Antimicrobials used to treat zoonotic diseases such as campylobacteriosis and salmonellosis are becoming less effective, new data from the European Centre for Disease Prevention and Control (ECDC) and European Food Safety Authority (EFSA) confirms.
The joint report presents 2017 data from 28 EU Member States on humans, pigs, and calves aged under one year, which continues the rising trend in antibiotic resistance identified in previous years.
In Salmonella from humans, and in Salmonella and E.coli isolates from fattening pigs and calves, high proportions of isolates were resistant to ampicillin, sulfonamides, and tetracyclines, whereas resistance to third-generation cephalosporins was uncommon.
In Campylobacter from humans, high to extremely high proportions of isolates were resistant to ciprofloxacin and tetracyclines, particularly in Campylobacter coli (C.coli). In five countries, high to very high proportions of C. coli from humans were resistant also to erythromycin, leaving few options for treatment of severe Campylobacter infections.
Combined resistance to critically important antimicrobials in both human and animal isolates was generally uncommon but very high to extremely high multidrug resistance levels were observed in S.Typhimurium and its monophasic variant in both humans and animals. S.Kentucky from humans exhibited high-level resistance to ciprofloxacin and a high prevalence of extended-spectrum beta-lactamas (ESBL).
