SPECIFIC DETECTION OF CAMPYLOBACTER-CONCISUS BY PCR AMPLIFICATION OF 23S RDNA AREAS

The phenotypic detection of Campylobacter concisus, a species of considerable genomic and phenotypic heterogeneity, has proven to be rather tedious in the past. Although alternative methods like DNA:DNA hybridization, immunotyping or whole-cell protein electrophoresis are valuable for the specific detection of C. concisus, they are too laborious to be performed in routine settings. Hence a simple Campylobacter concisus-specific PCR assay was developed, based on a target sequence which comprises the most variable areas of 23S rDNA. The PCR assay was successfully evaluated on a broad selection of C. concisus strains and phylogenetically related bacteria. (C) 1995 Academic Press Limited
