Identification of Clinically Significant Microorganisms

Thermo Fisher Scientific has announced that its range of biochemical identification kits is one of the widest available to clinical microbiologists today, providing reliable results in simple and convenient formats. The range, which includes the rapid and easy-to-use Remel RapID microbial identification systems and the Oxoid Microbact biochemical identification kits, requires no capital investment, so it allows even small laboratories to confirm the identification of clinically significant bacteria, yeasts and fungi. The RapID range is the fastest and most convenient identification system of its kind. With its simple, one-step inoculation procedure, it allows accurate identification of a comprehensive range of micro-organisms in just four hours. The RapID method detects pre-formed bacterial enzymes and, therefore, is not dependent on the growth of the organism. This allows the panels to be incubated aerobically without the need for oil overlays, which saves time and resources.

Each RapID kit has the same simple procedure, allowing it to be adopted easily in laboratory workflows, and the biochemical reactions are clearly visible as distinct color changes. These are interpreted quickly and conveniently by the Electronic RapID Compendium (ERIC), a user-friendly, Windows-based software package, to minimize misidentifications and to ensure accurate and reliable results. In trials, RapID kits demonstrated excellent performance in the identification of oxidase negative Enterobacteriaceae, anaerobic bacteria, Gram-negative glucose non-fermenters, Corynebacterium species, yeasts and related organisms and streptococci and related organisms. In addition, a new system for the identification of staphylococci and related organisms is now available. The Oxoid range of Manual Identification Systems also includes the Microbact biochemical identification kits for the identification of Gram-negative bacteria (the Enterobacteriaceae and miscellaneous Gram-negative bacteria) (Microbact 12A/E; 12B and 24E), Listeria species (Microbact 12L) and clinically important staphylococci (both coagulase-negative and coagulase-positive staphylococci) (Microbact 12S). These kits are available in convenient strip or microplate format, and organism identifications are based on pH changes and substrate utilization.
