Analysis on etiological characteristics of Brucella strains isolated in Shanxi, 1950–2018

    Graphical Abstract
    • Abstract
  • ObjectiveTo understand the etiological characteristics of brucellosis in Shanxi province from 1950 to 2018 and provide evidence for the further analysis on the epidemiological characteristics of brucellosis.
    MethodsThe analysis was conducted on the information of the Brucella strains isolated in different areas and from different host samples in Shanxi province during 1950–1981, 1982–1991 and 1992–2018.
    ResultsFrom 1950 to 2018, a total of 417 Brucella strains, i.e. 331 B. melitensis strains, 1 B. abortus strain, 1 B. suis strain, 1 atypical Brucella strain and 83 unspecific Brucella strains, were isolated from different samples of 5 hosts in Shanxi.
    ConclusionShanxi province is a mixed spread area of B. melitensis, B. abortus and B. suis. From 1950 to 1981 and from 1982 to 1991, the predominant species of Brucella were B. melitensis 1 and B. melitensis 2, and the predominant species of Brucella was B. melitensis 3 during 1992–2018. It was found that some strains of B. melitensis were isolated from deer rather than sheep and goats, suggesting the possible host shifting of B. melitensis.
