Figure 1: Distribution of ceftriaxone MIC values in gonococcal isolates tested in the AGSP, 1 April to 30 June, 2011 to 2013 This Figure compares the distribution of ceftriaxone MIC values in gonococcal isolates tested by the AGSP, for the first and second quarters of 2011 to 2013. It can been seen that there is evidence of a shift to the right with increasing proportions of strains at the MIC values at 0.03 mg/L (from 8.9% in 2011 – 11.5% in 2013); and increased proportions with decreased susceptibility to ceftriaxone - MIC value 0.06 mg/L, from 2.7% in 2011 to 11.5% in 2013. The proportion of strains with ceftriaxone MIC value 0.125 mg/L has increased from 0.1% in 2011 to 1.4% on 2013.
