High throughput sequencing (HTSeq) of small ribosomal subunit amplicons has the potential for a comprehensive characterization of microbial community compositions, down to rare species. However, the error-prone nature of the multi-step experimental process requires that the resulting raw sequences are subjected to quality control procedures. These(More)
Experiences with the thin-layer chromatography of mycobacterial lipids for the differentiation of the species M. avium and M. intracellulare are described. Details of the procedure used have been published in a recent paper. The 61 strains investigated belong to 16 different serotypes. Twenty of the 21 strains of M. avium present three distinct lipid(More)
Experiences with the analysis of mycobacterial lipids by means of thin-layer chromatography are described. The influence of different media used for the cultivation of the strains, the age of cultures and heating of the bacteria on the lipid patterns was investigated. 25 strains of rapid growers belonging to various species were examined by a definite(More)
Under conditions of the ultrasonic thermo aerosol the stability of selected drugs is investigated by estimation of their concentration and by spectrophotometric and thin-layer chromatographic analysis, respectively. Using an ultrasonic nebulizer USI 50 of the common production neither the spectrophotometric nor the thin-layer chromatographic analysis give(More)
Methodical prerequisites to the differentiation of mycobacteria using thin-layer chromatography of their lipids described. The results of the identification of 112 strains belonging to 22 different species of Runyon's groups II, and III and IV are presented indicating that the lipid analysis permits the subdivision of mycobacteria into more species than(More)
Experiences with the lipid analysis of scotochromogenic mycobacteria by means of thin-layer chromatography are described. Out of 18 strains of M. scrofulaceum 11 belong to the serotypes Lunning, Gause, and Scrofulaceum. The similarity of the lipid patterns of the M. scrofulaceum strains to the ones of the M. avium-M. intracellulare group supports the(More)
The community, the assemblage of organisms co-existing in a given space and time, has the potential to become one of the unifying concepts of biology, especially with the advent of high-throughput sequencing experiments that reveal genetic diversity exhaustively. In this spirit we show that a tool from community ecology, the Rank Abundance Distribution(More)
The behaviour os histamine, acetylcholine, mucosolvine, panthenol, prednisolute and dexamethasone is investigated under conditions of thermoaerosol in the USI 50. The concentration of the drug is estimated in the original solution, in the aerosol and in the solution remaining in the nebulizer by means of specific chemical methods. The concentration in the(More)
