Acknowledgments: We thank Linde Stewart and Violet Han for expert assistance in rickettsial isolation and electron microscopy, respectively, herpetologists Simon Watharow and Angela Reid for their expertise in reptile trapping, and entomologists Ian Beveridge and Owen Seeman for their help with identification of the ticks, We also thank Robert and Anna Stewart, Tina Stenos, Moira Graves, and John Sanchez for their valuable contribution to the Flinders Island field trip.
Financial support: This project was supported in part by the 1999 Australian Society for Microbiology Research Trust Fellowship awarded to John Stenos.
