摘要

目的在美国和世界范围内，恶性肉杆菌被认为是一种新兴的沙门氏菌病原体。方法从美国弗吉尼亚州商业养殖设施的死亡虹鳟鱼后肾和皮肤中培养出C. maltaromatium，并通过额外的表型和分子表征证实了这一结果。结果根据临床表现、尸检观察、组织病理学和细菌培养，推定诊断为镰状芽孢杆菌所致细菌性败血症。结论首次在美国维吉尼亚州虹鳟鱼中发现maltaromatium。

First isolation of Carnobacterium maltaromaticum from farmed Rainbow Trout in Virginia

Objective

Carnobacterium maltaromaticum is considered an emerging pathogen of salmonids in the United States and around the world.

Methods

Bacterial cultures obtained from the posterior kidney and skin of moribund Rainbow Trout Oncorhynchus mykiss from a commercial aquaculture facility in Virginia, USA, grew C. maltaromaticum, which was confirmed by additional phenotypic and molecular characterization.

Result

A presumptive diagnosis based on the clinical signs, necropsy observations, histopathology, and bacterial cultures was bacterial septicemia due to C. maltaromaticum.

Conclusion

This represents the first documentation of C. maltaromaticum in Rainbow Trout from Virginia.

期刊介绍： The Journal of Aquatic Animal Health serves the international community of scientists and culturists concerned with the health of aquatic organisms. It carries research papers on the causes, effects, treatments, and prevention of diseases of marine and freshwater organisms, particularly fish and shellfish. In addition, it contains papers that describe biochemical and physiological investigations into fish health that relate to assessing the impacts of both environmental and pathogenic features.
