In this study, we generated a microsatellite-enriched genomic DNA library for Scophthalmus rnaxirnus, and then isolated and characterized 45 microsateIIite loci by genotyping 30 individuals. The observed number of alleles ranged from 2 to 19 with an average of 6.24, while the effective number of alleles ranged from 1.30 to 11.11 with an average of 3.66. The expected heterozygosities varied from 0.235 to 0.9254 and polymorphic information content ranged from 0.204 4 to 0.903 3, with an average of 0.622. Twelve loci deviated significantly from Hardy-Weinberg equilibrium, and no significant linkage disequilibrium was observed between any pair of loci after Bonferroni correction. In cross-species amplification, five flatfish species (Paralichthys lethostigma, Verasper rnoseri, platichthys stellatus, Hippoglossoides dubius and Cynoglossus semilaevis) showed at least one polymorphic locus. These polymorphic microsatellite loci should prove useful for population analysis of turbot and other related species.展开更多

The activities of amikacin in the presence of sub-lethal silver nitrate(15 μM) were tested for the combinational effects against multidrug resistant clinical isolates in vitro. Silver nitrate restored the susceptibility of drug-resistant Acinetobacter baumannii and methicillin-resistant Staphylococcus aureus to amikacin. It lowered the MICs of amikacin from 〉128 μg/mL to(2–16) μg/mL and 32 μg/mL, respectively, and lowered the MICs of amikacin on extended spectrum β-lactamase-producing Pseudomonas aeruginosa and Escherichia coli from(16–32) μg/mL and 16 μg/mL to(〈1–4) μg/mL and 〈1 μg/mL, respectively.展开更多
