Abstract
We aimed to clarify if the thermophilic Campylobacter lari organisms including urease-negative (UN) C. lari and urease-positive thermophilic Campylobacter (UPTC) can be differentiated at the species and/or subspecies levels by employing the full-length flaA gene and flaA short variable region (SVR) nucleotide sequence information or not. Thermophilic Campylobacter isolates (n = 45) including UN C. lari (n = 17), UPTC (n = 18), and Campylobacter jejuni (n = 10) were well discriminated at the isolate level by the unweighted pair group method using arithmetic means analysis and neighbor joining procedures constructed based on the full-length flaA gene and flaA SVR nucleotide sequence information. Thus, these procedures may possibly be useful for epidemimological studies for C. lari and C. jejuni.
