Reproductive disorders represent a significant obstacle to animal production. In this regard, infections with Schmallenberg virus (SBV) and Toxoplasma gondii have been linked to reproductive failures in small ruminants, leading to economic losses. This study aimed to conduct a seroepidemiological investigation of Schmallenberg virus and Toxoplasma gondii infection in goat farms located in the Agreste region of Pernambuco, northeastern Brazil. A total of 368 animals were analyzed, none of which were positive for anti-SBV antibodies, and 15.48 % (57/368) tested positive for anti-T. gondii IgG antibodies. Furthermore, a significant association was observed between T. gondii infection and intensive farming practices, dairy production, and the water source provided to the animals. Thus, SBV is not yet circulating in the goat population of the Agreste region of Pernambuco State. However, T. gondii infections persist and may be associated with reproductive losses, thereby posing potential economic risks to goat producers in the region.
生殖障碍是动物生产的一个重大障碍。在这方面，感染施马伦贝格病毒（SBV）和弓形虫与小反刍动物的繁殖失败有关，会导致经济损失。本研究旨在对位于巴西东北部伯南布哥州阿格雷斯特地区的山羊养殖场进行施马伦贝格病毒和弓形虫感染的血清流行病学调查。共分析了368只动物，其中没有一只抗SBV抗体呈阳性，15.48%（57/368）的抗弓形虫IgG抗体检测呈阳性。此外，观察到弓形虫感染与集约化养殖方式、乳制品生产以及提供给动物的水源之间存在显著关联。因此，SBV尚未在伯南布哥州阿格雷斯特地区的山羊群体中传播。然而，弓形虫感染持续存在，可能与繁殖损失有关，从而给该地区的山羊养殖户带来潜在的经济风险。
