【摘要】：为调查武汉市美洲大蠊感染蠊缨滴虫(Lophomomas blattarum)的情况,解剖镜下分离110只美洲大蠊成虫肠道,用0.6%氯化钠溶液洗涤剪开的肠道,收集洗涤液,涂片并作吉氏染色,显微镜(×1000)下鉴定。结果显示,共44份肠道洗涤液涂片中发现蠊缨滴虫疑似物。虫体呈卵圆形或梨形,体长20~40μm,一端有成簇的多根鞭毛。经固定、染色后,可见虫体胞浆呈蓝色;细胞核1个,呈紫褐色,靠近虫体前端;轴柱在虫体前端呈萼状(轴罩),胞核位于其中,轴柱向后延伸至虫体末端,经鉴定确认为副基体门动鞭毛纲超鞭毛目中的蠊缨滴虫。提示武汉市美洲大蠊的蠊缨滴虫感染率为40.0%(44/110)。
[Abstract]:In order to investigate the infection of Periplaneta Americana with (Lophomomas blattarum), the intestinal tract of 110 adult Blattella Americana was dissected under anatomic microscope. The intestinal tract was scrubbed and cut with 0.6% sodium chloride solution. Identified by microscope (脳 1000). The results showed that a total of 44 samples of intestinal washing fluid smears were found suspected of Trichomonas cockroaches. The insect body is oval or pear-shaped, with a length of 20 ~ 40 渭 m and clusters of flagellum at one end. After fixation and staining, the cytoplasm of the worm was blue, and the nucleus was purplish brown and close to the front of the body. The axonal column is calyx (axon) on the front end of the parasite, and the nucleus is located in it. The axial column extends backward to the end of the parasite, and it is identified as Trichomonas cockroaches in the superflagellates of the order Paramentum. The results suggest that the infection rate of Trichomonas Americana is 40.0% (44 / 110).
