<prompt> Pfupisa nyaya yacho: Unonakidzwa nokunyura mugungwa uye unotarisana nengozi yokurwara nemabhakitiriya asingadi mishonga inorwisa mabhakitiriya. Vanoshambira uye vanoita surfing ndivo vanonyanya kubatwa nechirwere cheE.coli sezvo vachiwanzomedza mvura yakasvibiswa, kwakaratidza kudaro imwe ongororo. Masayendisiti paYunivhesiti yeExeter akanyevera nezvengozi yacho pashure pokuongorora mashoko akaunganidzwa pamhenderekedzo dzegungwa muEngland neWales muna 2012. Vakaisa pfungwa dzavo pamutsara webhakitiriya yeE. coli isingagoni kurwisa rudzi runokosha rwemishonga inorwisa mabhakitiriya inonzi cephalosporins yechitatu-chizvarwa, kana kuti 3GCs. Vanoshambira uye vanoita surfing ndivo vanonyanya kubatwa nechirwere cheE.coli sezvo vachikwanisa kumedza mvura yakasvibiswa, kutsvakurudza kwakaratidza kudaro. Mutungamiriri weongororo Dr. William Gaze akati: Tinoziva zvishomanene zvikuru pamusoro penzira iyo mhoteredzo yomusikirwo inogona kuparadzira nayo mabhakitiriya asingadziviriri mishonga inorwisa mabhakitiriya kuvanhu, kana kuti nzira yatinogona kuratidzirwa nayo kuutachiona uhwu inogona kutapura nayo utano. Vanhu vanotapurirwa utachiona husingaurayiwi nemishonga nenzira dzakasiyana-siyana, nokuonana nevanhu, nezvokudya uye nokufamba munyika dzakasiyana-siyana. Tsvakurudzo yedu inosimbisa kushandiswa kwokuvaraidza kwemvura dzomumhenderekedzo yegungwa senzira yokuwedzera yokuratidzirwa. Nevanhu vane mamiriyoni vanoshanyira mahombekombe muEngland neWales gore roga roga, pane ngozi yokuti vanhu vanodya E. coli isingagamuchirwi ne3GC uye zvinoratidzika sokuti kusangana nevashandisi vemvura nemabhakitiriya ose asingagamuchirwi kungava kwakanyanya. Kana uchifarira kunyura mugungwa uye uchiisa pangozi yokuwana utachiona hweE.coli hunooneka pamufananidzo husingaurayiwi nemishonga inorwisa mabhakitiriya inokosha. Munyu uri mumvura yegungwa unozivikanwa kuti unouraya mamwe mabhakitiriya, asi kwete ose. Kunyange zvazvo 0,12 muzana chete yeE.coli yakawanikwa mumvura dzomumhenderekedzo yegungwa uye nzizi dzinoyerera dzichienda kumhenderekedzo dzegungwa dzaiva dzorudzi urwu, vatsvakurudzi vakati izvi zvakanga zvakakwana kuratidza ngozi inogona kuvapo. Kuongorora kwacho, kwakabudiswa mumagazini inonzi Environment International, kwakaratidza kuti ngozi yokurohwa nemhepo yaiva nechokuita nounhu hwemvura pamhenderekedzo chero ipi zvayo. Vanotsvakurudza vakati izvi zvakaratidza kukosha kweEU Bathing Water Directive, iyo inovavarira kuvimbisa mitemo yakanaka yemvura, asi vakawedzera kuti vanhu havafanire kudzingwa...  <response>: Vanoshambira uye vanoita surfing ndivo vari pangozi huru yokubata utachiona hweE.coli, inodaro fundo yacho. Izvi imhaka yokuti kazhinji vanomedza mvura yakasvibiswa. Masayendisiti eUniversity of Exeter akanyevera nezvengozi pashure pokuongorora mashoko.
