Description:
<p>Results of an intensive study on the occurrence and strain distribution for 12,536 fecal streptococcus strains found in warm-blooded animal feces and numerous water sources from a wide geographical area reveal several new factors that must be understood for a proper interpretation of the sanitary significance of this bacterial group in water pollution studies. The ubiquity of Streptococcus faecalis var. liquifaciens in the water environment and the occasional occurrence of an atypical S. faecalis associated with vegetation shows the need for including the fecal coliform examination in recreational water quality measurements. Applications of the fecal streptococcus indicator system in stream pollution are the development of fecal coliform to fecal streptococcus ratios that will further define possible sources of the fecal discharge into the stream; and the detection of the S. bovis and S. equinus subgroup which was not found in human feces and may be considered a specific indicator of non-human animal pollution.</p>
