title: Rapid recovery of Escherichia coli from estuarine water.
abstract: The efficiencies of two 24-hr elevated-temperature tests to recover Escherichia coli from estaurine water were compared simultaneously with the 72-hr standard methods procedure of the American Public Health Association (APHA). From 1,710 tubes, E. coli was recovered 222 times in lauryl tryptose medium incubated at 44 +/- 0.2 C for 24 hr, 261 times in an experimental medium incubated at 44.5 +/- 0.2 C for 24 hr, and 257 times by the 72-hr APHA method. The number of false positives enumerated was similar in all three tests. The data indicated that E. coli in raw seawater could be determined in 24 hr without a significant loss of accuracy.
