Paramyxoviruses tau ntim virions (tus kab mob kab mob) sib txawv ntawm qhov loj ntawm 150 txog 200 nm (1 nm=10− 9meter) diam. Lub nucleocapsid, uas muaj lub plhaub protein (los yog capsid) thiab muaj cov kab mob nucleic acids, muaj helical symmetry.
Orthomyxovirus zoo li cas?
Tsev neeg Orthomyxoviridae
Virions yog spherical rau filamentous, txog 100 nm inch. Genomes yog segmented, ib leeg-stranded negative-strand RNA. Influenza A tus kab mob kis tau rau ntau hom tsiaj thiab noog, rov ua dua hauv cov pa thiab / lossis kab mob plab.
Tus kab mob twg yog los ntawm paramyxovirus?
Paramyxoviridae yog cov kab mob tseem ceeb, ua rau muaj hnub nyoog cov kab mob ntawm tib neeg thiab tsiaj txhu (qhua pias, rinderpest, canine distemper, mumps, respiratory syncytial virus (RSV), the Cov kab mob parainfluenza), thiab cov kab mob tshiab tau lees paub (Nipah, Hendra, morbilliviruses ntawm cov tsiaj hauv dej).
Muaj pes tsawg tus kab mob paramyxoviruses?
Muaj plaub hom ntawm HPIVs, hu ua HPIV-1, HPIV-2, HPIV-3 thiab HPIV-4. HPIV-1 thiab HPIV-2 tuaj yeem ua rau mob khaub thuas, nrog rau cov menyuam yaus. HPIV-3 yog txuam nrog bronchiolitis, bronchitis, thiab pneumonia.
Puas yog paramyxovirus segmented?
Paramyxovirus genomes yog non-segmented, negative-sense single-stranded RNA molecules. Ua kom tiav RNA sequences raupaub cov tswv cuab ntawm tsev neeg no yog kwv yees li 15200-15900 nucleotides ntev.
