Bonamia exitiosus n. sp. (Haplosporidia) infecting flat oysters Ostrea chilensis in New Zealand.
Bonamia sp. is a pathogenic parasite that occurs in the haemocytes of dredge oysters Ostrea chilensis Philippi in New Zealand. Ultrastructurally it resembles other haplosporidians in the possession of haplosporosomes, haplosporogenesis, persistence of mitotic microtubules during interphase and of the nuclear envelope during mitosis, and occurrence of a diplokaryotic or multi-nucleate plasmodial...
متن کاملSouthern hemisphere mollusc diseases and an overview of associated risk assessment problems.
In Australia and New Zealand, Bonamia sp. causes epizootics in flat oysters (Tiostrea chilensis, Ostrea angasi); Marteilia sydneyi and Mikrocytos roughleyi cause mortality in farmed rock oysters (Saccostrea commercialis); and Perkinsus olseni is pathogenic in abalone (Haliotis spp.). Marteilia lengehi, Marteilioides branchialis, other Marteilioides spp. and two species of Haplosporidium are reg...
متن کاملSpore ornamentation of Minchinia occulta n. sp. (Haplosporidia) in rock oysters Saccostrea cuccullata (Born, 1778).
A Minchinia sp. (Haplosporidia: Haplosporidiidae) parasite was identified infecting rock oysters and morphologically described by Hine and Thorne (2002) using light microscopy and transmission electron microscopy (TEM). The parasite was associated with up to 80% mortality in the host species and it is suspected that the parasite would be a major impediment to the development of a tropical rock ...
متن کاملSpore ornamentation of Haplosporidium hinei n. sp. (Haplosporidia) in pearl oysters Pinctada maxima (Jameson, 1901).
An infection of pearl oysters, Pinctada maxima, attributed to a Haplosporidium sp. by Hine and Thorne (1998) has been detected on 3 occasions and is considered to represent a serious concern to the pearling industry in Australia. The spore ornamentation of the parasite was determined by scanning electron microscopy and transmission electron microscopy. Spores of the parasite were pleomorphic, o...
