PRRS yog ib yam kab mob sib kis tau zoo heev uas tshwm sim los ntawm tus kab mob porcine reproductive thiab ua pa kab mob, uas yog kub taub hau, anorexia, lig nchuav menyuam, yug ntxov ntxov, tseem yug me nyuam, tsis muaj zog thiab mummified fetuses, thiab ua tsis taus pa nyob rau hauv npua ntawm txhua lub hnub nyoog (tshwj xeeb tshaj yog cov menyuam yaus npua).
PRRSV (Nidovirales) Arteritis viridae Arteritis tus kab mob genus cov tswv cuab, raws li cov antigenicity, genome thiab pathogenicity ntawm tus kab mob, PRRSV tuaj yeem muab faib ua 2 hom, uas yog European hom (LV hom raws li tus neeg sawv cev hom) thiab American hom (ATCC-VR2332 hom raws li tus neeg sawv cev ntawm 7% homology), homology 8% homology.
ELISA yog siv rau kev kuaj tshuaj tiv thaiv kab mob rau PRRS.Cov txiaj ntsig tshuaj tiv thaiv kab mob yog niaj hnub qhia raws li S / P qhov tseem ceeb.Qhov kev sawv cev no yog xam los ntawm cov nqi tseem ceeb (tswj qhov tseem ceeb).Nws yog tsim nyog sau tseg tias rau kev kuaj pom ntawm pob ntseg pob ntseg, tib qho qauv, cov khoom sib txawv, cov kev xeem sib txawv, cov neeg ua haujlwm sib txawv yuav txawv.Yog li ntawd, cov txiaj ntsig kev xeem yuav tsum tau muab tshuaj ntsuam xyuas thiab txiav txim kom muaj nuj nqis nrog rau qhov tseeb ntawm cov khoom lag luam ntawm npua teb.
