Differential System for the identification of the Enterobacteriaceae

In recent years a number of commercial systems for the identification of the Enterobacteriaceae have appeared on the market. Two of these, the API system and the Enterotube, have been available in the UK for some years and have been widely reviewed (Morton and Monaco, 1971; Smith et al., 1972; Washington, 1972; Leers and Arthurs, 1973; Brooks et al., 1974; Nord et al., 1974; Smith, 1975, Hayek and Willis, 1976). We have recently tested the R/B system, which has been available in various forms in the USA for some time and may be marketed in the UK.
