目的调查研究广西是否存在猪人肉孢子虫的感染情况,并建立感染模型,研究广西猪人肉孢子虫的易感性及临床药物治疗效果。方法选择有吃生猪肉习惯的地区为调查点,对1岁以上常住户口居民取新鲜粪便用硫酸锌漂浮法离心镜检肉孢子虫孢子囊。用薛氏糖漂浮法从肉孢子虫自然感染患者粪便中收集孢子囊,用吞食法感染实验猪,感染后第56d将其杀死取新鲜肌肉100g和50g,用同法分别感染实验猴和志愿者。实验猪和调查乡(镇)市售猪肉抽样取肌肉标本每部位各2g,用压片法镜检肉孢子虫包囊。结果调查7个县11个乡(镇)30个村庄3428人,其中6个县6个乡(镇)12个村庄人群肉孢子虫平均自然感染率2.07%。10个乡(镇)市售猪肉肉孢子虫平均感染率33.64%。实验猪感染后第56d查见肉孢子虫包囊,志愿者感染后第12d粪检查见孢子化的孢子囊或卵囊。结论广西流行猪人肉孢子虫病。
Objective To investigate whether Guangxi S.cosia infection exists and to establish an infection model to study the susceptibility of Guangxi Sarcocystis spp. To clinical drug treatment. Methods Select the habit of eating raw pork area as a survey point for residents over the age of 1 permanent residents to take fresh faecal scintillation using Zinc Sulfate centrifuge microscopy sporocysts. Sporangium was collected from the feces of patients with natural infection of Sarcocystis spp by means of Schaeffer’s float method. The swine was inoculated with swine inoculation method. After 56 days of infection, the spleens were infected with 100g and 50g fresh muscle, respectively. By. Experimental pigs and survey township (town) pork samples taken from the muscle samples of each part of each 2g, with the screening method of microscopic sarcocyst cysts. Results The survey investigated 3428 people in 11 villages (towns) of 30 villages in 7 counties, of which the average natural infection rate of schistosomiasis was 2.07% in 12 villages in 6 townships of 6 counties. The average infection rate of Sarcocycas in 10 townships (towns) was 33.64%. Sargassum cysts were detected on the 56th day after infection in experimental pigs, and sporocysts or oocysts were observed on the 12th day after volunteer infection. Conclusion Guangxi swine sarcocystosis.
