kab mob liab los yog swine erysipelas yog ib yam kab mob ceeb toom uas tuaj yeem ua rau npua mob hnyav heev. Thawj daim duab uas los rau hauv siab txog tus kab mob no yog Txawm li cas los xij, qhov kev phem liab tuaj yeem ua rau muaj cov tsos mob ntau ntxiv, los ntawm cov kab mob septicemic mus rau mob caj dab lossis cov kab mob endocardial nrog kev tuag sai sai.
Kev tswj tus kab mob no yuav tsum yog los ntawm kev txhaj tshuaj tiv thaiv kab mob, vim cov kab mob no tiv taus ib puag ncig thiab kis tau zoo heev, yog li kev tshem tawm nyuaj heev. Mus nyeem ntawv tsab xov xwm no ntawm peb lub xaib kom paub ntau ntxiv txog erythema hauv npua, nws cov tsos mob thiab kev kho mob
Pab mob liab yog dab tsi?
Swine erythema is an infectious and highly contagious disease that affects pigs causing acute cutaneous and septic conditions, as well as chronic with arthritis, dermatitis thiab endocarditis. Lwm cov tsiaj uas tuaj yeem cuam tshuam tau yog npua qus, qaib ntxhw, yaj lossis ntses. Cov neeg mob kuj tuaj yeem cuam tshuam, vim qhov mob liab yog zoonosis, ua rau daim tawv nqaij hu ua Erypsela of Rosenbach.
Nov yog ib tug kab mob multifactorial, yog li ib puag ncig yam tseem ceeb koom nrog nws txoj kev loj hlob. Cov xwm txheej no yog:
- High kub.
- High humidity.
- Climate change.
- Pab npua.
- Phau Ntawv Hloov.
- Txoj kev mus los.
- Lwm yam kab mob (mycotoxins, PRRS, parasites…).
- Vaccination.
- Dab tsi kub nruab hnub thiab hmo ntuj.
Koj kuj yuav txaus siab rau lwm tsab xov xwm hais txog cov kab mob feem ntau ntawm Nyab Laj npua.
Dab tsi ua rau mob liab hauv npua?
Tus kab mob no tshwm sim los ntawm Erysipelothrix rhusiupathiae, ib tug kab mob nyob rau hauv daim ntawv ntawm ib tug bacillus, aerobic los yog facultative anaerobic, rhiab rau ib tug pH. hauv qab no 7, 5.
npua kis tau swine erypsela hauv quav, oronasal exudates, tso zis, thiab phev; thiab kis tau los ntawm qhov ncauj los ntawm kev noj zaub mov lossis dej uas muaj kab mob los ntawm kev sib cuag nrog tsiaj los yog matings. Npua raug mob ntau dua
Cov kab mob no tiv taus ntau heev nyob rau hauv ib puag ncig, nyob rau lub hlis nyob rau hauv cov chaw, nqaij thiab hmoov. Nws raug tshem tawm nrog quaternary disinfectants ntawm ammonium, dej qab zib, formaldehyde thiab glutaraldehydes.
Tsis tas li ntawd, nws nthuav tawm ob lub serovariants:
- Serovariant 1: virulent, ua rau septicemia.
- Serovariant 2: less virulent. Nws ua rau cov kab mob ntev thiab subacute.
Clinical forms of red disease in npua thiab lawv cov tsos mob
Lub sij hawm incubation yog luv, nrog ib tug siab tshaj 7 hnub. Tus kab mob no tuaj yeem ua rau cov kab mob septicemic (mob lossis subacute), urticariform, endocardial, mob caj dab thiab dermal.
Septicemic forms of swine erythema
Tom qab kis kab mob, cov kab mob mus rau cov tonsils lossis Peyer's thaj ua rau thaj, uas yog cov qauv lymphoid. Tom qab ntawd yuav nyob rau hauv cov ntshav, ua rau cov endothelium ntawm cov hlab ntsha ua tsaug rau neuraminidase, uas kuj txo cov ntshav cov ntshav. Qhov no tso tawm fibrin thiab ua rau ischemic necrosis ntawm perivascular cov ntaub so ntswg, hyaline thrombi, edema, tsub zuj zuj ntawm monocytes nyob rau hauv lub vascular phab ntsa, anemia, hemolysis, immunosuppression, coagulopathies, thiab thrombocytopenia.
The is characterized by:
- Ua npaws.
- Apathy.
- Anorexy.
- Pab mob caj dab.
- Enlarged spleen.
- Blepharoconjunctivitis.
Tawv Erheremas, muaj qhov tseeb ntawm daim tawv nqaij tawv nqaij thaj chaw poob qis.
The subacute form tshwm sim thaum tus npua muaj kev tiv thaiv kab mob. Lawv tsis tshua muaj tsos mob, thiab kub taub hau, ua pa tshwm sim, kev loj hlob qeeb thiab rho menyuam tawm.
Urticariform daim ntawv ntawm swine erythema
Nws feem ntau yog tsim los ntawm serovar 2 hauv cov tsiaj tiv thaiv kab mob. Cov kab mob hauv qhov no mus rau ntawm daim tawv nqaij, qhov twg nws ua rau cov kab mob dermal capillaries puas tsuaj thiab yog yam ntxwv los ntawm:
- mob npaws.
- Bad general state.
- Nkauj kho siab.
- Anorexy.
