Pane umhutu, panogona kunge paine gonye remoyo
Heartwormchirwere chirwere chakakomba chemhuka dzinoyamwisa. Mhuka huru dzine utachiona imbwa, katsi uye ferrets. Kana gonye rakura, rinonyanya kugara mumwoyo, mumapapu uye netsinga dzeropa dzine chekuita nemhuka. Kana gonye rakura uye richikonzera zvirwere, pachava nehosha yemapapu, kusashanda zvakanaka kwemoyo, kukuvara uye kufa kwedzimwe nhengo.
Heartworm ibug inoshamisa. Haikwanise kutapurirana zvakananga pakati pembwa, katsi nekatsi, imbwa nekatsi. Inofanirwa kutumirwa kuburikidza nemurevereri. MuUnited States, chirwere chegomarara remoyo chiri kupararira mumatunhu ese makumi mashanu, asi chakanyanya kuzara muGulf of Mexico, Mississippi River Basin nedzimwe nzvimbo, nekuti kune humhutu hwakawanda munzvimbo idzi. Kune zviitiko zvehutachiona munzvimbo dzese dzenyika yedu, uye huwandu hwehutachiona mune dzimwe nzvimbo hunopfuura 50%.
Imbwa ndidzo dzinonyanya kurwisa moyo, izvo zvinoreva kuti honye chete inogara muimbwa inogona kusangana uye kubereka vana. Kunyanya, vanhu havazotapukirwa neheartworm kubva kumhuka dzinovaraidza. Muzviitiko zvisingawanzoitiki, vanhu vanogona kutapukirwa neheartworm mushure mekurumwa nehumhutu hune utachiona. Zvisinei, nokuti vanhu havasi ivo vanogamuchira, makonye anowanzofa asati atamira kutsinga dzemwoyo nemapapu.
Kukura kwehonye yemwoyo mumbwa
Honye yemwoyo yevakuru inogara mukati memwoyo yembwa. Vakuru vechikadzi vanobereka microfilariae, uye mazai anoyerera kumativi akasiyana-siyana neropa. Zvisinei, idzi microfilariae hadzigoni kuramba dzichikura, uye dzinofanira kumirira kusvika kwoumhutu. Kana umhutu hukaruma imbwa ine utachiona, hunotapukirwawo nemicrofilariae. Mumazuva 10-14 anotevera, apo nharaunda uye tembiricha zvakakodzera uye mosquito haina kuurayiwa, iyo microfilariae inokura kuita mhute inotapukira uye inogara muumhutu. Makonye ane utachiona anogona kutapurirwa imbwa chete nekuruma kusvika umhutu hwaruma imwe imbwa zvakare.
Zvinotora 6-7 mwedzi kuti makonye ane utachiona akure kuita gonye remoyo. Hora dzinosangana zvakare, uye hadzi dzinoregedzera vana vadzo muropa rembwa zvakare kuti dzipedze kutenderera kwose. Upenyu hurefu hwemwoyo wevanhu vakuru mumbwa hunenge makore 5-7. Varume vakareba 10-15cm uye vakadzi 25-30cm kureba. Paavhareji, kune dzinenge gumi neshanu heartworms mumbwa dzine utachiona, kusvika ku250. Nhamba chaiyo yehonye inowanzotongwa nemutoro wehonye. Kuburikidza nemichina yekuedza ropa, antigen test inogona kunyatsoona nhamba yevakadzi vakuru mumbwa, uye kuongorora kwe microfilaria kunogona kusimbisa kuti kune vanhu vakuru chete asiwo mapere mumbwa.
Kune mamwe maitiro ekuongorora mwoyo wemwoyo muUnited States: kuongorora kwekutanga kwemoyo wemwoyo kunogona kutanga mushure mokunge imbwa ine mwedzi 7; Varidzi vezvipfuyo vakanganwa nguva yekupedzisira kudzivirira heartworm; Imbwa dziri kushandura zvinodhaka zvinowanzoshandiswa kudzivirira heartworm; Munguva ichangopfuura, ndakatora imbwa yangu kunzvimbo yakajairika yemwoyo; Kana kuti imbwa pachayo inogara munzvimbo yakajairika yemwoyo; Mushure mekuongororwa, kudzivirira kwemoyo wemwoyo kunotanga.
