Abstract

This study aimed to estimate the seroprevalence of bovine viral diarrhea virus (BVDV) in Moroccan cattle and to investigate associations with age, sex, breed, housing system, and geographic region. A total of 545 serum samples were randomly collected from cattle across various Moroccan regions between December 2023 and February 2024. Antibodies against BVDV were detected using a commercial competitive ELISA, and herd-level data were gathered via questionnaire. Overall, 25.0% (95% CI: 21.4 - 28.8) of samples tested seropositive. The highest prevalence was observed in the Tanger-Tetouan-Al Hoceima region (44.0%; 95% CI: 24.4 - 65.1), followed by Casablanca-Settat (32.6%; 95% CI: 26.1 - 39.6). Seropositivity was highest among cattle older than 12 months (37.5%) and in crossbred animals (86.1%) compared to purebreds (74.3%). Although not statistically significant, cattle in intensive systems showed higher prevalence (29.3%) than those in semi-intensive systems (23.2%). Females exhibited a higher seroprevalence (27.87%) than males (21.7%), with sex emerging as a significant risk factor. These findings highlight the widespread circulation of BVDV in Morocco and underscore the need for targeted control measures and improved herd management practices to mitigate virus transmission.

摩洛哥牛群病毒性腹泻流行病学研究。

本研究旨在估计牛病毒性腹泻病毒（BVDV）在摩洛哥牛的血清患病率，并调查其与年龄、性别、品种、住房系统和地理区域的关系。在2023年12月至2024年2月期间，从摩洛哥各个地区的牛中随机收集了总共545份血清样本。使用商业竞争性ELISA检测BVDV抗体，并通过问卷调查收集群体水平数据。总体而言，25.0% （95% CI: 21.4 - 28.8）的样本血清检测呈阳性。患病率最高的是丹吉尔-得土安-胡塞马地区(44.0%；95% CI: 24.4 - 65.1)，其次是Casablanca-Settat (32.6%；95% ci: 26.1 - 39.6)。12个月以上的牛血清阳性率最高（37.5%），杂交动物血清阳性率最高（86.1%），纯种牛血清阳性率最高（74.3%）。尽管没有统计学意义，但集约化系统中的牛的患病率（29.3%）高于半集约化系统（23.2%）。女性的血清患病率（27.87%）高于男性（21.7%），性别成为重要的危险因素。这些发现突出了摩洛哥BVDV的广泛传播，并强调需要采取有针对性的控制措施和改进畜群管理做法，以减轻病毒传播。

期刊介绍： The journal was created as the Croce Azzurra in 1950. A quarterly peer-reviewed journal devoted to veterinary public health and other aspects of veterinary science and medicine, Veterinaria Italiana is published by the Istituto Zooprofilattico Sperimentale dell’Abruzzo e del Molise ‘G. Caporale’ (Istituto Zooprofilattico Sperimentale dell''Abruzzo e del Molise) in Teramo, Italy. The goal of the journal is to provide an international platform for veterinary public health information from Italy and other countries, particularly those in Eastern Europe and Africa, Asia and South America. Veterinarians and veterinary public health specialists are encouraged to share their knowledge and experience on this platform.
