Additional file 4: of Antimicrobial susceptibility of Streptococcus suis isolated from diseased pigs, asymptomatic pigs, and human patients in Thailand

Figure S2. Heatmap illustrates susceptibility, i.e. susceptible, intermediate, and resistant, of Streptococcus suis, isolated from diseased pigs during the two different periods of time towards testing antibiotic drugs. The isolated bacteria were clustered, based on the period of isolation, i.e. 2006–2007 (n = 23) and 2012–2015 (n = 23). Associations between the period of isolation and susceptibility of each antibiotic drug were analyzed using Pearson’s Chi-square dependent test. The asterisk indicates that null hypothesis of the Chi-square test was rejected (P-value < 0.05), suggesting a significant association. (TIF 244 kb
