Characteristics of Yersinia enterocolitica in Ningxia,China,2008-2013
摘要
Abstract
We investigated the distribution characteristics of Yersinia enterocolitica in Ningxia ,China .In accordance with the requirements of the National Yersinia enterocolitica Disease Monitoring Scheme ,Y .enterocolitica were isolated from differ‐ent kinds of specimens collected in Ningxia in 2008 to 2013 .Then they were serotyped and detected for virulence gene and ana‐lyzed the pulsed‐field gel electrophoresis (PFGE) in Chinese CDC .It was found that 173 strains were isolated from various types of 9 643 specimens ,and the detection rate was 1 .79% .There were statistical differences among detection rates in differ‐ent years and in different specimens (P<0 .01) .Pathogenic serotypes O∶3 and O∶9 carried ail gene and ystA gene were de‐tected from specimens of pigs and diarrhea patient .Non‐pathogenic serotypes O∶5 and O∶8 and non‐typeable strains didn't carry ail gene and ystA gene ,and also can't be detected from swine ,cattle ,sheep ,chickens and dogs .In conclusion ,Y .en‐terocolitica was widely distributed in Ningxia and pigs were the dominant animal host .In all pathogenic serotypes ,the highest proportion was O∶3 following by O∶9 .It was no time and regional difference in the distribution of that in Ningxia ,China .关键词
