Lapho kunomiyane, kungase kube nesikelemu senhliziyo
Isibunu senhliziyoisifo yisifo esibi sezilwane ezifuywayo ezifuywayo. Izilwane ezifuywayo eziyinhloko ezingenwe yilesi sifo izinja, amakati nama-ferrets. Lapho isikelemu sikhula, sihlala kakhulu enhliziyweni, emaphashini kanye nasemithanjeni yegazi ehlobene nezilwane. Lapho isibungu sikhula futhi sibangela izifo, kuzoba nesifo esibi samaphaphu, ukwehluleka kwenhliziyo, ukulimala nokufa kwezinye izitho.
I-Heartworm iyisiphazamisi esingavamile. Akwazi ukudluliselwa ngokuqondile phakathi kwezinja, amakati namakati, izinja namakati. Kufanele idluliselwe ngomxhumanisi. E-United States, isifo se-heartworm sisakazeka kuzo zonke izifundazwe ezingu-50, kodwa ikakhulukazi sigxile eGulf of Mexico, emfuleni iMississippi River Basin nakwezinye izindawo, ngoba kunomiyane abaningi kulezi zindawo. Kunezigameko zokutheleleka kuzo zonke izingxenye zezwe lethu, futhi izinga lokutheleleka kwezinye izindawo lingaphezu kwama-50%.
Izinja ziyi-heartworm, okusho ukuthi i-heartworm kuphela ehlala ezinjeni engahlangana futhi ikhiqize inzalo. Ikakhulukazi, abantu ngeke bangenwe i-heartworm evela ezifuyweni. Ezimweni ezingavamile kuphela, abantu bangase batheleleke nge-heartworm ngemva kokulunywa omiyane abanaleli gciwane. Nokho, ngenxa yokuthi abantu ababona abavakashi, izibungu ngokuvamile ziyafa ngaphambi kokuba zifudukele emithanjeni yenhliziyo namaphaphu.
Ukukhula kwesikelemu ezinjeni
I-heartworm yabantu abadala ihlala ohlelweni lwenhliziyo nemithambo yezinja. Abantu abadala besifazane bazala ama-microfilariae, futhi amaqanda agelezela ezingxenyeni ezihlukahlukene ngegazi. Nokho, lezi microfilaria azikwazi ukuqhubeka zikhula, futhi zidinga ukulinda ukufika komiyane. Uma umiyane uluma inja enesifo, ubuye utheleleke nge-microfilariae. Ezinsukwini eziyi-10-14 ezilandelayo, lapho indawo ezungezile nezinga lokushisa kufaneleka futhi umiyane ungabulawa, i-microfilariae ikhula ibe izibungu ezithathelwanayo futhi zihlala emiyane. Izibungu ezithathelwanayo zingadluliselwa enja kuphela ngokuluma kuze kube yilapho umiyane uluma enye inja futhi.
Kuthatha izinyanga eziyisi-6-7 ukuthi izibungu ezithelelekayo zikhule zibe isibungu esidala. Ezindala ziyaphinda futhi, futhi ezinsikazi zidedela inzalo yazo egazini lenja futhi ukuze ziqedele wonke umjikelezo. Isikhathi sokuphila sezikelemu ezikhulile ezinjeni cishe iminyaka engu-5-7. Abesilisa bangaba ngu-10-15cm ubude kanti abesifazane bangama-25-30cm ubude. Ngokwesilinganiso, cishe zingu-15 izikelemu ezinjeni ezinalesi sifo, kuze kufike ku-250. Inani elithile lezikelemu ngokuvamile libhekwa ngomthwalo wezikelemu. Ngemishini yokuhlola igazi, ukuhlolwa kwe-antigen kungathola ngokunembile inani labantu abadala besifazane enjeni, futhi ukuhlolwa kwe-microfilaria kungaqinisekisa ukuthi akukhona nje abantu abadala kuphela kodwa nezibungu enjeni.
Kukhona izindinganiso ezithile zokuhlolwa kwe-heartworm e-United States: ukuhlolwa kokuqala kwe-heartworm kungaqala ngemva kokuba inja inezinyanga ezingu-7 ubudala; Abanikazi bezilwane ezifuywayo bakhohlwe okokugcina ukuvimbela isikelemu senhliziyo; Izinja zishintsha izidakamizwa ezivame ukusetshenziswa zokuvimbela izikelemu; Muva nje, ngihambise inja yami endaweni evamile yesikelemu senhliziyo; Noma inja ngokwayo ihlala endaweni evamile ye-heartworm; Ngemuva kokuhlolwa, ukuvimbela isifo senhliziyo kuzoqala.
