The two spiroplasmas were serologically indistinguishable but were related to serogroup IV spiroplasmas, which had been previously isolated from flower surfaces and from insects. The isolates were distinct from the three previously established species of Spiroplasma and from other presently known serogroups. The G + C content of the DNA from strain B31 was 30 +/- 1 mol %. Both B31 and B39 strains were associated with a lethal infection (\"May disease\") of the honey-bee.

Among different species, these virulence plasmids showed unrelated endonuclease cleavage patterns, whereas hybridization experiments showed that homologous sequences were present throughout the molecules. These plasmids may therefore have derived from a common ancestor molecule which overcame evolutionary alterations in restriction sites. Furthermore, intraspecies and intraserotype comparison of these plasmids by endonuclease cleavage demonstrated highly conserved sequences.
