C. difficile detection results for the 118 samples analysed by culture and 16S rRNA gene analysis. Grid detailing the detection results for the samples analysed by both methods. For classic microbiology, samples are positive if either direct or enrichment culture is positive. For 16S profiling, samples are positive if at least one sequence read is identical to C. difficile V1-V3 16S rDNA sequence. Red – negative sample; white – non-analysed sample; yellow – C. difficile positive culture; blue – C. difficile sequence detection and green – C. difficile positive for both methods
