In the current study, 14 Brucella suis biovar 2 (B. suis bv 2) strains isolated from slaughter pigs in Cairo were sequenced using Illumina technology to investigate genetic diversity, antimicrobial resistance (AMR) genes, and virulence-associated determinants. These strains were the first B. suis bv 2 isolates from Egypt. To place them in a global context, 92 genomes of B. suis were retrieved from the NCBI database and used for comparison. The in-silico analysis of MLST showed that all isolates have ST16. No resistome but 43 virulomes have been found without differences in distribution. The cgMLST classified the Egyptian B. suis strains into a complex type (CT) encompassing four distinct cgMLST sequence types. The closest relatives were strain B. suis 94/11 of an unknown origin and a Danish strain. Whole-genome sequencing analysis proved low diversity of Egyptian B. suis isolates; thus, a single introduction event is assumed. Investigation of a large number of B. suis isolates from different governorates is required to tailor control measures to avoid further spread.
