Brains, spinal cords, nerve roots, nerves and muscle tissues were removed from deer in southern New York State and examined for histologic evidence of infection by the causative agent of Lyme disease, Borrelia burgdorferi. There was no histologic evidence of this infection and only four of 26 deer had serologic evidence of past infection despite the fact that all were parasitized by the tick vector, Ixodes dammini. Of these ticks, 21% were carrying B. burgdorferi. In contrast, most of the deer had choroid plexitis. All but one of 48 deer tested were infected with Trypanosoma cervi, 20 of 24 deer had sarcocystis in skeletal muscles and two had dural lesions probably due to the nematode Pneumostrongylus tenuis. The causal relationship between choroid plexitis and trypanosomiasis is discussed.
从纽约州南部的鹿身上取出大脑、脊髓、神经根、神经和肌肉组织，检查是否有莱姆病病原体伯氏疏螺旋体感染的组织学证据。没有发现这种感染的组织学证据，26只鹿中只有4只具有既往感染的血清学证据，尽管所有鹿都被蜱虫媒介达氏硬蜱寄生。在这些蜱虫中，21%携带伯氏疏螺旋体。相比之下，大多数鹿患有脉络丛炎。48只接受检测的鹿中，除一只外全部感染了鹿锥虫，24只鹿中有20只骨骼肌中有肉孢子虫，两只鹿有硬膜病变，可能是由线虫细颈气囊线虫引起的。文中讨论了脉络丛炎与锥虫病之间的因果关系。
