Amplified intergenic locus polymorphism as a basis for bacterial typing of Listeria spp. and Escherichia coli

Article Abstract:

Polymorphism was evaluated using 18 amplified intergenic locus polymorphism (AILP) sites among 28 strains of Listeria monocytogenes and 6 strains of Listeria spp. and 30 AILP markers among 27 strains of Escherichia coli. The AILP method was found to be rapid, simple, reproducible, and a low-cost method for initial bacterial typing that could serve as a basis for epidemiological investigation.

Triphenylmethane reductase from Citrobacter sp. strain KCTC 18061P: Purification, characterization, gene cloning, and overexpression of a functional protein in Escherichia coli

Article Abstract:

An enzyme is purified biochemically from Citrobacter sp. strain KCTC 1806P that is capable of decolorizing triphenylmethane dyes. The characterization, cloning of the gene encoding the triphenylmethane reductase (TMR) enzyme and its heterologous expression in Escherichia coli are reported.

The Listeria monocytogenes homolog of the Escherichia coli era gene is involved in adhesion to inert surfaces

Article Abstract:

The identification of two transposon-insertional mutants of Listeria monocytogenes is reported. Imol1462 is found to be the gene involved in adhesion contributing to the presence of Listeria monocytogenes on surfaces.
