Pasteurella multocida is the causative agent of pasteurellosis, a major disease in most domestic animals and livestock. In this study, a total of 34 isolates of P. multocida from rabbits and other domestic animals from Mexico with respiratory diseases underwent polymerase chain reaction-based capsular typing. One sheep isolate was found to belong to capsular serogroup D, whereas the rest of the rabbit, sheep, cattle, pig, goat, and duck isolates belonged to capsular serogroup A of P. multocida. This is the first report of capsular type A in P. multocida isolates from rabbits and duck origin in Mexico.
