Abstract

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.

巴西伯南布哥州半干旱区山羊群中施马伦贝格病毒调查及刚地弓形虫血清学状况的最新进展

生殖障碍是动物生产的一个重大障碍。在这方面，施马伦贝格病毒（Schmallenberg virus， SBV）和刚地弓形虫（Toxoplasma gondii）感染与小型反刍动物的繁殖失败有关，从而导致经济损失。本研究旨在对巴西东北部伯南布哥州Agreste地区山羊养殖场的施马伦贝格病毒和刚地弓形虫感染进行血清流行病学调查。368只动物抗sbv抗体均未阳性，15.48%（57/368）动物抗t抗体阳性。刚地IgG抗体。此外，还观察到弓形虫感染与集约化养殖方式、乳制品生产和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里斯特地区的山羊种群中传播。然而，弓形虫感染持续存在，并可能与生殖损失有关，从而对该地区的山羊生产者构成潜在的经济风险。

期刊介绍： Veterinary Parasitology: Regional Studies and Reports focuses on aspects of veterinary parasitology that are of regional concern, which is especially important in this era of climate change and the rapid and often unconstrained travel of people and animals. Relative to regions, this journal will accept papers of the highest quality dealing with all aspects of disease prevention, pathology, treatment, epidemiology, and control of parasites within the field of veterinary medicine. Also, case reports will be considered as they add to information related to local disease and its control; such papers must be concise and represent appropriate medical intervention. Papers on veterinary parasitology from wildlife species are acceptable, but only if they relate to the practice of veterinary medicine. Studies on vector-borne bacterial and viral agents are suitable, but only if the paper deals with vector transmission of these organisms to domesticated animals. Studies dealing with parasite control by means of natural products, both in vivo and in vitro, are more suited for one of the many journals that now specialize in papers of this type. However, due to the regional nature of much of this research, submissions may be considered based upon a case being made by the author(s) to the Editor. Circumstances relating to animal experimentation must meet the International Guiding Principles for Biomedical Research Involving Animals as issued by the Council for International Organizations of Medical Sciences (obtainable from: Executive Secretary C.I.O.M.S., c/o W.H.O., Via Appia, CH-1211 Geneva 27, Switzerland).
