摘要

2009年4月間在台灣的慈鯛繁殖場爆發單睪吸蟲（Haplorchis pumilio）感染症。此飼養場以市售鰻魚粉料與地下水飼養平均體重為50－60克，約7,000隻金波蘿（ Heros severus var.），每週平均飼養水溫為25－28℃。四月間大約300隻金波蘿呈現食慾不佳、爛鰭、異常色素沉著、快速呼吸及可見眾多直徑0.5－1mm白色囊腫於尾鰭表面。每隻病魚感染40－60個囊腫，經檢查與鑑定為單睪吸蟲（Haplorchis pumilio）的囊蚴感染。在微生物學檢查結果則無明顯異常。因此，建議飼養者以1 ppm benzalkonium chloride（BKC）和25 ppm formalin清除魚體表其他類寄生蟲或細菌，每週兩次持續治療一個月。同時建議先以人工清除池中所有蝸類並以10 ppm BKC於空池進行消毒，並避免野生鳥類與貓狗食用病死魚。經處置治療後，疫情獲得控制。［洪紹文、劉邦成、林荀龍、董光中、張鎮璿、詹鈞陽、王渭賢。病例報告：金波蘿之單睪吸蟲感染症。台灣獸醫誌37（4）：246－252，2011。通訊作者TEL：886-4-22840894-508，FAX：[phone]，E-mail：[e-mail]］

Outbreak of Haplorchis pumilio infestation occurred in a cichlid breeding farm in Taiwan in April, 2009. The farm held about 7,000 golden severum (Heros severus var.), weighing 50-60 g, in freshwater culture ponds. The average temperature of weekly changed culture water was 25-28℃. The fish were fed with a commercial pulverized eel diet. Approximately 300 golden severum showed signs of poor appetite, rotten fins, abnormal pigmentation and rapid respiration rate as well as numerous whitish cysts, 0.5-1 mm in diameter, on the surface of the caudal fin. There were an average number of 40-60 cysts per infected fish. A significant pathogenic parasite, metacercariae of, Haplorchis pumilio was identified. However, microbiological studies revealed no significant findings. The pond owner was advised to treat the water with 1 ppm benzalkonium chloride (BKC) and 25 ppm formalin to kill other ectoparasites and bacteria twice a week for a month. We also recommended that snails as the host of this parasite should be eradicated artificially and disinfected the cultural bonds using 10 ppm BKC before re-feeding fish. In addition, we suggested that wild birds, cats and dogs should be prevented from eating diseased or dead fish. The parasite was eventually brought under control.
