It has been demonstrated that microbial populations in waters for human consumption may be injured by natural factors, as well as by disinfectants, such as chlorine. Injured microorganisms aren't able to have a normal growth on selective media commonly employed for analytical determinations. This could lead to false negative responses concerning the hygienic quality of water. Furthermore, bacterial strains referable to pathogenic species, such as Salmonella typhimurium, Shigella sonnei and Yersinia enterocolitica, are normally more resistant to injuring factors than microbial indicators of faecal pollution (eg faecal coliforms and faecal streptococci). For this reason, it is necessary to develop new and suitable analytical methods, able to detect injured microorganisms too.
