Detection of vancomycin resistance genes combined with typing of Enterococci by means of multiplex PCR amplification and multiple primer DNA sequencing.
A multiplex PCR assay for the detection of vancomycin resistance (van) genes in enterococci was established. Primers targeting the 16S rRNA gene were included in the reaction mixture. Multiple-primer DNA sequencing of the PCR products provided species identification through partial nucleotide sequences of 16S rRNA genes, as well as confirmation of the correct identification of vanA, vanB, vanC-1, and vanC-2/3 genotypes. Thirty-nine enterococcal clinical isolates and type strains were examined for the presence of vancomycin resistance determinants. Twelve other isolates from a clinical reference collection (some of them having vanA, vanB, vanC-1, or vanC-2/3 genotypes) were used as controls. Hybridization and partial DNA sequence analysis of multiplex PCR products revealed that none of the clinical isolates had a vanA genotype and only one had a vanB genotype. vanC-1 was found in three clinical isolates, and vanC-2/3 in one. Results obtained with the reference and type strains were in agreement with earlier results.

A program for sampling, assessment of stationarity and variability analysis of neuronal spike trains, run under control of a time-sharing system.
A system has been developed for off-line analysis of discharge characteristics of continuously firing nerve cells. The programs, which are mainly written in FORTRAN IV, determine mean firing rates, variability and other parameters of the impulse activity, and construct interspike interval histograms. They are run under time-sharing on a small laboratory computer. To disclose possible non-stationarities in the data all interspike interval samples are analysed with the non-parametric Kolmogorov-Smirnov test. This test is very powerful in detecting any differences between two samples and is still very easy to implement in programming. Raw data and computed statistics are stored in random access data files.
