Biofilm formation in coinfections of Streptococcus suis and Pasteurella multocida. 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 P. multocida isolates (green), and their coinfections (blue). B) Scanning electron microscopy (SEM) images of biofilm formation in coinfections between S. suis SV1 (990) and P. multocida PM182 (left) and between S. suis SV7 (998) and P. multocida PM179 (right).
