Abstract

Outbreaks of hepatitis-hydropericardium syndrome (HHS) caused by fowl adenovirus serotype 4 (FAdV-4) and inclusion body hepatitis (IBH) related to FAdV-8b and FAdV-11 have been increased in chickens in China since 2015. Clinical concurrent infections of FAdV-4, FAdV-8b, and FAdV-11 are quite common, yet there are no commercially available trivalent vaccines against infection by these three serotypes. In our previous study, a bivalent vaccine based on a recombinant FAdV-4, of which -1 was replaced with the of FAdV-8b, has been developed. In this study, a novel recombinant rFAdV-4-fiber/8b + 11 was constructed by inserting FAdV-11 gene into the 1966-bp deletion region of rFAdV-4-fiber/8b genome. The replication ability of the rFAdV-4-fiber/8b + 11 was similar to the parental FAdV-4. One dose immunization with the inactivated rFAdV-4-fiber/8b + 11 vaccine generated robust immune responses against FAdV-4, FAdV-8b, and FAdV-11, and provided efficient clinical protection against FAdV-4, FAdV-8b, and FAdV-11 challenge. This study provides a novel strategy for developing potential trivalent vaccines for the prevention and control of HHS and IBH.

摘要

自2015年以来,由4型禽腺病毒(FAdV-4)引起的肝炎-心包积水综合征(HHS)以及与FAdV-8b和FAdV-11相关的包涵体肝炎(IBH)在中国鸡群中的暴发有所增加。FAdV-4、FAdV-8b和FAdV-11的临床合并感染相当常见,但目前尚无针对这三种血清型感染的商业化三价疫苗。在我们之前的研究中,已开发出一种基于重组FAdV-4的二价疫苗,其中FAdV-4的-1被FAdV-8b的 所取代。在本研究中,通过将FAdV-11 基因插入rFAdV-4-fiber/8b基因组的1966-bp缺失区域,构建了一种新型重组rFAdV-4-fiber/8b + 11。rFAdV-4-fiber/8b + 11的 复制能力与亲本FAdV-4相似。用灭活的rFAdV-4-fiber/8b + 11疫苗进行一次剂量免疫可产生针对FAdV-4、FAdV-8b和FAdV-11的强大免疫反应,并为抵抗FAdV-4、FAdV-8b和FAdV-11攻击提供有效的临床保护。本研究为开发预防和控制HHS和IBH的潜在三价疫苗提供了一种新策略。
