Popis: | The comparative survival of various fecal indicator bacteria and enteric pathogens was studied in a stable well water supply by using membrane chambers. There was more variation in the 29 coliform cultures and they died more rapidly, as a group, than the 20 enterococcus cultures that were examined. The comparative survival of the organisms tested follows: Aeromonas sp. > the shigellae ( Shigella flexneri, S. sonnei , and S. dysenteriae ) > fecal streptococci > coliforms = some salmonellae ( Salmonella enteritidis ser. paratyphi A and D, S. enteritidis ser. typhimurium) > Streptococcus equinus > Vibrio cholerae > Salmonella typhi > Streptococcus bovis > Salmonella enteritidis ser. paratyphi B. S. bovis had a more rapid die-off than did S. equinus , but both had significantly shorter half-lives than the other streptococci. The natural populations of indicator bacteria from human and elk fecal material declined similarly to the pure cultures tested, whereas the die-off of fecal streptococci exceeded the coliforms from bovine fecal material. |
