摘要:
The characterization of Campylobacter jejuni has been significantly improved by the use of multilocus sequence typing (MLST), which allows the relationship between isolates to be determined. The sequence types (STs) of 261 isolates of C. jejuni from New Zealand were determined. Isolates were obtained from a range of sources including chicken meat, cattle, pigs, duck, sheep, water and human infections. Thirty-two new alleles and 44 new STs were identified. Comparison of the MLST data and pulsed-field gel electrophoresis macrorestriction profiles showed that the macrorestriction profiles were good predictors of the clonal complex (CC) but not ST. All the major CCs identified elsewhere in the world were found in New Zealand as well as the association of certain CCs with particular animal niches. The majority of new STs identified were from river water isolates.
