Tokyo Metropolitan Institute of Public Health
Tokyo Metropolitan Institute of Public Health has conducted trend surveillance concerning the proportion of antimicrobial-resistant Campylobacter spp. Among the 132 outbreaks of food-borne illness that occurred in Tokyo in 2017, 45 outbreaks (34.1%) were caused by Campylobacter spp., being the largest cause of bacterial food-borne illness. The proportion of fluoroquinolone-resistant Campylobacter coli (C. coli) strains was 35.7%, which was lower than the previous year. Note that, however, the number of tested strains was smaller for C.coli and this should be taken into consideration upon interpretation of the result.
