Falanqaynta Sababta Dhimashada Ba'an ee abuurka

Kiliinik ahaan, cudurada ugu badan ee keeni kara dhimashada degdega ah ee abuurka waxaa ka mid ah qandhada doofaarka ee Afrika, qandhada doofaarka caadiga ah, boogaha caloosha oo daran (dalool), septicaemia ba'an ee bakteeriyada (sida nooca B-Clostridium novyi, erysipelas), iyo dhaafitaanka xadka caaryada. sunta ku jirta quudinta. Intaa waxaa dheer, infekshannada kaadi mareenka ee abuurka ay keento Streptococcus suis waxay sidoo kale keeni kartaa dhimasho degdeg ah.

Beeryaradu waa xubin difaaceed oo muhiim ah oo ku lug leh jawaab celinta difaaca iyo sifaynta dhiigga, taas oo u adeegta sida goobta ugu muhiimsan ee dagaalka uu jidhku kula jiro cudur-sidaha. Sidaa darteed, inta lagu jiro infekshanka habaysan ee cudur-sidaha, beeryaradu waxay muujinaysaa falcelin daran. Splenitis ba'an, halkaasoo beeryaradu ay dhowr jeer ka weyn tahay tan caadiga ah, waxaa sababi kara cudurro ay ka mid yihiin qandhada doofaarka ee Afrika, qandhada doofaarka caadiga ah, iyo septicaemia ba'an ee bakteeriyada (taas oo ku lug yeelan karta bakteeriyada kala duwan sida streptococci iyo Clostridium novyi). Iyada oo ku saleysan isbeddellada bayoolajiga guud ee beeryarada, diiraddayadu waa qandhada doofaarka ee Afrika, qandhada doofaarka ee caadiga ah, iyo septicaemia bakteeriyada ee doofaarka. Porcine circovirus iyo fayrasyada taranka iyo neef-mareenka ee porcine caadi ahaan ma keenaan isbeddello cudur-sidaha guud ee beeryarada; Caadi ahaan circovirus wuxuu keenaa granulomatous splenitis, kaas oo lagu arki karo oo kaliya marka la eego mikroskoob.

Boogta gastric waxaa loola jeedaa dheef-shiid kiimikaad ba'an iyo dhiig-baxa gastric taasoo horseedaysa nabaad-guurka unugyada deegaanka, necrosis, ama dheef-shiid kiimikaad ee xabka caloosha, taasoo keentay nabarro boogaha wareega ah ama xitaa daloolinta caloosha. Kahor imaatinka qandhada doofaarka ee Afrika, boogaha gastric ayaa ahaa sababta ugu badan ee dhimashada Shiinaha. Waxaa xusid mudan in boogaha caloosha ee u dhow hunguriga ama pylorus ay leeyihiin muhiimad ogaanshaha, halka boogaha qaybaha kale ee caloosha aysan lahayn. Shaxda, wax boogaha boogaha ah laguma arko caloosha, markaa boogta gastric waxaa meesha laga saari karaa sababta dhimashada degdega ah ee abuurka.

Sawirka bidix ee hoose wuxuu muujinayaa nudaha beerka. Beerku wuxuu u muuqdaa mid gogo'an, oo ay ka buuxaan daloolo yaryar oo kala duwan oo u eg qaab dhismeed xumbo leh. Nabarada beerka xumbo leh ayaa ah isbedelo anatomical ah oo lagu garto oo uu keeno caabuqa Clostridium novyi ee doofaarka. Way adag tahay in la falanqeeyo sida Clostridium novyi uu dib ugu noqdo beerka una keeno dhaawac beerka.

Iyadoo loo marayo bayoolaji molecular, waxaan ka saari karnaa xumadda doofaarka ee Afrika iyo qandhada doofaarka caadiga ah. Cudurada bakteeriyada keeni kara dhimashada degdega ah ee abuurka waxaa ka mid ah erysipelas, Actinobacillus pleuropneumoniae, iyo Clostridium novyi. Si kastaba ha ahaatee, cudurrada bakteeriyada waxay sidoo kale soo bandhigaan goobo duullaan oo kala duwan iyo sifooyinka waxyeellada; Tusaale ahaan, Actinobacillus pleuropneumoniae kaliya ma keeno splenitis ba'an laakiin waxaa ka sii muhiimsan, necrotizing hemorrhagic pneumonia. Streptococcus suis waxay sababtaa nabarro maqaarka ah oo ballaaran. Cudurka guud ee beerka ayaa tilmaamaya jihada gaarka ah; beerka xumbo waa sida caadiga ah nabar lagu garto Clostridium novyi ee doofaarka. Baadhitaano kale oo yar yar ayaa xaqiijinaya Clostridium novyi inay tahay sababta dhimashada degdega ah ee abuurka. Natiijooyinka aqoonsiga dhaqanka bakteeriyada ayaa xaqiijinaya Clostridium novyi.

Xaaladdan oo kale, habab kala duwan ayaa loo isticmaali karaa dabacsanaan, sida beerka smears. Caadiyan, waa in aan bakteeriyadu ka muuqan beerka. Marka bakteeriyada la arko, oo nabarrada anatomical sida isbeddel beerka xumbo leh la arko, waxaa loo qaadan karaa inuu yahay cudur xinjirowga ah. Xaqiijin dheeraad ah ayaa lagu samayn karaa iyada oo la dhayalinayo unugyada beerka, oo muujinaya bakteeriya badan oo usha u samaysan. Dhaqanka bakteeriyada lagama maarmaan ma aha sababtoo ah Clostridium novyi waa mid ka mid ah bakteeriyada ugu adag ee dhaqanka.

Fahamka sifooyinka gaarka ah ee dhaawaca iyo goobaha cudur kasta waa muhiim. Tusaale ahaan, fayraska shuban-biyoodka faafa wuxuu ugu horrayn weeraraa unugyada epithelial ee xiidmaha yar, iyo dhaawaca xubnaha kale sida sambabada, wadnaha, ama beerka kuma jiraan xadkiisa. Duullaanka bakteeriyada waxay si adag ugu xidhan tahay wadooyin gaar ah; Tusaale ahaan, Clostridium tetani waxa kaliya oo ay ku qaadi kartaa nabarrada si qoto dheer u wasakhaysan oo leh isbeddello necrotic ah ama suppurative, halka dariiqyada kale aysan u horseedin caabuq. Infekshannada Actinobacillus pleuropneumoniae waxay u badan tahay inay ku dhacaan beeraha doofaarka ee leh hargabka iyo rabiyada been abuurka ah, maadaama fayrasyadani ay si fudud u dhaawacaan unugyada epithelial tracheal, taas oo u sahlaysa Actinobacillus pleuropneumoniae si ay u dhexgalaan oo u degaan alveoli. Dhakhaatiirta xooluhu waa inay fahmaan sifooyinka dhaawaca gaarka ah ee jirrada ka dibna isku daraan hababka baaritaanka shaybaarka sida bayoolaji molecular iyo microbiology si loo ogaado cudurka saxda ah.
