Rhipicephalus sanguineus ticks transmit Ehrlichia canis, the etiologic agent of canine ehrlichiosis. In experimentally infected ticks, only p30-10 transcript was detected among 22 p30 paralogs encoding immunodominant major outer membrane P30 proteins of E. canis. The present study revealed transcription of p30-10 by E. canis in naturally infected ticks and sequence conservation of p30-10 genes for E. canis from diverse geographic regions.
