Nemishonga Universal kuti nemishonga - kuguma kwemazuva ano?

Maererano nenyanzvi, nyika yava pedyo "munguva postantibiotikov". Nokukurumidza zvakajairika Zvirwere anogona zvakare kuva ngozi kune vanhu. Izvi zvichaitika kana kuitika mberi. Ngozi nemavhairasi uye mabhakitiriya akava kuramba zvinodhaka, izvo makore 100 apfuura aiva zvokurapa budiriro. Kana kuti nguva anouya, zvichaita zvinozondiomera kunzwisisa maoparesheni. Varwere vachatongerwa chihombe ngozi pamwe nhengo kuisirwa, vagari kutsiva uye mishonga. Under norufu zvichaita akashaya kuberekwa vacheche, kugara uremu chaihwo incubators. Sezvaunogona kuona, "nenguva postantibiotikov" anogona kugumisa mushonga ano muchimiro nayo Parizvino waanogara.

Sei vanombofunga Zvirwere sei nemishonga?

dambudziko iri wakaziviswa muna April gore rakapera, mutungamiriri World Health Organization, Dr. Margaret Chan. Nyanzvi dzakawanda mune zvokurapa kunge vatotenderana kuti mutant mabhakitiriya anogona kuva dambudziko №1 kuti utano munyika yose. Nei vamwe zvirwere havachaoni kupindura mishonga? Pamwe hatina chikonzero vakurumidze kutya?

Izvi kunoratidzwa mukanyiwa pakutsvakurudza: zvinodhaka kuti tinoshandisa kuti kurapwa kwezvirwere zvinotapuriranwa, zvishoma nezvishoma kubudirira kwayo. Kana tikaramba kushandisa inonyatsozivikanwa zviyero, pakupedzisira, hapana mushonga havazokwanisi kukunda mabhakitiriya. Zvinosuruvarisa, mushonga kamwe yakatowedzera zvakaipa njanji. Kubudirira inorwisa mabhakitiriya asingadi kuderedzwa chete nyaya kana ivo haripo.

Sezvo hwedu zvinochinja?

Zvanzi Kumutungamiriri Muzinda nemishonga pa Emory University, Dr. Devid Vays: "Izvi zvichachinja zvose hwedu kwakajairika mupfungwa. Funga nezvokuti vanhu vachakandwa kure shure mumazuva apo kunyange chironda chidukuduku aigona kumutsa rufu. "

Chii chingaitwa kudzivisa hutano apocalypse?

Takaita akaronga kwakakwidibira chaizvo mufananidzo. Zvisinei, tine zvimwe akanaka. Nyika anozivikanwa nezvedambudziko iri uye ari nechekare kutanga kutora matanho pane chemhando chechetere. Kune vazhinji private uye voruzhinji masangano uyewo vanhu vanotsigirwa ne hurumende dzakabudirira dziri kushanda zvakaoma kudzivisa yakaipisisa kuitika nokuda yose vanhu.

Constant kuramba nemishonga hazvigoni kudziviswa

Zvinosuruvarisa, zvinhu hazvisi nyore. Pasinei nokuedza zvakanakisisa pfungwa yesayenzi, utachiona kare ane chombo simba paaiitirana ichi. Kukwanisa ichi kutanga zvigare zviri nedanho shanduka. Uye kana pakanga pasina nemishonga, paisazova kuramba kwavari. Ndizvo hunhu mabhakitiriya. Tinogona kuona izvi pane muenzaniso staph utachiwana. Kare, zviri nyore kubatwa penicillin. Asi mutated utachiona nhasi, uye tine MRSA shanduro, umo muzana chete gumi vakasara kubva yapfuura staph utachiona. Zvino, kuti penicillin ndiyo chombo zvachose pakurwisa mutated utachiona. Sezvo kuongorora vatsva, vanhu vaviri kubva ose zana vari vatakuri kwemabhakitiriya MRSA, kana methicillin nemishonga anonzi Staphylococcus aureus.

Sei kurwisa?

Sezvakangoita vanhu, mabhakitiriya vane DNA. Kungofanana nevanhu, iyo macromolecules ose deoxyribonucleic asidhi dzingasiyana uye muzviise pasi kunotouraya. Kana varwere vanoshandisa mishonga yokuuraya utachiona, mune zvimwe zviitiko, nemaziso nomuzvarirwo mutate, kuchinja murwiyo kuitira kuti mishonga simba. Mabhakitiriya aya vane wakawedzera wokurarama uye hunogona kutapukira kubva chisikwa mumwe.

Yakaomesesa chikamu izvi ndechokuti nemishonga tusingaoneki vangadyawo chikamu DNA zvavo nedzimwe utachiona. Zvino vanhu nemhuka azara dzakazadza akasiyana mhando unicellular. Kunyange kana munhu kamwe chete muupenyu hwake hwamborohwa nemishonga, uye okuva vaigona mutate kuti mugumo hwake ichange iine dzakachinjwa utachiona kuti hauna dambudziko pakupararira.

In mhedziso

Uye vanhu vari kuedza neutralize chinouraya tusingaoneki kushandisa zvinodhaka, yakawanda nzira nokushandiswa, zvikuru mikana iripo nokuda kukura itsva kwemabhakitiriya Gene. Kubva izvi anotevera mhedziso imwe chete: isu kuchangoita kushandisa musoro inorwisa mabhakitiriya vanenge zvashata. Chete nenzira iyi tinogona kuwana utachiona zvombo ari kurwisa.
