Biofilm formation in coinfections of Streptococcus suis and Glaesserella parasuis. A) Bar plots showing the quantitative biofilm formation (expressed as the absorbance OD595) of one representative S. suis isolate from each of the four main serovars (SVs) (orange), ten random G. parasuis isolates (green), and their coinfections (blue). B) Scanning electron microscopy (SEM) images of biofilm formation in coinfections between S. suis SV1 and G. parasuis G003 (left) and between S. suis SV9 (969) and G. parasuis G026 (right).
