Seasonal Dynamics of Conchophthirus acuminatus ( Ciliophora , Conchophthiridae ) Infection in Dreissena polymorpha and D . bugensis ( Bivalvia , Dreissenidae )
Although considerable research has been carried out on Dreissena spp., relatively little is known about the symbiotic organisms living within them. We report a two-year study of the dynamics of infection by the commensal ciliate Conchophthirus acuminatus in D. polymorpha and D. bugensis populations in the Dnieper River in the Ukraine and in four D. polymorpha populations in Belarus. C. acuminat...
متن کاملPseudodiarrhoea in zebra mussels Dreissena polymorpha (Pallas) exposed to microcystins.
Microcystins are produced by bloom-forming cyanobacteria and pose significant health and ecological problems. In this study we show that zebra mussels respond differently to different strains of Microcystis aeruginosa, and that a highly toxic strain causes zebra mussels to produce large quantities of mucous pseudofaeces, 'pseudodiarrhoea', that are periodically expelled hydraulically through th...
متن کاملUsing DNA barcoding to differentiate invasive Dreissena species (Mollusca, Bivalvia)
The zebra mussel (Dreissena polymorpha) and the quagga mussel (Dreissena rostriformis bugensis) are considered as the most competitive invaders in freshwaters of Europe and North America. Although shell characteristics exist to differentiate both species, phenotypic plasticity in the genus Dreissena does not always allow a clear identification. Therefore, the need to find an accurate identifica...
متن کاملBacterial Endocytobionts within Endosymbiotic Ciliates in Dreissena polymorpha (Lamellibranchia: Mollusca)
This paper documents a multi-level microcosm system: Dreissena-ciliates-bacteria-viruses. In the first comprehensive investigation of endocytobionts present in the cytoplasm of endosymbiotic ciliates from mussels, bacteria are described from Conchophthirus acuminatus and an undescribed Ophryoglena sp. species which are, respectively, commensal and parasitic in the freshwater bivalve Dreissena p...
متن کاملCytogenetic characterization of the Zebra Mussel Dreissena polymorpha (Pallas) from Miedwie Lake, Poland.
Cytogenetic characterization of D. polymorpha was carried out using banding techniques such as C-banding, fluorochrome CMA3 and silver nitrate treatment. The diploid chromosome number of both investigated D. polymorpha forms (typical and albinotic) was the same 2n = 32 (NF = 56). The karyotype consisted of 5 pairs of metacentric, 7 pairs of submetacentric and four pairs of subtelo-acrocentric c...
