A suitable medium for the transport of Pasteurella multocida in nasal
specimens from rabbits was investigated by using pure cultures of the
organism and nasal swabs from infected rabbits. First, the ability of eight
transport media to preserve the viabilities of P. multocida strains
isolated from rabbits was studied. Cary-Blair medium and Leibovitz medium
no. 15 (L-15) were found to be superior to the other six media tested,
enabling survival of the organism for more than 14 days at room
temperature. Second, the survival of P. multocida in nasal specimens was
evaluated on both Cary-Blair medium and L-15. The recovery rate of the
organism from these two media was more than 80 to 90% during 4 days of
storage and decreased gradually with increasing preservation time. There
were no significant differences (P > 0.05) in recovery rates of the
organism between Cary-Blair medium and L-15. On the basis of these results,
we recommend the use of Cary-Blair medium for the transport of P. multocida
in rabbit nasal specimens because of the ease of transport of nasal swabs
by mail.
