Kab mob Ko taw thiab qhov ncauj

(1) Cov xwm txheej kis mob

Cov kab mob ko taw thiab qhov ncauj thoob ntiaj teb no feem ntau tshwm sim hauv Africa, Middle East, Asia thiab thaj chaw ntawm South America. Ntawm 7 serotypes ntawm FMDV, hom O thiab hom A yog qhov muaj ntau tshaj plaws; Hom I, II thiab III ntawm South Africa feem ntau muaj nyob rau hauv cov teb chaws African; Cov neeg Esxias hom I feem ntau muaj nyob rau hauv Middle East thiab South Asia; Hom C tsis tau tshaj tawm txij li nws tau tshwm sim hauv Brazil thiab Kenya xyoo 2004. Hauv 2021, qhov xwm txheej kis mob ntawm ko taw thiab qhov ncauj nyob rau sab hnub tuaj Asia tseem nyuaj. Cambodia, Malaysia, Myanmar, Thaib, Nyab Laj thiab lwm lub tebchaws muaj kev sib kis, thiab cov kab mob uas ua rau muaj kev sib kis nyuaj. Qhov kev hem thawj rau kev tiv thaiv thiab tswj cov kab mob ko taw thiab qhov ncauj hauv Suav teb tseem muaj.

Tam sim no, qhov xwm txheej ntawm tus kab mob ko taw thiab qhov ncauj hauv Suav teb feem ntau ruaj khov, thiab kab mob ko taw thiab qhov ncauj hom I hauv Asia tseem tsis muaj kev sib kis. Tsis muaj tus kab mob ko taw thiab qhov ncauj hom A kis nyob rau hauv peb lub xyoos tsis ntev los no, thiab yuav muaj peb tus kab mob ko taw thiab qhov ncauj qhov ncauj nyob rau xyoo 2021. Raws li kev soj ntsuam, cov kab mob FMD tam sim no nyob hauv Suav teb tseem nyuaj. Hom O FMD hom muaj xws li Ind-2001e, Mya-98 thiab CATHAY, thaum Hom A yog Hiav Txwv-97. Hom AA/Sea-97 tus kab mob txawv teb chaws yuav raug kuaj pom nyob rau thaj tsam ciam teb xyoo 2021.

Cov tshuaj tiv thaiv kab mob ko taw thiab qhov ncauj hauv Suav teb muaj txiaj ntsig zoo tiv thaiv kab mob sib kis hauv tsev, thiab cov ntsiab lus muaj feem cuam tshuam txog kev sib kis feem ntau muaj nyob rau hauv cov kev sib txuas thiab cov chaw uas muaj kev tiv thaiv tsis muaj zog. Raws li kev soj ntsuam cov ntaub ntawv, nws tau kwv yees tias FMD kev kis mob hauv Suav teb tseem yuav raug tswj hwm los ntawm FMD hom O hauv xyoo 2022, thiab kev sib kis ntawm ntau hom FMD hom O yuav txuas ntxiv mus, uas tsis txwv qhov muaj peev xwm tshwm sim ntawm FMD hom A; Txoj kev pheej hmoo ntawm cov kab mob txawv teb chaws tau nkag mus rau hauv Suav teb tseem muaj.

(2) Kev xaiv tshuaj tiv thaiv

Xaiv cov tshuaj tiv thaiv uas phim cov antigenicity ntawm cov kab mob sib kis hauv zos, thiab cov ntaub ntawv tshuaj tiv thaiv tuaj yeem nug hauv "National Veterinary Drug Basic Information Query" platform "Veterinary Drug Product Approval Number Data" ntawm Tuam Tshoj Veterinary Drug Information Network.

