Telmatoscopus albipunctata is an insect of the Psychodidae family, with a worldwide distribution, particularly in tropical and subtropical countries. Although it does not have hematophagous habits, it has veterinary medical importance due to the mechanical transmission of protozoa and bacteria, many of which cause nosocomial infections. This dipteran has been reported as one of the causative agents of accidental myiasis in humans in several countries, and since it has not been registered in South America, the objective of the present report was to describe a rare case of accidental urinary myiasis caused by T. albipunctata (Diptera: Psychodidae) in humans in Brazil. In the present report, a 25-year-old female patient, resident of the central region of the state of Rio Grande do Sul, Brazil, sought medical attention after finding larvae in her urine. She complained of vaginal itching and skin dermatitis. The larvae were sent to the Veterinary Parasitology Laboratory of the Federal University of Santa Maria, where they were mounted on permanent slides for further taxonomic identification. Morphological characteristics allowed the identification of fourth-stage larvae and pupae of T. albipunctata. Therefore, the present work reports the first record of accidental urinary myiasis caused by T. albipunctata infection in Brazil and South America.
白纹伊蚊是双翅目蚊科昆虫,分布于世界各地,尤其在热带和亚热带国家。尽管它没有吸血的习性,但由于原生动物和细菌的机械传播,它具有兽医医学重要性,其中许多会引起医院感染。这种双翅目昆虫已被报道为在多个国家导致人类意外蝇蛆病的病原体之一,由于它尚未在南美洲登记,因此本报告的目的是描述巴西首例由白纹伊蚊(双翅目:蚊科)引起的罕见意外尿源性蝇蛆病病例。在本报告中,一名 25 岁的女性患者,居住在巴西南里奥格兰德州的中心地区,因尿液中发现幼虫而寻求医疗。她主诉阴道瘙痒和皮肤性皮炎。这些幼虫被送到圣玛丽亚联邦大学兽医寄生虫学实验室,在那里它们被安装在永久载玻片上进行进一步的分类鉴定。形态特征允许鉴定出第四期幼虫和白纹伊蚊的蛹。因此,本工作报道了巴西和南美洲首例由白纹伊蚊感染引起的意外尿源性蝇蛆病病例。
