Cov kab mob kis tau ua rau kev hem thawj tsis tas rau cov tsiaj nws tus kab mob, tab sis kuj rau tib neeg.
Piv txwv, qhov chaw ntawm Salmonella, pom nyob rau hauv cov zaub mov ntawm kev lag luam thiab hauv khw muag khoom, feem ntau yog cov nqaij ntawm cov nqaij qaib hlob muag.
Yog li, nws yog qhov yuav tsum tau paub cov tsos mob tseem ceeb, kev tiv thaiv kab mob thiab kev kho mob xws li ib qho kev kis kab mob txaus ntshai li tus kab mob rub qaub-typhoid.
Pullorosis - (typhoid, bacillary dysentery, white bacillary diarrhea, white bacillary diarrhea) yog ib yam kabmob phem uas muaj kabmob ua rau cov menyuam yaus thiab mob ntev, asymptomatic rau cov laus.
Ruboroid yog dab tsi?
Kab mob prone mus rau nqaij qaib: chickens, turkeys, ducks (tshwj xeeb tshaj yog cov tub ntxhais hluas), thiab cov noog qus: quail, pheasants, guinea fowls. Cov kab mob loj tshaj plaws ntawm tus kab mob no tau pom nyob rau hauv cov qaib txij thaum yug mus txog 2 lub lim tiam ntawm lub hnub nyoog.
Pulloz-typhus tau pom thawj zaug hauv Tebchaws Meskas (Connecticut) xyoo 1900 los ntawm Retger. Txij lub sij hawm, tus kab mob no tau ua thoob plaws hauv Tebchaws Meskas thiab lwm lub tebchaws.
Hauv USSR, tus kab mob tau tshwm sim hauv 1924 los ntawm tus kws qhia ntawv Ushakov. Pulloz-typhus tau nkag rau hauv kev sib koom nrog cov qaib txawv, yug qaib qaib thiab qaib cov txwv, lawv cov qe.
Tus mob yog tam sim no sau npe nyob rau hauv ntau poultry liaj teb thiab industrial factories rau cov khoom noj thiab khoom ntawm nqaij qaib nqaij, qaib qe rau kev lag luam thiab khw.
Kev faib khoom thiab vectors
Tus kab mob no raug kaw hauv txhua lub teb chaws.
Cov noob neeg ntawm tus kab mob thaum lub sij hawm tsim cov qe nyob rau hauv ovaries ntawm cov noog mob, cov qaib yug los rau cov tib neeg muaj tus kab mob zoo rau lawv cov xeeb ntxwv. Tus kab mob no yog ua los ntawm qhov chaw nyob ruaj khov.
Kab mob kis tau los ntawm cov kab mob kis tau los ntawm cov qe thiab cov kua dej, cov dej, khoom noj, cov noog mob, cov qe unfertilized, shells, khoom rau kev tu cov noog mob, thiab kev sib kis kuj yog nce los ntawm roosters.
Cov vectors yog me me nas, sparrows, starlings, tits, bullfinches, daws thiab lwm yam tsiaj txhu pub dawb.
Degree ntawm kev txaus ntshai thiab kev puas tsuaj
Yog tias tsis muaj kev ntsuas zoo los tua cov kab mob kis tau tus kab mob kis tau tus kab mob ntswg, tus kab mob cuam tshuam rau tag nrho cov noog, qhov tshwm sim ntawm cov me nyuam hluas tuaj ncav 70%, rau lawv tus kab mob kis tau yog qhov feem ntau txaus ntshai.
Cov txiaj ntsim kev tuag ntawm cov nqaij qaib yog 80%yog hais tias lub sij hawm tsis noj tshuaj thiab tiv thaiv kev ntsuas.
Salmonella, uas nkag mus rau hauv tib neeg lub cev los ntawm cov nqaij ntawm cov mob muaj mob, ua rau mob plab hnyuv, ua rau kub taub hau, ntuav, raws plab, mob plab, kub cev, thiab kev qaug cawv.
Cov neeg mob nrog tus kab mob salmonellosis yog mus pw hauv tsev kho mob.
Pathogens
Tus kab mob ua rau Salmonellapullorum-Gallinarum (Salmonella pullorum-gallinarum) - cov kab mob luv luv (1-2 microns ntev thiab 0.3-0.8 microns tuab) ruaj ruaj, lawv tsis ua cov tshuaj ntsiav los yog cov kab mob.
Nyob hauv khib nyiab ntawm cov noog mob, cov kab mob ua rau 100 hnub, nyob rau hauv cov av - ntau tshaj 400 hnub, dej - mus txog 200 hnub, lawv tuaj yeem mob siab rau cov neeg mob ntawm lub cev (txog 40 hnub).
