Abstract:
Titertek-Enterobac-Ras (TTE-RAS), a new semi-automated system for the identification of the Enterobacteriaceae-within five hours, has been evaluated and compared with conventional methods. This note presents the results upon 655 strains, mainly Enterobacteriaceae TTE-RAS provided correct identification for about 92 p. cent and 97 p. cent of Enterobacteriaceae respectively before and after carrying out supplementary tests according to manufacturer's instruction. TTE-RAS gave 97 p. cent specific results for Salmonella. On the other hand, the system correctly identified Aeromonas hydrophila, but not the Gram negative strict aerobic bacteria.
