'Who's who' in renal sphaerosporids (Bivalvulida: Myxozoa) from common carp, Prussian carp and goldfish--molecular identification of cryptic species, blood stages and new members of Sphaerospora sensu stricto.

摘要: Myxozoans are a group of diverse, spore-forming metazoan microparasites bound to aquatic environments. Sphaerospora dykovae (previously S. renicola) causes renal sphaerosporosis and acute swim bladder inflammation (SBI) in juvenile Cyprinus carpio carpio, central Europe. A morphologically similar species with comparably low pathogenicity, angulata has been described from C. c. Carassius auratus gibelio. To clarify uncertainties ambiguities taxon identification these hosts we decided re-investigate differences spore morphology using statistical approach, combination SSU LSU rDNA sequence analyses. We found that developing spores cannot be distinguished designed duplex PCR assay for the cryptic demonstrated is specific whereas infects a. The molecular myxozoan blood stages common carp goldfish, which had previously ascribed spp. showed approximately 75% were non-sphaerosporid coelozoic infecting cyprinids more than 10% an alien species, Myxobilatus gasterostei, sticklebacks. hereby report non-selective host invasion multi-species infections, whose role SBI still requires clarification.
