I have two questions that require some advice:
1. Are these these bacteria the same or are they completely different?
Under the new WHO guidelines for recreational water quality it says that
these two are interchangeable, so I'm a bit confused as I thought they were
different. So, if a guideline refers to enterococci does it imply FStrep as
2. I'm looking at the APHA Standard methods and there are two different
methods for testing for FStrep and Enterococci. However, in the
verification stage it says that colonies can be tested for growth on NaCl to
test for Enterococci. Does this mean that i can test for Enterococci
following the FStrep procedure and base my Enterococci counts on this?
Thank you for your assistance.
