Polio tus kab mob no sai heev, kua qaub -tiv thaiv, ruaj khov , cov ntaub so ntswg tshwj xeeb thiab muaj ib leeg-stranded, zoo RNA. Polio Tus kab mob no muaj peev xwm nyob hauv lub caj pas lossis txoj hnyuv ntawm tib neeg. Poliomyelitis yog tus kab mob sib kis tau zoo heev uas muaj peb hom kab mob, tus kab mob poliovirus 1 (PV1), PV2 thiab PV3.

Tom qab ntawd, ib tus tseem tuaj yeem nug, dab tsi ua rau picornavirus?

Kab mob sib kis picornaviruses tej zaum yuav asymptomatic los yog ua rau cov tsos mob xws li mob aseptic meningitis (kab mob kis tau yooj yim tshaj plaws ntawm CNS), mob hlwb, mob khaub thuas, mob ua npaws (mob tes-taw-thiab-qhov ncauj), kab mob sib kis, herpangina, myositis thiab myocarditis, thiab kab mob siab.

Ib yam nkaus, hom kab mob twg yog tus kab mob poliovirus? Poliovirus, tus neeg sawv cev ntawm tus mob polio (tseem hu ua poliomyelitis), yog hom kab mob ntawm cov tsiaj Enterovirus C, hauv tsev neeg ntawm Picornaviridae . Poliovirus yog tsim los ntawm ib qho RNA genome thiab protein capsid. Lub genome yog ib leeg-tso tseg txoj kev xav zoo RNA genome uas yog kwv yees li 7500 nucleotides ntev.

Tsis tas li, puas yog polio yog picornavirus?

Poliomyelitis (feem ntau hu ua " mob polio ") Yog kab mob sib kis los ntawm polioviruses 1, 2, thiab 3 hauv cov kab mob enterovirus ntawm picornaviridae viral tsev neeg. Los ntawm kev saib xyuas kev noj qab haus huv rau pej xeem, nws yog qhov tseem ceeb tshaj plaws ntawm enteroviruses.

Puas muaj tus kab mob polio muaj lub hnab ntawv?

Tib neeg enteroviruses Tus qauv ntawm tus kab mob poliovirus 1 tau txiav txim los ntawm X-ray crystallography nyob rau hauv 1985. Virions yog spherical nrog ib txoj kab uas hla ntawm 30 nm. RNA genome liab qab yog surrounded los ntawm cov proteins uas tsis muaj lipid lub hnab ntawv thiab nws cov kab mob yog tsis cuam tshuam los ntawm cov kuab tshuaj organic.
