Ngokuphucuka kwemigangatho yokuphila kwabantu, ukugcina izinja kuye kwaba yifashoni kunye nekhusi lokomoya, kwaye izinja ziye ngokuthe ngcembe zaba ngabahlobo kunye namaqabane asondeleyo abantu.Nangona kunjalo, ezinye izifo ezibangelwa yintsholongwane ziyingozi kakhulu kwizinja, zichaphazela kakhulu ukukhula kwazo, ukukhula, kunye nokuzala, kwaye ngamanye amaxesha zide zibeke ubomi babo engozini.Izinto ze-pathogenic zezifo zentsholongwane ye-canine zihluke, kwaye iimpawu zabo zeklinikhi kunye neengozi nazo ziyahluka kakhulu.Eli nqaku ikakhulu lizisa i-canine distemper, isifo se-canine parvovirus Izifo ezininzi eziqhelekileyo zentsholongwane kunye neengozi, ezifana ne-canine parainfluenza, zibonelela ngereferensi yokunakekelwa kwezilwanyana kunye nokukhusela nokulawula izifo.
1.I-Canine distemper
I-Canine distemper yenziwa yintsholongwane enkulu yentsholongwane yemasisi yeParamyxoviridae.Ijenome yentsholongwane yi-negative strand RNA.Intsholongwane yeCanine distemper ineserotype enye kuphela.Inja egulayo ngowona mthombo wosulelo.Kukho inani elikhulu leentsholongwane empumlweni, iimfihlo zamehlo kunye namathe enja egulayo.Kukho neentsholongwane ezithile egazini kunye nomchamo wenja egulayo.Ukudibana ngokuthe ngqo phakathi kwezinja ezisempilweni kunye nezinja ezigulayo kuya kubangela usulelo lwentsholongwane, Intsholongwane isasazwa ikakhulu ngephecana lokuphefumla kunye ne-digestive tract, kwaye isifo sinokudluliselwa ngokuthe nkqo ngokukhuhla komntwana.Izinja zayo yonke iminyaka, izini, kunye neentlobo zisesichengeni, kunye neenjana ezingaphantsi kweenyanga ezimbini ubudala.
Inokukhuselwa ngamajoni oomama abakhulelweyo, kunye neqondo eliphezulu losulelo olwenzeka kwi-2 ukuya kwiinyanga ezili-12 ubudala.Izinja ezosulelwe yi-canine distemper virus zinokufumana ukukhuselwa kwamajoni omzimba emva kokuchacha.Emva kokusuleleka, ukubonakaliswa okuphambili kwenja esulelekileyo kukunyuka kweqondo lokushisa ngaphezu kwe-39%.Inja igxininisekile ngengqondo, kunye nokunciphisa ukutya, i-purulent secretions ephuma emehlweni kunye neempumlo, kunye nephunga elibi.Inja egulayo inokubonisa ubushushu be-biphasic, ngokunyuka kokuqala kweqondo lokushisa, elihla liye ngokuqhelekileyo emva kweentsuku ezi-2.Emva kweentsuku ezi-2 ukuya kwezi-3, ubushushu buphakama kwakhona, kwaye imeko iyancipha ngokuthe ngcembe.Inja egulayo idla ngokuba neempawu zokugabha kunye nenyumoniya, kwaye inokuba nesifo sorhudo, ibonakalisa iimpawu zemithambo-luvo.Kwisifo esibi kakhulu, ekugqibeleni siyafa ngenxa yokubhitya okugqithisileyo.Izinja ezigulayo kufuneka zibekwe zodwa ngokukhawuleza kwaye zinyangwe, kwaye usulelo kwangoko kufuneka lunyangwe nge-antiserum.Kwangaxeshanye, amachiza alwa nentsholongwane kunye nezixhasi zokuzikhusela komzimba kufuneka zisetyenziswe, kwaye unyango olujoliswe kuyo kufuneka luthathwe.Izitofu zokugonya zingasetyenziselwa ukuthintela amajoni omzimba kwesi sifo.
