This report describes a case of disseminated proliferative mesocestoidosis in a French bulldog from Aichi, Japan. In July 2023, the dog presented with chronic enteritis, and histological examination of the endoscopic biopsy specimen revealed parasites with suckers. Three months later, numerous tetrathyridia were detected in the inguinal mass. In April 2024, polymorphic tetrathyridia were detected on the visceral organs. These parasites were identified as Mesocestoides vogae (Cyclophylidea: Mesocestoididae) based on morphological features and sequence analyses. In Japan, M. vogae has only been reported in domestic dogs, with five cases of intestinal infection and one case of abdominal infection. This report is the first case of both intestinal and extraintestinal infections in the westernmost region of Japan.
本报告描述了一例来自日本爱知县的法国斗牛犬播散性增殖性中绦虫病病例。2023年7月,该犬出现慢性肠炎,内镜活检标本的组织学检查发现带有吸盘的寄生虫。三个月后,在腹股沟肿块中检测到大量四盘蚴。2024年4月,在内脏器官上检测到多形性四盘蚴。根据形态学特征和序列分析,这些寄生虫被鉴定为沃氏中绦虫(圆叶目:中绦虫科)。在日本,沃氏中绦虫仅在犬中被报道过,有5例肠道感染和1例腹部感染。本报告是日本最西部地区首例肠道和肠外感染病例。
