doi: 10.1016/j.juro.2010.09.022

Figure Lengend Snippet: Comparison of conventional and biosensor based culture susceptibility analysis of urine. Urine sample is first tested for presence and identity of pathogens. For detection of pathogens sensors are functionalized with capture oligonucleotides targeting 16S rRNA of E. coli, P. mirabilis, P. aeruginosa, Enterococcus spp., Klebsiella-Enterobacter group, Enterobacteriaceae group, universal eubacterial and negative control. Electrochemical detection of pathogen 16S rRNA hybridization with capture and detector probes provides culture data within 1 hour of urine sample collection. If pathogens are identified, level of 16S rRNA from sample incubated without and with antibiotic is quantified on biosensor providing susceptibility data within 3.5 hours of urine sample collection. In contrast to b-AST, conventional culture and susceptibility can take up to 72 hours.
