Resistance of Salmonella and Campylobacte
“Antimicrobial resistance is one of the greatest threats we face worldwide, affecting humans, animals, and the environment. Working together remains key to tackling this complex problem. In our work, we embody the One Health approach, recognising the close links and interdependency of the health of humans, animals, plants, and the wider environment,” said ECDC and EFSA chief scientists Mike Catchpole and Carlos Das Neves in a joint statement.
There were encouraging trends in several countries, where an increasing proportion of bacteria from food-producing animals was susceptible to all tested antimicrobials. Moreover, the prevalence of Extended-spectrum Beta-lactamases (ESBLs) and AmpC beta-lactamases (AmpC) producing E. Coli is decreasing.
A decline in the resistance of Salmonella to ampicillin and tetracycline was also observed in humans in several countries over the period 2013–2021. This was particularly evident in S. Typhimurium, a type of Salmonella commonly associated with pigs and calves, which is often multidrug-resistant. Data also show decreasing trends in resistance of Campylobacter jejuni to erythromycin in humans and broilers.
This type of antimicrobial is very important in the treatment of campylobacteriosis.
However, the report also shows an increasing trend over the same period in the resistance of S. Enteritidis and C. jejuni to ciprofloxacin in humans. S. Enteritidis and C. jejuni cause most cases of salmonellosis and campylobacteriosis infections in humans.
Similar trends were observed in C. jejuni from broilers between 2009 and 2020, where resistance to ciprofloxacin increased in several countries. The level of ciprofloxacin resistance in Campylobacter is now so high that this antimicrobial can no longer be recommended in the treatment of severe Campylobacter
