Comparative genomic analysis of two putative novel Idiomarina species from hypersaline miocene deposits.

Background: Hypersaline habitats, as extreme environments, are a great source of well-adapted organisms with unique properties as they have evolved various strategies to cope with these extreme conditions. Bioinformatics and genomic mining may shed light on evolutionary relationships among them. Therefore, the aim of this study was to assess the biodiversity and especially the strategies evolved within the Idiomarina genus, with the primary focus on the taxonomy and genomic adaptations of two novel strains affiliated with Idiomarina genus isolated from unique environment - brines of two Early Miocene salt deposits.

Genomic insights into the adaptation of Acinetobacter johnsonii RB2-047 to the heavy metal-contaminated subsurface mine environment.

The subsurface mine environments characterized by high levels of toxic metals and low nutrient availability represent an extreme threat to bacterial persistence. In recent study, the genomic analysis of the Acinetobacter johnsonii strain RB2-047 isolated from the Rozália Gold Mine in Slovakia was performed. As expected, the studied isolate showed a high level of heavy metal tolerance (minimum inhibitory concentrations were 500 mg/L for copper and nickel, 1,500 mg/L for lead, and 250 mg/L for zinc).

Genetic Basis of sp. K1 Adaptation Mechanisms to Extreme Environmental Conditions.

Anthropogenic pollution often leads to the generation of technosols, technogenic soils with inhospitable conditions for all living organisms including microbiota. Aluminum production near Ziar nad Hronom (Slovakia) resulted in the creation of a highly alkaline and heavy-metal-rich brown mud landfill, from which a bacterial strain of a likely new species of the genus , sp. K1, was isolated.

Antibiotic Resistance and Genetic Variability of spp. from Wastewater Treatment Plant in Kokšov-Bakša (Košice, Slovakia).

This study investigated the genetic variability and antibiotic resistance of community depending on the stage of wastewater treatment in Kokšov-Bakša for the city of Košice (Slovakia). After cultivation, bacterial isolates were identified by matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS), and their sensitivity to ampicillin, kanamycin, tetracycline, chloramphenicol and ciprofloxacin was examined. spp.

High frequency of antibiotic tolerance in deep subsurface heterotrophic cultivable bacteria from the Rozália Gold Mine, Slovakia.

The Rozália Mine, with its long mining history, could represent an environmental threat connected with metal contamination and associated antibiotic tolerance. Metal and antibiotic tolerance profiles of heterotrophic, cultivable bacteria isolated from the Rozália Gold Mine in Hodruša-Hámre, Slovakia, and the surrounding area were analysed. Subsurface samples were collected from different mine levels or an ore storage dump.

Analysis of the bacterial community from high alkaline (pH > 13) drainage water at a brown mud disposal site near Žiar nad Hronom (Banská Bystrica region, Slovakia) using 454 pyrosequencing.

Brown mud, as a waste product of the industrial process of aluminum production, represents a great environmental burden due to its toxicity to living organisms. However, some microorganisms are able to survive in this habitat, and they can be used in bioremediation processes. Traditional cultivation methods have a limited capacity to characterize bacterial composition in environmental samples.

The Bacterial Population of Neutral Mine Drainage Water of Elizabeth's Shaft (Slovinky, Slovakia).

Although neutral mine drainage is the less frequent subject of the interest than acid mine drainage, it can have adverse environmental effects caused mainly by precipitation of dissolved Fe. The aim of the study was to characterize the composition of bacterial population in environment with high concentration of iron and sulfur compounds represented by neutral mine drainage water of Elizabeth's shaft, Slovinky (Slovakia). Direct microscopic observations, cultivation methods, and 454 pyrosequencing of the 16S rRNA gene amplicons were used to examine the bacterial population.

Occurrence of blood parasites and intensity of infection in Prunella modularis in the montane and subalpine zone in the Slovak Carpathians.

The objective of this study was to obtain primary information on the occurrence of blood parasites and intensity of infection in the Dunnock Prunella modularis in the montane region of Slovakia. Altogether 109 birds were examined during the years 2006-2010. The occurrence of Haemoproteus sp.

Yersinia species in the dunnock (Prunella modularis) in sub-alpine habitats of the Western Carpathians.

The study presents the prevalence of Yersinia species in dunnok Prunella modularis from the sub-alpine zone of the Western Carpathians. Bacteria were detected from cloacal and pharyngeal swabs from 97 specimens using PCR assay. Yersinia enterocolitica showed the highest prevalence (47.

Open field behavior and habituation in rats irradiated on the head with gamma-rays.

The goal of this work was to establish the effects of irradiation of the head with gamma-rays on selected forms of innate behavior, as well as on the habituation process to new environment in the open field test in rats. During a 5-day control period behavioral parameters reflecting motoric and explorative activities, as well as anxiety (6 parameters in total) were followed daily in 20 male Sprague-Dawley rats in an open field. Fourteen animals were repeatedly tested after irradiation of the head with a single dose of 10 Gy of gamma-rays.