Cov kab mob nyob hauv tsev sov hauv tsev tsuas khaws cov khoom txheeb raws roj ntsha 7 xyoo, tab sis kub siab ua rau lawv. Yog li ntawm qhov kub ntawm 60 ° C, cov kab mob puas nyob hauv ib nrab ib teev, mus txog 100 ° C - hauv 1 feeb, thaum noj cov qe - hauv 8 feeb.
Naturally resistant Salmonella yog cov tshuaj tsis haum rau cov tshuaj tua kab mob, lawv raug puas los ntawm formaldehyde, tshuaj dawb, tshuaj carbonbolic acid.
Cov tsos mob hauv ntau hom kawm
Nyob rau hauv lub mob kawm ntawm tus kab mob nyob rau hauv cov noog yog pom:
- dawb quav;
- kev nyuaj siab;
- zawv plab;
- tsis muaj kev sib koom tes ntawm qhov taw;
- nervousness;
- coma;
- lethargy;
- fais fab tuag;
- glued fluff ze lub cloaca;
- qhov omission ntawm tis.
Cov tsos mob ntawm subacute chav kawm:
- plumage plumage pluag;
- boiler o ntawm ko taw pob yas qej;
- impaired digestion;
- ua tsis taus pa luv;
- kom siab rau (45 ° C).
Nws raug pom tias Firewall qaib los ntawm kev yug me nyuam heev nyob rau hauv cov tsos thiab sai sai nce nce phaus.Koj cov noog puas kis mob yooj yim dua? Ces theej nyeem: //selo.guru/ptitsa/kury/bolezni/k-virusnye/prostogonimoz.html.
Cov chav kawm ntev:
- kev loj hlob ruam;
- kev loj hlob ncua;
- peritonitis (biliary lossis fibrinous);
- salpingitis;
- hyperthermia;
- nqhis dej;
- tsis muaj qab los noj mov;
- tsis muaj zog
Qhov tsim kom ntev li ntawm 20 hnub. Lub peculiarity lies nyob rau hauv qhov tseeb hais tias cov noog uas tau raug kev txom nyem ib tug kab mob tau txais kev tiv thaiv thiab tsis muaj tus kab mob dua.
Diagnostics
Kev kuaj yog complex, yuav siv nyiaj rau txhua tus neeg mob, cov ntaub ntawv, tshuaj xyuas tag nrho cov duab saib mob, tag nrho cov kev hloov uas tshwm sim hauv lub cev ntawm cov neeg mob.
Tab sis qhov kawg kuaj yog ua raws li cov ntsiab lus ntawm bacteriological tshawb fawb, thaum tus kab lis kev cai ntawm pathogen yog cais nyob rau hauv nws daim ntawv dawb huv. Cov khoom ntawm txoj kev tshawb no yuav:
- lub cev tuag ntawm cov noog mob;
- nplooj siab;
- gallbladder;
- raum;
- lub plawv;
- spleen;
- ntshav;
- qe ntawm cov tsiaj muaj mob.
Rau kev tsim kab mob ntawm tus kab mob, kev siv tshuaj tua kab mob yog siv - cov ntshav-thiab-agglutination agglutination cov tshuaj tiv thaiv (CCRA) rau cov iav thiab cov ntshav-thiab-cov tshuaj tiv thaiv ntawm kev tiv thaiv hemagglutination nrog cov erythrocyte pullore antigen (CCRNA).
Kev Kho Mob thiab Kev Tiv Thaiv
Cov kev ntsuas yooj yim:
- hloov cov neeg mob thiab tsis muaj zog qaib rau kev tua tsiaj.
- cais ntawm cov tub ntxhais hluas ntawm tus kab mob.
- muab cov khoom noj kom zoo, sib thooj rau lawv lub hnub nyoog thiab cov tsos.
- kev kho mob thiab kev kho mob rau cov neeg muaj kev noj qab haus huv, uas yog siv txoj hauv kev, uas yog siv cov tshuaj yeeb dawb (sulfanilamide) ua ke nrog tshuaj tua kab mob (chlortetracycline hydrochloride, tetracycline, etc.). Qhov zoo tshaj plaws cov tshuaj yog furazolidone thiab furaltadone.
- txhua hli uas ua raws li cov ntshav-thiab-agglutination kom txog rau thaum muaj qhov tsis zoo.
- tswj kev tu cev ntawm thaj chaw uas cov noog thiab cov kab mob kaw, lawv niaj hnub ntxuav thiab tua kab mob.
- Carcases ntawm cov neeg nqa khoom muaj peev xwm siv tau hauv cov khoom noj khoom haus yog hais tias lawv tsis muaj cov cim qhia kev mob.
Txhawm rau tiv thaiv thiab tshem tawm kab mob, kev kho kev tiv thaiv kab mob thiab kev tiv thaiv kab mob, kev tshawb xyuas bacteriological thiab kev puas tsuaj ntawm cov neeg mob yuav tsum tau ua.
