| phylogenetic analysis of urease-positive thermophilic campylobacter (uptc) strains based on the molecular characterization of the flaa gene. | molecular cloning, nucleotide sequencing, and characterization of the flaa gene from additional isolates of urease-positive thermophilic campylobacter (uptc) were performed. these isolates were obtained from the natural environment in northern ireland (n = 9 from mussels) and in england (n = 1 from sea water). all isolates carried the shorter flaa gene, [open reading frames (orfs), 1,461 to 1,503 base pairs], without any internal termination codons, and did not carry any flaa pseudogenes. the up ... | 2011 | 21874596 |
