·Background Octopus vulgaris is a highly valuable species of great commercial interest and excellent candidate for aquaculture diversification; however the octopus well being is impaired by pathogens of which the gastrointestinal coccidian parasite Aggregata octopiana is one of the most important The knowledge of the molecular mechanisms of the immune
·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
·Aggregata octopiana and Aggregata eberthi Apicomplexa Aggregatidae from the NE Atlantic coast using 18S rRNA sequences Sheila Castellanos Martíneza Marcos Prez Losadab Camino Gestala aInstituto de Investigaciones Marinas Consejo Superior de Investigaciones Científicas Eduardo Cabello 6 36208 Vigo Spain
Prevalence and distribution of the coccidian parasite Aggregata octopiana Protozoa Apicomplexa in common octopus Octopus vulgaris in the Mediterranean Spanish coasts were studied A total of 114 octopuses were sampled from 30 geographic sectors by trawl fleet and whitish macroscopic oocysts typical of A octopiana infection were recorded
·The eimeriorin coccidian Aggregata octopiana Apicomplexa Aggregatidae is known to heavily infect the digestive tract of octopus cuttlefish and squids Pascual et al 1996 This coccidiosis impairs the well being of cephalopods believed to cause a
2 ·Aggregata kudio Sepia elliptica Aggregata maxima Sergestes robustus Aggregata millerorum Octopus bimaculoides [13] Aggregata octopiana Octopus vulgaris [8] Aggregata patagonica Enteroctopus megalocyathus [14] Aggregata sagittata [15] Eupagurus
·The Apicomplexa Aggregata spp are intracellular parasites of cephalopods that infect the intestinal tract of commercially important species such as Octopus bimaculatus which sustains the octopus fishery in Baja California Mexico In this study Aggregata polibraxiona n sp was described from the cecum of collected from Bahia de
The SEM analysis of heavily parasitized tissue showed the surface topography of the host parasite in 1 Fig 1 Aggregata octopiana Oocyst containing several sporocysts observed under differential interference contrast microscopy DIC Nomarski 1 525x Ultrastructure of the sporogony of Aggregata octopiana from Octopus vulgaris teraction
·The coccidia genus Aggregata is responsible for intestinal coccidiosis in wild and cultivated cephalopods Two coccidia species Aggregata octopiana infecting the common octopus Octopus vulgaris and A eberthi infecting the cuttlefish Sepia officinalis are identified in European investigation of their morphology resulted in a redescription of A
