Multidrug-resistant Streptococcus pneumoniae serogroup 19, including serotypes 19A and 19F, associated with clonal complex 320/271 (CC320/271), has been previously shown to be predominant in many countries after introduction of a 7-valent pneumococcal conjugate vaccine (PCV7). However, in Japan there has been no epidemiological research focused on penicillin-nonsusceptible isolates after this event. Therefore, we aimed to characterize penicillin-nonsusceptible S. pneumoniae (PNSSP; penicillin… CONTINUE READING
