The work was aimed at performing long-term cultivation of primmorphs in vitro from freshwater sponge Lubomirskia baikalensis (Pallas 1776), collected from Lake Baikal, obtaining its long-term primmorph culture in both natural (NBW) and artificial (ABW) Baikal water and at identifying the impact of different environmental factors on formation and growth of(More)
Lake Baikal is rich in endemic sponge species, among them the arborescently growing species Lubomirskia baicalensis. During winter when the lake is covered by ice, this species reproduces sexually, reflecting a high metabolic activity. Throughout the year, L. baicalensis lives in association with dinoflagellates, which - according to the data presented(More)
A holdfast is a root- or basal plate-like structure of principal importance that anchors aquatic sessile organisms, including sponges, to hard substrates. There is to date little information about the nature and origin of sponges' holdfasts in both marine and freshwater environments. This work, to our knowledge, demonstrates for the first time that chitin(More)
The morphological description of morphogenesis accompanying primmorph formation from cell aggregates in the endemic Baikal sponge Lubomirskia baicalensis as well as the description of cell composition of these primmorphs was investigated. Development of small sponges from dissociated cells in L. baicalensis is a stepwise process that can be separated into(More)
Materials on Ixodes tick-borne borreliosis (ITB) for the period of 2000 - 2003 (i.e. 1,222 blood serum samples from patients with acute ITB and 629 patients with chronic ITB) were analyzed. The proportion of seropositive samples among those obtained from patients with acute and chronic ITB was determined with the use of the indirect immunofluorescence test.(More)
