The production of oligoclonal, polyspecific immunoglobulin G is characteristic of multiple sclerosis (MS), yet no pathogen has been identified as an infectious agent. Recent studies have proposed Acinetobactercalcoaceticus and Pseudomonas aeruginosa as candidate organisms, on the basis of a sequence homology between a bacterial enzyme and bovine myelin… (More)

In both instances, diagnosis was rapidly facilitated by 16S rRNA gene sequencing of blood culture isolates. To the best of our knowledge, we believe that our case is the first presentation of N. cyriacigeorgica… (More)