Zviratidzo uye kudzivirira kwechirwere chemoyo chemoyo mumbwa
Kuoma kwechirwere chemoyo chemoyo chakabatana zvakananga nehuwandu hwehonye mumuviri (mutoro wehonye), kureba kwehutachiona uye kusimba kwemuviri wembwa. Kuwanda kwehonye mumuviri, nguva yakareba yehutachiona, imbwa inonyanya kushanda uye yakasimba, uye zviratidzo zviri pachena. MuUnited States, chirwere chemwoyo chakakamurwa kuva mamakisi mana. Iyo yakakwirira giredhi, iyo yakanyanya kukomba chirwere.
Giredhi 1: asymptomatic kana zvinyoro zviratidzo, senge apo neapo kukosora.
Giredhi 2: zvinyoro kusvika pakati nepakati zviratidzo, senge apo neapo kukosora uye kuneta mushure mekuita zvine mwero.
Giredhi 3: zviratidzo zvakakomba, sekuneta kwemuviri, kurwara, chikosoro chisingaperi uye kuneta mushure mekuita zvinyoro. Zviratidzo zvekunetseka kufema uye kupera kwemoyo zvinowanzoitika. Kune giredhi 2 ne3 cardiac filariasis, kuchinja kwemoyo nemapapu kunowanzoonekwa pachipfuva X-rays.
Giredhi 4: inozivikanwawo sevena cava syndrome. Kuremerwa nehonye kunorema zvekuti ropa rinoyerera richidzokera kumoyo rinovharika nehonye zhinji mutsinga dzeropa. Vena cava syndrome inotyisa hupenyu. Kurumidza kuvhiyiwa resection yeheartworm ndiyo yega nzira yekurapa. Kuvhiya kune ngozi. Kunyange kana iri kuvhiyiwa, imbwa dzakawanda dzine vena cava syndrome dzinozofa.
FDA yakabvumira kuti melassomine dihydrochloride (mazita ekutengeserana immicide uye diroban) inogona kubaiwa kurapa gonye remoyo reGrade 1-3. Mushonga une mhedzisiro yakakura, uye mutengo wekurapa wese unodhura. Kuongororwa nguva nenguva, X-rays uye jekiseni rezvinodhaka zvinodiwa. Kubviswa kwe microfilariae, FDA yakabvumidza mumwe mushonga, mukana wakawanda wembwa (imidacloprid uye moxikeding), kureva "aiwalker".
MuUnited States, mishonga yese inotenderwa neFDA kudzivirira heartworm mishonga yekurapa, kusanganisira madonhwe uye mahwendefa emuromo akaiswa paganda (Ewok, hombe chipfuyo, imbwa Xinbao, nezvimwewo), nekuti heartworm prophylaxis haingauraye moyo wevakuru, asi moyoworm. kudzivirira imbwa dzine chirwere chemoyo chevanhu vakuru kunogona kukuvadza kana kuuraya. Kana microfilaria iri muropa rembwa, matanho ekudzivirira anogona kutungamirira kukufa kamwe kamwe kwemicrofilaria, zvichikonzera kuvhunduka sekuita uye kufa kunogona kuitika. Naizvozvo, zvinodikanwa kuita bvunzo yekudzivirira yeheartworm gore rega rega pasi pekutungamirwa uye mazano evanachiremba. "Kunamata Chong Shuang" inzira inodzinga zvipembenene ine muromo wakapinza. Iyo haina kunanga zvakananga microfilariae, asi inoedza kudzivirira kurumwa neumhutu uye kudimbura tambo yekutapurirana kubva pakati, inova yakachengeteka zvakanyanya.
Chaizvoizvo, kudzivirira chirwere chemoyo chemoyo kwakakosha kupfuura kurapwa. Sezvinogona kuonekwa kubva mukukura kwechirwere chemoyo chinotsanangurwa pamusoro apa, kurima umhutu ndiyo inonyanya kukosha. Hutano hunogona kuvimbiswa chete nekucheka kurumwa neumhutu. Izvi zvichava zviri nani kune imbwa refu refu, nepo imbwa dzebvudzi pfupi dzinoda kutariswa zvakanyanya.
