Chirwere chitsva chinotyisa chinokonzerwa nehutachiona humwe hunokonzera chirwere chemombe, chirwere ichi chinonzibovine encephalitis. Chikonzero ini ndisatsanangure kuti hutachiona chii nekuti masayendisiti haasati aziva kuti chii.
Kune akawanda dzidziso pamusoro pemhando yehutachiona, uye inonyanya kuzivikanwa ndeye prion - chinhu chinoshamisa cheprotein chinogona kushandura chimiro chayo, yobva yaita tsanga isina hupenyu yejecha, yobva yangoerekana yavapo. chinhu chipenyu, chinoshanda uye chinouraya. Asi hapana anonyatsoziva kuti chii. Vesainzi havatombozivi kuti mombe dzinowana sei utachiona uhu. Vamwe vanoti mombe dzinobatwa nehwai dzine chirwere chakadai, vamwe havabvumirani nemafungiro aya. Chinhu chimwe chete chisina kupokana ndechekuti bovine encephalitis inotapuriranwa sei. Chirwere ichi chinozivikanwa neUK nekuti, mumamiriro ezvinhu echisikigo, mombe dzinofura uye dzinodya uswa nemashizha chete, uye mhuka dzepurazi dzinodyiswa nezvidimbu zvakapwanyika zvedzimwe mhuka, pakati padzo dzinouya nehuropi hunogara hutachiona uhu. Nokudaro, chirwere ichi chiri kupararira. Chirwere ichi hachisati charapika. Inouraya mhou uye inogona kuuraya kune dzimwe mhuka dzakadai sekitsi, mink, uye kunyange nondo dzakadyiswa nyama yemombe ine utachiona. Vanhu vane chirwere chakafanana chinonzi Chirwere cheCretzvelt-Jakob (CJD). Pakange paine makakatanwa akawanda pamwe nekukakavadzana pamusoro pekuti chirwere ichi chakangofanana here nerebovine encephalitis uye kuti vanhu vangarwara here nekudya nyama yemombe ine utachiona. Makore gumi mushure mekunge bovine encephalitis yawanikwa muna 1986, vakuru vakuru vehurumende yeBritain vakati vanhu havagone kubata chirwere ichi uye kuti CJD chirwere chakasiyana zvachose - saka nyama yemombe inogona kudyiwa zvisina njodzi. Senzira yekuzvidzivirira, vakapedzisira vataura kuti uropi, mamwe maglands, uye tsinga dzetsinga dzinofamba nemuzongoza dzaisafanira kudyiwa. Izvi zvisati zvaitika, rudzi urwu rwenyama rwaishandiswa pakubika burgers и pie. Pakati pa1986 na1996, mombe dzeBritain dzinosvika 160000 dzakawanikwa dziine bovine encephalitis. Mhuka idzi dzakaparadzwa, uye nyama yacho haina kushandiswa pakudya. Zvisinei, mumwe musayendisiti anotenda kuti mombe dzinopfuura mamiriyoni 1.5 dzakabatwa nechirwere ichi, asi chirwere chacho hachina kuratidza zviratidzo. Kunyangwe data yehurumende yeUK inoratidza kuti pamombe yega yega inozivikanwa kuti inorwara, kune mombe mbiri dzinozivikanwa kuti hadzina chirwere chinozivikanwa. Uye nyama yemombe dzose idzi dzine chirwere chaishandiswa pakudya. Muna Kurume 1996, hurumende yeUK yakamanikidzwa kureurura. Yakataura kuti zvinokwanisika kuti vanhu vanogona kubata chirwere ichi kubva kumombe. Uku kwaive kukanganisa kukuru nekuti mamiriyoni evanhu akadya nyama ine utachiona. Paivawo nenhambo yemakore mana mushure mokunge vagadziri vezvokudya vakarambidzwa kushandisa ubongo и nerve, nepo idzi nhindi dzenyama dzine utachiona hwakanyanya dzaigara dzichidyiwa. Kunyangwe mushure mekunge hurumende yabvuma kukanganisa kwayo, ichiri kusimbirira kuti iko zvino zvinogona kutaurwa zvine mutoro wakazara kuti zvikamu zvese zvine ngozi zvenyama zvinobviswa uye nekudaro, zvakachengeteka kudya nyama yemombe. Asi muhurukuro parunhare, sachigaro webazi rezvezvipfuyo veMeat Control Commission, sangano renyika rinoona nezvekutengeswa kwenyama tsvuku, vakabvuma kuti. bovine encephalitis virus inowanikwa mumhando dzose dzenyama, kunyange yakaonda steaks. Hutachiona uhu hunogona kuwanikwa mudiki, asi hapana anogona kutaura aine chokwadi kuti mhedzisiro yekudya dhamu diki rehutachiona uhu nenyama. Chatinongoziva ndechekuti zvinotora makore gumi kusvika makumi matatu kuti zviratidzo zvebovine encephalitis, kana CJD, zvioneke muvanhu, uye zvirwere izvi zvinogara zvichiuraya mukati megore. Muchafara muchinzwa kuti hapana kana nyaya imwe chete yandinoziva yekufa necarrot poison.
