1. Unique Chromogenic media: First and only available specific medium for Pasteurellaceae in the market.

2. Lower workload:Contrary to general media like blood agar, CHROMagarTM Pasteurella differentiates the target group from the other bacteria by a distinctive mauve colony color.

3. Highly Selective: Most of the environmental flora will be inhibited. 

4. Early plate reading: Most isolates will have a noticeable colony size after just overnight incubation.


Medium Description

Gain flexibility using powder rather than ready to use plates: Use the entire pack, or if there is a need for a smaller number of plates, just a portion. If kept under appropriate storage temperature, CHROMagarTM Pasteurella has a more than 18 months shelf life. This flexibility is essential to avoid the waste resulting from expired-unused plates.


Focus on Pasteurellaceae


In the veterinary field, respiratory infections in cattle herds can cause stunted growth, decline in milk production and death of animals, leading to significant economic losses.

Bacteria of the Pasteurellaceae family are commensal to the upper respiratory tract of many vertebrate species. Among them, Histophilus somni, Pasteurella multocida and Mannheimia haemolytica are among the main bacteria associated with the pathogen complex of bovine respiratory diseases. During infection, these species cause complications which can lead to sepsis and death of the animal. 

CHROMagarTM Pasteurella was therefore developed to improve the detection of Pasteurellaceae from a bovine respiratory sample (eg. nasal swab, trans-tracheal aspiration (TTA) and lung). This chromogenic medium to aid in qualitative diagnosis allows the detection and isolation of Pasteurellaceae colonies by inhibition or differentiation of the annex flora.

CHROMagarTM Pasteurella medium can also be used for samples from the respiratory tract of mammals such as cats and dogs.
