We analyzed 344 Shigella sp. strains, isolated between 2004 and 2014 in Switzerland for antimicrobial resistance profiles. Overall, 78.5% of the isolates showed multiple drug resistance (MDR), 10.5% were ciprofloxacin resistant and 2% harbored mph(A), a plasmid-mediated gene that confers reduced susceptibility to azithromycin, a last-resort antimicrobial agent for the treatment of MDR shigellosis.
