在中国的人和家禽中都发现了高致病性和低致病性的H7N9甲型流感病毒感染,大多数人感染病例与接触受感染的家禽有关。因此,有必要建立一种快速、简便的检测禽类中H7N9禽流感病毒的方法。本研究制备了13株抗H7N9 IAV血凝素的单抗,并根据这些变异株和野生型单抗的反应性确定了三个关键的氨基酸表位(198、227、235)。我们利用识别抗原表位227和235的两株单抗建立了H7N9禽流感病毒的免疫层析检测方法。该方法具有良好的特异性、稳定性和灵敏度,对拭子和组织样品的检出限为2.5log10EID50/0.1mL,适用于临床样品的分析。该方法为家禽中H7N9禽流感病毒的快速检测提供了一种有效的方法。
Both high- and low-pathogenic H7N9 influenza A virus (IAV) infections have been found in human and poultry in China, and most human cases are related to contact with infected poultry. It is necessary to develop a rapid and simple method to detect H7N9 IAV in poultry. In this study, 13 monoclonal antibodies (McAbs) against the H7N9 IAV hemagglutinin were developed, and three critical amino acid epitopes (198, 227, 235) were identified based on the reactivity of these variant and wild-type strains with the McAbs. We developed an immunochromatographic assay for H7N9 AIVs using two McAbs recognizing the epitope position 227 and 235. The assay had good specificity, stability, and sensitivity, with a detection limit of swab and tissue samples of 2.5 log10EID50/0.1 mL, which is suitable for the analysis of clinical samples. This assay provides an effective method for the rapid detection of H7N9 AIVs in poultry.
