To investigate the prevalence of pigs exposed to T. gondii in Dazhou City, Sichuan Province, 350 pigs were screened for specific antibodies to T. gondii by enzyme- linked immunosorbent assay (ELISA). The average prevalence of T. gondii antibodies were found in 10.57%(37/350)pigs, with 11.54%in intensive farm pigs and 9.15%in rural scattered pigs, differences were not statistically significant (P>0.05). 25.81%(8/31) intensive pig farms and 38.1%(8/21) natural villages raising house- hold pigs were found to be positive to T. gondii antibodies by statistical analysis of sampling sites. All the results indicated that pigs in Dazhou had a certain level of T. gondii infections and with a wide distribution, which has implications for public health in this region.%为了解达州市猪弓形虫的感染情况，本调查从8个县（市、区）31个规模场和21个散养村共随机采集猪血清样品350份，用酶联免疫吸附试验（ELISA）进行抗体水平检测。结果显示，有37份血清样品检为弓形虫抗体阳性，平均阳性率为10.57%，其中规模场、散养村散养猪阳性率分别为11.54%，9.15%，两者间差异不显著（P＞0.05）；对抽样场点弓形虫检出情况统计分析发现，25.81%（8/31）规模场和38.1%（8/21）散养村检出猪弓形虫抗体阳性。结果表明达州市规模猪场及散养猪都存在一定程度的弓形虫感染，且感染面较广，局部地区感染率较高。
