The aim of this work was to detect serum antibodies specific to influenza viruses in swine in Brazil. Serum samples of 355 pigs from 17 herds in Minas Gerais state were tested by hemagglutination inhibition (HI) for antibodies against H1N1 swine (SIV) and human influenza viruses, and H3N2 SIV. HI revealed that 158 animals (44·5%) and 11 herds (64·7%) were positive for H1N1 SIV, 36 animals (10·1%) and four herds (23·5%) were positive for H3N2 SIV, and 136 animals (38·3%) and 10 herds (58·8%) were positive for H1N1 human. This study indicates that swine influenza is disseminated throughout Minas Gerais state, Brazil.
本研究旨在检测巴西猪群中针对流感病毒的血清抗体。对来自米纳斯吉拉斯州 17 个畜群的 355 份猪血清样本进行血凝抑制（HI）试验，以检测针对 H1N1 猪流感病毒（SIV）和人源流感病毒以及 H3N2 SIV 的抗体。HI 结果显示，158 头动物（44.5%）和 11 个畜群（64.7%）对 H1N1 SIV 呈阳性，36 头动物（10.1%）和 4 个畜群（23.5%）对 H3N2 SIV 呈阳性，136 头动物（38.3%）和 10 个畜群（58.8%）对 H1N1 人源病毒呈阳性。本研究表明，流感在巴西米纳斯吉拉斯州广泛传播。
