摘要
沙囊虫属可引起鸽子原虫性脑炎，这是一种神经元疾病。一羽雌鸽出现肢体扭转症，大脑半球有一坏死区，周围有血管周围充血、神经胶质增生、肉芽肿灶和脑膜炎等病变。脑干也有非坏死性病变。在病变部位的神经髓鞘和神经元内观察到完整和变性的裂殖体。从石蜡包埋的脑组织中提取脱氧核糖核酸（DNA），经凝胶电泳后进行基因分析，使用 28S 核糖体核糖核酸和内部转录间隔区-1 的特异引物组确定沙雷氏菌属。DNA 测序证实与 S. calchasi 有明显的同源性。这是日本首次报道由卡氏沙雷氏菌引起的岩鸽恶性脑膜脑炎。
Meningoencephalitis with malacia caused by Sarcocystis calchasi in a rock pigeon in Japan.
Sarcocystis spp. cause pigeon protozoan encephalitis, a neuronal disease. A female pigeon exhibiting torticollis had a necrotic area in the cerebral hemisphere surrounded by lesions with perivascular cuffing, gliosis, granulomatous foci, and meningitis. Non-necrotic lesions were also observed in the brainstem. Intact and degenerative schizonts were observed within the neuropils and neurons in the lesions. Deoxyribonucleic acid (DNA) was extracted from paraffin-embedded brain tissues and genetically analyzed after gel electrophoresis to determine Sarcocystis spp. using specific primer sets for 28S ribosomal ribonucleic acid and internal transcribed spacer region-1. DNA sequencing confirmed a significant homology with S. calchasi. This is the first report of meningoencephalitis with malacia caused by S. calchasi in a rock pigeon in Japan.
期刊介绍：
JVMS is a peer-reviewed journal and publishes a variety of papers on veterinary science from basic research to applied science and clinical research. JVMS is published monthly and consists of twelve issues per year. Papers are from the areas of anatomy, physiology, pharmacology, toxicology, pathology, immunology, microbiology, virology, parasitology, internal medicine, surgery, clinical pathology, theriogenology, avian disease, public health, ethology, and laboratory animal science. Although JVMS has played a role in publishing the scientific achievements of Japanese researchers and clinicians for many years, it now also accepts papers submitted from all over the world.
