Susceptibility of clinical isolates of Campylobacter jejuni to sixteen antimicrobial agents.

The activities of 16 antimicrobial agents against 103 clinical isolates of Campylobacter jejuni were tested. All the strains were susceptible to kanamycin and gentamicin. Chloramphenicol, nalidixic acid, and clindamycin were active against most of the strains. More than one-third of the strains were resistant to the tetracyclines and 12.5% were resistant to erythromycin.
