uas muaj cov kab mob uas muaj nyob rau hauv cov xwm, thiab uas muaj ib tug DNA nruab nrab. Lawv kuj tau tshwm sim ntau yam kab mob hauv tib neeg. Qhov sib txawv tseem ceeb ntawm adenovirus thiab retrovirus yog nyob ntawm qhov muaj thiab tsis muaj lub hnab ntawv. Adenovirus yog ib hom kab mob uas tsis muaj lub hnab ntawv thaum cov kab mob retroviruses yog cov kab mob hauv lub hnab.
Adenovirus yog dab tsi?
Adenoviruses yog cov pab pawg kab mob uas tsim los ntawm cov kab mob uas tsis yog lub hnab ntim khoom. Lawv yog cov kab mob ntau heev rau tib neeg, thiab qee qhov kuj tuaj yeem kis rau tsiaj. Tsev neeg adenovirus tau muab faib ua ob hom tseem ceeb xws li; Mastadenoviruses thiab Aviadenoviruses. Mastadenovirus kis rau tib neeg thiab tsiaj txhu thaum Aviadenovirus kis tau rau noog.
Tus yam ntxwv ntawm tus yam ntxwv ntawm tus kabmob adenovirus yog qhov tsis muaj lub hnab ntawv viral. Lawv feem ntau yog icosahedral nyob rau hauv cov duab thiab muaj ob-stranded DNA ua lawv cov khoom siv caj ces. Cov khoom siv noob caj noob ces yog embedded nyob rau hauv ib tug protein core. Lub plhaub icosahedral protein yog 70 - 100 nm inch thiab yog tsim los ntawm 252 cov txheej txheem capsomere proteins. Lub plhaub icosahedral tseem muaj cov protein me me ntxiv hu ua cov ntsiab lus me me polypeptide.
Kev sib faib lossis kev loj hlob ntawm tus kabmob adenovirus hauv tib neeg lub xovtooj yuav tshwm sim thaum nkag mus rau cov ntsiab lus ntawm cov kab mob caj ces rau hauv tib neeg lub cell. Tom qab nws txhaj tshuaj genetic khoom rau hauv lub cell, tus kab mob DNA yog transcribed nrog kev pab los ntawm tus tswv transcription mechanisms los ua ke cov adenoviral mRNA, ua raws li cov proteins tseeb. Thaum kawg, cov kab mob tshiab tau sib sau ua ke thiab tso tawm kom nws muaj peev xwm kis tau ntau lub hlwb.
Daim duab 01: Adenovirus
Kab mob tshwm sim los ntawm adenoviruses feem ntau cuam tshuam nrog cov kab mob ua pa thiab kab mob sib kis. Kev kis tus kab mob adenovirus tshwm sim los ntawm huab cua tee, thiab kev kuaj mob ntawm tus kab mob adenoviral yog nyob ntawm kev sim tshuaj tiv thaiv kab mob thiab kab mob molecular. Cov tsos mob xws li ua npaws thiab lwm yam kab mob thib ob kuj tseem tuaj yeem pom nyob rau hauv cov xwm txheej tiv thaiv kab mob
Retrovirus yog dab tsi?
Retroviruses yog ib tsev neeg ntawm cov kab mob uas tau muab faib ua cov kab mob hauv lub hnab. Ib qho ntawm feem ntau cov kab mob retroviruses kis rau tib neeg thoob ntiaj teb yog Human Immunodeficiency Virus (HIV) uas ua rau Acquired Immuno deficiency syndrome (AIDS).
Tus kab mob no muaj RNA genome uas yog ib qho kev tso tseg thiab kev nkag siab zoo. Retroviruses muaj cov noob uas encode rau RNA nyob ntawm DNA polymerase hu ua Reverse transcriptase enzyme. Reverse transcriptase enzyme yuav transcript RNA rov qab mus rau DNA (lub npe hu ua complementary DNA (cDNA)). Lub cDNA synthesized los ntawm cov noob caj noob ces nyob rau hauv lub host cell yuav pib qhov sib npaug ntawm cov kab mob. Cov kab mob retroviruses muaj lub hnab ntawv tseem ceeb nrog rau lub capsid thiab cov tub ntxhais sab hauv uas yog tsev lub genome ntawm cov particle.
Retroviruses tuaj yeem kis tau los ntawm kev sib cuag ncaj qha ntawm ob tus tib neeg lossis ntawm ob tus tsiaj. Muaj peb tsev neeg retroviruses xws li; Oncovirus, Lentivirus thiab Spumavirus. Cov kab mob oncoviruses yog cov kab mob uas ua rau muaj mob qog noj ntshav. Lentiviruses yog cov kab mob uas ua rau muaj qhov pib kis kab mob tuag taus thaum Spumavirus muaj npe yog li nws muaj cov yam ntxwv spikes tawg tawm ntawm lub hnab ntawv.
Daim duab 02: Retrovirus
Cov kab mob cuam tshuam nrog kev kis tus kab mob rov qab muaj xws li feline leukemia lossis sarcoma, caprine mob caj dab encephalitis, tib neeg laus cell leukemia thiab lwm yam.
Dab tsi zoo sib xws ntawm Adenovirus thiab Retrovirus?
- Ob hom adenovirus thiab retrovirus muaj peev xwm kis tau tib neeg tus tswv.
- Ob qho tib si adenovirus thiab retrovirus hom yog obligate parasites.
- Ob qho tib si adenovirus thiab retrovirus hom muaj nyob txhua qhov chaw.
- Ob qho tib si adenovirus thiab retrovirus hom raug suav tias yog tus kab mob virulent.
Qhov txawv ntawm Adenovirus thiab Retrovirus yog dab tsi?

Summary - Adenovirus vs Retrovirus
Viruses yog cov kab mob sib kis uas kis tau tus tswv tsev tshwj xeeb thiab yog li hu ua tus kab mob yuav tsum tau ua. Tawm ntawm ntau qhov kev faib tawm ntawm cov kab mob, lawv kuj tau categorized li Adenoviruses thiab Retroviruses, raws li muaj lossis tsis muaj lub hnab ntawv. Yog li, tsev neeg tus kab mob uas muaj ib lub hnab ntawv yog hu ua retrovirus, hos cov kab mob uas tsis muaj lub hnab ntawv yog hu ua adenovirus. Adenovirus muaj ob-kab DNA genome whereas cov retroviruses uas muaj HIV muaj ib leeg-stranded RNA genome. Yog li ntawd, cov kab mob retroviruses tau thim rov qab los tsim cDNA nrog kev pab los ntawm enzyme reverse transcriptase. Qhov no yog qhov txawv ntawm adenovirus thiab retrovirus.
