| ultrastructure of mikrocytos mackini, the cause of denman island disease in oysters crassostrea spp. and ostrea spp. in british columbia, canada. | an ultrastructural study was carried out on mikrocytos mackini, the cause of denman island disease in pacific oysters crassostrea gigas in western canada. three forms were identified, quiescent cells (qc), vesicular cells (vc) and endosomal cells (ec). qc occurred in the vesicular connective tissue (vct), haemocytes (hyalinocytes), adductor and heart myocytes, and extracellularly. they had a central round to ovoid nucleus, < 7 cisternae of inactive nuclear membrane-bound golgi, few vesicles and ... | 2001 | 11558731 |
| molecular detection of the oyster parasite mikrocytos mackini, and a preliminary phylogenetic analysis. | the protistan parasite mikrocytos mackini, the causative agent of denman island disease in the oyster crassostrea gigas in british columbia, canada, is of wide concern because it can infect other oyster species and because its life cycle, mode of transmission, and origins are unknown. pcr and fluorescent in situ hybridization (fish) assays were developed for m. mackini, the pcr assay was validated against standard histopathological diagnosis, and a preliminary phylogenetic analysis of the m. mac ... | 2003 | 12803386 |
| molecular taxonomy of mikrocytos boweri sp. nov. from olympia oysters ostrea lurida in british columbia, canada. | mikrocytos mackini is a microcell parasite that usually infects crassostrea gigas distributed along the pacific northwest coast of north america. for many years, m. mackini was the only known species in the genus, but there have been multiple recent findings of genetically divergent forms of mikrocytos in different hosts and in distantly located geographic locations. this note describes m. boweri sp. nov. found in olympia oysters ostrea lurida collected from and native to british columbia, canad ... | 2014 | 25060498 |
