We studied the significance of particular eis mutations on M. tuberculosis drug resistance by using a specialized transduction strategy. Recombinant strains harboring eis mutations C-14T C-12T, and G-10A exhibited kanamycin resistance with MICs of 40, 10, and 20 μg/ml respectively, while recombinant strains harboring C-14G and C-15G were kanamycin susceptible (MIC 2.5-5 μg/ml). All of the tested eis mutants remained amikacin susceptible (MIC 0.5-4 μg/ml). The identification of specific eis mutations is needed for accurate genotypic susceptibility testing for kanamycin...

Erysipelothrix rhusiopathiae, a Gram-positive bacillus, is reported to cause for cutaneous infections and endocarditis. We report a case of E. rhusiopathiae bacteremia without severe clinical illness. The patient, a 74-year-old man, is suffering from a chronic lymphoid leukemia (LLC). Following a trauma, the patient developed a bruise on the left inch. Because the site of shock seemed clinically infected, oral amoxicilline-acid clavulanic (AAC) treatment was started after withdrawn 1 set of blood cultures. These blood culture specimens yielded a Gram-positive bacillus identified as E...

High mobility group box 1 (HMGB1) is a DNA-binding protein that facilitates gene transcription and may act extracellularly as a late mediator of inflammation. The roles of HMGB1 in the pathogenesis of the spiral ganglion neurons (SGNs) of the cochlea are currently unknown. In the present study, we tested the hypothesis that early phenotypical changes in the SGNs of the amikacin-poisoned rat cochlea are mediated by HMGB1. Our results showed that a marked downregulation of HMGB1 had occurred by completion of amikacin treatment, coinciding with acute damage at the dendrite extremities of the SGNs...
