白星花金龟（Telmatoscopus albipunctatus）是一种世界性分布的蝇类，广泛分布于潮湿环境中。它是医学上最重要的昆虫之一（尤其在城市环境中），可能会引发蝇蛆病。已报道有尿路蝇蛆病以及包括肠道、鼻腔、肺部和皮肤等其他部位的感染。这是中国广州一名中年女性感染白星花金龟的首例病例报告。在本报告中，一名50岁女性因早晨排尿时发现幼虫而来到中国广州南方医科大学第三附属医院；在过去两个月内，这种情况每两天发生一次。她主诉尿频和尿急。尿液检测表明，除了轻微的尿路感染外，所有指标均正常。随后，幼虫被送往中国广州中山大学中山医学院寄生虫学系寄生虫感染诊断科。使用体视显微镜和透射电子显微镜进行形态学观察。在此基础上，通过聚合酶链反应（PCR）特异性扩增细胞色素氧化酶亚基1（COX1）基因。利用PCR产物的序列分析和系统发育分析来鉴定物种。形态学分析结合分子生物学方法表明，该昆虫是白星花金龟的四龄幼虫。我们的研究结果显示，这是一例50岁女性尿路感染白星花金龟幼虫的病例，研究结果提示临床医生应警惕这种感染。
Telmatoscopus albipunctatus, a cosmopolitan fly, is widely distributed throughout moist environments. It is one of the most medically important insects (especially in urban environments) that may potentially cause myiasis. Urinary myiasis and other sites of infestation, including the intestine, nasal passages, lung, and derma, have been reported. This is the first case report of a Chinese middlescent woman infected with T. albipunctatus in Guangzhou, China. In the present report, a 50-year-old woman came to The Third Affiliated Hospital of Southern Medical University, Guangzhou, China, because larvae were found when urinating in the morning; this had occurred every two days within the past two months. She complained of frequent micturition and urgency. Urine tests indicated that all indexes were normal except for slight urinary tract infection. Subsequently, the larvae were sent to the diagnostic section for parasitic infection in the Department of Parasitology, Zhongshan School of Medicine, Sun Yat-sen University, Guangzhou, China. The stereoscopic microscope and transmission electron microscope were used for morphological observation. On this basis, the cytochrome oxidase subunit 1 (COX1) gene was specifically amplified by PCR. Sequence analysis of the PCR product and phylogenetic analysis were used to identify the species. Morphological analysis combined with molecular biology methods indicated that the insect was the fourth instar larvae of T. albipunctatus. Our results show that this was a case of a 50-year-old woman infected with T. albipunctatus larvae in her urinary tract, and the findings suggest that clinicians should be vigilant for this infection.
