dc.description.abstract | Both <i>Mycobacterium</i> spp. and <i>Methylobacterium</i> spp. are opportunistic premise plumbing pathogens that are found on pipe surfaces in households. However, examination of data published in prior microbiological surveys indicates that <i>Methylobacterium</i> spp. and <i>Mycobacterium</i> spp. tend not to coexist in the same household plumbing biofilms. That evidence led us to test the hypothesis that <i>Methylobacterium</i> spp. in biofilms could inhibit the adherence of <i>Mycobacterium avium</i>. Measurements of adherence of <i>M. avium</i> cells to stainless steel coupons using both culture and PCR-based methods showed that the presence of <i>Methylobacterium</i> spp. biofilms substantially reduced <i>M. avium</i> adherence and vice versa. That inhibition of <i>M. avium</i> adherence was not reduced by UV-irradiation, cyanide/azide exposure, or autoclaving of the <i>Methylobacterium</i> spp. biofilms. Further, there was no evidence of the production of anti-mycobacterial compounds by biofilm-grown <i>Methylobacterium</i> spp. cells. The results add to understanding of the role of microbial interactions in biofilms as a driving force in the proliferation or inhibition of opportunistic pathogens in premise plumbing, and provide a potential new avenue by which <i>M. avium</i> exposures may be reduced for at-risk individuals. | en |
