The avian blood fluke, Austrobilharzia terrigalensis (Trematoda: Schistosomatidae), is recorded in Western Australia for the first time, and is implicated as the cause of dermatitis among users of the Swan estuary in Perth. Quantitative data provided by a questionnaire sent to affected people showed that infection occurred from November to March in the shallows throughout the "middle" estuary and that children from five to 14 years old were most frequently affected. Most cases of dermatitis were contracted between 11 a.m. and 12 noon--the time of day when the emergence of A. terrigalensis cercariae from the intermediate host, Velacumantus australis, reaches a peak. Exposure times varied considerably, but were generally between 30 and 90 minutes, with dermatitis appearing 12 to 24 hours later. The lesions, which were sometimes widespread over the body and itched severely, persisted for one to two weeks and longer if they were secondarily infected. Approximately 38% of affected people consulted doctors about their condition. These results are discussed in relation to findings on the ecology of the parasite's intermediate and definitive hosts.
禽血吸虫澳洲特瑞曼吸虫（吸虫纲：裂体吸虫科）首次在西澳大利亚被记录，被认为是珀斯天鹅河口使用者患皮炎的病因。一份发给受影响人群的调查问卷所提供的定量数据显示，感染发生在11月至次年3月，整个“中部”河口的浅水区都有感染情况，5至14岁的儿童受影响最为频繁。大多数皮炎病例是在上午11点至中午12点之间感染的——这是澳洲特瑞曼吸虫尾蚴从中间宿主南方威拉库曼螺中逸出达到高峰的时段。暴露时间差异很大，但一般在30至90分钟之间，皮炎在12至24小时后出现。这些病变有时遍布全身，奇痒无比，会持续一到两周，如果继发感染则持续更长时间。约38%的受影响人群就自身病情咨询了医生。结合该寄生虫中间宿主和终宿主的生态学研究结果对这些结果进行了讨论。
