Of this group resistance to ciprofloxacin and nalidixic acid was identified in isolates from patients who had travelled to the Indian subcontinent. This study provides a Canadian perspective to a growing body of literature linking ciprofloxacin and nalidixic acid resistance to travel to the Indian subcontinent. Shigella is a common cause of diarrheal illness in North America with a rate of per 100 000 in Canada 1 and a rate of per 100 000 in the United States 2 3 . Imported cases of Shigella infections have been reported in developed countries following travel to a foreign or developing country 4 5 and may be impacted by factors including socio-economic factors 6 food distribution networks 5 and microbiologic factors 7 . Across multiple geographic regions high rates of antimicrobial resistance to multiple agents . sulfonamides tetracycline chloramphenicol ampicillin and trimethoprim-sulfamethoxazole have limited the choices for empiric antimicrobial therapy required to manage Shigella infections and reduce fecal excretion of the bacteria 8-10 with descriptions of shifting species dominance and changes in antimicrobial susceptibility 10 11 . Generally Shigella flexneri and Shigella sonnei are the dominant species and are heavily impacted by changes in antimicrobial susceptibility 12 13 . This study identifies the global regions associated with travel-related cases of .
