Multilocus sequence analysis (MLSA) in prokaryotic taxonomy

Systematic and Applied Microbiology, 2015
To obtain a higher resolution of the phylogenetic relationships of species within a genus or genera within a family, multilocus sequence analysis (MLSA) is currently a widely used method. In MLSA studies, partial sequences of genes coding for proteins with conserved functions ('housekeeping genes') are used to generate phylogenetic trees and ...

T-cell receptor Vβ use predicts reactivity and tolerance to Mlsa- encoded antigens

Nature, 1988
T lymphocytes reactive with the product of the Mlsa-allele of the minor lymphocyte stimulating (Mls) locus use a predominant T-cell receptor beta-chain variable gene segment (V beta 6). Such V beta 6-bearing T cells are selectively eliminated in the thymus of Mlsa-bearing mice, consistent with a model in which tolerance to self antigens is achieved by ...

Evaluation of the use of multilocus sequence analysis (MLSA) to resolve taxonomic conflicts within the genus Marichromatium

Systematic and Applied Microbiology, 2010
Four species of marine purple sulfur bacteria of the genus Marichromatium have been validly described. A recent re-analysis of the 16S rRNA-based similarity and genomic DNA-DNA hybridizations (DDH) of the type strains [33] suggested that some of them are so closely related that they can be considered heterotypic synonyms.

MLSA: A link-state multipath routing algorithm

2013 IEEE Symposium on Computers and Communications (ISCC), 2013
High reliability is always pursued by network and protocol designers. Multipath routing can provide multiple paths for transmission and failover, and is considered to be effective in the improvement of network reliability. To compute multiple paths efficiently, we present MLSA, a tree based link-state multipath algorithm, to help a node to find ...

Macrophages and T cells do not express Mlsa determinants.

The Journal of Immunology, 1989
Abstract In order to test the tissue distribution of Mlsa determinants, we have generated highly purified stimulator cell populations. First, Mlsa expression in bone marrow derived macrophages (Mphi) of Mlsa genotype was tested in primary MLR and on Mlsa-specific T cell hybridomas (THy).

Mel Log Spectrum Approximation (MLSA) filter for speech synthesis

Electronics and Communications in Japan (Part I: Communications), 1983
AbstractThe spectral envelope of speech can be represented efficiently by the log magnitude spectrum on the nonlinear frequency scale, which is close to mel scale (called mel‐log spectrum). the mel cepstrum defined by its Fourier coefficients is also considered to have a suitable property as the parameter to represent the spectral envelope.

Neonatal tolerance induction to Mlsa. II. T cells induce tolerance to Mlsa.

Cellular immunology, 1988
We have investigated the ability of murine T cell lines to induce neonatal tolerance to Mlsa (minor lymphocyte stimulating). Mlsb mice were injected within 24 hr of birth with MHC (major histocompatibility complex) identical T cell lines generated by culturing responders from Mlsa strains with stimulators from Mlsb strains. Injected mice were tested at

Soluble Mlsa antigens: Stimulatory effect in vitro versus suppressive effect in vivo

Immunogenetics, 1984
Using a pair of congenic strains of mice differing only at the Mls haplotype (Mls locus and closely linked genes), BALB/c (Mlsb) and BALB.D2-Mlsa, we have compared the in vitro proliferative responses of Mlsb lymphocytes to Mlsa antigens presented on either lymph node cells (LNC) or peritoneal adherent cells (PAC).

Multi-locus Sequence Analysis (MLSA) of Edwardsiella tarda isolates from fish

Veterinary Microbiology, 2012
Edwardsiella tarda is an enteric fish pathogen that has caused significant economic losses in a range of fish species residing in diverse ecological conditions. Several molecular methods relying on DNA fingerprinting (RAPD, RFLP and ERIC-PCR) and the gyrB gene marker have been used to characterize E. tarda isolates.

Neonatal tolerance induction to Mlsa. I. Tolerance to Mlsa is restricted by shared MHC determinants.

Cellular immunology, 1988
In this paper we have examined the influence of MHC (major histocompatibility complex) on neonatal tolerance to Mlsa (minor lymphocyte stimulating). By employing a novel approach we have shown that tolerance to Mlsa is restricted by shared MHC determinants.
