中文摘要 | 1925年日人杉木氏發現台灣家豬感染腎圓蟲,惟70餘年來迄無報告文獻。本實驗 室在進行條蟲之研究, 由台東牧場購進 35 隻小耳豬 (Small Ear Miniature, SEM pig)( 平均體重 29.5 公斤 )。 感染囊狀幼蟲 59-74 天後,分別用電擊法殺死,去皮後,取出內 臟器官,用肉眼檢查,發現 4 隻豬 (11 % ) 傳染腎圓蟲。 檢獲蟲體 65 隻,分佈似橫隔 膜 (44.6 % ) 最多,次為腎 (30.8 % ),肝 (12.3 % ),腹肌 (4.6 % ),肺 (3.1 % ),胸肌,腰肌及脊肌 (0.2 % ) 均最低。雌蟲 (34X1.4mm) 大於椎蟲 (31X1.2mm.。 雌蟲 在橫隔膜 (39X1.6mm) 二腎臟 (36X1.5mm) >肝臟 (30X1.2mm)。雄蟲在橫隔膜 (31X1.2mm) 與灸腕者 (30X1.2mm) 相似。新鮮蟲體淡粉色,體表具有橫紋,兩側各有一條明顯側腺。口 越呈杯狀。雌蟲口囊 (295X112 μ m) 大於堆蟲 (268X99 μ m.,食道分為兩部分,後者膨 大,雌蟲者 (1,023X334 μ m) 大於雄蟲 (810X307 μ m)。 雄蟲交尾衰短小,分葉不明顯 。交尾刺兩根平行,具有橫紋翼膜,近端有睪丸引帶,不等長。雌蟲尾端呈圓錐形,在肛門 兩側各有一個球狀尾泡。 蟲卵呈長目形, 殼薄, 無色透明, 平均 (105X68 μ m) 含有 20-30 分裂細胞,隨尿排出體外。 |
英文摘要 | Of the 35 pigs (average weight 29.5 kg) bought from the Taitung Pig Farm for studies on taeniasis, four pigs (11%) were found to be infected with S. dentatus by gross examination of the viscera. A total of 65 worms was collected. The distribution of the worms was highestin the diaphragm (44.6%), followed by the kidneys (30.8%), liver (12.3%), abdominal muscles(4.6%), and lungs (3.1%). Sternothyroid muscle, quadratus lumbrorum muscle, and spinalis thoralis muscle had the lower distribution of 2.0%. Female worms (34 X 1.4 mm) were larger than themale ones (31 X 1.2 mm). The fresh worms were light pink in color and have straits on the body surface. There was a lateral line on each of two sides. Male bursa was small, short, and with insignificant lobes. The two spicules with spicule sheath and gubernaculum were unequal and parallel. The caudal part of the female worm was conical and with a caudal bubble. Eggs (105 X 68 pm) were ovoid, thin-shelled, transparent, and in the 20-30-cell stage. The eggs were passed with the urine. |
