Coli, Salmonella, Shigella andYersinia species. Isolation rates were:Campylobacter jejuni andC. Coli, 5.3%,Salmonella spp., 14.8%,Shigella spp., 4.6% andYersinia enterocolitica, 1.1%. Age group distribution analysis shows a higherCampylobacter isolation rate in children under one year of age. Seasonal distribution revealed a peak incidence in winter as in other Meditteranean countries. Predominant biotypes wereC. jejuni I (51%),C. jejuni II (21.5%) andC. coli I (18.8%). Antimicrobial susceptibility testing did not reveal resistance to erythromycin. Thirty of the strains harboured plasmids with 7 different profiles.engCampylobacterPortugalEpidemiologyBiotypingPlasmidsAntimicrobial resistancejournal article
