台灣地區豬蛔蟲與豬鞭蟲感染狀況之調查
Survey of Porcine Ascariasis and Trichuriasis in Taiwan
摘要
本調查採集本省北、中、南部29場養豬場及3場屠宰場的豬隻糞便，以浮游法進行豬蛔蟲及豬鞭蟲蟲卵檢測，同時並調查屠宰場豬隻肝臟乳斑出現情形，以瞭解台灣地區豬蛔蟲與豬鞭蟲的感染現況。在1305件從養豬場收集的糞材中，豬蛔蟲卵及豬鞭蟲卵的檢出率分別為3.68%及2.84%。而在29場受檢的養豬場中，有41.38%的豬場檢出豬蛔蟲卵，31.03%的豬場檢出豬鞭蟲卵。從屠宰場收集的1356件屠宰豬隻糞材中，豬蛔蟲卵及豬鞭蟲卵的檢出率分別為29.06%及14.45%。此外，屠宰場豬隻肝臟乳斑檢查共進行4770例，其中無乳斑病變的肝臟僅佔11.99%，其餘肝臟皆有不等程度的乳斑病變。上述結果顯示，本省養豬場的豬蛔蟲及豬鞭蟲污染狀況頗為嚴重，但整體而言豬隻的感染率低，而屠宰場豬隻肝臟乳斑出現率極高。

Samples for this study were collected from twenty-nine swine herds and three slaughter houses. Fecal samples were randomly collected and examined for A. suum eggs and T. suis eggs using fecal flotation. The milk spot lesions on the liver were also inspected and categorized for pigs at slaughter. A total of 1305 collected fecal samples from herds were examined; A. suum eggs and T. suis eggs were discovered in 3.68% and 2.84%, respectively. A. suum eggs were identified in 41.38% of the examined herds, while T. suis were detected in 31.03% of herds investigated. Rectal fecal samples were collected from 1356 pigs at slaughter. A. suum and T. suis eggs were identified in 29.06% and 14.45% of the examined samples, respectively. Milk spot lesions on the liver were examined and classified from 4770 pigs at slaughter. Approximately 88% of examined livers display typical milk spot lesion, mainly grade 2, whereas only 11.99% of examined cases being were normally. The study suggested that the A. suum and T. suis occur frequently in swine herds in Taiwan, but rarely in pigs. The milk spot lesions are common in pigs at slaughter.
