The Campylobacter Agar CF/20 is a highly selective medium designed for the isolation and cultivation of Campylobacter spp., particularly Campylobacter jejuni, a pathogen known to cause gastroenteritis in humans. This medium is enriched with 5% sheep blood, which provides essential nutrients for the growth of demanding bacteria.

Composition of Campylobacter Agar

The formulation of Campylobacter Agar CF/20 includes:

• Peptone, tryptone, and enzymatically digested liver: Rich sources of amino acids and proteins, essential for bacterial growth.


• Yeast extract: Provides B vitamins, essential for microbial metabolism.


• Sodium chloride: Maintains the osmotic balance of the medium, promoting an optimal growth environment.


• Potassium phosphate: Acts as a buffering system, stabilizing the pH of the medium during incubation.


• Agar: Functions as a solidifying agent, allowing the formation of well-defined colonies.


• Sheep blood: Adds supplementary nutrients, supporting the growth of demanding bacteria.


• Antimicrobial agents: Suppress normal microbial flora in fecal samples, facilitating the isolation of C. jejuni.

Usage Procedure

To achieve optimal results, follow these steps:

1. Streak the sample to be examined on the surface of the medium, ensuring isolated colonies.


2. Incubate at 42°C for a period of 24-48 hours in a microaerophilic atmosphere.

Applications of Campylobacter Agar

This medium is particularly useful in:

• Clinical microbiology laboratories for the isolation of Campylobacter from fecal samples.


• Epidemiological studies to monitor the presence of C. jejuni in food and water.


• Scientific research to better understand the pathogenicity and antibiotic resistance of Campylobacter spp.

Benefits of Campylobacter Agar CF/20

By using Campylobacter Agar CF/20, laboratories can:

• Effectively isolate Campylobacter jejuni and other Campylobacter spp. from contaminated samples.


• Reduce the time required for microbiological analysis due to its selective formulation.


• Obtain reliable and reproducible results, contributing to faster and more accurate diagnoses.

Choose the Campylobacter Agar CF/20 for effective and safe isolation of Campylobacter spp. and to ensure the quality of your microbiological tests.
