- 中文摘要: 調查臺灣地區目前所飼養兔種有New Zealand、Californian、Spot、Rex和Angora等總數有1152隻。發現幼兔(離乳~二月齡)之球蟲寄生率最高達95~100%,母兔亦有所寄生,此可成為養兔場之帶原者而造成幼兔之感染而呈現症狀,甚至死亡。兔肝型球蟲(Eimeria stiedai)寄生可造成兔隻多數死亡,在其組織病理學觀察,肉眼病變上可見大小約0.1~0.5cm白色結節散布在肝臟表面及有暗綠色黏液存在腸管腔中,而在組織病理學上,在肝小葉之間的三角區內可見膽管上皮細胞增生,多數不同發育時期的球蟲寄生在上皮細胞內,膽管腔內可見球蟲卵囊,而肉芽組織病變圍繞著膽管並有許多炎症細胞浸潤,其它器官並無明顯病變。
- 英文摘要: Five breeds of rabbits, which included the New Zealand, Californian, Spot, Rex and Angora rabbit,were found from a survey of 1,152 rabbits in Taiwan. The prevalence of coccidia in young rabbits (weaning-2months old) was 95% to 100%. Adult female rabbits usually acted as carriers within the farm and trans-mitted the parasite to young rabbits, which caused severe infection with clinical signs and even death.Parasitism of hepatic coccidia (Eimeria stiedai) in the rabbit led to severe mortality. Numerous and scatteredwhite nodules about 0.1 to 0.5 cm in diameter were seen on the liver surface and dark greenish mucoid exudatewas found in intestinal lumen. Histopathologic lesions included hyperplasia of the bile duct epithelium withdifferent developmental stages of coccidia within. Oocysts could be seen in the lumen, and granulomatissues encircle the bile duct with infiltration of inflammatory cells. The other organs were not infected.
