| Our understanding of the microcell oyster parasites of the genera Bonamia and Mikrocytos has expanded in recent years with the application of ultrastructural and especially molecular biological research approaches. Molecular phylogenetic analyses of SSU rRNA genes have united three species, Bonamia ostreae, Bonamia exitiosa, and Mikrocytos (now Bonamia) roughleyi, in a microcell clade within the Haplosporidia, supporting both early and recent ultrastructural observations. Ultrastructural and molecular phylogenetic evidence has emerged that Mikrocytos mackini, on the other hand, is a unique protist with unusual adaptations for a parasitic existence. DNA probes and polymerase chain reaction (PCR) assays promise new insights into the life cycles,... |

| Murine moncolonal and polyclonal antibodies to antigesn of Bonamia ostreae were assessed for serological comparaison of parasites associated with different geographical originns of flat oyster, Ostrea edulis, and with Tiostrea lutaria. All Bonamia isolates from O. edulis reacted similary with polyclonal and monoclonal antibodies. The parasite associed with Tiostrea lutaria which lacks reactivity with 20 B 2 MAB must be considered as a serologically distinct from of B. ostreae |

| The protist phylum Haplosporidia comprises over 40 described species with representatives infecting a range of mollusc hosts, including several ecologically and economically significant pathogens. Continuing exploration of haplosporidian diversity has added ten new species in recent years and brought the phylogenetics of the group into somewhat clearer focus, with monophyletic Bonamia and Minchinia lineages continuing to be supported. However, the addition of new sequences to phylogenetic analyses has left the paraphyletic genus Haplosporidium’s picture less resolved. It is not clear that even two genera will be enough to accommodate the species presently drawn to the Haplosporidium regions of the haplosporidian tree. In this review, we summarize recent... |
