Examination of the therapeutic effect of EC-CapsidCas13a-blaIMP-1 using a Galleria mellonella infection model. Administration of EC-CapsidCas13a-blaIMP-1 (MOI 100) into G. mellonella larvae infected with R10-61 (carbapenem-resistant clinical isolates of E. coli carrying blaIMP-1) significantly improved host survival compared to controls, EC-CapsidCas13a-nontargeting (p = 0.044), and phosphate-buffered saline (PBS; p = 0.0016). The p-value between two groups infected with R10-61, and treated with EC-CapsidCas13a-nontargeting and PBS was 0.30. The p-values are calculated by log-rank test. The results are presented as the aggregate values of three independent experiments performed using ten larvae per group. Source data are available in the Source Data file.
