    Abstract:
    The success of antimicrobial therapy depends on effective prescription of antibiotics. Assessment of clinical isolates using rapid antimicrobial susceptibility tests allows effective microbiological therapy to be commenced in a timely manner. However, conventional antimicrobial susceptibility testing is time-consuming and laborious. In the present study, we employed stuffer-free multiplex ligation-dependent probe amplification (MLPA) coupled with analysis of single-strand conformation polymorphisms, via high-resolution CE, to develop a multiplex antibiotic susceptibility test. Using this method, parallel analysis of specific genetic markers was employed to determine minimal inhibitory concentration values. The values derived using the stuffer-free MLPA method agreed with those estimated using a conventional broth dilution method. These findings indicate that the stuffer-free MLPA-based approach is a viable alternative to the conventional method.
