Abstract
Data concerning serological classification of spiroplasmas are in good agreement, but slightly different numerical designations have been given to existing groups. It is proposed that a standardized system be adopted based on information developed mainly by the IRPCM working team on spiroplasmas. The type species (Spiroplasma citri) should be redefined to include only the agent of citrus stubborn disease (subgroup I-1). Six other subgroups, including three proposed by Bové et al. in this volume (I-5, I-6, and I-7), are members of the Group I complex. Because subgroups I-1, I-2, and I-3 (1) show significant reciprocal differences in DNA-DNA homology and two-dimensional electrophoretic protein profiles, (2) occupy exclusive habitats, (3) are each associated with important diseases, and (4) consist of clusters of very similar or identical strains, it is suggested that Latin binomials could be assigned to subgroups I-2 and I-3. It is proposed that those criteria could serve as general guidelines for consideration of subgroups for species status in the class Mollicutes. The I-4 subgroup is assigned an uncertain status, pending comparisons with the LB-12 (I-5), M55 (I-6), and N525 (I-7) subgroups. To previously described serogroups we add the CN-5 Cotinus beetle spiroplasma (IX), the AES-1 mosquito strain (X), and the MQ-4 Monobia strain (XI).
