Apho kukho iingcongconi, kusenokubakho intshulube yentliziyo
Intliziyoisifo sisifo esiyingozi kwizilwanyana zasekhaya zokonga. Ezona zilwanyana zasekhaya ezosulelekileyo zizinja, iikati kunye neeferrets. Xa umbungu ukhula, uhlala entliziyweni, emiphungeni nakwimithambo yegazi yezilwanyana. Xa umbungu ukhulile kwaye ubangele izifo, kuya kubakho isifo esibi semiphunga, ukuphelelwa yintliziyo, ukwenzakala kunye nokufa kwamanye amalungu.
I-Heartworm yintsholongwane engaqhelekanga. Ayinakudluliselwa ngokuthe ngqo phakathi kwezinja, iikati kunye neekati, izinja kunye neekati. Kufuneka isasazwe ngomthetheleli. EUnited States, isifo se-heartworm sisasazeka kuwo onke amazwe angama-50, kodwa ubukhulu becala sigxile kwiGulf of Mexico, iMississippi River Basin nakwezinye iindawo, kuba zininzi iingcongconi kwezi ndawo. Kukho iimeko zosulelo kuzo zonke iindawo zelizwe lethu, kwaye izinga losulelo kwezinye iindawo lingaphezulu kwama-50%.
Izinja ngowona mkhosi uphezulu wentliziyo, oku kuthetha ukuba yi-heartworm kuphela ehlala ezinjeni inokukhwelana kwaye ivelise inzala. Ngokukodwa, abantu abayi kosulelwa yiheartworm evela kwizilwanyana zasekhaya. Kuphela kwiimeko ezinqabileyo, abantu banokosulelwa yi-heartworm emva kokulunywa ziingcongconi ezosulelekileyo. Nangona kunjalo, ngenxa yokuba abantu bengengomsingathi, imibungu idla ngokufa ngaphambi kokuba ifudukele kwimithambo yentliziyo nemiphunga.
Ukukhula kwentliziyo kwizinja
I-heartworm yabantu abadala ihlala kwi-cardiovascular system yezinja. Abantu abadala abangamabhinqa bazala i-microfilariae, kwaye amaqanda ageleza kwiindawo ezahlukeneyo ngegazi. Nangona kunjalo, ezi microfilariae azikwazi ukuqhubeka zikhula, kwaye kufuneka zilinde ukufika kweengcongconi. Xa ingcongconi iluma inja enesifo, iphinda yosulelwe yi-microfilariae. Kwiintsuku eziyi-10-14 ezizayo, xa indawo engqongileyo kunye neqondo lokushisa lifanelekile kwaye i-mosquito ingabulawa, i-microfilariae ikhula ibe yimibungu esosulelayo kwaye ihlala kwi-mosquito. Imibungu eyosulelayo inokudluliselwa kuphela kwinja ngokuluma de ingcongconi ilume enye inja kwakhona.
Kuthatha iinyanga ezi-6-7 ukuba imibungu eyosulelayo ikhule ibe yintliziyo yabantu abadala. Ezindala ziphinda zikhwelane, zize iimazi zikhuphe inzala yazo egazini lenja kwakhona ukuze zigqibezele wonke umjikelo. Ubomi be-heartworms abadala kwizinja malunga neminyaka emi-5-7. Iinkunzi zimalunga ne-10-15cm ubude kwaye iimazi ziyi-25-30cm ubude. Ngokwe-avareji, kukho malunga ne-15 ye-heartworms kwizinja ezosulelekileyo, ukuya kuma-250. Inani elithile leentshulube ngokubanzi ligwetywa ngumthwalo weentshulube. Ngezixhobo zokuvavanya igazi, uvavanyo lwe-antigen lunokubona ngokuchanekileyo inani labantu abadala ababhinqileyo kwinja, kwaye uvavanyo lwe-microfilaria lunokuqinisekisa ukuba akukho bantu abadala kuphela kodwa kunye nemibungu kwinja.
Kukho imigangatho yokuhlola i-heartworm e-United States: ukuhlolwa kokuqala kwe-heartworm kunokuqala emva kokuba inja ineenyanga ezi-7 ubudala; Abanini bezilwanyana zasekhaya balibale ixesha lokugqibela ukukhusela intliziyo; Izinja zitshintsha amayeza okuthintela iintshulube ezisetyenziswa ngokuqhelekileyo; Kungekudala, ndathatha inja yam kwindawo eqhelekileyo ye-heartworm; Okanye inja ngokwayo ihlala kwindawo eqhelekileyo ye-heartworm; Emva kovavanyo, uthintelo lwe-heartworm luya kuqala.
