Testudo graeca tortoises were collected in the northern and southern Golan Heights (Israeli occupied territory of south Syria), and various locations in Israel and Palestine. Hyalomma aegyptium ticks were found only on Golan Height tortoises, and only the tortoises and ticks from the northern Golan Heights were infected with Hemolivia mauritanica. Tortoises became infected after ingesting infected ticks. Male ticks carrying sporocysts, which remain attached to tortoises for extended durations, apparently served as the source for dissemination of new infections among tortoises. Sporogenesis followed the pattern observed in the two other known species of Hemolivia, though there was some evident variation in fine-structural detail. The sutural slit detected in the H. mauritanica mature sporocyst wall was reminiscent of the suture characteristic of Coccidia of heterothermic vertebrate hosts; it could be a common ancestral character for both hemogregarines and Coccidia.
Résumé
Des spécimens de la tortue Testudo graeca ont été collectés dans les parties nord et sud des hauteurs du Golan, et en divers endroits d’Israel et de Palestine. Des tiques de l’espèce Hyalomna aegyptium furent trouvées sur les tortues des hauteurs du Golan, mais seules les tiques et tortues de la partie nord étaient infectées par Hemolivia mauritanica. L’infection des tortues était consécutive à l’ingestion de tiques. Des tiques mâles, porteuses de sporocystes, et fixées aux tortues pendant de longues périodes, étaient apparemment la source de dissémination de nouvelles infections parmi les tortues. La sporogenèse, conforme à celle décrite chez les deux autres espèces connues du genre Hemolivia, présentait cependant quelques différences au niveau ultrastructural. L’arête suturale du sporocyste mature d’H. mauritanica évoquait la suture caractéristique des coccidies d’hôtes vertébrés hétérothermes ; cette ressemblance suggère qu’il s’agit d’un caractère ancestral commun aux hémogrégarines et aux coccidies.
