Matenda atsopano owopsa omwe amayamba ndi kachilombo komwe kamayambitsa matenda a ng'ombe, matendawa amatchedwang'ombe encephalitis. Chifukwa chomwe sindimatchula kuti kachilomboka ndi chiyani chifukwa asayansi samadziwabe kuti ndi chiyani.
Pali ziphunzitso zambiri za mtundu wa kachilombo kameneka, ndipo ambiri mwa iwo ndi prion - chinthu chodabwitsa cha mapuloteni omwe amatha kusintha mawonekedwe ake, ndiye kuti ndi mchenga wopanda moyo, ndiye kuti mwadzidzidzi amakhala. chinthu chamoyo, chogwira ntchito ndi chakupha. Koma palibe amene akudziwa kwenikweni chomwe chiri. Asayansi sadziwa nkomwe momwe ng'ombe zimatengera kachilomboka. Ena amanena kuti ng’ombe zimagwidwa ndi matenda a nkhosa zomwe zili ndi matenda ofanana, ena sagwirizana ndi maganizo amenewa. Chokhacho chomwe palibe mkangano ndi momwe bovine encephalitis imafalikira. Matendawa ndi odziwika ku UK chifukwa, m'mikhalidwe yachilengedwe, ng'ombe zimadya ndikudya udzu ndi masamba okha, ndipo nyama zaulimi zimadyetsedwa ndi zidutswa zophwanyidwa za nyama zina, pakati pawo zimabwera mu ubongo momwe kachilomboka kamakhala. Choncho, matendawa akufalikira. Matendawa sanachiritsidwebe. Imapha ng'ombe ndipo imatha kupha nyama zina monga amphaka, mink, ngakhale nswala zodyetsedwa ndi ng'ombe yoipitsidwa. Anthu ali ndi matenda ofanana omwe amatchedwa Matenda a Cretzvelt-Jakob (CJD). Panali mikangano yambiri komanso mkangano wokhudza ngati matendawa ndi ofanana ndi matenda a bovine encephalitis komanso ngati anthu angadwale ndi kudya nyama ya ng'ombe yomwe ili ndi kachilomboka. Patatha zaka 1986 kuchokera pamene matenda a ng’ombe anatulukira m’chaka cha XNUMX, akuluakulu a boma la Britain ananena kuti anthu sangatenge matendawa ndiponso kuti CJD ndi matenda osiyana kotheratu - choncho ng’ombe imatha kudyedwa bwinobwino. Pofuna kupewa ngozi, iwo anamaliza kunena kuti ubongo, tiziwalo timene timatulutsa timadzi tambirimbiri, ndiponso timagulu ta minyewa timene timadutsa mumsana siziyenera kudyedwa. Izi zisanachitike, nyama yamtunduwu inkagwiritsidwa ntchito kuphika burger и mapepala. Pakati pa 1986 ndi 1996, ng'ombe za ku Britain zosachepera 160000 zinapezeka kuti zili ndi bovine encephalitis. Nyama zimenezi zinawonongedwa ndipo nyamayo sinali kudya. Komabe, wasayansi wina akukhulupirira kuti ng’ombe zoposa 1.5 miliyoni zinali ndi kachilomboka, koma matendawa sanasonyeze zizindikiro. Ngakhale zidziwitso za boma la UK zikuwonetsa kuti ng'ombe iliyonse yomwe imadziwika kuti ikudwala, pali ng'ombe ziwiri zomwe zimadziwika kuti zilibe matenda. Ndipo nyama ya ng’ombe zonse zodwala zimenezi inali chakudya. Mu March 1996, boma la UK linakakamizika kuulula. Inanena kuti n’kutheka kuti anthu angathe kutenga matendawa ndi ng’ombe. Kumeneku kunali kulakwitsa koopsa chifukwa anthu mamiliyoni ambiri anadya nyama yowonongeka. Panalinso zaka zinayi zomwe pambuyo pake opanga zakudya adaletsedwa kugwiritsa ntchito ubongo и mitsempha, pamene zidutswa za nyama zomwe zinali ndi kachilombo koopsazi zinkadyedwa nthawi zonse. Ngakhale boma litavomereza kulakwitsa kwake, likuumirirabe kuti tsopano zitha kunenedwa ndi udindo wonse kuti mbali zonse zowopsa za nyama zimachotsedwa ndipo chifukwa chake, ndibwino kudya ng'ombe. Koma pokambitsirana patelefoni, wapampando wa bungwe loona za nyama zakutchire la Meat Control Commission, lomwe ndi bungwe loyang’anira malonda a nyama yofiyira mdziko muno, adavomereza kuti. Bovine encephalitis virus imapezeka mumitundu yonse ya nyama, ngakhale nyama zowonda. Kachilombo kameneka kakhoza kupezeka pamlingo wochepa, koma palibe amene anganene motsimikiza kuti zotsatira za kudya pang'ono kachilombo ka HIV ndi nyama zidzakhala zotani. Zomwe tikudziwa ndizakuti zimatenga zaka khumi mpaka makumi atatu kuti zizindikiro za bovine encephalitis, kapena CJD, ziwonekere mwa anthu, ndipo matenda amenewa nthawi zonse amapha chaka chimodzi. Mudzasangalala kumva kuti sindikudziwapo mlandu umodzi wokha wakufa ndi poizoni wa karoti.
