Rabbit production is very important to improve the consumption of animal proteins in developing nations (Adeyinka, 2007). The occurrence of diseases is inevitable in any animal production unit and leads to prospective economic losses (Quesada et al., 2013). Pasteurellosis induced by Pasteurella multocida (P. multocida), a virulent and readily transmitted coccobacillus, is one of the rabbit's most serious bacterial diseases and leads to great financial damages in big production systems worldwide (Takashima et al., 2001). This disease is characterized by multiple clinical symptoms, like respiratory distress, genital disorders, otitis, abscesses and septicaemia, but P. multocida infection may also asymptomatic (Jaglic et al., 2008). Rabbits could become infected with P. multocida instantly after birth, and the incidence of colonization rises with age to approximately 5 months. Most adult rabbits are thought to have been infected with P. multocida (Palócz et al., 2014).
