腹泻4项病毒抗原检测在疑似食物中毒中的临床应用

目的探讨腹泻4项病毒抗原(轮状病毒、肠道腺病毒、诺如病毒、星状病毒)联合检测在疑似食物中毒中的应用价值。方法收集疑似食物中毒患者急性期粪便176份,采用荧光免疫层析法进行腹泻4项病毒抗原检测,同时进行致病菌培养鉴定。结果 176份疑似食物中毒患者粪便标本中,检出1株志贺菌,未检出其他致病菌;腹泻4项病毒抗原中轮状病毒、肠道腺病毒、诺如病毒、星状病毒抗原的检出率分别为9.66%、1.70%、14.77%、2.84%。结论应用腹泻4项病毒抗原联合检测可明确病毒病原体,及时识别和预警食源性疾病暴发。

Clinical application of 4-item diarrhea viral antigen in suspected food poisoning

Objective To investigate the application value of combined detection of four diarrhea viral antigens (rotavirus ,enteric adenovirus ,norovirus ,astrovirus) in suspected food poisoning .Methods One hundred and seventy-six stool samples from the pa-tients with acute phase of suspected food poisoning were collected and performed the 4-item viral antigen detection by adopting the immunofluorescence chromatography ,and at the same time the culture and identification of pathogenic bacteria at the same time were performed .Results Among 176 stool samples of patients with suspected food poisoning ,one strain of Shigella was detected and other pathogens were not detected out ;the detection rates of four viral antigens of rotavirus ,enteric adenovirus ,norovirus and astrovirus were 9 .66% ,1 .70% ,14 .77% and 2 .84% respectively .Conclusion The combined detection of four diarrhea viral anti-gens can definite viral pathogens ,timely identify and early warn food-borne disease outbreaks .
