Chinangwa chechidzidzo ichi chaiva genetic characterization uye kuchengetedzwa kwekuongorora kwe 129 Enterococcus isolates yakawanikwa kubva muwaini iri pasi pemalolactic fermentation.Genetic characterization ne randomly amplified polymorphic DNA-PCR yakaratidza 23 genotypes.25 isolates inomiririra ese genotypes akaonekwa seEnterococcus faecium nemhando-yakananga PCR uye akayedzwa kurwisa kwemishonga inorwisa mabhakitiriya, kuvapo kwemajini ehutachiona uye kugona kweaminobiogenic, zvese mudecarboxylase yepakati newaini.The aminobiogenic simba muwaini yakaongororwa muhupo (assay 1) uye kusavapo (assay 2) yeOenococcus oeni CECT 7621. Resistance to tetracycline, cotrimoxazol, vancomycin uye teicoplanin yakaratidzwa ne96% yezvipembenene, asi hapana chimwe chazvo chakabatwa. virulence majini.Ese emhando dzakabata tyrosine decarboxylase (tdc) gene, nepo 44% yaive yakanaka kune tyramine mune decarboxylase medium.Zvishanu chete kubva mumhando makumi maviri neshanu zvakapona muwaini mushure memazuva manomwe ekunyudzwa, uye apo concence trations yebiogenic amines muwaini yakatemerwa neHPLC, iwo mawaini chete maive nemhando shanu dzakasara dzaive nebiogenic amines.Histamine, putrescine uye cadaverine zvakaonekwa muwaini kubva kune zvose zviedzo, kunyange zvazvo kuwedzera kwaive kwakakwirira mukuedza 2. Tyramine uye phenylethylamine zvakaonekwa chete pasina O. oeni.Tsvagiridzo iyi inopa ruzivo rwekuchengetedza zvinhu zve enterococci zvine chekuita nekugadzira waini.
