桃園北區豬隻內寄生蟲相之調查研究

Abstract

自2007年3月至2007年10月，調查桃園北區養豬場及台北縣林口鄉一山豬場共十四間 (一貫場四間，肉豬場七間，山豬場三間)，在每一飼養欄內隨機取一豬糞為材料，共取230個樣本，所有樣本皆以福馬林-乙醚離心沈澱法 (formalin-ether centrifugal sedimentation) 濃縮，並用汞碘醛 ( merthiolate-iodine-formaldehyde ) 溶液染色後鏡檢。結果顯示各種寄生蟲的總感染率為:豬蛔蟲 (Ascaris suum) 16.1% (37/230)、豬鞭蟲(Trichuris suis) 20.0% (46/230)、豬腸結節蟲 (Oesophagostomum dentatum) 18.3% (42/230)、豬球蟲 (coccidia) 68.3% (157/230)、大腸纖毛蟲 (Balantidium coli) 61.7% (142/230)、芽胞囊蟲 (Blastocystis sp.) 13.0% (30/230)、內阿米巴原蟲 (Entamoeba spp.) 77.0% (177/230)、梨形鞭毛蟲 (Giardia lamblia) 4.3% (10/230)及麥氏唇鞭毛蟲 (Chilomastix mesnili) 2.6% (6/230)。另自2007年7月至2008年5月止，分三批次從桃園北區某個屠宰場採得豬血液總共176個樣本。將血液離心得到血清後，以乳膠凝集試驗檢測豬隻血清中弓蟲 (Toxoplasma gondii) 抗體之力價，結果21.6% (38/176) 之血清呈現弓蟲抗體陽性反應。

From March to October 2007, a total of 230 swine fecal samples were randomly collected from 13 pig farms in Northern Taoyuan County and 1 pig farm in Linkou, Taipei County to investigate the endoparasitic fauna of swine. A total of 230 stool samples were examined by the formalin-ether centrifugal sedimentation technique and stained with merthiolate-iodine-formaldehyde solution for the examination of parasitic infections. Parasites found and their respective prevalence were as follows: Ascaris suum 16.1% (37/230), Trichuris suis 20.0% (46/230), Oesophagostomum dentatum 18.3% (42/230), coccidia 68.3% (157/230), Balantidium coli 61.7% (142/230), Blastocystis sp. 13.0% (30/230), Entamoeba spp. 77.0% (177/230), Giardia lamblia 4.3% (10/230) and Chilomastix mesnili 2.6% (6/230). In addition, from July 2007 to May 2008, 176 serum samples of swine were collected from a slaughterhouse in Northern Taoyuan County for the examination of antibody to Toxoplasma gondii by latex agglutination test. The seroprevalence rate was 21.6% (38/176).
