Abstract

The efficacy of the Enteric Pathogen Screen (EPS) card as a rapid method for identification of Salmonella spp. isolated in stool cultures was studied. Of the 120 lactose-negative, sucrose-negative, H2S-producing colonies tested, 74 were identified as Salmonella enteritidis by conventional methods. The reading of the EPS card after 2 h of incubation yielded a sensitivity of 47.2% and a specificity and positive predictive value of 100%, with a negative predictive value of 54.1%. In the final reading of 4 h, a sensitivity of 97.2% and a specificity of 86.9% were obtained, with a positive predictive value of 92.3% and a negative predictive value of 95.2%.

摘要

研究了肠道病原体筛查（EPS）卡作为快速鉴定粪便培养物中分离出的沙门氏菌属的方法的有效性。在测试的120个乳糖阴性、蔗糖阴性、产H2S菌落中，通过传统方法鉴定出74个为肠炎沙门氏菌。孵育2小时后读取EPS卡，灵敏度为47.2%，特异性和阳性预测值为100%，阴性预测值为54.1%。在4小时的最终读取中，灵敏度为97.2%，特异性为86.9%，阳性预测值为92.3%，阴性预测值为95.2%。
