Sixteen Salmonella strains resistant to nalidixic acid isolated from kimbab, the most popular ready-to-eat (RTE) food in Korea, and chicken meat were selected for this study. The resistant strains were shown to have high minimal inhibitory concentrations (MICs) against nalidixic

The role of the AcrAB-TolC pump in macrolide and ketolide susceptibility in Escherichia coli and Enterobacter aerogenes was studied. Efflux pump inhibitor restored erythromycin, clarithromycin, and telithromycin susceptibilities to multidrug-resistant isolates. No modification of telithromycin accumulation was detected in E.
The subcellular distribution of soluble and membrane-bound Arg-beta-naphthylamide-hydrolyzing activities was studied in the left and right rat brain during development and aging. During development, the soluble activity was heterogeneous, whereas adult animals showed the highest activity in the synaptosomal fraction.

The aminopeptidase activity of arginine-utilizing mycoplasmas was investigated with 20 aminoacyl beta-naphthylamide substrates. High levels of arginyl-beta-naphthylamide hydrolysis were demonstrated in 6 of 11 species when extracts of concentrated washed organisms were used. Relatively low arginine aminopeptidase activity was demonstrated
The substrate specificity of rat testicular and epididymal peptidase was investigated using chromogenic substrates, D. L-alanine-, L-arginine-, gamma-N-L-glutamine-, L-leucine-, D. L-methionine-, alpha-N-benzoyl-D. L-arginine-, and N-benzoyl-L-leucine-beta-naphthylamide. The histochemical distribution of peptidase activity demonstrated with these substrates was also investigated in the
