Ukuhlaziywa Kwembangela Yokufa Kabuhlungu Engulubeni

Ngokomtholampilo, izifo ezivame kakhulu ezingabangela ukufa kakhulu ezingulubeni zihlanganisa i-African swine fever, i-classical swine fever, izilonda ezinzima zesisu (i-perforation), i-acute bacterial septicemia (njenge-B-type Clostridium novi, erysipelas), kanye nokweqa umkhawulo wesikhunta. ubuthi emfundweni. Ukwengeza, izifo ze-urinary tract ezingulubeni ezibangelwa i-Streptococcus suis nazo zingaholela ekufeni okunzima.

Ubende luyisitho esibalulekile sokuzivikela komzimba esibandakanyeka ekuphenduleni amasosha omzimba nasekuhlungeni igazi, sisebenza njengendawo yempi enkulu ekulweni komzimba namagciwane. Ngakho-ke, ngesikhathi sokutheleleka kwesistimu ngama-pathogens, i-spleen ibonisa ukusabela okunzima. I-spleenitis ebukhali, lapho ubende bukhulu ngokuphindwe izikhathi eziningana kunokuvamile, lungabangelwa izifo ezifana ne-African swine fever, i-classical swine fever, kanye ne-acute bacterial septicemia (engabandakanya amagciwane ahlukahlukene njenge-streptococci ne-Clostridium novi). Ngokusekelwe ezinguqukweni ezimbi kakhulu ze-pathological ku-spleen, ukugxila kwethu ku-African swine fever, i-classical swine fever, kanye ne-bacterial septicemia ezingulubeni. I-porcine circovirus kanye ne-porcine reproductive and respiratory syndrome virus ngokuvamile azikhiqizi izinguquko ezikholisayo ze-pathological ku-spleen; I-circovirus ngokuvamile ibangela i-granulomatous splenitis, ebonakala kuphela ngesibonakhulu.

Izilonda zesisu zisho ukuqunjelwa okunamandla nokopha kwesisu okuholela ekugugulekeni kwezicubu zendawo, i-necrosis, noma ukugayeka kokudla esiswini, okuholela ezilonda eziyindilinga zezilonda noma ukubhobozwa kwesisu. Ngaphambi kokufika kwe-African swine fever, izilonda zesisu zaziyimbangela ehamba phambili yokufa kwezingulube zaseShayina. Kuyaphawuleka ukuthi izilonda zesisu eduze komminzo noma i-pylorus zinokubaluleka kokuxilonga, kanti izilonda kwezinye izingxenye zesisu azinawo. Emfanekisweni, azikho izilonda zezilonda esiswini, ngakho-ke isilonda esiswini singakhishwa njengembangela yokufa okukhulu kwezingulube.

Isithombe esingezansi kwesokunxele sibonisa izicubu zesibindi. Isibindi sibonakala si-lolated, sigcwele izimbotshana ezincane ezihlukahlukene ezifana nesakhiwo esinamagwebu. Izilonda zesibindi ezinegwebu ziyizimpawu zezinguquko ze-anatomical ezibangelwa ukutheleleka kwe-Clostridium novi ezingulubeni. Kunzima ukuhlaziya ukuthi iClostridium novi ibuyela kanjani emuva ukuze ifinyelele esibindini futhi ibangele ukulimala kwesibindi.

Ngebhayoloji yamangqamuzana, singayikhipha i-African swine fever kanye ne-classical swine fever. Izifo ezibangelwa amagciwane ezingabangela ukufa kakhulu ezinsikazini zihlanganisa i-erysipelas, i-Actinobacillus pleuropneumoniae, ne-Clostridium novi. Kodwa-ke, izifo ezibangelwa amagciwane nazo zibonisa izindawo ezihlukene zokuhlasela kanye nezici zomonakalo; ngokwesibonelo, i-Actinobacillus pleuropneumoniae ayibangeli nje kuphela i-splenitis eyingozi kodwa okubaluleke kakhulu, inyumoniya ene-necrotizing hemorrhagic. I-Streptococcus suis idala izilonda zesikhumba ezibanzi. I-gross pathology yesibindi ikhombisa isiqondiso esithile; isibindi esinamagwebu ngokuvamile siyisilonda se-Clostridium novi ezingulubeni. Ukuhlola okwengeziwe nge-microscopic kuqinisekisa i-Clostridium novi njengembangela yokufa okunamandla kwezingulube. Imiphumela yokuhlonza isiko lamagciwane iqinisekisa i-Clostridium novi.

Kulokhu, izindlela ezihlukahlukene zingasetshenziswa ngokuguquguqukayo, njenge-smear yesibindi. Ngokuvamile, awekho amagciwane okufanele abonakale esibindini. Uma amagciwane ebonwa, futhi izilonda ze-anatomical ezifana nezinguquko zesibindi ezinogwebu zibonakala, kungase kuthiwe isifo se-clostridial. Ukuqinisekisa okwengeziwe kungenziwa ngokungcoliswa kwe-HE kwezicubu zesibindi, kwembule amagciwane amaningi amise okwenduku. Isiko lama-bacterium akudingekile ngoba i-Clostridium novi ingenye yamagciwane anzima kakhulu esikweni.

Ukuqonda izici ezithile zomonakalo nezindawo zesifo ngasinye kubalulekile. Isibonelo, igciwane lesifo sohudo eliwubhubhane lwezingulube lihlasela ngokuyinhloko amangqamuzana e-epithelial amathumbu amancane, futhi umonakalo kwezinye izitho ezinjengamaphaphu, inhliziyo, noma isibindi awekho ngaphakathi kwendawo yawo. Ukuhlasela kwamagciwane kuncike kakhulu ezindleleni ezithile; ngokwesibonelo, i-Clostridium tetani ingangena kuphela ngamanxeba angcoliswe kakhulu anezinguquko ze-necrotic noma zokuphefumula, kuyilapho ezinye izindlela zingaholeli ekuthelelekeni. Izifo ze-Actinobacillus pleuropneumoniae cishe zenzeka emapulazini ezingulube ezinomkhuhlane kanye namarabi mbumbulu, njengoba la magciwane alimaza kalula amaseli e-tracheal epithelial, okwenza kube lula ku-Actinobacillus pleuropneumoniae ukuthi ingene futhi ihlale ku-alveoli. Odokotela bezilwane kumele baqonde izici zokulimala okuqondene nesitho ngasinye zesifo ngasinye bese behlanganisa izindlela zokuhlola zaselabhorethri ezifana ne-molecular biology kanye ne-microbiology ukuze bathole isifo esinembile.
