Abstract

is a genus of Gram-negative, motile, and facultative anaerobic bacteria with a worldwide distribution that contaminates multiple substrates (vegetation, food, soil, and water) and inhabits the gastrointestinal tract of birds, reptiles, and mammals, including humans. Rottnest Island is a popular tourist destination and is abundantly inhabited by quokkas (), a charismatic small wallaby. Current data on the association between and quokkas on Rottnest Island are outdated by approximately 30 years. Additionally, previous studies on quokkas on this island and mainland Western Australia did not perform physical examinations or any diagnostic tests. The aim of the project was to assess the prevalence of spp. in quokkas from Rottnest Island and mainland Western Australia and correlate the presence of the bacterium with the health of the animal. Ninety-two quokkas from Rottnest Island (n = 71) and populations on the mainland (n = 21) were screened for , and a prevalence of 47.9% and 4.8%, respectively, was determined. A total of 16 serovars were identified from 37 isolates; five of these serovars had previously not been described in the quokka. appeared to have an effect on the haematology and blood chemistry of quokkas on Rottnest Island consistent with subclinical salmonellosis. The health of Rottnest Island quokkas, and their potential impact on the health of the visitors to the island, should continue to be monitored carefully.

摘要

是革兰氏阴性、具运动性且兼性厌氧的细菌属,分布于全球,可污染多种基质(植被、食物、土壤和水),并栖息于鸟类、爬行动物和哺乳动物(包括人类)的胃肠道。罗特尼斯岛是一个受欢迎的旅游目的地,有大量短尾矮袋鼠栖息,短尾矮袋鼠是一种极具魅力的小沙袋鼠。目前关于罗特尼斯岛短尾矮袋鼠与之间关联的数据大约已有30年未更新。此外,此前对该岛及西澳大利亚大陆短尾矮袋鼠的研究未进行体格检查或任何诊断测试。该项目的目的是评估罗特尼斯岛和西澳大利亚大陆短尾矮袋鼠中 spp. 的流行情况,并将该细菌的存在与动物健康相关联。对来自罗特尼斯岛(n = 71)和大陆种群(n = 21)的92只短尾矮袋鼠进行了筛查,确定其流行率分别为47.9%和4.8%。从37株分离株中总共鉴定出16个血清型;其中5个血清型此前在短尾矮袋鼠中未被描述。似乎对罗特尼斯岛短尾矮袋鼠的血液学和血液化学有影响,这与亚临床沙门氏菌病一致。罗特尼斯岛短尾矮袋鼠的健康状况及其对该岛游客健康的潜在影响应继续受到密切监测。
