title: A rickettsia-like organism from Ixodes uriae ticks collected on the Kerguelen Islands (French Subantarctic Territories).
abstract: A rickettsia-like microorganism was isolated in suckling mice from Ixodes uriae ticks collected from penguins breeding on Mayes Island, Kerguelen Archipelago, French Subantarctic Territories. At isolation, this agent mimicked a tick-borne arbovirus. Finally, electron microscopy studies of infected suckling mouse livers showed the presence of inclusions filled with pleomorphic microorganism in the cytoplasm of some hepatocytes, sometimes dividing by binary fission and thus of obviously non-viral nature. No firm serological relationship was demonstrated with Chlamydia psittaci, C. trachomatis, C. pneumoniae, Coxiella burnetti, Cowdria ruminentium, Ehrlichia canis, E. phagocytophila, E. risticii or the WSU/1044 agent. The exact taxonomic position of the "Mayes" agent remains to be clarified.
