Abstract:
:We describe a multiplex PCR assay to identify and discriminate between isolates of Campylobacter coli, Campylobacter jejuni, Campylobacter lari, and Campylobacter upsaliensis. The C. jejuni isolate F38011 lpxA gene, encoding a UDP-N-acetylglucosamine acyltransferase, was identified by sequence analysis of an expression plasmid that restored wild-type lipopolysaccharide levels in Escherichia coli strain SM105 [lpxA(Ts)]. With oligonucleotide primers developed to the C. jejuni lpxA gene, nearly full-length lpxA amplicons were amplified from an additional 11 isolates of C. jejuni, 20 isolates of C. coli, 16 isolates of C. lari, and five isolates of C. upsaliensis. The nucleotide sequence of each amplicon was determined, and sequence alignment revealed a high level of species discrimination. Oligonucleotide primers were constructed to exploit species differences, and a multiplex PCR assay was developed to positively identify isolates of C. coli, C. jejuni, C. lari, and C. upsaliensis. We characterized an additional set of 41 thermotolerant isolates by partial nucleotide sequence analysis to further demonstrate the uniqueness of each species-specific region. The multiplex PCR assay was validated with 105 genetically defined isolates of C. coli, C. jejuni, C. lari, and C. upsaliensis, 34 strains representing 12 additional Campylobacter species, and 24 strains representing 19 non-Campylobacter species. Application of the multiplex PCR method to whole-cell lysates obtained from 108 clinical and environmental thermotolerant Campylobacter isolates resulted in 100% correlation with biochemical typing methods.
