Figure 1

The Xpert MTB/RIF Ultra detection results (represented as mean Ct-values and interquartile ranges) of bronchial alveolar lavage fluids (BALF) and trunk washes (TW) collected from uninfected African elephants (n = 6) (BALF/TW—bottom lines) and rhinoceros (n = 3) (BALF—top three lines), experimentally spiked in duplicate with different concentrations (CFU/ml) of (a) M. tuberculosis H37Rv (30—2 and 0 CFU/ml) and (b) M. bovis SB0121 (1 × 106—30 and 0 CFU/ml), respectively. African rhinoceros BALF and African elephant BALF/TW samples were also spiked (in triplicate) with 1 × 106 CFU/ml of Mycobacterium avium and ‘MTB NOT DETECTED’ reported for all these samples.
