Presence of several pathogenic bacteria in the Metauro and Foglia Rivers (Pesaro-Urbino, Italy)

Abstract The presence of bacteria of the genera Salmonella, Campylobacter , Aeromonas and Yersinia in the Metauro and Foglia Rivers and the possible relationships with faecal indicators were studied. Monthly sampling was carried out and a total of 168 samples was obtained. Thirty-eight (22.6%) samples were positive for Salmonella spp., 52 (30.9%) for Campylobacter spp., 39 (23.2%) for Aeromonas spp. and 8 (4.7%) for Yersinia spp. No correlation was found between the microorganisms of the different bacterial genera and the indicators of faecal contamination.
