Figure 2. Proportion ceftriaxone-nonsusceptible isolates among all Streptococcus pneumoniae isolates acquired from patients with invasive pneumococcal disease, by 2-year period, Israel, July 1, 2009–June 30, 2015. Ceftriaxone-nonsusceptible isolates were those that could grow at a concentration above ceftriaxone’s MIC (>1 µg/mL). *In 2009–2011, the 1 ceftriaxone-nonsusceptible isolate was serotype 14. †In 2011–2013, the 5 ceftriaxone-nonsusceptible isolates included 2 of serotype 19F and 1 each of serotypes 19A, 34, and 23B. ‡In 2013–2015, the ceftriaxone-nonsusceptible isolates were serotypes 23F (n = 2) and 19A (n = 3), and 1 was not typeable.
