Mwamsangakuzindikira kwa African swine fever virus

"Tapeza mzere wa selo womwe ungagwiritsidwe ntchito kudzipatula ndi kuzindikira kachilombo kamene kamakhalapo," anatero wasayansi wa ARS Dr. Douglas Gladue."Ichi ndi gawo lalikulu komanso gawo lalikulu kwambiri pakuzindikiritsa kachilombo ka African swine fever."
Pakali pano palibe katemera wa ASF, ndipo kuwongolera miliri nthawi zambiri kumadalira kudzipatula ndi kuchotsedwa kwa nyama zomwe zili ndi kachilombo kapena zowonekera.Mpaka pano, kuzindikira kogwira mtima kwa kachilombo ka ASF kunafuna kusonkhanitsa maselo a magazi kuchokera ku nkhumba zamoyo zomwe zimayesedwa kuti ziyesedwe, popeza maselo angagwiritsidwe ntchito kamodzi kokha.Mizere yatsopano yama cell imatha kubwerezedwa mosalekeza ndikuwumitsidwa kuti igwiritsidwe ntchito mtsogolo, kuchepetsa kuchuluka kwa nyama zomwe zikufunika.
Mzere watsopano wa cell ukhoza kugwiritsidwanso ntchito m'ma laboratories ozindikira zanyama, omwe mwachizolowezi alibe mwayi wopeza ma cell amagazi a nkhumba ofunikira kuti azindikire kachilombo ka ASF.
Malinga ndi kafukufukuyu, matenda a ASF mu zitsanzo zachipatala (makamaka magazi athunthu) adachitidwa pogwiritsa ntchito nthawi yeniyeni ya polymerase chain reaction (RT-PCR), kuyesa kwa maselo omwe amatha kuzindikira gawo laling'ono la tizilombo toyambitsa matenda koma sangazindikire matenda opatsirana. kachilombo..Kudzipatula kwa ma virus ndikofunikira kuti mutsimikizire matenda okhudzidwa ndi kusanthula kotsatira, monga kutsatizana kwa matupi athu onse.Panopa, HIV kudzipatula ndi zotheka ntchito chachikulu porcine macrophages, amene kawirikawiri kupezeka ambiri dera Chowona Zanyama zasayansi zasayansi.Kupanga ma macrophages oyambilira a nkhumba kumawononga nthawi komanso kugwira ntchito molimbika chifukwa chosowa kusonkhanitsa ma cell amagazi a nkhumba kapena kudzipatula ku maselo am'mapapo.Kafukufuku wam'mbuyomu awonetsa kuti kachilombo ka ASF kamafanananso m'maselo okhazikika kachilomboka kakalowa mu cell inayake, nthawi zambiri pakadutsa njira zingapo.Mpaka pano, ma cell okhwima omwe amapezeka pamalonda sanawonetsedwe kuti ndi oyenera kudzipatula kwa ma virus a ASF pogwiritsa ntchito zitsanzo zakumunda.
Mu phunziro ili, ofufuzawo adapeza mzere wa cell womwe ungathe kuthandizira kuzindikiraASFVpazitsanzo zakumunda zokhala ndi chidwi cha TCID50 chofananira ndi macrophages oyambira a nkhumba.Kuyang'ana mosamalitsa kwa ma cell omwe amagulitsidwa kwapangitsa kuti adziwike ma cell a nyani obiriwira aku Africa a MA-104 ngati wolowa m'malo mwa ma macrophages oyambilira a nkhumba za ASF.
Pakhala posachedwapa kuphulika kwa kachilombo ka ASF kunja kwa dziko la Africa kuyambira pamene inayamba ku Republic of Georgia mu 2007. Matendawa afalikira ku China ndi mayiko a Southeast Asia, kuphatikizapo Mongolia, Vietnam, Cameroon, North ndi South Korea, Laos. , Myanmar, Philippines, Timor-Leste, Indonesia, Papua New Guinea ndi India.Kuphulika kwaposachedwa kwa zovuta za "Georgia" ndizofala kwambiri komanso zimapha nkhumba zapakhomo, zomwe zimafa mpaka 100%.Ngakhale kachilomboka kulibe ku United States, msika wa nkhumba ku US ukhoza kuwonongeka kwambiri pazachuma pakabuka.
