PCR FOR THE DETECTION AND TYPING OF CAMPYLOBACTERS

The flaA gene of Campylobacter sp. was amplified using PCR. Primers were chosen which amplified 1.3 kb of the flaA gene in Camp. jejuni and Camp. coli. 'Campylobacter upsaliensis' amplimer was approximately 1.7 kb in size and was easily distinguishable. Other species of campylobacter failed to yield amplimer. The amplimer was digested with Alu 1 which demonstrated considerable restriction fragment length polymorphism and should allow the development of a rapid novel typing scheme which does not rely on previous culture of campylobacter strains.