2.Isifo se-canine parvovirus
I-Canine parvovirus lilungu lohlobo lwe-parvovirus yosapho lwe-parvoviridae.I-genome yayo yintsholongwane enye ye-DNA.Izinja ngumkhosi wendalo wesi sifo.Esi sifo sichaphazeleka kakhulu, kunye nezinga lokufa kwe-10% ~ 50%.Uninzi lwabo lunokosuleleka.Izinga leziganeko zolutsha liphezulu.Esi sifo sifutshane ngexesha, siphezulu ngokusweleka, kwaye sinomonakalo omkhulu kwishishini lezinja.Esi sifo sinokusasazwa ngokuqhagamshelana ngokuthe ngqo kunye nokudluliselwa koqhagamshelwano olungathanga ngqo.Ukukhutshwa okusulelekileyo kunye ne-excreta kunokusasaza intsholongwane, Umchamo wezinja zokubuyisela kwakhona uqulethe iintsholongwane ezinokuthi zikhutshwe ixesha elide.Esi sifo sisasazwa kakhulu ngomgudu wokugaya ukutya, kwaye sinokwenza imeko ibe mandundu kwaye inyuse ukufa ngenxa yemozulu ebandayo nexineneyo, iimeko zokungacoceki, kunye nezinye iimeko.Izinja ezosulelekileyo zingabonakalisa njenge-myocarditis ebukhali kunye ne-enteritis, ngokuqala ngokukhawuleza kwe-myocarditis kunye nokufa ngokukhawuleza.Ukufa kungenzeka kwiiyure ezimbalwa emva kokuqala, kunye norhudo, ukuhlanza, kunye nokwanda kobushushu bomzimba, ukubetha kwentliziyo ngokukhawuleza kunye nobunzima bokuphefumla.Uhlobo lwe-enteritis luqala ngokugabha, lulandelwe lurhudo, ilindle elinegazi, ivumba elibi, ukuxinezeleka kwengqondo, ukwanda kobushushu bomzimba ngemibala engaphezu kwama-40, ukuphelelwa ngamanzi emzimbeni, nokudinwa kakhulu okukhokelela ekufeni.Esi sifo sinokuthintelwa ngokugonywa ngogonyo.
3. I-canine parainfluenza
I-Canine parainfluenza sisifo esosulelayo esibangelwa yi-parainfluenza virus type 5. I-pathogen lilungu le-Paramyxoviridae paramyxovirus.Le ntsholongwane inakho kuphela!I-1 serotype ye-canine parainfluenza, enokuthi isuleleke ngeminyaka eyahlukeneyo kunye neentlobo.Kwizinja ezincinci, imeko inzima, kwaye isifo sisasazeka ngokukhawuleza kunye nexesha elifutshane lokufukamela.Ukuqala kwesi sifo ezinjeni kubonakala ngokuqala ngequbuliso, ukunyuka kobushushu bomzimba, ukunciphisa ukutya, ukudandatheka kwengqondo, i-catarrhal rhinitis kunye ne-bronchitis, ubuninzi be-purulent secretions kwi-ekhaleni lempumlo, ukukhohlela kunye nobunzima bokuphefumla, izinga eliphezulu lokufa kwezinja ezincinci. , izinga lokufa eliphantsi kwizinja ezikhulileyo, kunye nokugula kakhulu kwizinja ezincinci emva kosulelo, Ezinye izinja ezigulayo zinokufumana ukuphazamiseka kwemithambo-luvo kunye nokuphazamiseka kwemoto.Izinja ezigulayo ngowona mthombo wosulelo, kwaye intsholongwane ifumaneka ikakhulu kwinkqubo yokuphefumla.Ngosulelo lokuphefumla, esi sifo sinokugonyelwa ukukhusela amajoni omzimba.
