Short Communication: Antimicrobial Susceptibility of Campylobacter jejuni subsp. jejuni Assessed by E-test and Double Dilution Agar Method in Southern Chile

The susceptibility patterns of 108 Campylobacter jejuni subsp. jejuni clinical strains, to six antimicrobial agents was determined by using the E-test and the double dilution agar methods. Using both methods, no strain was found to be resistant to ciprofloxacin, erythromycin and gentamicin, but two (1.8%) were resistant to tetracycline and all to aztreonam. Seven (6.5%) strains were resistant to ampicillin by the E-test and five (4.6%) by the double dilution agar methodand by both methods. No great discrepancies were observed between both methods.