- Deep liab daim tawv nqaij papules, polyhedral, nrog rau saum npoo, kub thiab tsis mob ntawm lub ntsej muag sab nraud ntawm lub nraub qaum, cheeb tsam rov qab-lumbar, pob ntseg thiab nraub qaum. Cov kab mob no nce mus rau vesicles, qhov nqaij tawv nqaij tsaus nti nyob hauv nruab nrab thiab pob khaus uas poob.
Endocardial daim ntawv ntawm porcine erythrocyte kab mob
Nws yog tsim los ntawm evolution ntawm ib daim ntawv septicemic. A verrucous proliferative valvular endocarditis tsim nyob rau hauv lub mitral valve, uas tej zaum yuav nrog aortic stenosis. Qhov no tsim:
- Endothelial degeneration.
- thrombosis.
- Dysnoea.
- Tachypnea.
- Cyanosis.
- Sudden death by collapse.
Arthritic daim ntawv ntawm swine erythema
Kuj tshwm sim los ntawm evolution ntawm ib daim ntawv septicemic. A mob caj dab tshwm sim thawj zaug uas cov kab mob uas muaj cov kab mob sib xyaw ua ke tsim, ua rau cov leeg kub, mob, thiab o. Tus npua yuav nthuav tawm:
- Nkauj ntiv taw taug kev.
- pab.
- Ankylosis.
- Lordosis.
Dermal form of swine erythema
Nws yog tsim los ntawm evolution ntawm ib daim ntawv urticariform, nws tshwm sim tsuas yog nyob rau hauv cov chaw uas tsis zoo heev. Nws tshwm sim dermatitis nrog txias, qhuav thiab insensitive daim tawv nqaij uas peels tawm zoo li ntawv los yog cardboard.
Kab mob liab hauv npua
Kab mob Swine yog xav tias muaj cov tsos mob tshwm sim hauv npua ntawm 10 lub lis piam thiab 10 lub hlis ntawm hnub nyoog, nyob rau hauv ib puag ncig zoo thiab kev ua liaj ua teb, lossis yog tias muaj qhov tsis txaus ntawm cov phiaj xwm txhaj tshuaj. Qhov differential diagnosis kab mob liab hauv npua suav nrog cov kab mob swine nram qab no:
- Classical Swine Fever.
- African Swine Fever.
- Porcine salmonellosis.
- Pasteurella multocida serotype B.
- Clostridiosis.
Tom qab tau txais cov qauv (cov ntshav, spleen, plawv, siab thiab ntsws), yuav raug kuaj ncaj qha lossis tsis ncaj. Qhov direct laboratory diagnosis yog qhia, nyob rau hauv uas cov kab mob no yog tshawb nrhiav, los ntawm:
- Culture and isolation in blood agar media.
- PCR.
- Immunohistochemistry.
- Bacterioscopy (saib cov kab mob nyob rau hauv lub microscope).
Kev kuaj mob tsis ncaj nraim nrhiav tshuaj tiv thaiv kab mob liab, los ntawm:
Indirect ELISA: Txawm hais tias tsis muaj txiaj ntsig zoo, vim muaj kev txhaj tshuaj tiv thaiv thiab cov khoom nqa. Nws yog siv los tshuaj xyuas qib ntawm cov tshuaj tiv thaiv kab mob.
Tshuaj kab mob liab hauv npua
Kev tshem tawm ntawm tus kab mob no tsis raug txiav txim siab, vim muaj kev ruaj khov nyob hauv ib puag ncig thiab muaj cov neeg muaj tus kab mob ntau. Thaum muaj tus kab mob liab tshwm sim hauv zej zog npua, :
- Kev cais tawm ntawm cov neeg raug liam.
- Tshuaj tua kab mob nrog tshuaj tua kab mob beta-lactam xws li penicillins lossis amoxicillin.
- Hyperimmune sera, txawm tias lawv tsis siv lawm.
- Siv tus neeg mob.
- Tsev thiab tua kab mob.
Tshuaj tiv thaiv kab mob swine
Kev tiv thaiv yog ua tiav nrog kev txhaj tshuaj. Inactivated lossis monovalent serotype 2 lossis polyvalent tshuaj tiv thaiv yog siv. Lub sijhawm txhaj tshuaj yog raws li nram no:
- Piglets ntawm 3 lub hlis thawj koob, revaccinating ntawm 3 lub lis piam. Hauv Iberian npua revaccination txhua 3 lub hlis vim lawv txoj kev loj hlob ntev.
- Hauv thawj parity sows, ob koob (ntawm liab phem + parvovirus) 2-3 lub lis piam ua ntej mating.
- Nyob rau hauv yug me nyuam sows txhaj tshuaj tiv thaiv Mal Rojo + parvovirus 10 hnub tom qab farrowing.
- Tus txiv neej npua yuav tsum tau txhaj tshuaj txhua 6 lub hlis.
Txawm hais tias qhov no yog qhov xwm txheej uas feem ntau tshwm sim hauv kev ua liaj ua teb, peb nco ntsoov koj tias ntawm peb qhov chaw peb tawm tsam kev siv tsiaj, yog li peb qhov kev pom zoo yog tias koj muaj npua ua lub tuam txhab tsiaj ua liaj ua teb, khaws cia. ib tug zoo veterinary tswj kom nws muaj lub neej ntev thiab zoo siab.
