Whole genome characterization of a multidrug-resistant hypervirulent Pasteurella multocida with a new drug-resistant plasmid.

ABSTRACT: Pasteurella multocida (P. multocida) is a zoonotic bacterium that can cause diseases in a variety of animals. It was divided into 5 serogroups, and serogroup A is mainly prevalent in avian hosts. We isolated a virulent and multidrug-resistant P. multocida strain from Guangdong duck liver and named it PMWSG-4 (GenBank accession no. CP077723.1). To understand the pathogenicity of this strain, the pathogenicity test was carried out with mice and ducks. The results showed that PMSWG-4 was highly pathogenic to ducks and mice, and the LD50 is 4.5 and 73 CFU, respectively. In order to study its genetic characteristics, pathogenicity, and relationship with the host, we performed a whole genome sequencing. The genome size of the isolated PMWSG-4 was 2.38 Mbp, with a G+C content of 40.3%, and coding
