a
MIC90, MIC required to inhibit the growth of 90% of the strains tested.
b
Data for CRO and AZM are based on 268 pathogens. Sixteen isolates (non-cholera-causing vibrios, P. shigelloides, and Aeromonas spp.) from India were not included in this part of the study.
c
Others include non-cholera-causing vibrios, P. shigelloides, and Aeromonas sp. isolates.
