An evaluation of the Replireader in the identification of Enterobacteriaceae isolated from urine and in the recording of sensitivity tests performed by an agar dilution method.

In the Replireader system for identifying Enterobacteriaceae, plates of biochemical media are inoculated with a replicator and the results are put into a computer. The machine correctly identified 92x2% of 734 strains of Gram-negative bacilli isolated from urine; it was incorrect in 0x8% and failed to recognise 7%. The Replireader was also used to record the results of sensitivity tests using a plate dilution method in which the drugs were provided by impregnated filter papers (Adapads).
