Figure 3: Genome size differences in isolates of different clinical phenotype.
From: Genomic signatures of human and animal disease in the zoonotic pathogen Streptococcus suis

The number of genes in 153 S. suis isolates isolated from pigs in the United Kingdom. Isolates were classified as non-clinical (isolated from the nasal passage) n=62, systemic (disease-causing and isolated from the brain, blood or joints) n=52 or respiratory (disease-causing and isolated from the lungs) n=39. Boxes show the medians and upper and lower quartiles; whiskers show the most extreme values within 1.5 times the interquartile range.
