Qhov sib txawv tseem ceeb ntawm orthomyxovirus thiab paramyxovirus yog tias orthomyxovirus muaj segmented RNA genome thaum paramyxovirus RNA genome tsis segmented.
Myxoviruses yog tus kab mob khaub thuas. Cov kab mob no qhia affinity rau mucins. Muaj ob pawg ua orthomyxovirus thiab paramyxovirus. Orthomyxovisu thiab paramyxovirus yog ob pawg ntawm cov kab mob uas muaj qhov tsis zoo-xav ib leeg-kab RNA genomes. Lawv yog cov kab mob helical-zoo li tus kab mob uas tau ntim. Orthomyxovirus muaj ib qho RNA genome segmented rau yim daim, thaum paramyxovirus muaj ib tug tsis-segmented genome.
Orthomyxovirus yog dab tsi?
Orthomyxoviru yog ib tus kab mob me me uas muaj qhov tsis zoo rau ib leeg-tso genome uas muaj 8 daim RNA. Yog li ntawd, lub genome ntawm orthomyxovirus yog segmented. Nws yog tsim los ntawm helical nucleocapsid. Tsis tas li ntawd, nws yog ib lub hnab ntim cov kab mob uas muaj lipoprotein sab nraud lub hnab ntawv. Influenza A, B thiab C belongs rau orthomyxoviruses. Orthomyxoviral particles muaj qhov loj ntawm 80 mus rau 120 nm inch. Cov kab mob no kuj muaj endogenous RNA polymerase. Lawv ua rau muaj mob nyob rau hauv qis thiab sab sauv ib ntsuj av. Tus kab mob no kis tau los ntawm ib tus neeg mus rau lwm tus los ntawm aerosols ntawm cov pa ua pa.
Daim duab 01: Orthomyxovirus
Paramyxovirus yog dab tsi?
Paramyxovirus yog ib tus kab mob loj nrog qhov tsis zoo-xav ib leeg-stranded RNA genome. Nws muaj RNA-directed RNA polymerase. Paramyxovirus yog tsim los ntawm helical nucleocapsid. Tus kab mob genome tsis segmented hauv paramyxovirus. Qhov loj ntawm paramyxovirus yog li ntawm 150 nm txog 300 nm. Nws yog ib lub hnab ntim cov kab mob nrog cov kab mob sib txuas nrog cov protein thiab fusion protein. Paramyxovirus yog replicated nyob rau hauv lub host cell cytoplasm.
Daim duab 02: Paramyxovirus
Paramyxoviruses yog lub luag haujlwm rau cov kab mob ua pa hnyav. Lawv kis tau los ntawm huab cua los yog kev sib cuag ncaj qha. Cov kab mob paramyxoviruses yog cov kab mob xws li mumps, qhua pias (rubeola), RSV (tus kab mob ua pa syncytial), kab mob Newcastle, thiab parainfluenza.
Dab tsi zoo sib xws ntawm Orthomyxovirus thiab Paramyxovirus?
- Orthomyxovirus thiab Paramyxovirus yog RNA cov kab mob uas tau ntim.
- Lawv cov protein capsid yog helical hauv cov duab.
- Kev sib npaug ntawm txhua tus paramyxoviruses zoo ib yam li ntawm orthomyxoviruses.
- Lawv kis ntawm aerosols.
Qhov txawv ntawm Orthomyxovirus thiab Paramyxovirus yog dab tsi?
Qhov sib txawv tseem ceeb ntawm orthomyxovirus thiab paramyxovirus yog qhov genome ntawm orthomyxovirus yog segmented thaum lub genome ntawm paramyxovirus tsis yog. Orthomyxovirus yog ib hom kab mob RNA uas muaj segmented genome. Nws muaj yim ntu RNA. Lub caij no, tus kab mob paramyxovirus kuj yog ib tus kab mob RNA ib leeg xwb tab sis nrog cov kab mob uas tsis yog kab RNA genome.
Ntxiv mus, cov kab mob orthomyxoviruses me me, thiab lawv qhov ntau thiab tsawg ntawm 80 nm txog 120 nm. Tab sis, paramyxoviruses loj, thiab lawv qhov ntau thiab tsawg ntawm 150 nm txog 300 nm. Tsis tas li ntawd, tus kab mob orthomyxovirus tuaj yeem ua rau mob khaub thuas hom A, B thiab C thaum paramyxovirus tuaj yeem ua rau mob qog, qhua pias, kab mob parainfluenza 1-4 thiab kab mob RSV. Tsis tas li ntawd, hais txog qhov chaw ntawm kev sib txuas ntawm ribonucleoprotein, hauv orthomyxoviruses, nws yog nucleus thaum nyob rau hauv paramyxoviruses, nws yog cytoplasm.
Cov duab hauv qab no piv cov kab mob thiab tabulates ib sab ntawm qhov sib txawv ntawm orthomyxovirus thiab paramyxovirus.
Summary - Orthomyxovirus vs Paramyxovirus
Orthomyxovirus thiab paramyxovirus yog ob hom kab mob RNA ib leeg uas ua rau muaj kab mob ua pa. Lawv yog cov kab mob hauv lub hnab uas yog tsim los ntawm helical nucleocapsids. Orthomyxovirus genome yog segmented thiab muaj 8 daim RNA. Paramyxovirus genome tsis segmented. Ntxiv mus, orthomyxovirus me me thaum paramyxovirus loj. Tsis tas li ntawd, orthomyxovirus yog replicated nyob rau hauv lub nucleus thaum paramyxovirus replicated nyob rau hauv lub cytoplasm. Yog li, qhov no qhia txog qhov sib txawv ntawm orthomyxovirus thiab paramyxovirus.
