TLDR
A systematic review of the parasites, pathogens and commensals of the edible cockle and of the lagoon cockle has been completed, providing information on the individual and population effects of these conditions as well as providing suggestions for future research.Abstract:
A systematic review of the parasites, pathogens and commensals of the edible cockle (Cerastoderma edule) and of the lagoon cockle (Cerastoderma glaucum) has been completed. A total of 59 different conditions have been reported throughout the range of both of these hosts; of these 50 have been reported in edible cockles, and 28 in lagoon cockles. Cockles are hosts to viruses, bacteria, fungi (including Microsporidia), Apicomplexa, Amoeba, Ciliophora, Perkinsozoa, Haplosporidia, Cercozoa, Turbellaria, Digenea, Cestoda, Nematoda, Crustacea and Nemertea. A number of these have been reported sporadically although they may be associated with mortalities. In particular, mortalities have been associated predominately with digeneans and some protistan infections. In many cases pathology is marked in affected animals and parasites have been shown to reduce fecundity, alter burrowing behaviour and limit growth. This review provides information on the individual and population effects of these conditions as well as providing suggestions for future research. In particular, there has been a lack of taxonomic rigour applied to many studies and as a result there are a number of erroneous host records. There is a need to re-describe a number of parasite species and to determine the life cycle of those considered to be important mortality drivers.read more

A review of the biology of European cockles ( Cerastoderma spp.)
TL;DR: The biology of the two main cockle species Cerastoderma edule and C. glaucum found in coastal areas around the north-east Atlantic from Norway to Morocco and through the Baltic, Mediterranean and Black Sea is examined and an assessment of future climate change scenarios on cockles is assessed.

Lineage-specific molecular probing reveals novel diversity and ecological partitioning of haplosporidians
Hanna Hartikainen,Oliver S. Ashford,Cédric Berney,Beth Okamura,Stephen W. Feist,Craig Baker-Austin,Grant D. Stentiford,David Bass +7 more
TL;DR: High frequencies of haplosporidian lineages in the water column provide the first evidence for life cycles involving planktonic hosts, host-free stages or both and emphasises the importance of lineage-specific approaches for studying these highly divergent and diverse lineages.

Mass mortalities in bivalve populations: A review of the edible cockle Cerastoderma edule (L.)
TL;DR: The importance of linked site-specific scientific investigations and laboratory-based experiments to fill the gaps in current understanding of mass mortalities in bivalve species is highlighted as necessary to take account of both local extrinsic and intrinsic factors.

Cockle infection by Himasthla quissetensis - I. From cercariae emergence to metacercariae infection
Xavier de Montaudouin,Hugues Blanchet,Céline Desclaux-Marchand,Nicolas Lavesque,Guy Bachelet +4 more
TL;DR: This study highlights the importance of water temperature and light in stimulating cercariae emergence which is closely related to the occurrence of cockle infection and suggests that other factors contribute to infestation variability.

Keys to the Trematoda
TL;DR: This volume covers five superfamilies within the Order Plagiorchiida and the family Didymozoidae, with keys for their identification at the family, subfamily and generic levels.

Microsporidia are related to Fungi: Evidence from the largest subunit of RNA polymerase II and other proteins.
TL;DR: Phylogenetic analyses of RPB1 sequences strongly support the notion that Microsporidia are not early-diverging eukaryotes but instead are specifically related to Fungi, and reexamination of elongation factors EF-1alpha and EF-2 sequence data show support for an early (Archezoan) divergence of these amitochondriate protists to be weak and likely caused by artifacts in phylogenetic analyses.

Chlamydiae as Symbionts in Eukaryotes
TL;DR: Several chlamydia-like bacteria have been described as symbionts of free-living amoebae and other eukaryotic hosts, contributing to a broader understanding of chlamydial biology and to novel insights into the evolution of these unique microorganisms.
