Uhlalutyo lonobangela wokufa ngokuqatha kwihagu

Ngokonyango, ezona zifo zixhaphakileyo ezinokubangela ukufa ngokuqatha kwiihagu ziquka i-African swine fever, i-classical swine fever, izilonda ezinzulu zesisu (perforation), i-acute bacterial septicemia (efana ne-B-type Clostridium novi, erysipelas), kwaye idlula umda wokungunda. ityhefu kwisondlo. Ukongeza, usulelo lwendlela yomchamo kwiihagu ezibangelwa yiStreptococcus suis lunokukhokelela ekufeni ngokuqatha.

Udakada lilungu elibalulekileyo lokhuselo lomzimba elibandakanyeka kwiimpendulo zokhuselo lomzimba kunye nokuhluzwa kwegazi, lisebenza njengendawo ephambili yokulwa kumlo womzimba ngokuchasene neentsholongwane. Ngoko ke, ngexesha losulelo lwe-systemic yi-pathogens, i-spleen ibonisa ukuphendula okunzima. I-acute splenitis, apho udakada bukhulu ngokuphindwe kaninzi kunesiqhelo, inokubangelwa zizifo ezifana ne-African swine fever, classical swine fever, kunye ne-acute bacterial septicemia (enokubandakanya iibhaktheriya ezahlukeneyo ezifana ne-streptococci kunye ne-Clostridium novi). Ngokusekelwe kutshintsho olubi kakhulu lwesifo kwi-spleen, sigxile kwi-African swine fever, classical swine fever, kunye ne-bacterial septicemia ezihagwini. I-porcine circovirus kunye ne-porcine reproductive kunye ne-respiratory syndrome virus ayivelisi utshintsho olukholisayo lwe-pathological kwi-spleen; I-circovirus idla ngokubangela i-granulomatous spleitis, ebonwa kuphela nge-microscope.

Isilonda esiswini sibhekiselele ekungangeni kakuhle kokutya kunye nokopha kwesisu okukhokelela kukhukuliseko lwezicubu zengingqi, i-necrosis, okanye ukugaywa ngokuzenzekelayo kwe-gastric mucosa, okukhokelela kwizilonda ezijikelezayo zezilonda okanye ukugqobhoza kwesisu. Phambi kokufika komkhuhlane wehagu waseAfrika, izilonda zesisu zazingoyena nobangela wokufa kwehagu zaseTshayina. Kuyaphawuleka ukuba izilonda zesisu kufuphi nommizo okanye i-pylorus zinentsingiselo yokuxilongwa, kanti izilonda kwezinye iindawo zesisu azinjalo. Kulo mzobo, akukho zilonda zezilonda esiswini zibonwayo, kungoko isilonda esiswini sinokukhutshwa njengonobangela wokufa ngokuqatha kwiihagu.

Umfanekiso osezantsi ngasekhohlo ubonisa izicubu zesibindi. Isibindi sibonakala si-lolated, sizaliswe ziimbobo ezincinci ezahlukeneyo ezifana nesakhiwo esinamagwebu. Izilonda zesibindi ezinogwebu luphawu lotshintsho lwe-anatomical olubangelwa lusulelo lweClostridium novi kwiihagu. Kunzima ukuhlalutya indlela iClostridium novi ibuyisela ngayo ukufikelela kwisibindi kwaye ibangele umonakalo wesibindi.

Ngebhayoloji yemolekyuli, sinokukhuphela ngaphandle i-African swine fever kunye ne-classical swine fever. Izifo zebhaktiriya ezinokubangela ukufa ngokukhawuleza kwiihagu ziquka i-erysipelas, i-Actinobacillus pleuropneumoniae, kunye ne-Clostridium novi. Nangona kunjalo, izifo zebhaktheriya zikwabonisa iindawo ezahlukeneyo zokuhlasela kunye neempawu zomonakalo; umzekelo, i-Actinobacillus pleuropneumoniae ayibangeli kuphela i-splenitis ebukhali kodwa okona kubaluleke kakhulu, i-necrotizing pneumonia ye-hemorrhagic. I-Streptococcus suis ibangela izilonda ezinzulu zolusu. I-gross pathology yesibindi ibonisa ulwalathiso oluthile; Isibindi esinamagwebu siqhelekile ukuba sisilonda seClostridium novi kwiihagu. Uphononongo olongezelelekileyo lwemikroskopu luqinisekisa ukuba iClostridium novi ingunobangela wokufa ngokuqatha kwehagu. Iziphumo zokuchongwa kwentsholongwane yentsholongwane ziqinisekisa iClostridium novi.

Kule meko, iindlela ezahlukeneyo zinokusetyenziswa ngokuguquguqukayo, ezifana ne-smears yesibindi. Ngokuqhelekileyo, akukho bhaktheriya kufuneka ibonakale esibindini. Nje ukuba iibhaktheriya zibonwe, kwaye izilonda ze-anatomical ezifana notshintsho olufana nesibindi olunogwebu lubonwa, kunokuchazwa njengesifo se-clostridial. Ukuqinisekiswa okongezelelekileyo kunokwenziwa ngokudyojwa kwe-HE kwezicubu zesibindi, kutyhile iibhaktheriya ezininzi ezimile okwentonga. Inkcubeko yebhaktiriya ayiyimfuneko kuba iClostridium novi yenye yezona bhaktheriya ezinzima kwinkcubeko.

Ukuqonda iimpawu ezithile zomonakalo kunye neendawo zesifo ngasinye kubalulekile. Ngokomzekelo, intsholongwane ye-porcine epidemic isifo sohudo ihlasela iiseli ze-epithelial zamathumbu amancinci, kwaye umonakalo kwamanye amalungu afana nemiphunga, intliziyo, okanye isibindi ayikho ngaphakathi kwendawo yayo. Ukuhlasela kwebhaktheriya kuxhomekeke ngokuthe ngqo kwiindlela ezithile; umzekelo, i-Clostridium tetani inokosulela kuphela ngamanxeba angcoliseke kakhulu anotshintsho lwe-necrotic okanye i-suppurative, ngelixa ezinye iindlela zingakhokelela kusulelo. Usulelo lwe-Actinobacillus pleuropneumoniae lunokwenzeka kakhulu kwiifama zehagu ezinomkhuhlane kunye ne-pseudo-rabies, njengoko ezi ntsholongwane ziyonakalisa ngokulula iiseli ze-tracheal epithelial, zenza kube lula kwi-Actinobacillus pleuropneumoniae ukuba ingene kwaye ihlale kwi-alveoli. Oogqirha bezilwanyana kufuneka baqonde iimpawu zomonakalo welungu elithile kwisifo ngasinye baze badibanise iindlela zokuvavanya elebhu ezifana nebhayoloji yemolekyuli kunye ne-microbiology yokuxilongwa ngokuchanekileyo kwesifo.
