Liofilchem™ Enterosystem 18R Codebook

The Liofilchem™ Enterosystem 18R Code Book is a comprehensive reference tool designed to assist in the interpretation of results generated from the Liofilchem™ Enterosystem 18R diagnostic panel. This code book plays a crucial role in the accurate identification of Gram-negative, oxidase-negative Enterobacteria based on the biochemical reactions evaluated during testing.

Purpose

• Identification of Microorganisms: The code book allows users to match the unique biochemical profile generated by the Enterosystem 18R to specific bacterial species.
• Streamlined Analysis: Converts biochemical reactions into a numerical code, simplifying the identification process.
• Comprehensive Reference: Covers a wide range of Enterobacteria, ensuring robust diagnostic capabilities.

Key Features

1. Biochemical Profile Interpretation:
   • Each reaction in the 18 biochemical tests is recorded as positive or negative.
   • Positive reactions are assigned numerical values, which are summed within groups to create a profile number.
2. Microbial Identification:
   • The numerical profile is cross-referenced in the code book to determine the corresponding bacterial species.
3. Wide Scope of Identification:
   • Includes clinically significant pathogens such as:
     • Escherichia coli
     • Shigella spp.
     • Salmonella spp.
     • Klebsiella spp.
     • Proteus spp.
     • Yersinia spp.
   • Covers less common species for enhanced diagnostic reach.
4. User-Friendly Format:
   • Organized alphabetically or by numerical codes for quick lookup.
   • Designed for ease of use, even for laboratories with high workloads.
5. Compatibility:
   • Specifically designed for use with the Liofilchem™ Enterosystem 18R panel.
   • Supports both manual interpretation and automated result analysis when integrated with compatible systems.

How to Use the Code Book

1. Perform Biochemical Tests:
   • Inoculate and incubate the Enterosystem 18R panel as per the protocol.
   • Observe and record the color changes in each well after 12–24 hours of incubation.
2. Generate a Numerical Code:
   • Group the test results into categories as per the Enterosystem 18R protocol.
   • Assign a numerical value to positive reactions and calculate the profile code.
3. Identify the Organism:
   • Refer to the Enterosystem 18R Code Book to match the profile code with the corresponding bacterial species.
   • Confirm identification using supplementary tests if needed.

Benefits

Applications

1. Clinical Diagnostics:
   • Identifies Gram-negative bacteria in infections such as UTIs, sepsis, and gastroenteritis.
2. Industrial Microbiology:
   • Used in food, water, and pharmaceutical quality control.
3. Research and Education:
   • Assists in studies of bacterial metabolism and pathogenicity.
