A total of 91 food and environmental samples were examined for the presence of salmonellae using a commercially available enzyme immunoassay kit (EIA) and a conventional culture technique. A 78% agreement was obtained, but reexamination of culture-negative, EIA-positive samples gave agreement of 86%. The problem of comparing EIA and culture results is discussed. A partially selective pre-enrichment broth was tested in 37 samples and gave better EIA ratios. Artificially contaminated cooked foods gave 100% agreement.
使用市售酶免疫分析试剂盒(EIA)和传统培养技术,共检测了91份食品和环境样本中的沙门氏菌。两种方法的结果一致性为78%,但对培养阴性、EIA阳性的样本进行重新检测后,一致性达到了86%。文中讨论了比较EIA和培养结果的问题。在37份样本中测试了一种部分选择性预富集肉汤,其EIA比率更高。人工污染的熟食品的检测结果一致性为100%。
