In 2009, a Brucella suis biovar 3 case was first reported in Hainan province. To compare the epidemiological relationship between strains of B. suis biovar 3 recently isolated from China and exogenous strains, a multiple-locus variable-number tandem-repeat analysis (MLVA) was used. The 26 strains clustered together with B. suis biovar 3 reference strain REF686, sharing all panel 1 (genotype 4: 2-3-4-11-3-1-5-2)...
To enhance the understanding of epidemiological impact of environmental Vibrio cholerae O139 strains, we characterized 10 clinical and 20 environmental isolates collected from human clinical samples and Pear River estuary during 2006 to 2008. Isolates were tested by PCR for eight virulence genes: cholera toxin (ctxA), zonula occludens toxin (zot), accessory cholera enterotoxin (ace), hemolysin (hlyA...
