a Ribotypes and SXT genotypes are based on BglI restriction patterns of the respective genes and their flanking chromosomal sequence.
bAll strains were positive for tcpA, tcpI, acfB, toxT, ctxA, zot, and ToxR genes as well as for the O139-specific genomic DNA in DNA probe or polymerase chain reaction assays.
cAll strains were susceptible to tetracycline, ampicillin, chloramphenicol, gentamicin, ciprofloxacin, norfloxacin, nalidixic acid, streptomycin, trimethoprim, and sulfamethoxazole.
