The vast majority of antimicrobial agents are prescribed empirically — therapy that is initiated without knowledge of the specific infecting pathogen, but generally based on several important variables. These include site and type of infection, presenting symptoms, patient history and local antimicrobial resistance patterns. Additional reasons for empiric prescription include relieving symptoms...
Salt sensitivity of antimicrobial peptides poses a major obstacle in their development as novel antibiotics. Here we report the use of helix-capping motifs to confer salt resistance upon helical antimicrobial peptides. The helical content of the template peptide [RLLR](5) was almost completely destroyed at salt concentrations over 200 mm NaCl, leading to a 8-32-fold decrease in antimicrobial ac...
BACKGROUND Bacteremia due to Enterococcus faecalis is usually caused by strains resistant to most antibiotics. Effective management of the disease is dependent on rapid detection and characterization of the bacteria, and determination its sensitivity pattern to antimicrobial drugs. The aim of this study was to investigate a more rapid and reliable assay for simultaneous diagnosis of enterococca...
Two methods for determining the sensitivity of Haemophilus ducreyi to antimicrobial agents were compared; an agar dilution method and the Etest. The MICs of seven antimicrobial agents; penicillin V, ampicillin, trimethoprim, tetracycline, chloramphenicol, erythromycin and ciprofloxacin were determined for 20 strains of H. ducreyi. The MICs determined with the Etest and with the agar dilution me...
Increasing antimicrobial resistance to key antibiotics in Helicobacter pylori has become a main cause of treatment failures in many countries, including Vietnam. For this reason it is advisable to perform antimicrobial sensitivity tests to provide more focused regimens for H. pylori eradication. However, this approach is generally unavailable for H. pylori in Vietnam and the selection of treatm...
