Parasite of the Day: September 30 - Aggregata octopiana

 · Aggregata octopiana is a species of single-celled parasite that infects the common octopus, forming cysts in various parts of the body including the gills, digestive tract, and epidermis. The details of the parasite's life-cycle are currently not clear, though it is known to be a two-host life-cycle involving alternating phases of sexual and ...

Cysts were detected in 63% of 48 prawns (P. elegans) collected from Ría de Vigo, Spain [date not given]. Immunohistochemistry showed that in all the infected prawns tested, the cysts containing merozoites reacted positively to anti-A. octopiana sporocyst mouse serum but showed little reactivity to anti-A. eberthi sporocyst mouse serum.

Coccidial infection of the intestinal tract by Aggregata octopiana is very frequent in the common octopus (Octopus vulgaris), a marine species with great potential in aquaculture. Altered host-parasite relationship under intensive rearing conditions has been described resulting in hyperinfections that compromise the health and viability of the animal and may lead to condemnation for human...
