The state of Queensland has the highest incidence of Q fever in Australia. In recent years, there has been an increase in human cases where no contacts with the typical reservoir animals or occupations were reported. The aim of this study was to determine the seroprevalence of Coxiella burnetii in Australian native animals and introduced animals in northern and southeastern Queensland. Australian native marsupials sampled included the brushtail possum (Trichosurus vulpecula) and common northern bandicoot (Isoodon macrourus). Introduced species sampled included dingoes (Canis lupus dingo), cats (Felis catus), foxes (Vulpes vulpes) and pigs (Sus scrofa). Serum samples were tested by ELISA for both phase II and phase I antigens of the organism using an Australian isolate. The serological evidence of C. burnetii infection demonstrated in these species has public health implications due to their increasing movement into residential areas in regional Queensland. This study is the first known investigation of C. burnetii seroprevalence in these species in northern Queensland.
昆士兰州是澳大利亚 Q 热发病率最高的州。近年来，报告了越来越多的人类病例，但没有接触过典型的储存宿主动物或职业。本研究的目的是确定昆士兰州北部和东南部澳大利亚本土动物和引入动物中贝氏柯克斯体的血清流行率。采样的澳大利亚有袋类动物包括帚尾袋貂（Trichosurus vulpecula）和普通袋狸（Isoodon macrourus）。采样的引入物种包括野狗（Canis lupus dingo）、猫（Felis catus）、狐狸（Vulpes vulpes）和猪（Sus scrofa）。使用澳大利亚分离株，通过 ELISA 检测血清样本中该生物的 II 期和 I 期抗原。由于这些物种越来越多地进入昆士兰州地区的居民区，因此其感染贝氏柯克斯体的血清学证据具有公共卫生意义。本研究是首次在北昆士兰州对这些物种进行贝氏柯克斯体血清流行率调查。
