Bovine mastitis is the most important disease affecting dairy herds worldwide, causing direct impacts on farms' profitability and food safety issues. The prevention and treatment of this pathology is especially done through antimicrobials, but the increasing antimicrobial resistance of pathogens to this disease may affect the efficiency of conventional drugs. Besides, antimicrobials residues in milk and the environment are a potential threat to human health. Thereby, the use of plant extracts and essential oils may become promising alternatives for the control of bovine mastitis. Antimicrobial properties present in several plants are well described and plant extracts and essential oils are often considered safe to animals, humans and environment. This review summarizes the current problems encountered in the conventional treatment of mastitis, the possibilities of the use of plant extracts and essential oils as alternative agents for the control of these pathogens and the limitations found in the use of these plant derivatives. Finally, the perspectives to the use of plant extracts and essential oils for the treatment of bovine mastitis are presented.

使用植物提取物和精油控制牛乳腺炎。

牛乳腺炎是影响全世界奶牛群的最重要疾病，对农场的盈利能力和食品安全问题造成直接影响。尤其是通过抗菌药物来预防和治疗这种病状，但是病原体对这种疾病的耐药性不断提高可能会影响常规药物的疗效。此外，牛奶和环境中的抗菌素残留物可能对人体健康构成威胁。因此，使用植物提取物和精油可能成为控制牛乳腺炎的有前途的替代方法。很好地描述了几种植物中存在的抗菌特性，并且通常认为植物提取物和精油对动物，人类和环境都是安全的。这篇综述总结了常规治疗乳腺炎时遇到的问题，使用植物提取物和精油作为控制这些病原体的替代剂的可能性以及使用这些植物衍生物的局限性。最后，介绍了使用植物提取物和精油治疗牛乳腺炎的观点。
