| description | Abstract Simple and fast diagnosis of Citrobacter freundii which is an important cause of nosocomial infection in human is crucial to achieve early treatment. We have developed and evaluated an optical LAMP-based biosensor for the visual detection of C. freundii for the first time. The efficiency of the assay was investigated and compared to PCR method. The selectivity and specificity of the biosensor were analyzed using Morganella morganii, Enterobacter aerogenes, Pseudomonas aeruginosa, Yersinia enterocolitica, Shigella sonnei, Serratia marcescens, Burkholderia cepacia and Klebsiella pneumoniae and a mixed-culture medium. Endpoint analysis using hydroxy naphthol blue was applied, and the color change to sky blue and no color change from violet indicated positive and negative results, respectively. The absorption at 650 nm was measured 0.39 for the positive sample, while the mean absorption of the test samples, including water, was 0.23. The specificity of the method was equal to that of PCR. However, the sensitivity was determined as 12.24 fg/µL of the genomic content of C. freundii, higher than PCR assay. The developed LAMP-based method provided a rapid and accurate technique for molecular diagnostics of C. freundii, making it a suitable technique for point-of-care diagnostics in cases of urgent situations. |
