Twenty five children between 4-12 years of age hospitalized with a clinical diagnosis of enteric fever were studied for evaluating the practicality and sensitivity of duodenal string-capsule culture (DSCC) and compared with conventional cultures from blood (BC), urine (UC) and stool (SC). Duodenal string capsule (DSCC) was successfully inserted in 18 patients (72%). Insertion of DSCC failed in 7 patients (28%) and all of them were below 6 years of age. Salmonella typhi was isolated from DSCC and/or BC in 13 cases (72.2%). DSCC was positive in 11 out of 13 confirmed cases of typhoid fever (84.6%). BC was positive in 8 cases (61.5%). DSCC was successful in isolating the organism in about 30% more cases than BC. Duodenal string test was a simple, non-invasive and a reliable test which when used in combination with BC could identify almost all cases of enteric fever irrespective of duration of fever and prior use of antibiotics.
对25名4至12岁因临床诊断为伤寒热而住院的儿童进行了研究，以评估十二指肠线囊培养（DSCC）的实用性和敏感性，并与血液（BC）、尿液（UC）和粪便（SC）的传统培养结果进行比较。18例患者（72%）成功插入十二指肠线囊（DSCC）。7例患者（28%）插入DSCC失败，且所有失败患者均低于6岁。13例（72.2%）患者的DSCC和/或BC中分离出伤寒杆菌。13例确诊伤寒热病例中有11例（84.6%）DSCC呈阳性。8例（61.5%）BC呈阳性。DSCC成功分离出病原体的病例比BC多约30%。十二指肠线囊试验是一种简单、无创且可靠的试验，与BC联合使用时，无论发热持续时间和先前是否使用过抗生素，几乎可以识别所有伤寒热病例。
