Genetic polymorphisms identify in species/biovars of Brucella isolated in China between 1953 and 2013 by MLST.

ABSTRACT:

Background

Brucellosis incidence in China is divided into three stages: high incidence (1950s-1960s), decline (1970s-1980s), and re-emergence (1990s-2010s). At the re-emergence stage, Brucellosis incidence grew exponentially and spread to all 32 provinces. We describe the magnitude and the etiological distribution changes in mainland China by genotyping data and emphasize its recent reemergence. We also provide the genetic diversity and molecular epidemiological characteristics of Brucella.

Results

From a total of 206 Brucella isolates, 19 MLST genotypes (STs) were identified and 13 new STs(ST71-83)were found. MLST grouped the population into three clusters. B. melitensis, B. abortus and B. suis were grouped into cluster 1, 2 and 3 respectively. The predominant genotype in t
