WebSeven (0.68%) out of 1032 S. pneumoniae isolates collected by the North Fukuoka Infectious Diseases Working Group were found to be Optr S. pneumoniae. Resistant strains had MICs of optochin 2- to 64- fold higher than susceptible strains, possessed different antimicrobial resistance profiles, and belonged to different serotypes.
