The aim of this study was to describe an outbreak of gastroenteritis due to rotavirus in a geriatric nursing home.
Stool samples from 8 patients were studied. Antigen detection was carried out by ELISA, and molecular typing was performed by RT-PCR.
Rotavirus antigen was detected in 6 patients. Typing demonstrated a common genotype (G9P[8]).
The outbreak detected in elderly persons suggests a loss of immunity with age or a lack of protection against an emergent genotype.
本研究旨在描述一家老年疗养院中由轮状病毒引起的胃肠炎暴发情况。
对8例患者的粪便样本进行了研究。通过酶联免疫吸附测定法进行抗原检测，并通过逆转录聚合酶链反应进行分子分型。
在6例患者中检测到轮状病毒抗原。分型显示为一种常见基因型（G9P[8]）。
在老年人中检测到的此次暴发提示随着年龄增长免疫力丧失或缺乏针对新出现基因型的保护。
