<i>Aeromonas</i> Species from Nonchlorinated Distribution Systems and Their Competitive Planktonic Growth in Drinking Water

Abstract

The occurrence of the bacterial genus Aeromonas in nonchlorinated drinking water in the Netherlands is regarded as an indication of elevated microbial regrowth in the distribution system. Identification of the prevalent species in 10 distribution systems by genotyping yielded seven different species, with A. rivuli , A. veronii , and A. sobria being the most dominant ones.
