摘要
豬黴漿菌 (Mycoplasma suis)被認為是造成豬傳染性貧血 (Infectious anaemia of pigs)中相當重要的病原之一，感染之特徵有高熱、溶血性貧血、低血糖及母豬繁殖性能不佳等症狀，導致全世界養豬產業嚴重的經濟損失。本研究主要目的是了解M. suis在台灣各區域的感染現況。樣本之採集期間為2016年4月至2018年3月，並依照台灣各縣市養豬頭數之比例，隨機選取43個一貫化豬場，每場母豬與5至8週齡仔豬各10頭以上，總計共1,268個血液樣本。所有血液樣本皆以聚合酶鏈鎖反應 (polymerase chain reaction, PCR)檢測M. suis的感染情況。檢測之結果顯示，M. suis之豬場陽性率為93.02% (40/43)而豬隻陽性率為20.90% (265/1,268)，其中母豬陽性率為31.17% (197/632)以及5至8週齡仔豬陽性率為10.69% (68/636)。將所有血液樣本依其採樣地點劃分為台灣四大區域的感染情況，其M. suis陽性率由高至低分別為台灣東部35.94% (23/64)、中部24.14% (147/609)、北部16.00% (4/25)與南部15.96% (91/570)。本研究之結果顯示，M. suis普遍存在於台灣豬場且在台灣東部與中部之檢出率較高。

Mycoplasma suis is an important swine disease pathogen, and the major causes of the infectious anaemia of pigs. The clinical signs of acute infections periods include of fever, hemolytic anemia, hypoglycemia and sows reproductive failure. It also leads to the serious economic losses in pig industry all over the world. The main purpose of this study was to investigate on the infection status of M. suis in different regions of Taiwan. Blood samples were collected from 43 swine farms, in total 1,268 cases, during the April 2016 to March 2018, these samples were examined by M. suis specific polymerase chain reaction (PCR) assay. The results shows M. suis positive rate reach 20.90% (265/1,268) and 93.02% (40/43) in total samples and swine farms, respectively. 31.17% (197/632) and 10.69% (68/636) shows positive rate of M. suis for sows and nursery pigs, respectively. Based on the four regions in Taiwan, the highest M. suis positive rate was in eastern Taiwan 35.94% (23/64), the 15.96% (91/570) positive rate was the lowest in southern Taiwan, 24.14% (147/609) and 16.00% (4/25) in central and northern Taiwan, respectively. The conclusion of this study, M. suis was commonly found in swine farms of Taiwan, especially in eastern and central.
