[Multilocus sequence typing analysis of 47 Campylobacter jejuni strains isolated from poultry in Hubei province].
OBJECTIVE
To study the epidemiological and molecular characteristics of Campylobacter jejuni in poultry in Hubei province, we used multilocus sequence typing method to classify 47 local C. jejuni strains.


METHODS
Genomic DNA of each isolated strain was extract, seven housekeeping genes including aspA, g1nA, g1tA, glyA, pgm, tkt and uncA were amplified by PCR and sequenced, and then the sequences of genes were analyzed using MLST database.


RESULTS
There were a total of 38 sequence types and 10 clonal complexes, and ST353 and ST464 complexes were the largest amount of the population of C. jejuni analyzed, of which 2 new allelic profile and 25 new sequence types were found. Phylogenetic tree shows that sequence types from different types of poultry and different regions were different.


CONCLUSIONS
Forty-seven C. jejuni strains isolated from poultry in Hubei were analyzed using MLST and showed abundant genetic diversity, it will provide scientific data to the epidemiological investigation of C. jejuni in Hubei, China.
