Among 500 barley kernels, tested singly, 1.8% (9 kernels) were positive for fecal streptococci. Among 800 malt kernels, tested singly by the same procedure, 68% (540 kernels) were positive for fecal streptococci. In unsulfured and sulfured malts, 67 and 68% of the kernels, respectively, were positive for these bacteria. Fecal streptococci were also isolated by an enrichment procedure from two brands of instant malted milk powder sold in supermarkets. Seventy randomly picked isolates from malts were identified to be fecal streptococci, belonging probably to more than one species.
在单独检测的500颗大麦粒中,1.8%(9颗)粪便链球菌检测呈阳性。通过相同程序单独检测的800颗麦芽粒中,68%(540颗)粪便链球菌检测呈阳性。在未硫化麦芽和硫化麦芽中,分别有67%和68%的麦粒这些细菌检测呈阳性。通过富集培养法还从超市销售的两个品牌的速溶麦乳精中分离出了粪便链球菌。从麦芽中随机挑选的70株分离菌被鉴定为粪便链球菌,可能属于不止一个物种。
