----IziKhokelo zeSizwe zobuGcisa kuGonyo lweZilwanyana ngo-2022
Ukuze wenze umsebenzi omhle ekugonyweni kwizifo zezilwanyana, iZiko loKhuseleko lweSifo kunye noLawulo lweZilwanyana laseChina laqulunqa ngokukodwa iziKhokelo zeSizwe zezobuGcisa zokugonywa kwi-Animal Epidemics ngo-2022 ngokuhambelana neemfuno zeSikhokelo sokuGunyaniswa kweZilwanyana zeSizwe (i-National Animal Epidemics). 2022-2025).
Isifo sonyawo kunye nomlomo
(1) Imeko yobhubhane
Isifo sonyawo kunye nomlomo kwihlabathi sixhaphake kakhulu e-Afrika, kuMbindi Mpuma, e-Asia nakwiindawo ezithile zoMzantsi Melika. Phakathi kwe-7 serotypes ye-FMDV, uhlobo lwe-O kunye nohlobo lwe-A luxhaphake kakhulu; Uhlobo I, II kunye ne-III zoMzantsi Afrika zixhaphake kakhulu kwilizwekazi lase-Afrika; Uhlobo lwaseAsia I luxhaphake kakhulu kuMbindi Mpuma naseMzantsi Asia; Uhlobo C aluzange luxelwe ukususela ekuqhambukeni kwayo eBrazil naseKenya ngo-2004. Ngo-2021, imeko yobhubhane yesifo sonyawo kunye nomlomo kwi-Southeast Asia isenzima. IKhambodiya, iMalaysia, iMyanmar, iThailand, iVietnam kunye namanye amazwe onke anoqhambuko, kwaye iingxaki ezibangela lo bhubhani zintsonkothile. Usongelo kuthintelo nolawulo lwesifo sonyawo nomlomo eTshayina sisaqhubeka sikhona.
Okwangoku, imeko yobhubhani wesifo sonyawo nomlomo eTshayina izinzile ngokubanzi, kwaye isifo samanqina nomlomo I eAsia sisahleli singenasifo. Akuzange kubekho ubhubhane lwesifo sonyawo kunye nomlomo kwiminyaka emithathu yakutshanje, kwaye kuya kubakho izifo ezintathu zesifo sonyawo kunye nomlomo we-O ngo-2021. Ngokwemeko yokubeka iliso, iintsholongwane ze-FMD zangoku e-China zisekho. entsonkothileyo. Uhlobo lwe-O lwe-FMD lubandakanya i-Ind-2001e, i-Mya-98 kunye ne-CATHAY, ngelixa i-Type A i-Sea-97. Uhlobo lwe-AA/Sea-97 intsholongwane yesebe yaphesheya iya kubhaqwa kwiindawo zemida ngo-2021.
Isitofu sokugonya isifo sonyawo kunye nomlomo e-China siyasebenza ngokuchasene neentlobo zendyikityha yasekhaya, kwaye iindawo zomngcipheko wobhubhane zikho ikakhulu kumakhonkco kunye neendawo ezinokhuselo olubuthathaka. Ngokusekwe kwidatha yokubeka iliso, kuqikelelwa ukuba ubhubhani we-FMD e-China useza kulawulwa yi-FMD uhlobo lwe-O ngo-2022, kwaye ubhubhani ngaxeshanye weentlobo ezininzi ze-FMD uhlobo lwe-O luya kuqhubeka, olungakhuphi amathuba okuba kwenzeke indawo. yohlobo lwe-FMD A; Umngcipheko wokungeniswa kweentlobo zangaphandle eTshayina usekho.
(2) UKhetho lwesitofu
Khetha izitofu ezihambelana ne-antigenicity yeentlobo zendyikityha yendawo, kunye nolwazi lwemveliso yokugonya lunokubuzwa kwi-"National Veterinary Drug Basic Query Query" iqonga "Idatha yeMveliso yeMveliso yeMfuyo yeMfuyo" ye-China Veterinary Drug Information Network.
