Kuwuluka CC - chotengera cha nthenda yomwe imapha

Za ntchentche owopsa amadziwika kuti aliyense wa sukulu. CC Ntchentche amakhala Africa. Ndipo tsopano, zaka 150 ndi mantha anthu ndi nyama wamba. M'madera ena, anthu kuponya m'minda chonde ndi kupita ku malo ena. M'mayiko izi palibe bloodsuckers woipa kuposa kuwuluka CC. Kodi iye wolakwa, ngati kwenikweni si zimatulutsa poizoni yake? Chifukwa chachikulu imfa ya anthu masauzande - zoopsa tiziromboti trypanosomes, limene likutengera tizilombo.

Kodi ntchentche CC

Mawonekedwe mwachizolowezi, pafupifupi ngati ntchentche wamba kwambiri, alinso ake mbali mwini chosiyana. Pa mutu wake pali Zikuluzikulu yaitali, amene amalola akazi kuluma kudzera pakhungu la anthu ndi nyama ndi kudya magazi. mapiko translucent kuti amagwa mphwayi boma mosabisa pamene ntchentche yekha. Pansi pa tizilombo imvi mimba, ndi pamwamba - chikasu, anayi kotenga mdima mikwingwirima zili pa chifuwa chofiira. The wamkulu ntchentche CC, woimiridwa ndi chithunzi pamwambapa, moyo kwagona 10 mphutsi, umene kugwa pa nthaka, burrow ndi pupate kwa maola angapo.

Kodi inu kachilomboko

Ndondomeko kuipitsidwa mosalephera, ngati IC kuwuluka kamodzi anadya onyamula magazi trypanosomiasis (kapena "kaodzera"). Malinga ndi asayansi, mlandu antelopes zakuthengo ndi nyama zina zomwe zimakhala mu magazi a tiziromboti izi. Ndi nyama okha ku matenda simufa. Kaodzera sakhala pomwepo. Choyamba, wodwala akumva kufooka, kutopa, kusintha kumachitika mu chapakati mantha dongosolo. Munthu wotopa zambiri wotaya chikumbumtima ndipo igwera mu tulo semiconscious, pali zisindikizo pa thupi lake, meningoencephalitis chitukuko, munthu amafa chifukwa. Ndipo iwo amafa osati anthu zakwawoko. Ambiri alendo atabwerera ku Africa anapezeka ndi kachilombo ndi kaodzera.

Chifukwa ng'ombe kuwuluka IC si zochepa chiopsezo. Ndi imfa ya matenda kutsogolera nyama - Atamuloza, chomwenso ndi odza ndi tizilombo izi kukhetsa mwazi. Malinga ndi ziwerengero chisoni za kambalame zimafalitsa zimauluka kulumidwa amafa chaka 3 miliyoni ng'ombe.

Asayansi kufunafuna njira

Anthu a Africa ndi Australia, kumene bloodsucker wamoyo, kuyembekezera chipulumutso ku ngozi. Koma tsiku palibe mankhwala "kaodzera" kapena njira kuwononga za kambalame zimafalitsa ntchentche. Trypanosomes zinthu azitengapo kwambiri mu thupi la munthu, iwo mutate ndi mutate, choncho n'zosatheka kupha masinthidwe onse mankhwala umodzi. Aonongedwa majeremusi zingapo, ndipo ena kupitiriza umoyo wawo.

Mkulu ziyembekezo asayansi anaika njira yatsopano kwa kuchepetsa chiwerengero cha ntchentche za kambalame zimafalitsa. Kuwuluka akazi ndi mwamuna kamodzi kokha moyo. Kudziwa mbali zimenezi, ofufuza anaganiza kumasula m'tchire mamiliyoni amuna chosawilitsidwa. Kuti tichite zimenezi, iwo mwapadera zimaŵetedwa ndi irradiated ndi cheza. Female, wophatikizidwa kamodzi, kuti kudzilola mwamuna wina, komanso kubereka sadzatha. njira imeneyi, malinga ndi akatswiri, adzachotsa zonyamulira za matenda oopsa. Ndipo pafupi zaka zingapo kuwuluka CC idzapita ku nkhope ya dziko.
