民國六十六年度調查臺灣中部地區四縣(臺中、南投、彰化、雲林)之28鄉鎮地區養豬戶,共採取350欄及日月潭地區40欄豬糞,經檢查結果發現有多種寄生蟲在人畜公共衛生上有關。中部地區四縣之豬欄單位寄生蟲感染率與公共衛生有關之寄生蟲調查,以大腸纖毛蟲(Balantidiumcoli) 60.6% (212/350)為最高,其次是豬鞭蟲(Trichuris suis) 36.9% (129/350),豬蛔蟲(Ascaris suum) 22.9% (80/350)和縮小包膜絛蟲(Hymenolepis diminuta) 1.7%(6/350)。而日月潭地區亦以大腸纖毛蟲 65%(26/40)為最高,其次豬蛔蟲42.5%(17/40),豬鞭蟲30%(12/40),中華肝吸蟲(Clonorchis sinensis) 17.5%(7/40),橫川異形吸蟲(Metagonimus yoko-gawai) 15% (6/40)和縮小包膜絛蟲 2.5% (1/40)。在形態觀察之研究方面收集日本境內所發生的牛蛔蟲症病例,以光學顯微鏡及掃描電子顯微鏡檢查,發現豬蛔蟲可以在小牛寄生引起牛蛔蟲症。又以豬蛔蟲卵感染仔牛及兔的實驗證明,豬蛔蟲可以在異宿主內發育,因此以內臟幼蟲移行症(Visceral larva migrans)的概念,解釋家畜和人的臟器組織內所見到的幼線蟲時,在臺灣豬蛔蟲寄生很普遍的現況下,由環境因子的變化,在公共衛生上,流行病學上,今後對於豬蛔蟲在人與家畜之寄生有其注重的必要,尤其在臺灣農村小規模綜合經營方式下,更必須注意此種寄生蟲病的污染與發生。
- 英文摘要:
According to the survey of parasitic infec-tion of swine in central part of Taiwan (28 ruraldistricts in Taichung, Changhua, Nantou andYunlin counties and one in Sun-Moon lake area)in 1977, there were many parasites related tothe public health. The results showed that thepercentage of pig pens infected were Balantidiumcoli 60.6% (212/350), Trichuris suis 36.9% (129/350), Ascaris suum 22.9% (80/350), Hymenolepisdiminuta 1.7% (6/350) in those counties andBalantidium coli 65% (26/40), Ascaris suum 42.5%(17/40), Trichuris suis 30% (12/40), Clonorchissinensis 17.5% (7/40), Metagonimus yokogawai15% (6/40) and Hymenolepis diminuta 2.5%(1/40) in Sun-Moon lake area respectively. Based on the finding of the ascariasis caseof calves which occurred in Japan, Ascaris suumcould be parasitic to calf to cause the bovineascariasis from their epizootiological and mor-phological observation by means of light micro-scopy and scanning electromicroscopy. Alsofrom the experimental results showed that theegg of pig ascaris (Ascaris suum) could infectcalf and rabbit. Those results demonstrated thatAscaris suum could live in many other hosts. Here in Taiwan had a high rate of swineinfected by Ascaris suum which also could befound their larvae in livestock and human viscer-al tissues. It is worthy to pay much attentionin preventing this parasitic disease, especiallythe small scale of integrated management incountryside.
