A simple and rapid method for making direct faecal coliform counts in sea water.

: A simple and rapid test for the fecal coliform analysis in seawaters by means of the direct seeding on selective-differential m-FC agar medium is described. The data set fourth show a good yield for the test insofar as test sensitivity, specificity and reliability are concerned. Consequently, its use is proposed along with, or at variance with, the traditional techniques MPN and FM which are not always of practical and easy carrying out, under particular operative conditions (need to customarily analyse a high number of samples).
