Ochwepheshe baseMelika baseNyuvesi yaseNorth Carolina bathola umphumela ongemuhle wokudla ilayisi abantu abaningi abangawucabangi ngisho nokucabanga ngawo. Umphumela ongalindelekile werayisi Ngokusho kososayensi, irayisi eliphekiwe lingaba yingozi emzimbeni. Uma igcinwe ekamelweni lokushisa isikhathi eside, akufanele uyidle - kulokhu, amathuba okuba nobuthi akhula kakhulu, ngokusho kwabacwaningi.
Amagciwane angatholakala elayisini, kusho ososayensi. Amagciwane ohlobo lwe-Bacillus cereus, angena emhlabathini, avame ukutholakala kuwo. Ngemva kokuhlola izindlela ezihlukene zokupheka ilayisi, abacwaningi bathola ukuthi ukwelapha ukushisa akuzange kubhubhise njalo ama-microorganisms ahlala elayisi. Uma izinhlamvu zebhaktheriya ezisinda ngemva kokupheka zingena emzimbeni womuntu ngokudla, lokhu kungabangela ukuwohloka okukhulu kwenhlalakahle. Umsebenzi wamabhaktheriya uhambisana nokukhululwa kwe-toxins, kuhlanganise ne-thermostable, ebangela izimpawu zobuthi. Ngokusho kochwepheshe, kungakapheli amahora amabili ngemva kokupheka, irayisi kufanele ifakwe esiqandisini - ngaphandle kwalokho ingozi yokufaka ubuthi izoba phezulu kakhulu.
“Izinhlamvu zebhaktheriya ziyakwazi ukuphila ukupheka ilayisi uma lijwayele ukugcinwa endaweni epholile uma seliphekiwe. Kulokhu, ama-spores akhula futhi anda, ”kusho ababhali bephrojekthi yesayensi.
