Abstract
- 13 pages, 6 figures, 2 tables<br />Coccidian parasites of the genus Aggregata are known to parasitize cephalopods as definitive hosts, however one of the genus members, A. octopiana, has shown an unresolved phylogeny within the same definitive host, the common octopus (Octopus vulgaris). Our study represents a large-scale investigation aimed at characterizing morphological traits and phylogeny of A. octopiana isolated from O. vulgaris inhabiting three distinct geographic areas of the central Mediterranean: The Adriatic, Ionian and Tyrrhenian Seas. The morphology of sporogonic stages of the parasite in octopus tissues was assessed by light and electron microscopy; molecular characterization has been carried out using the 18S rRNA locus. Our results support the hypothesis that two morphologically and genetically different A. octopiana infect O. vulgaris in the investigated areas of the Mediterranean Sea. Additional nuclear and mitochondrial markers for Aggregata should provide further information and better resolution of its phylogeny<br />This work has been initiated through the networking initiatives of the COST Action FA1301 (CephsInAction) and thanks to the support of a COST FA1301-Short Term Scientific Mission (P. Tedesco, from Italy to Vigo, Spain). The study has been supported through RITMARE Flagship project (MIUR-SZN) to PT and GF. G. Catanese would like to thank INIA for the INIA/CCAA research contract program
