This article describes the recurrence of outbreaks of Vesicular Stomatitis in the State of Maranhão, Brazil. The procedures for treating the outbreak of vesicular disease, sample collection, laboratory tests performed, and the results obtained were described. The clinical signs and observed injuries have been described. The sera showed antibodies that cross-react between the Vesiculovirus Indiana, Cocal, and Alagoas. The serological profile shows the presence of high antibody titers for Alagoas vesiculovirus in cattle, swine, and horses. Higher antibody titers indicate the viral serotype present in the outbreak. The genetic sequencing of the isolates confirmed the presence of Alagoas vesiculovirus, which grouped with the virus isolated in 2013 from cattle from the State of Maranhão.

本文描述了巴西马拉尼昂州水疱性口炎暴发的复发情况。描述了治疗水疱病爆发、样本收集、进行的实验室测试和获得的结果的程序。已经描述了临床症状和观察到的损伤。血清显示出在印第安纳水疱病毒、 Cocal和 Alagoas之间发生交叉反应的抗体。血清学特征显示牛、猪和马中存在针对 Alagoas vesiculovirus 的高抗体滴度。较高的抗体滴度表明暴发中存在病毒血清型。分离株的基因测序证实了 Alagoas vesiculovirus 的存在，该病毒与 2013 年从马拉尼昂州的牛身上分离出的病毒归为一类。
