Cholinga cha kafukufukuyu chinali mawonekedwe a chibadwa ndi kuwunika kwa chitetezo cha 129 Enterococcus isolates zopezedwa kuchokera ku vinyo yemwe amawotchera malolactic.Mawonekedwe a chibadwa opangidwa mwachisawawa polymorphic DNA-PCR amawonetsa 23 genotypes.25 zodzipatula zoimira mitundu yonse ya ma genotypes zidadziwika kuti Enterococcus faecium ndi PCR yeniyeni yamitundu ndikuyesa kukana kwa maantibayotiki, kukhalapo kwa majini a virulence ndi mphamvu ya aminobiogenic, onse mu sing'anga ya decarboxylase ndi vinyo.Mphamvu ya aminobiogenic mu vinyo idawunikidwa pamaso (kuyesa 1) ndi kusowa (kuyesa 2) kwa Oenococcus oeni CECT 7621. Kukaniza kwa tetracycline, cotrimoxazol, vancomycin ndi teicoplanin kunawonetsedwa ndi 96% ya zovutazo, koma palibe mmodzi wa iwo amene anakhudzidwa chibadwa cha ma virus.Mitundu yonseyi inali ndi jini ya tyrosine decarboxylase (tdc), pomwe 44% inali yabwino kwa tyramine mu sing'anga ya decarboxylase.Ndi mitundu isanu yokha mwa mitundu 25 yomwe idapulumuka mu vinyo patatha masiku asanu ndi awiri a makulitsidwe, ndipo pamene ma biogenic amines mu vinyo adatsimikiziridwa ndi HPLC, mavinyo okhawo omwe mitundu isanu yomwe idatsala idachitika inali ndi ma biogenic amines.Histamine, putrescine ndi cadaverine zinapezeka mu vinyo kuchokera ku mayesero onse awiri, ngakhale kuti zowerengera zinali zapamwamba mu kuyesa 2. Tyramine ndi phenylethylamine zinadziwika pokhapokha O. oeni.Kafukufukuyu amathandizira kudziwa zachitetezo cha enterococci chokhudzana ndi kupanga vinyo.
