摘要

原藻属的绿叶单细胞微藻是牛乳腺感染的病原体,在兽医学领域受到越来越多的关注。由这些藻类引起的乳腺炎给世界各地的农民造成了重大的经济损失,并对原料奶质量和乳制品食物链安全构成了威胁。本病例报告描述了由牛原鞘菌引起的奶牛乳腺炎暴发,以及导致受影响牛群恢复和消除农场环境中原鞘菌存在的农场做法。在根除原孢子虫病中发挥关键作用的有效管理策略包括:定期筛查、及时识别、严格分离原孢子虫阳性奶牛、改变与使用草垫和去除深层床褥相关的住房制度,最后,采用过氧乙酸对茶杯进行中间消毒,以防止感染传播给其他健康个体。根除过程持续了大约三年,需要从农场移走139头牛。本案例报告中描述的纠正和预防措施为农民如何在农场成功处理原发乳腺炎提供了指导。

Eradication of Bovine Mastitis Caused by the Pathogenic Microalga Prototheca bovis on a Dairy Cattle Farm: A Case Report
The achlorophyllous unicellular microalga of the genus Prototheca, a causative agent of bovine mammary gland infection, is receiving increasing attention in the field of veterinary medicine. Mastitis caused by these algae leads to significant economic losses for farmers worldwide and represents a source of threat to raw milk quality and dairy food-chain safety. This case report describes an outbreak of bovine mastitis in dairy cattle caused by Prototheca bovis and the on-farm practices that resulted in the recovery of the affected herd and elimination of the presence of Prototheca spp. in the farm environment. Effective management strategies that played a crucial role in protothecosis eradication included regular screening, timely identification, strict separation of Prototheca-positive cows, a change of housing regime associated with the utilisation of straw mattresses and removal of deep bedding and, finally, the introduction of intermediate disinfection of teat cups with peracetic acid to prevent the spread of infection to other healthy individuals. The eradication process lasted approximately three years and required the removal of 139 cows from the farm. The corrective and preventive measures described in this case report provide guidance to farmers on how to successfully deal with protothecal mastitis on farms.

期刊介绍: Microbiology Research is an international, online-only, open access peer-reviewed journal which publishes original research, review articles, editorials, perspectives, case reports and brief reports to benefit researchers, microbiologists, physicians, veterinarians. Microbiology Research publishes ‘Clinic’ and ‘Research’ papers divided into two different skill and proficiency levels: ‘Junior’ and ‘Professional’. The aim of this four quadrant grid is to encourage younger researchers, physicians and veterinarians to submit their results even if their studies encompass just a limited set of observations or rely on basic statistical approach, yet upholding the customary sound approach of every scientific article.
