Medicinal plants for prophylaxis and therapy of common infectious diseases in poultry have been studied for several years. The goal of this review was to systematically identify plant species and evaluate their potential in prophylaxis and therapy of common diseases in poultry caused by bacteria and gastrointestinal protozoa. The procedure followed the recommendations of the PRISMA statement and the AMSTAR measurement tool. The PICOS scheme was used to design the research questions. Two databases were consulted, and publications were manually selected, according to predefined in- and exclusion criteria. A scoring system was established to evaluate the remaining publications. Initially, 4197 identified publications were found, and 77 publications remained after manual sorting, including 38 publications with 70 experiments on bacterial infections and 39 publications with 78 experiments on gastrointestinal protozoa. In total, 83 plant species from 42 families were identified. Asteraceae and Lamiaceae were the most frequently found families with Artemisia annua being the most frequently found plant, followed by Origanum vulgare. As compared to placebo and positive or negative control groups, antimicrobial effects were found in 46 experiments, prebiotic effects in 19 experiments, and antiprotozoal effects in 47 experiments. In summary, a total of 274 positive effects predominated over 241 zero effects and 37 negative effects. Data indicate that O. vulgare, Coriandrum sativum, A. annua, and Bidens pilosa are promising plant species for prophylaxis and therapy of bacterial and protozoal diseases in poultry.

预防和治疗家禽常见传染病的药用植物——体内研究的系统评价

用于预防和治疗家禽常见传染病的药用植物已经研究了数年。本综述的目的是系统地鉴定植物物种并评估它们在预防和治疗由细菌和胃肠道原生动物引起的家禽常见疾病方面的潜力。该程序遵循 PRISMA 声明和 AMSTAR 测量工具的建议。PICOS 方案用于设计研究问题。根据预定义的纳入和排除标准，查阅了两个数据库，并手动选择了出版物。建立了一个评分系统来评估剩余的出版物。最初，找到了 4197 份已确定的出版物，经过人工排序后剩下 77 份出版物，包括 38 篇论文，其中 70 项细菌感染实验和 39 篇论文，其中 78 项胃肠道原生动物实验。总共鉴定了来自 42 个科的 83 个植物物种。菊科和唇形科是最常见的科植物，其中青蒿是最常见的植物，其次是牛至。与安慰剂组和阳性或阴性对照组相比，在 46 个实验中发现了抗菌作用，在 19 个实验中发现了益生元作用，在 47 个实验中发现了抗原生动物作用。总之，总共有 274 个积极影响超过了 241 个零影响和 37 个消极影响。数据表明，O. vulgare、Coriandrum sativum、A. annua 和 Bidens pilosa 是用于预防和治疗家禽细菌和原生动物疾病的有前景的植物物种。
