Objective To investigate the biological characteristics and host distribution of Yersinia enterocolitica in Dengfeng, 2013. Methods Yersinia enterocolitica were isolated by tradition culture method. These bacteria were analyzed by the systematic biochemistry, serotype, and PCR detection methods. Results There were 1 138 samples collected in 2013. The isolation rate of Y. enterocolitica was 14.85%(169/1 138), the isolation rate of swine was 36.55%(144/394). In total, 146(86.39%), were classified into biology type 3 and O:3. The toxicity gene distribution characters were as follow:81.06%(137/169) of them were ail+, ystA+, yadA+, virF+, 5.33%(9/169) were ail+, ystA+, 12.43%(21/169) were ystB+, 1.18%(2/169) were ail-, ystA-, ystB-, yadA-, virF-. Conclusion Swine were important host as pathogenic Y. enterocolitica. O:3 was the major serotype.
Key words： Yersinia enterocolitica; Toxicity gene; Biological type; Dengfeng
