Complete Genome Sequence of Brucella suis Field Strain BCB025 of Sequence Type ST22

Brucella is a genus of relatively conservative pathogenic bacteria. Brucella suis is the most diversified Brucella species. Strains of B. suis belong to different sequence types. Here, we report the genome sequence of B. suis strain BCB025, one isolate of the sequence type 22 epidemic in China. Brucellosis represents one of the most important infectiouszoonosis epidemics worldwide, leading to great economic and public health problems (6). Brucella spp. are the etiological patho-gens of brucellosis. Due to its unique characteristics of long sur-vival time in environments and easy aerosol formation, Brucella constitutes a potential bioterrorism agent that could be targeted against military personnel and civilians (2). Therefore, early de-tection and genetic polymorphism analysis are important for pathogen verification and source tracing. The genus Brucella is divided into different species according to host preferences and other related phenotypes. Of these species,B.melitensis is themost common one that causes human cases, followed by B. abortus and B. suis. Compared with B. melitensis, B. suis shows reduced viru
