Although bacterial assemblages are important components of soils in arid ecosystems, the knowledge about composition, life-strategies, and environmental drivers is still fragmentary, especially in remote high-elevation mountains. We compared the quality and quantity of heterotrophic bacterial assemblages between the rhizosphere of the dominant(More)
Rapidly growing mycobacteria (RGM) inhabit soil and water but certain strains represent a health risk for human and animals. Both clinical and soil RGM may be under selection pressure for resistance to tetracycline (TET) antibiotics, since tetracyclines are administrated to humans and farm animals, and TET residues enter soil through manuring; however,(More)
This retrospective study aims to identify and describe the problems associated with the laboratory and clinical diagnosis of leptospirosis. A total of 4,813 patients with suspected leptospirosis from an area of the Czech Republic, with a total population of 1.15 million, were examined during the period 2002-2010. Our study included only 855 patients: 545(More)
Due to molecular biology techniques such as 16S rRNA gene sequencing, the number of new bacterial species grows continuously. However, this taxonomical reorganization has to be followed by clinical and epidemiological studies. The clinical relevance of Actinomyces turicensis, first identified in 1995 by Wüst et al. (5), has not been solved yet.(More)
We found well-preserved, rocky artefacts that had been buried in the healing mud (fango) for more than 1,500 years at the Roman archaeological site at Varaždinske Toplice. This Roman pool with fango sediments and artefacts is fed from hot sulphidic springs. The fango exhibited nearly neutral pH, a high level of organic C, an elevated concentration of heavy(More)
