We have determined and compared partial 16S rRNA sequences from 23 Lyme disease spirochete isolates and aligned these with 8 sequences previously presented. The 16S rRNA signature nucleotide compositions were defined for each isolate and compared with the genomic species signature nucleotide sets previously established. To identify positions truly indicative of species classification which coul...

Borrelia burgdorferi infection in horses is common in some areas of North America, yet the incidence of clinical disease has not been determined which makes Lyme disease in the horse controversial. Progress is being made, case-by-case, in defining the several clinical presentations of Lyme disease in adult horses. Current serologic tests are very sensitive and specific for detecting either prev...

INTRODUCTION Dermatomyositis has been described in the setting of lyme infection in only nine previous case reports. Although lyme disease is known to induce typical clinical findings that are observed in various collagen vascular diseases, to our knowledge, we believe that our case is the first presentation of acute lyme disease associated with amyopathic dermatomyositis, which was then follow...
