In Australia, amoebiasis is thought to occur in travellers, immigrants from endemic areas, and among men who have sex with men. Prevalence of amoebiasis in communities with immigrants from -endemic countries is unknown. The present study is a retrospective case series analysis of patients with laboratory-confirmed amoebiasis from Western Sydney Local Health District, Australia, between years 2005 and 2016. Forty-nine patients with amoebiasis were identified, resulting in an estimated annual incidence of up to 1.1 cases per 100,000 adults. Many were born in Australia (15/47) and India (12/47). Three patients (3/37) had no history of overseas travel, two others had not travelled to an endemic country, and an additional two had a very remote history of overseas travel; one died of fulminant amoebic colitis. Three patients (3/16) were employed in the food industry and one had a history of colonic irrigation in an Australian 'wellness clinic'. Patients had invasive amoebiasis with either liver abscess (41/48) or colitis (7/48), diagnosed most commonly by serology. Invasive procedures were common, including aspiration of liver abscess (28/41), colonoscopy (11/49), and partial hepatectomy (1/49). Although rare, local acquisition of amoebiasis occurs in Western Sydney and contributes to significant morbidity and hospital admissions.
在澳大利亚，阿米巴病被认为发生在旅行者、来自流行地区的移民以及男男性行为者中。来自流行国家的移民社区中阿米巴病的患病率尚不清楚。本研究是对2005年至2016年间澳大利亚西悉尼地方卫生区实验室确诊的阿米巴病患者进行的回顾性病例系列分析。共确定了49例阿米巴病患者，估计每年发病率高达每10万成年人1.1例。许多患者出生在澳大利亚（15/47）和印度（12/47）。3例患者（3/37）无海外旅行史，另外2例未前往流行国家，还有2例有非常久远的海外旅行史；1例死于暴发性阿米巴结肠炎。3例患者（3/16）从事食品行业，1例有在澳大利亚一家“健康诊所”进行结肠灌洗的病史。患者患有侵袭性阿米巴病，表现为肝脓肿（41/48）或结肠炎（7/48），最常见的诊断方法是血清学检查。侵入性操作很常见，包括肝脓肿穿刺抽吸（28/41）、结肠镜检查（11/49）和部分肝切除术（1/49）。虽然罕见，但西悉尼地区存在本地感染的阿米巴病病例，这会导致显著的发病率和住院率。
