Methylobacterium spp. are emerging opportunistic premise plumbing pathogens. Human infections linked to premise plumbing provide evidence of their routes of infection. Cells of a collection of representative strains of different Methylobacterium species were tested for hydrophobicity by contact angle, adherence and biofilm formation on different plumbing materials, and temperature tolerance (50–60 °C); characteristics shared by OPPPs. Methylobacterium spp. strains were shown to grow in drinking water, have high cell-surface hydrophobicity, adhere to pipe surface materials, form biofilms, and survive exposure to high (60° C) temperatures. It can be concluded that Methylobacterium spp. strains share traits in common with other opportunistic premise plumbing pathogens (OPPPs). View Full-Text
