[Evaluation of novel nucleic acid detection kit for ].

For diagnosis of infection, highly sensitive and rapid diagnosis is important. Because antibiotics are limited for the treatment of infection. In this study, we evaluated new rapid nucleic acid detection kit for . This kit does not require excessive pretreatment of specimens and molecular diagnosis of is possible within 40 min. Using 120 nasopharyngeal specimens, we compared this kit with a commercially available molecular diagnostic reagent (LAMP). 51 of 120 cases were positive, and the results of both assays were all consistent. In addition, sequencing of 23S rRNA gene was performed on 51 cases positive for . As a result, macrolide resistance mutation (2063A>G) was observed in 19 cases (37.3%). The gene mutations estimated by this kit coincided completely with the sequencing. In conclusion, new rapid nucleic acid detection kit could detect with the same sensitivity as other molecular diagnostics, in a simple process.
