NTM diversity among outdoor beach showerhead biofilms (SHB) compared to indoor household SHB. (A) Examples of outdoor beach and indoor household showerheads (red circles, respectively) that were sampled in this study. (B) Beach SHB (n = 8/61) were less likely to be NTM culture positive than indoor SHB (n = 55/123). (C) Breakdown of the NTM species identified between outdoor beach SHB compared to indoor household SHB. (D) Inset box: No significant difference between M. chimaera recovery from either SHB type. N.S. = not significant. Phylogenetic analyses of respiratory and environmental SHB M. chimaera isolates based on rpoB gene sequencing.