(3) Iinkqubo eziCetyisiweyo zoGonyo
1. Indawo yesikali
Ubudala bogonyo lokuqala lwezilwanyana eziselula bumiselwe ngokuthathela ingqalelo izinto ezifana nokugonywa komama kunye nenqanaba le-antibody lomama kwizilwanyana ezincinci. Umzekelo, ngokomahluko kumaxesha okugonywa kwezilwanyana ezizimazi kunye nezithinteli-zifo zamanina, amantshontsho eehagu anokukhetha ukugonywa xa eneentsuku ezingama-28-60, amatakane anokugonywa xa eneentsuku ezingama-28-35 ubudala, kwaye amathole angagonywa. kwiminyaka engama-90 ubudala. Emva kokugonywa kokuqala kwayo yonke imfuyo esanda kuzalwa, ugonyo lwe-booster luya kwenziwa kanye ngenyanga enye, kwaye emva kweenyanga ezi-4 ukuya kwezi-6.
2. Amakhaya okhathalelo lwethutyana
Entwasahlobo nasekwindla, zonke izilwanyana zasekhaya ezisesichengeni ziya kugonywa kube kanye, kwaye ziya kuhlawulwa rhoqo ngenyanga. Apho iimeko zivumayo, ugonyo lunokwenziwa ngokwenkqubo yogonyo kwibala elikhulu.
3. Ugonyo oluNgxamisekileyo
Xa imeko yobhubhane isenzeka, imfuyo esesichengeni kwindawo yobhubhane kunye nendawo esesichengeni iya kugonywa ngokungxamisekileyo. Xa ummandla womda usongelwa yimeko yendyikityha yaphesheya kweelwandle, idityaniswe neziphumo zovavanyo lomngcipheko, imfuyo esengozini kwindawo ephezulu yesifo sonyawo nomlomo iya kugonywa ngokungxamisekileyo. Imfuyo egonyiweyo kwinyanga ephelileyo ayinakugonywa ngokungxamisekileyo.
(4) Ukujongwa kwempembelelo yamajoni omzimba
1. Indlela yokuvavanya
Indlela echazwe kwi-GB / T 18935-2018 iTechniques Diagnostic for Foot and Mouth Disease yayisetyenziselwa ukufumanisa i-antibody. Kwabo bagonywe ngesitofu sokugonya esingasebenziyo, isigaba solwelo sokuthintela i-ELISA kunye nesigaba esiqinileyo sokhuphiswano lwe-ELISA sasetyenziselwa ukufumanisa i-antibody; Kwabo bagonywe ngesitofu sokugonya se-peptide yokwenziwa, i-VP1 yeprotein yesakhiwo i-ELISA yasetyenziswa ukufumanisa i-antibody.
2. Uvandlakanyo lwempembelelo yamajoni omzimba
Emva kweentsuku ezingama-28 zokugonywa kweehagu kunye neentsuku ezingama-21 zokugonywa kwezinye izilwanyana zasekhaya, i-antibody titer iyakuhlangabezana nale ndlela ilandelayo yokumisela ukuba ukhuselo lomzimba lufanelekile:
Uthintelo lwesigaba solwelo i-ELISA: i-antibody titer yezilwanyana ezetyisayo njengeenkomo neegusha ≥ 2 ^ 7, kunye ne-pig antibody titer ≥ 2 ^ 6.
Isigaba esiqinileyo sokhuphiswano i-ELISA: i-antibody titer ≥ 2 ^ 6.
vP1 iprotein yesakhiwo se-antibody ELISA: ilungile ngokwendlela okanye imiyalelo ye-reagent.
Ukuba inani labantu abaqeqeshiweyo libalelwa ngaphantsi kwe-70% yenani lilonke lamaqela omzimba, ukhuselo lweqela luya kumiselwa njengolufanelekileyo.
