Ongororo Yechikonzero Chekufa Kwakasimba muSowe

Mukiriniki, zvirwere zvinowanzoitika zvinogona kukonzeresa kufa kwesowe zvinosanganisira African swine fever, classical swine fever, yakanyanya gastric ulcers (perforation), acute bacterial septicemia (seB-type Clostridium novi, erysipelas), uye inodarika muganhu wekuumbwa. chepfu mukudya. Pamusoro pezvo, zvirwere zveweti mumasowe zvinokonzerwa neStreptococcus suis zvinogonawo kutungamirira kurufu rwakanyanya.

Iyo spleen inhengo yakakosha yekudzivirira yemuviri inobatanidzwa mukupindura kwekudzivirira uye kusefa kweropa, ichishanda senhandare huru yehondo mukurwisa kwemuviri hutachiona. Nokudaro, panguva yehutachiona hwehutachiona nehutachiona, spleen inoratidza maitiro akaoma. Acute splenitis, uko spleen yakakura kakawanda pane yakajairika, inogona kukonzerwa nezvirwere zvakaita seAfrican swine fever, classical swine fever, uye acute bacterial septicemia (iyo inogona kusanganisira mabhakitiriya akasiyana se streptococci neClostridium novi). Zvichienderana nekuchinja kukuru kwezvirwere muspleen, tarisiro yedu ndeyeAfrica swine fever, classical swine fever, uye bacterial septicemia munguruve. Porcine circovirus uye porcine reproductive and respiratory syndrome virus kazhinji haibudisi inogutsa gross pathological change in the spleen; Circovirus kazhinji inokonzera granulomatous splenitis, iyo inoonekwa chete pasi pemaikorosikopu.

Chironda chemudumbu chinoreva kusadya zvakanaka uye kubuda ropa kwegastric kunotungamira mukukukurwa kwetishu, necrosis, kana autodigestion yegastric mucosa, zvichikonzera maronda emaronda akatenderedza kana kutopwa kwegastric. Kusati kwasvika kweAfrica swine fever, maronda emudumbu ndiwo ainyanya kukonzera rufu musowe dzekuChina. Zvinokosha kuziva kuti maronda emudumbu ari pedyo negurokuro kana pylorus ane zvaanoreva kuongororwa, nepo maronda ari mune dzimwe nzvimbo dzemudumbu haana. Mumufananidzo, hapana maronda emaronda anoonekwa mudumbu, saka gastric ulcer inogona kubviswa sechikonzero chekufa kwakanyanya mumhou.

Mufananidzo wezasi wekuruboshwe unoratidza chiropa. Chiropa chinoratidzika kunge chakasungirirwa, chakazadzwa nemapores madiki akasiyana-siyana akafanana nechimiro chine furo. Maronda echiropa ane furo maitiro ekuchinja kweanatomical kunokonzerwa nechirwere cheClostridium novi munguruve. Zvakaoma kuongorora kuti Clostridium novy inodzokera sei kusvika pachiropa uye kukonzera kukuvara kwechiropa.

Kuburikidza nemolecular biology, tinogona kusabvisa African swine fever uye classical swine fever. Zvirwere zvemabhakitiriya zvinogona kukonzera kufa zvakanyanya musowe zvinosanganisira erysipelas, Actinobacillus pleuropneumoniae, uye Clostridium novi. Zvisinei, zvirwere zvebhakitiriya zvinoratidzawo nzvimbo dzakasiyana dzekupinda uye maitiro ekukuvadza; semuenzaniso, Actinobacillus pleuropneumoniae haingokonzereri acute splenitis asi zvinonyanya kukosha, necrotizing hemorrhagic pneumonia. Streptococcus suis inokonzera maronda akawanda eganda. The gross pathology yechiropa inoratidza nzira chaiyo; foamy chiropa chinowanzoita chironda cheClostridium novy munguruve. Imwezve ongororo yemicroscopic inosimbisa Clostridium novi sechikonzero chekufa kwakanyanya kwenguruve. Mabhakitiriya etsika yekuzivikanwa mhedzisiro inosimbisa Clostridium novi.

Muchiitiko ichi, nzira dzakasiyana dzinogona kushandiswa zviri nyore, senge chiropa smears. Kazhinji, hapana mabhakitiriya anofanira kuonekwa muchiropa. Kana mabhakitiriya achinge aonekwa, uye zvironda zveanatomical senge shanduko yefoamy chiropa-yakaonekwa, inogona kunzi ichirwere checlostridial. Imwezve ongororo inogona kuitwa kuburikidza neHE kusvibiswa kwechiropa, kuburitsa mabhakitiriya akawanda akaita setsvimbo. Bacterial tsika haidiwi nekuti Clostridium novy nderimwe remabhakitiriya akaoma kutsika.

Kunzwisisa maitiro ekukuvadza uye nzvimbo dzechirwere chimwe nechimwe kwakakosha. Semuyenzaniso, porcine denda remanyoka utachiona hunonyanya kurwisa epithelial masero emudumbu mudiki, uye kukuvadza mune dzimwe nhengo dzakadai semapapu, moyo, kana chiropa hazvisi mukati mechikamu chayo. Kupinda kwebhakitiriya kunotsamira panzira dzakananga; semuenzaniso, Clostridium tetani inogona kungotapukira kuburikidza nemaronda akanyanya kusvibiswa ane necrotic kana suppurative shanduko, nepo dzimwe nzira dzisingatungamirire kutapukira. Actinobacillus pleuropneumoniae zvirwere zvinowanzoitika mumapurazi enguruve ane furuwenza uye pseudo-rabies, sezvo mavhairasi aya anokuvadza nyore nyore tracheal epithelial masero, zvichiita kuti zvive nyore kuti Actinobacillus pleuropneumoniae ipinde uye igare mualveoli. Veterinarians vanofanirwa kunzwisisa iyo nhengo-chaiyo kukuvara maitiro echirwere chega chega uye vobva vasanganisa nzira dzekuyedza marabhoritari senge molecular biology uye microbiology yekuongororwa kwechirwere.
