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 pathogene complex of bovine respiratory diseases. During infection, these species cause complications which can lead to sepsis and death of the animal. CHROMagar™ 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. CHROMagar™ Pasteurella medium can also be used for samples from the respiratory tract of mammals such as cats and dogs. 1. Unique chromogenic media : First and only available specific medium for Pasteurellaceae in the market 4. Early plate reading : Most isolates will have a noticeable colony size after just overnight incubation. 2. Lower workload contrary to general media like blood agar, CHROMagar™ Pasteurella differentiate the target group from the other bacteria by a distinctive mauve colony color. 3. Highly selective : Most of the environmental flora will be inhibited.
