Overall, our data unveil a novel immunosuppressive mechanism of UreB during H. pylori infection, which may provide valuable clue for the optimization of H. pylori vaccine. The MYChrOme™ Culture Plate is a chromogenic media for the detection and differentiation of rapid-growing nontuberculous mycobacteria (NTM) in water, aided by MYCOn™ decontamination to reduce background microbiota. Evaluate the MYChrOme™ Culture Plates for the detection of rapid-growing NTM in potable and non-potable water as part of the AOAC Performance Tested Method SM program. Inclusivity and exclusivity of MYChrOme™ were evaluated with 50 target and 30 non-target organisms. Method robustness and lot stability of MYChrOme™ were analyzed. The candidate method was compared to a modified FDA Method US FDA-Isolation and Identification of Nontuberculous Mycobacteria in Tattoo Inks using an equivalency test. The matrix study consisted of artificially contaminated potable water and naturally contaminated non-potable water. Independent laboratory testing was conducted to verify method performance in non-potable water. The inclusivity of MYChrOme™ was 94% within one week, and 98% within two weeks. The exclusivity was 96% for untreated samples and 100% for treated samples. The candidate method remained statistically equivalent for robustness and a three-month shelf-life was confirmed. For both matrixes, the candidate and reference methods were not equivalent, with more colonies enumerated on the candidate method except for one contamination level of the potable matrix. The MYChrOme™ culture method can successfully detect and differentiate rapid-growing NTM in the matrixes tested, with sensitivity equivalent or higher than the reference method.
