Selective media for Pasteurella multocida and Bordetella bronchiseptica.

Easily prepared and inexpensive culture medium for the isolation of Pasteurella multocida and Bordetella bronchiseptica from the nares of laboratory rabbits was prepared by incorporating 2 micrograms/ml clindamycin into standard blood agar. Using this medium, the time and materials required to identify and isolate Pasteurella multocida was substantially reduced with only a slight loss in sensitivity. The combination of 2 micrograms/ml clindamycin and 4 micrograms/ml neomycin was effective in isolating Bordetella bronchiseptica from rabbits.
