Abstract
- A lytic bacteriophage PHB01 specific for Pasteurella multocida type D was isolated from the sewage water collected from a pig farm. This phage had the typical morphology of the family Podoviridae, order Caudovirales, presenting an isometric polyhedral head and a short noncontractile tail. PHB01 was able to infect most of the non-toxigenic P. multocida type D strains tested, but not toxigenic type D strains and those belonging to other capsular types. Phage PHB01, the first lytic phage specific for P. multocida type D sequenced thus far, presents a 37,287-bp double-stranded DNA genome with a 223-bp terminal redundancy. The PHB01 genome showed the highest homology with that of PHB02, a lytic phage specific for P. multocida type A. Phylogenetic analysis showed that PHB01 and PHB02 were composed of a genus that was close to the T7-virus genus. In vivo tests using mouse models showed that the administration of PHB01 was safe to the mice and had a good effect on treating the mice infected with different P. multocida type D strains including virulent strain HN05. These findings suggest that PHB01 has a potential use in therapy against infections caused by P. multocida type D. [ABSTRACT FROM AUTHOR]
