Prevalence of Yersinia enterocolitica Bioserotype 3/O:3 among Children with Diarrhea, China, 2010-2015.

Yersinia enterocolitica is thought to not significantly contribute to diarrheal disease in China, but evidence substantiating this claim is limited. We determined the prevalence of Y. enterocolitica infection and strain types present among children <5 years of age with diarrhea in China.

Development of double loop-mediated isothermal amplification to detect Listeria monocytogenes in food.

In this study, a double loop-mediated isothermal amplification (dLAMP) based on two target genes hlyA and iap was developed for the rapid detection of Listeria monocytogenes in food. The results revealed that the detection time and temperature of our dLAMP assay for L. monocytogenes were 15 min and 63 °C respectively, with a sensitivity of 10 fg DNA of L.

[Analysis of the variation and changes of Yersinia enterocolitica in Ningxia area from 1984 to 2011].

Objective: To analyze the genetic evolution and bacterial type changes of Yersinia enterocolitica in the Ningxia area between year 1984 and 2011.

Methods: A total of 296 strains of Yersinia enterocolitica was collected from diarrhea patients, pig, rodents, sheep and dogs between year 1984 and 2011. The serotype, biotype, ail, ystA, ystB, yadA, virF and other toxic genes were detected.

[Characteristics of Yersinia enterocolitica genes isolated in Ningxia Hui autonomous region from 1997 to 2010].

Objective: To investigate the distribution of virulent genes of Yersinia enterocolitica (Y. enterocolitica) in Ningxia Hui autonomous region and the characteristics of the molecular patterns of Y. enterocolitica.
