Haplosporidium littoralis sp. nov.: a crustacean pathogen within the Haplosporida (Cercozoa, Ascetosporea) [PDF]
Diseases of Aquatic Organisms, 2013 Previously, we described the pathology and ultrastructure of an apparently asporous haplosporidian-like parasite infecting the common shore crab Carcinus maenas from the European shoreline. In the current study, extraction of genomic DNA from the haemolymph, gill or hepatopancreas of infected C.

Ephemeral detection of Bonamia exitiosa (Haplosporida) in adult and larval European flat oysters Ostrea edulis in the Solent, United Kingdom [PDF]
Journal of Invertebrate Pathology, 2020 The haplosporidian parasite Bonamia exitiosa was detected using PCR in four adult and six larval brood samples of the European flat oyster Ostrea edulis from the Solent, UK. This represents the second reported detection of this parasite along the south coast of England.

Diseases of Aquatic OrganismsBonamia (Haplosporida) are oyster parasites capable of devastating oyster populations. The near-circumglobal distribution of the host generalist B. exitiosa has previously been associated with the natural and anthropogenic dispersal of broadly distributed non-commercial oysters in the Ostrea stentina species complex.

European Journal of Protistology, 1987 Morphogenesis of the "spherulosome" (formerly termed the "spherule") of Haplosporidium lusitanicum is described. In the apical zone of the immature spore a very complex and irregular membranous system is formed. This membrane synthesis begins in a precise zone which we call the "membranous organizer region". Half way their maturation of the spore, this

Fine structural observations of the natural spore excystment of Minchinia Sp. (Haplosporida)
European Journal of Protistology, 1989 The ultrastructure of the sequential phases of the spore excystment and the earliest plasmodial development of the haplosporidian Minchinia sp., pathogenic to the Portuguese clam Ruditapes decussatus (Mollusca, Bivalvia), were observed. Before spore excystment the endosporoplasm became lighter and its typical structures were rendered more visible. Like

Diagnosis and prevalence of two new species of haplosporidians infecting shore crabs Carcinus maenas: Haplosporidium carcini n. sp., and H. cranc n. sp. [PDF]
Parasitology, 2020 This study provides a morphological and phylogenetic characterization of two novel species of the order Haplosporida (Haplosporidium carcini n. sp., and H. cranc n. sp.) infecting the common shore crab Carcinus maenas collected at one location in Swansea