Izimpawu nokuvimbela isifo sezikelemu ezinjeni
Ukuqina kwesifo senhliziyo kuhlobene ngokuqondile nenani lezikelemu emzimbeni (umthwalo wezikelemu), ubude besifo kanye nokuqina komzimba kwezinja. Lapho izikelemu eziningi emzimbeni, isikhathi eside sokutheleleka, inja iba namandla futhi inamandla, futhi izimpawu ziba sobala kakhulu. E-United States, isifo se-heartworm sihlukaniswa ngamabanga amane. Uma izinga liphezulu, lesi sifo siba sibi kakhulu.
Ibanga loku-1: izimpawu ezingabonakali noma ezithambile, njengokukhwehlela ngezikhathi ezithile.
Ibanga lesi-2: izimpawu ezithambile kuye kwezimaphakathi, njengokukhwehlela kanye nokukhathala ngemva komsebenzi omaphakathi.
Ibanga lesi-3: izimpawu ezibucayi kakhulu, njengokukhathala komzimba, ukugula, ukukhwehlela okungapheli kanye nokukhathala ngemva kokusebenza kancane. Izimpawu zokuphefumula kanzima nokuhluleka kwenhliziyo zivamile. Nge-filariasis yenhliziyo yebanga lesi-2 nelesi-3, izinguquko enhliziyweni nasemaphashini ngokuvamile zibonakala kuma-X-ray esifuba.
Ibanga lesi-4: elaziwa nangokuthi yi-vena cava syndrome. Umthwalo wezikelemu unzima kangangokuthi igazi eligeleza libuyela enhliziyweni livinjwa inqwaba yezikelemu emithanjeni yegazi. I-Vena cava syndrome isongela ukuphila. Ukuhlinzwa okusheshayo kwe-heartworm ukuphela kwendlela yokwelapha. Ukuhlinzwa kuyingozi. Ngisho noma kuwukuhlinzwa, izinja eziningi ezine-vena cava syndrome ekugcineni zizofa.
I-FDA igunyaze ukuthi i-melassomine dihydrochloride (amagama okuhweba i-immicide ne-diroban) ingajovwa ukwelapha isikelemu senhliziyo seBanga 1-3. Umuthi unemiphumela emibi emikhulu, futhi izindleko zokwelashwa sezizonke ziyabiza. Ukuhlolwa njalo, ama-X-ray kanye nemijovo yezidakamizwa kuyadingeka. Ukuze kukhishwe i-microfilariae, i-FDA igunyaze omunye umuthi, inzuzo eminingi yezinja (imidacloprid ne-moxikeding), okungukuthi "aiwalker".
E-United States, zonke izidakamizwa ezigunyazwe yi-FDA ukuvimbela isifo senhliziyo ziyimithi kadokotela, okuhlanganisa amaconsi namaphilisi omlomo afakwe esikhumbeni (Ewok, isilwane esikhulu esifuywayo, inja i-Xinbao, njll.), ngoba i-heartworm prophylaxis ngeke ibulale i-heartworm yabantu abadala, kodwa i-heartworm. ukuvimbela izinja ezingenwe i-heartworm yabantu abadala kungase kube yingozi noma kubulale. Uma i-microfilaria isegazini lenja, izinyathelo zokuvimbela zingase ziholele ekufeni kungazelelwe kwe-microfilaria, kubangele ukushaqeka okufana nokusabela kanye nokufa okungenzeka. Ngakho-ke, kuyadingeka ukwenza ukuhlolwa kokuvimbela isifo senhliziyo njalo ngonyaka ngaphansi kwesiqondiso nezeluleko zodokotela. I-"Worship Chong Shuang" iwukuxosha izinambuzane ezinomphetho obukhali. Ayiqondi ngokuqondile ama-microfilaria, kodwa izama ukugwema ukulunywa omiyane futhi inqamule ulayini wokudlulisela phakathi nendawo, okuphephe kakhulu ngempela.
Ngokuyisisekelo, ukuvimbela isifo senhliziyo kubaluleke kakhulu kunokwelashwa. Njengoba kungabonakala emjikelezweni wokukhula kwe-heartworm echazwe ngenhla, ukutshalwa komiyane kuyisixhumanisi esibaluleke kakhulu. Impilo ingaqinisekiswa kuphela ngokunqamula ukulunywa omiyane. Lokhu kuzoba ngcono kakhulu ezinja ezinezinwele ezinde, kuyilapho izinja ezinezinwele ezimfishane zidinga ukunakwa okwengeziwe.
