Descrição: dc.descriptionAbstract: Positive samples for Aeromonas spp were 127% from mineral water, 83% from artesian water and 65% from tap water The recovery of Aeromonas spp was significantly higher in bottled mineral and artesian water than in tap water from municipal supplies The occurrence of the Aeromonas spp did not correlate significantly with traditionally used contamination indicator bacteria (ie total coliforms) in artesian water samples However, a significant correlation was found between Aeromonas spp and total coliforms in both mineral water and tap water samples The presence or absence of a correlation between indicator bacteria and Aeromonas could reflect the occasional appearance of pathogens in drinking water and the different rates of survival and recovery of these agents compared with those fecal indicators The finding that 416%, 148% and 9% of the artesian water, bottled water and tap water, respectively, sampled in the current study failed to meet the Brazilian standard for total coliforms in drinking water should therefore be of concern This highlights the need for an improved surveillance system for both the bottled water industry and the municipal water supplies Strains belonging to the genera Aeromonas identified to the species level were A hydrophila and A jandaei The public health significance of the large number of Aeromonas spp that can develop in water is unclear There is an urgent need to compare the effects of a greater number of strains belonging to each of these species in a wider range of animal models of infection These results can contribute to the re-evaluation of the criteria used to analyse the microbial quality of drinking water and to define measures for limiting Aeromonas densities in drinking water-
