“…regarding the seasonal variation in the prevalence of infection by this parasite in Mediterranean mussels, reports are contradictory. We have observed increased prevalence at the end of the autumn compared to that recorded during the summer, which is in agreement with the findings of robledo et al (1994b), but differs from the reports of other authors (González et al, 2005;Mladineo et al, 2012), who found the opposite. The results can indicate that infection by this parasite may be dependent by various environmental parameters, which affect host-parasite relationship.…”

“…The present study did not indicate any difference in the prevalence of the infection by this organism between the two culture systems, which suggests that the polyps can be found in the entire water column at many depths. For both culture systems, prevalence of the infection was higher in October compared to that in July, finding which is in agreement with earlier studies by Piraino et al (1994Piraino et al ( ), rayyan et al (2004 and (Mladineo et al, 2012). The increase in the prevalence of infection may be associated with the seasonality of the population of polyps observed in Thermaikos gulf, as rayyan et al (2004) have suggested.…”

For the production of the Mediterranean mussel, Mytilus galloprovincialis, two systems are used in Greece, the ‘long-line’ and the ‘on-table’ system. In the present study, effects of farming system on prevalence of infection by some parasites of Mediterranean mussels were investigated. Three mussel culture sites, located at Thermaikos gulf, with similar profiles, where both farming systems are practiced, were selected. Two samplings took place in 2008, one in July and one in October. From each site, 30 mussels per culture system were collected. From each mussel, tissue samples from the visceral mass, mantle and gills were collected and examined histologically for the presence of any parasites. Number of mussels parasitized by at least one parasitic species was substantially increased in mussels cultured with the ‘on-table’ system. In particular, prevalence of infection by Urastoma cyprinae and Marteilia spp. was substantially increased in mussels cultured with the ‘on-table’ system, while no relation between farming system and prevalence of infection by Eugymnanthea inquilina was observed. Prevalence of infection by Myticola intestinalis, Steinhausia mytilovum and Proctoeces maculatus was considerably low in both culture systems. In addition, in both culture systems, number of the mussels infected by E. inquilina and U. cyprinae was substantially increased in October, while an opposite trend was noted for Marteilia spp.

“…The turbellarian U. cyprinae has been reported from the gills of M. galloprovincialis in the Black Sea (Murina & Solonchenko, 1991), on the French Mediterranean coast (Noury-Srairi et al ., 1990; Robledo et al ., 1994), on the Galician region, NW Spain (Robledo et al ., 1994), on the Pacific coasts of North America (Caceres-Martinez et al ., 1998) and in the Adriatic Sea (Westbald, 1955; Mladineo et al ., 2012). Caceres-Martinez et al (1998) reported infestation prevalence ranges from 10 to 87% and a mean number of 1.9 per infested M. galloprovincialis in the Pacific coasts of North America.…”

This is the first comprehensive research study on the parasites of Mytilus galloprovincialis collected from the Sinop coasts of the Black Sea and their relationships with several environmental and biotic factors. A total of 1740 mussels were collected monthly at three sampling localities representing different ecosystems in the period between August 2012 and July 2013 and examined for parasites. Identified parasites were Nematopsis legeri, Peniculistoma mytili, Urastoma cyprinae, Parvatrema duboisi and Polydora ciliata. Infection prevalence (%), mean intensity and mean abundance values of each parasite species were calculated according to season, sampling localities and length classes of mussel. Nematopsis legeri was the most prevalent species (32.5%), followed by Pe. mytili (6.70%), U. cyprinae (6.30%), Pa. duboisi (4.50%) and Po. ciliata (2.20%). Nematopsis legeri and Parvatrema duboisi had their highest infection prevalence and intensity values in sampling locality III where secondary hosts present to complete their life cycle and larger sized mussels had higher parasite loads. Statistically significant differences were determined in the prevalence of infection and intensity values among seasons, length classes of mussel and sampling localities of each parasite species. The present study provided valuable information on mussel parasites and their relationships with host length, seasons and ecology.

Ontogeny of bivalve immunity: assessing the potential of next‐generation sequencing techniques

Living organisms are constantly evolving to secure their survival via adaptations at the molecular and cellular level. Most marine bivalves have microscopic planktonic larval stages until settlement to the benthic environment. These pelagic stages are generally more sensitive than their adult counterparts to environmental and pathogen threats. Adaptive capacities could improve survival of these early stages. Recent advancements in data mining and pipeline analysis should shed light on the currently unknown processes that occur during these first stages. Existing data on early stages are fragmented compared with the abundance of information available for adult. Exploring diversity through aquaculture and lessening the impact of common issues, for example, massive mortalities of larvae, especially within the current conditions of a changing climate, ultimately rests on our knowledge of the molecular processes responsible for phenotypic plasticity. Although it is somewhat difficult to assess immune mechanisms by tracking circulating immunocytes in larvae, studies on the development of immune processes are now feasible at the transcript level. Next-generation techniques offer outstanding solutions for wide-range transcriptome analysis. We present a short review of the early ontogeny of the immune system in marine bivalves, with particular focus on next-generation sequencing applications. Like all reviews of this nature, there is a trade-off between the depth of the coverage and the number of subjects discussed. We will thus restrict the scope to bivalve immunity and focus on the central concepts across a wide range of topics, that is, the ontogeny of immunity and advancements in molecular studies.
