Erysipelothrix rhusiopathiae septicemia was diagnosed in three of four moose found dead in Algonquin Provincial Park, Ontario, Canada, in the spring of 1989. Type 17 E. rhusiopathiae was isolated from liver, lung, kidney, and lymph nodes of affected animals, which were in poor body condition, and suffering hair loss associated with tick (Dermacentor albipictus) infestations. Microscopic lesions consisted of mild, multifocal, necrotizing myocarditis, sarcocystosis, and lymph node atrophy. The bacterium may have gained entry to these animals via ingestion of, or percutaneous exposure to, contaminated water, or possibly by the bites of ticks. Malnutrition and tick infestation may have predisposed the animals to infection by this opportunistic pathogen.
1989年春季，在加拿大安大略省阿尔冈昆省立公园发现四只死亡驼鹿，其中三只被诊断为感染豕红斑丹毒丝菌败血症。从患病动物的肝脏、肺、肾和淋巴结中分离出17型豕红斑丹毒丝菌，这些动物身体状况不佳，伴有因蜱（白纹革蜱）寄生而导致的脱毛现象。显微镜下病变包括轻度、多灶性坏死性心肌炎、肉孢子虫病和淋巴结萎缩。该细菌可能通过摄入受污染的水、经皮接触受污染的水或可能通过蜱的叮咬进入这些动物体内。营养不良和蜱寄生可能使这些动物易受这种机会性病原体的感染。
