title: Helical mycoplasmas (spiroplasmas) from Ixodes ticks.
abstract: A new spiroplasma isolated from Ixodes pacificus collected in Oregon was serologically and morphologically distinct from known spiroplasmas. The new spiroplasma could also be isolated in tick cell cultures. Discovery of a new fastidious mycoplasma in ticks offers opportunities to explore the possible role of these agents in human and animal diseases.
