Category: Microbial Identification
Identifying microorganisms can be a very difficult task. They are not all alike. There is not one system that can identify all microorganisms. Every system has its strong points and weaknesses. Sometimes additional testing is needed because one system failed to name an organism. Other times additional testing is needed to confirm that the name given is correct Nelson Laboratories has worked hard to put together different systems that will complement each other and work together to give the best IDs. These tests include the Vitek® 2 Compact identification system, Gram Stain, mold identification, MIDI Identification system, API strips and other biochemical tests.

VITEK 2 Compact Standard (5-7 days) includes Gram stain USP 71, ISO 11737
The Vitek® 2 Compact is the newest identification system from BioMerieux and is the primary identification system at Nelson Labs. The Vitek® 2 Compact is capable of identifying Gram positive, Gram negative, Bacillus, and yeast organisms.
Gram stain USP 71, ISO 11737
A gram stain is a simple test to distinguish the type of microorganism. The organism is heat fixed and differentially stained on a microscope slide to be read under a microscope.
MIDI bacteria identifications (includes Gram stain) USP 71, ISO 11737
MIDI analyzes fatty acids that are extracted from the cell walls of bacterial cultures and methylated.
Biochemical test (coagulase, oxidase, PYR test or catalase) USP 71, ISO 11737
The IDs section at Nelson Labs has several biochemical tests that can be carried out to eliminate or support results from our main test systems. These tests include the Oxidase test, Coagulase test and Catalase test.