Iimpawu kunye nokuthintela usulelo lwe-heartworm kwizinja
Ubunzima besifo sentliziyo bunxulumene ngokuthe ngqo nenani leentshulube emzimbeni (umthwalo weentshulube), ubude bosulelo kunye nokufaneleka komzimba wezinja. Iintshulube ezininzi emzimbeni, ixesha lokusuleleka ixesha elide, inja iyasebenza kwaye yomelele, kwaye iimpawu zibonakala ngakumbi. EUnited States, isifo sentliziyo sahlulwe saba ngamabanga amane. Okukhona ibakala liphezulu, kokukhona isifo sibi kakhulu.
IBanga loku-1: iimpawu ezingabonakaliyo okanye ezibuthathaka, ezifana nokukhohlela ngamaxesha athile.
IBanga lesi-2: iimpawu ezisezantsi ukuya kweziphakathi, ezifana nokukhohlela ngamaxesha athile kunye nokudinwa emva komsebenzi ophakathi.
IBanga lesi-3: iimpawu ezimandundu ngakumbi, njengokudinwa komzimba, ukugula, ukukhohlela okuzingileyo kunye nokudinwa emva kokusebenza kancinci. Iimpawu zobunzima bokuphefumla kunye nokusilela kwentliziyo zixhaphakile. Kwibanga lesi-2 kunye nelesi-3 i-cardiac filariasis, utshintsho entliziyweni nakwimiphunga ludla ngokubonwa kwi-X-ray yesifuba.
IBanga lesi-4: ekwabizwa ngokuba yi-vena cava syndrome. Umthwalo weentshulube unzima kangangokuba igazi elibaleka libuyela entliziyweni livalwe linani elikhulu leentshulube kwimithambo yegazi. I-Vena cava syndrome ibeka ubomi esichengeni. Uqhaqho olukhawulezileyo lwe-heartworm lolona khetho lonyango. Utyando luyingozi. Nangona utyando, ezininzi izinja ezine-vena cava syndrome ziya kufa ekugqibeleni.
I-FDA ivume ukuba i-melassomine dihydrochloride (amagama orhwebo i-immicide kunye ne-diroban) inokutofwa ukunyanga i-heartworm yeBakala 1-3. Ichiza lineziphumo ebezingalindelekanga ezinkulu, kwaye ixabiso lonyango lilonke liyabiza. Iimvavanyo zarhoqo, ii-X-reyi kunye nokutofwa kweziyobisi ziyafuneka. Ukususwa kwe-microfilariae, i-FDA ivume elinye ichiza, inzuzo eninzi kwizinja (imidacloprid kunye ne-moxikeding), eyile "aiwalker".
EUnited States, onke amachiza avunyiweyo yi-FDA ukukhusela i-heartworm ngamachiza achazwe ngugqirha, kubandakanywa amaconsi kunye neepilisi zomlomo ezifakwe esikhumbeni (Ewok, isilwanyana esikhulu, inja i-Xinbao, njl.), kuba i-heartworm prophylaxis ayiyi kubulala i-heartworm yabantu abadala, kodwa i-heartworm. uthintelo lwezinja ezosulelwe yiheartworm yabantu abadala lunokuba yingozi okanye lubulale. Ukuba i-microfilaria isegazini lenja, imilinganiselo yokuthintela inokukhokelela ekufeni ngesiquphe kwe-microfilaria, kubangele ukothuka okufana nokusabela kunye nokufa okunokwenzeka. Ngoko ke, kuyimfuneko ukwenza uvavanyo lokuthintela isifo senhliziyo rhoqo ngonyaka phantsi kwesikhokelo kunye neengcebiso zoogqirha. "Nqula iChong Shuang" yintsholongwane egxotha inambuzane ebukhali. Ayijongi ngqo kwi-microfilariae, kodwa izama ukunqanda ukulunywa yingcongconi kwaye inqumle intambo yosulelo ukusuka embindini, eneneni ekhuseleke kakhulu.
Ngokusisiseko, ukuthintelwa kwesifo sentliziyo kubaluleke ngakumbi kunonyango. Njengoko kunokubonwa kumjikelezo wokukhula kwentliziyo echazwe ngasentla, ukulinywa kweengcongconi lelona khonkco libalulekileyo. Impilo inokuqinisekiswa kuphela ngokunqunyulwa kwengcongconi. Oku kuya kuba ngcono kakhulu kwizinja ezineenwele ezinde, ngelixa izinja ezimfutshane zifuna ukuqwalaselwa ngakumbi.