(3) Cov txheej txheem txhaj tshuaj tau pom zoo

1. Nplai teb

Lub hnub nyoog ntawm kev txhaj tshuaj thawj zaug ntawm cov tsiaj hluas tau txiav txim siab los ntawm kev coj mus rau hauv cov xwm txheej xws li kev tiv thaiv niam txiv thiab qib niam cov tshuaj tiv thaiv kab mob ntawm cov tsiaj hluas. Piv txwv li, raws li qhov sib txawv ntawm lub sijhawm txhaj tshuaj ntawm cov poj niam tsiaj thiab cov tshuaj tiv thaiv niam txiv, piglets tuaj yeem xaiv txhaj tshuaj tiv thaiv thaum muaj hnub nyoog 28-60 hnub, cov menyuam yaj tuaj yeem txhaj tshuaj tiv thaiv thaum muaj hnub nyoog 28-35 hnub, thiab cov nyuj tuaj yeem txhaj tshuaj tiv thaiv thaum muaj hnub nyoog 90 hnub. Tom qab kev txhaj tshuaj thawj zaug ntawm tag nrho cov tsiaj yug tshiab, kev txhaj tshuaj tiv thaiv kab mob yuav tsum tau ua ib zaug txhua 1 lub hlis, thiab tom qab ntawd txhua 4 mus rau 6 lub hlis.

2. Cov tsev neeg saib xyuas tsis tu ncua

Nyob rau lub caij nplooj ntoo hlav thiab lub caij nplooj zeeg, tag nrho cov tsiaj txhu uas raug mob hauv tsev yuav raug txhaj tshuaj ib zaug, thiab lawv yuav raug them nyiaj tsis tu ncua txhua lub hlis. Qhov twg muaj kev tso cai, kev txhaj tshuaj tiv thaiv tuaj yeem ua tau raws li cov txheej txheem txhaj tshuaj ntawm thaj chaw loj.

3. Kev txhaj tshuaj tiv thaiv xwm txheej ceev

Thaum muaj xwm txheej kis tau tshwm sim, cov tsiaj txhu uas raug mob hauv cheeb tsam kis mob thiab thaj chaw raug hem yuav tsum tau txhaj tshuaj tiv thaiv xwm txheej ceev. Thaum thaj chaw ciam teb raug hem los ntawm cov xwm txheej txawv teb chaws, suav nrog cov txiaj ntsig ntawm kev pheej hmoo, cov tsiaj txhu uas muaj kev pheej hmoo siab ntawm ko taw thiab qhov ncauj yuav tau txhaj tshuaj tiv thaiv xwm txheej ceev. Cov tsiaj txhu uas tau txhaj tshuaj nyob rau lub hli tas los yuav tsis tau txhaj tshuaj tiv thaiv xwm txheej ceev.

(4) Kev saib xyuas kev tiv thaiv kab mob

1. Kev sim

Cov txheej txheem tau teev tseg hauv GB / T 18935-2018 Diagnostic Techniques for Foot and Mouth Disease yog siv los kuaj cov tshuaj tiv thaiv kab mob. Rau cov uas tau txhaj tshuaj tiv thaiv tsis muaj zog, cov kua theem thaiv ELISA thiab cov theem sib tw ELISA tau siv los kuaj xyuas cov tshuaj tiv thaiv kab mob; Rau cov tshuaj tiv thaiv nrog cov tshuaj tiv thaiv peptide hluavtaws, VP1 cov qauv protein ELISA tau siv los kuaj xyuas cov tshuaj tiv thaiv kab mob.

2. Kev ntsuam xyuas kev tiv thaiv kab mob

Tom qab 28 hnub ntawm kev txhaj tshuaj ntawm npua thiab 21 hnub ntawm kev txhaj tshuaj ntawm lwm cov tsiaj hauv tsev, cov tshuaj tiv thaiv kab mob yuav tsum ua raws li cov hauv qab no los txiav txim siab tias tus neeg tiv thaiv tau tsim nyog:

Ua kua theem thaiv ELISA: tshuaj tiv thaiv kab mob titer ntawm cov tsiaj ruminant xws li nyuj thiab yaj ≥ 2^7, thiab npua antibody titer ≥ 2^6.

Khoom theem sib tw ELISA: antibody titer ≥ 2 ^ 6.

vP1 structural protein antibody ELISA: zoo raws li txoj kev los yog cov lus qhia reagent.

Yog tias tus naj npawb ntawm cov neeg tsim nyog suav tsis pub tsawg dua 70% ntawm tag nrho cov kab mob tiv thaiv kab mob, cov pab pawg tiv thaiv yuav raug txiav txim tias tsim nyog.
