Abstract:
An automatic water bath incubator which can be constructed from easily obtainable materials is described. This incubator provides temperatures necessary for both the 35 +/- 0.5 degrees C resuscitation period and the 44.5 +/- 0.2 degrees C final incubation period as required in the AOAC method for enumerating fecal coliforms by the modified A-1 test. Statistical analysis of experimental data indicated no significant differences (P greater than 0.50) in fecal coliform counts obtained by using the automatic incubator and the AOAC incubation method.
