Figure 1From: Quantification of Mycobacterium avium subspecies in pig tissues by real-time quantitative PCRResponse of the Mycobacterium -specific qPCR assay to M. avium subspecies avium ATCC 25291 cells in pig liver. Mycobacterial DNA was quantified in five parallel extracts of pig liver spiked with M. avium subspecies avium (1 × 104 to 1 × 107 bacteria per gram). Open symbols denote qPCR results below the detection limit (4 × 104 mycobacteria per gram).Back to article page
