[Disorders of erythrocyte deformability in patients with acute suppurative-septic diseases of the lung and pleura]. / Narushenie deformiruemosti éritrotsitov u bol'nykh ostrymi gnoino-septicheskimi zabolevaniiami legkikh i plevry.

In 163 patients with acute suppurations of lungs and pleura a substantial reduction of deformability of erythrocytes was established. The maximum increased rigidity of blood red cells was noted at the peak of the pyo-destructive process and postoperative period as well as in the complicated course of the postoperative period. The curative plasmapheresis, general hyperbaric oxygenation exert positive influence upon plastic properties of erythrocytes.

[Three new species of brevibacteria--Brevibacterium antiquum sp. nov., Brevibacterium aurantiacum sp. nov. and Brevibacterium permense sp. nov]. / Tri novykh vida brevibakterii--Brevibacterium antiquum sp. nov., Brevibacterium aurantiacum sp. nov. i Brevibacterium permense sp. nov.

This work deals with the taxonomic study of 12 orange-pigmented bacteria isolated from permafrost sediments, rice plots, and soils contaminated with wastes from the chemical and salt industries, which were assigned to the genus Brevibacterium on the basis of phenotypic characteristics, as well as of some strains described previously as Brevibacterium linens. The study revealed three genomic species, whose members and the type strains of the closest species of Brevibacterium had DNA similarity levels between 24 and 59%. The strains of the genomic species differed from each other and from the known species of Brevibacterium in some physiological and biochemical characteristics, as well as in the sugar and polyol composition of their teichoic acids. The 16S rDNA sequence analysis confirmed the assignment of the environmental isolates to the genus Brevibacterium and showed the phylogenetic distinction of the three genomic species. The results obtained in this study allow three new Brevibacterium species to be described: Brevibacterium antiquum (type strain VKM Ac-2118T = UCM Ac-411T), Brevibacterium aurantiacum (type strain VKM Ac-2111T = NCDO 739T = ATCC 9175T), and Brevibacterium permense (type strain VKM Ac-2280T = UCM Ac-413T).

[Micromycetes and actinobacteria under conditions of many years of natural cryopreservation]. / Mikromitsety i aktinobakterii v usloviiakh mnogoletnei estestvennoi kriokonservatsii.

Almost all of the investigated samples of the Arctic and Antarctic permafrost sediments of different genesis with ages from 5-10 thousand to 2-3 million years were found to contain viable micromycete and bacterial cells. The maximum amounts of viable cells of fungi (up to 10(4) CFU/g air-dried sample) and bacteria (up to 10(7)-10(9) CFU/g air-dried sample) were present in fine peaty sediment samples taken from different depths. The identified micromycetes belonged to more than 20 genera of the divisions Basidiomycota, Ascomycota, and Zygomycota, and some represented mitosporic fungi. Thawing the samples at 35 and 52 degrees C allowed the number of detected fungal genera to be increased by more than 30%. Aerobic heterotrophic prokaryotes were dominated by coryneform, nocardioform, and spore-forming microorganisms of the order Actinomycetales. Analysis of the isolated fungi and actinomycetes showed that most of them originated from the microbial communities of ancient terrestrial biocenoses.
