Abstract

Pigs are considered an important source of Toxoplasma gondii infection for humans. Antibodies to T. gondii were determined in serum samples from 587 pigs from Vietnam using the modified agglutination test (MAT) and found in 160 of 587 (27.2%) pigs, with MAT titers of 1:25 in 32 pigs, 1:50 in 34 pigs, 1:100 in 33 pigs, 1:200 in 24 pigs, 1:400 in 21 pigs, 1:800 in 14 pigs, and 1:3,200 in 2 pigs. Antibodies (MAT 1:20 or higher) were found in 75 of 325 (23%) finishers, 63 of 207 (32.3%) sows, and 22 of 55 (40%) boars. Results indicate high prevalence of T. gondii infection in pigs in Vietnam. This is the first report of prevalence of T. gondii in pigs from Vietnam.

摘要

猪被认为是人类弓形虫感染的重要来源。使用改良凝集试验（MAT）对来自越南的587头猪的血清样本进行了弓形虫抗体检测，结果在587头猪中的160头（27.2%）检测到抗体，其中MAT滴度为1:25的有32头猪，1:50的有34头猪，1:100的有33头猪，1:200的有24头猪，1:400的有21头猪，1:800的有14头猪，1:3200的有2头猪。在325头育肥猪中的75头（23%）、207头母猪中的63头（32.3%）和55头公猪中的22头（40%）检测到抗体（MAT 1:20或更高）。结果表明越南猪群中弓形虫感染率很高。这是越南猪群中弓形虫感染率的首次报告。
