Significant changes have been made in the systematics of the genus Spiroplasma (class Mollicutes) since it was expanded by revision in 1987 to include 23 groups and eight sub-groups. Since that time, two additional spiroplasmas have been assigned group numbers and species names. More recently, specific epithets have been assigned to nine previously designated groups and three sub-groups. Also, taxonomic descriptions and species names have been published for six previously ungrouped spiroplasmas. These six new organisms are: Spiroplasma alleghenense (strain PLHS-1T) (group XXVI), Spiroplasma lineolae (strain TALS-2T) (group XXVII), Spiroplasma platyhelix (strain PALS-1T) (group XXVIII), Spiroplasma montanense (strain HYOS-1T) (group …

Spiroplasma group XIV strain EC-1T and other isolates from the lampyrid beetle Ellychnia corrusca form a serogroup with tabanid spiroplasma strains (TC-1 and TS-1). It was hypothesized that similarities among these strains reflect a transmission cycle in which lampyrid beetles serve as overwintering hosts and tabanid adults become infected and transmit a homogeneous population of spiroplasma strains during spring, summer and autumn. In the present study, variations in restriction fragment length patterns suggest the presence of multiple genovars. Genotypic analysis may therefore be a companion to serology in elucidating spiroplasma diversity, and may provide clues to strain host range.
