Abstract
Background Pasteurella multocida is the main cause of several infections of farm animals, and the immunity gained from commercial vaccines is for the short term only and needs to be routinely administered, so work on new vaccines against virulent P. multocida is crucial. Results In this study, the OmpH gene was amplified from ten P. multocida strains, and the PCR products were sequenced and analyzed. The results of RFLP analysis of OmpH gene digested by MspI enzyme showed that all of ten strains examined possessed one restriction site and two fragments, 350 and 650 bp. The OmpH sequence of strain No. 10 was cloned into bacterial expression vector pUCP24, and the recombinant pUCP24-OmpH was expressed in E. coli DH5α. Serum samples obtained from the ELISA test from a group of vaccinated rats indicate that the antibodies were present at high titer in immunized rats and can be tested as a vaccine candidate with a challenge. Conclusions In rats infected with the DNA vaccine and inactivated vaccine, a significant increase in serum antibody levels was observed. In addition, the DNA vaccine provided the vaccinated rats with partial protection; however, the protective efficacy was greater than that offered by the live attenuated vaccine. This successful recombinant vaccine is immunogenic and may potentially be used as a vaccine in the future.

Abstract
Pasteurella multocida (P. multocida) is the highly contagious causative agent of a broad range of diseases in animals as well as an occasional human pathogen. Economically significant infections caused by P. multocida include avian fowl cholera, rabbit snuffles, and hemorrhagic septicemia in cattle, goats and pigs. Chemotherapy of pasteurellosis infections has some limitations, such as high cost of treatment, low efficacy, and the possibility of therapy failure due to antibiotic resistance. Prophylactic immunization offers a safe and effective preventive measure in case of zoonotic diseases. Bacterins, live attenuated and some old traditional vaccines against pasteurellosis remain in use today, beside their limitations. However, the past few years have seen significant progress in research to identify modern, effective vaccine candidates, but there is no new vaccine produced by new strategies. While scientists should struggle with a lot of aspects to design vaccine producing strategies, this review shows how pasteurellosis vaccine evolved and the limitations in its application which need to be overcome.
