Background: Yersinia enterocolitica is a human-animal-fish-associated infectious diarrhea pathogen that has caused widespread international attention in recent years. Many strains of Yersinia enterocolitica were identified from different animal species, but there is no information reported Yersinia enterocolitica in Gymnocypris przewalskii . The Gymnocypris przewalskii is a very important species in the Qinghai Lake. They were listed in the China' s second-class protected animal species. Preliminary research on the distribution of Yersinia enterocolitica and the drug sensitive fauna test on Gymnocypris przewalskii was a urgent solving problem for which maintain the original ecological symbiotic system and restore Gymnocypris przewalskii resource. In order to solve these issues, we performed this research.
Results: The results showed that 5 strains Yersinia enterocolitica were obtained, positive ratio was 6.67% (5/75). The average drug-resistant of 5 strain Yersinia enterocolitica was 54.29% (38/70) to 14 kinds of antibiotic. The result of 16S rRNA gene of Yersinia enterocolitica identified showed that one piece of 1419 bp specific braid was obtained. The homologies of nucleotide of 16S rRNA were 91%-95% between 15 strains of Yersinia enterocolitica from GenBank by measuring sequence.
Conclusion: Yersinia enterocolitica can infect Gymnocypris przewalskii . Some strains have drug-resistant effect. The 16S rRNA gene matches 91%-95% with other strains nucleotides download from GenBank and forms a unique branch separated from them.
