The aim of this study was to evaluate the effectiveness of Cary-Blair, Amies and modified Cary-Blair medium for transport of Pasteurella multocida and Mannheimia haemolytica strains. Pure cultures of nine strains of P. multocida, representing all subspecies, and nine strains of M. haemolytica were inoculated into different media to test their convenience. The ability of the strains to survive in each of these media was determined periodically (on days 5, 10, 15, 20, 30, 45, 60, 75, 90, respectively) at different temperatures (alternatively at 21 deg C and 4 deg C) and at room temperature (constantly at 21 deg C). P. multocida strains survived for 45 days and M. haemolytica strains for 30 days in modified Cary-Blair medium. Based on the present observation, Cary-Blair medium modified by the addition of horse blood serum is the most effective of the tested media for the transport of P. multocida and M. haemolytica strains.
