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 (B.C.), Mexico. In this study, Aggregata polibraxiona n. sp. was described from the cecum of O.bimaculatus collected from Bahia de …

Health of wild and reared Octopus vulgaris is threatened by the most dangerous parasite for the octopus, the protozoan coccidia Aggregata octopiana.This host-parasite relationship was studied to analyze the effect of A. octopiana on the cellular immune parameters of O. vulgaris.A. octopiana sporocysts infecting the digestive tract of octopuses were counted …

The coccidia genus Aggregata is responsible for intestinal coccidiosis in wild and cultivated cephalopods. Two coccidia species, Aggregata octopiana, (infecting the common …

ABSTRACT: Gamogony and sporogony of Aggregata octopianawere commonly observed during histological examination of the digestive tract of wild Octopus vulgaris from Ría de Vigo (NW Spain). A. octopiana infected noncuticularized caecum and intestine, and cuticularized oesophagus and

Octopus vulgaris infected with Aggregata octopiana were collected from an open-water culture system in the Ría of Aldán (NW Spain). Digestive tract infection values were determined with the use of a Neu chamber by counting the number of A. octopiana sporocysts. After determining enzyme activity values by the colorimetric Api-Zym system ...

Two coccidia species, Aggregata octopiana, (infecting the common octopus Octopus vulgaris), and A. eberthi, (infecting the cuttlefish Sepia officinalis), are identified in European waters. Extensive investigation of their morphology resulted in a redescription of A. octopiana in octopuses from the NE Atlantic Coast (NW Spain) thus clarifying ...

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 …

Gamogony and sporogony of Aggregata octopiana were commonly observed during histological examination of the digestive tract of wild Octopus vulgaris from Ria de Vigo (NW Spain). A. octopiana infected noncuticularized caecum and intestine, and cuticularized oesophagus and crop. Infection was also observed in the gills and in covering mesenterium ...

Aggregata octopiana was isolated from a pool of five infected octopuses (O. vulgaris) collected using traps by local fishermen in Ria de Vigo, Spain (24°14.09′N, 8°47.18′W). Aggregata oocysts were observed as white spots on the digestive tract with light microscopy. The oocysts were extracted from the caecum and intestine, and light ...

Currently, Aggregata octopiana Schneider is considered as the sole valid species infecting O. vulgaris (Gestal et al. 1999b), while A. eberthi Labbé is the one known to parasitize S. officinalis (Dobell 1925). Molecular analyses have allowed the assessment

A new species of parasitic Aggregata, Aggregata sinensis n. sp., is described from the octopuses Amphioctopus fangsiao (d'Orbigny, 1839–1841) and Octopus minor (Sasaki, 1920) (Mollusca: Octopodidae) in China based on morphological data and 18S ribosomal RNA (rRNA) gene sequences. The sexual gamogonic and sporogonic stages of the parasite were observed …
