Helical Mycoplasmas (Spiroplasmas) from <i>Ixodes</i> 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.
