\u017diadne \u010dakanie na v\u00fdsledok PCR- testu, v\u010dely vo v\u00fdskume holandsk\u00fdch vedcov dok\u00e1zali identifikova\u0165 nakazen\u00fdch za sekundu<\/strong>. Rovnako r\u00fdchle s\u00fa aj psy. Vedci bio- veterin\u00e1rneho v\u00fdskumn\u00e9ho laborat\u00f3ria na jednej z holandsk\u00fdch univerz\u00edt vycvi\u010dili v\u010dely tak, aby rozpozn\u00e1vali pozit\u00edvne vzorky koronav\u00edrusu<\/strong>.<\/p>\n

Ak odhalili vzorku, dostali odmenu<\/strong><\/h3>\n

Vzorky vedci rozdelili do dvoch skup\u00edn, na infikovan\u00e9 v\u00edrusom Covid-19<\/strong> a neinfikovan\u00e9. V\u010dely boli vystaven\u00e9 pachu oboch vzoriek. Ak mali pred sebou pach infikovanej vzorky, dostali cukrov\u00fa vodu. Pri neinfikovanej zlo\u017eke, nedostali \u017eiadnu odmenu.<\/p>\n

V\u010dely sa nau\u010dili sp\u00e1ja\u0165 pach koronav\u00edrusu<\/strong> s\u00a0odmenou. Netrvalo dlho a\u00a0po tom, \u010do uc\u00edtili infikovan\u00fa vzorku, automaticky za\u010dali vystrkova\u0165 sos\u00e1ky, preto\u017ee predv\u00eddali, \u017ee dostan\u00fa vodu s\u00a0cukrom.<\/p>\n

Priebeh v\u00fdskumu pre agent\u00faru Reuters ozrejmil jeden z\u00a0\u00fa\u010dastn\u00edkov projektu, virol\u00f3g Wim van der Poel:\u201eV\u010dely medonosn\u00e9 sme zozbierali od v\u010del\u00e1rov, n\u00e1sledne sme ich umiestnili do postrojov. K pozit\u00edvnej vzorke pred nich d\u00e1me aj cukrov\u00fa vodu. A \u010do v\u010dely urobia? Roz\u0161\u00edria svoje sos\u00e1ky, aby si vzali cukrov\u00fa vodu.“<\/em><\/p>\n

Lacn\u00e1, ale testy pravdepodobne nenahrad\u00ed <\/strong><\/h3>\n

Ke\u010f\u017ee je met\u00f3da lacn\u00e1, mohla by by\u0165 pod\u013ea vedcov vyu\u017e\u00edvan\u00e1 najm\u00e4 v\u00a0krajin\u00e1ch s\u00a0nedostatkom testov.

\u201eJe to dobr\u00fd n\u00e1pad, ale rad\u0161ej by som robil testy pomocou klasick\u00fdch diagnostick\u00fdch n\u00e1strojov.

Tr\u00e9nuj\u00fa aj psov<\/strong><\/h3>\n

Hoci \u013eudsk\u00fd nos nedok\u00e1\u017ee zachyti\u0165 pach koronav\u00edrusu, ps\u00ed \u0148uf\u00e1k \u00e1no.

Pod\u013ea britsk\u00e9ho port\u00e1lu BBC a\u00a0ned\u00e1vneho v\u00fdskumu, psy spr\u00e1vne zachytili 88% nakazen\u00fdch.

Dokonca aj vtedy, ke\u010f osoba nemala \u017eiadne pr\u00edznaky alebo mala vo svojom tele iba ve\u013emi n\u00edzku hladinu v\u00edrusu. Av\u0161ak ani t\u00e1to met\u00f3da nie je \u00faplne spo\u013eahliv\u00e1.
