The Basis for Variations in the Biofilm Formation by Different Salmonella Species and Subspecies: An In Vitro and In Silico Scoping Study

This study examined whether the presence/absence of biofilm-associated genes may indicate potential for differences in biofilm formation among Salmonella species/subspecies. We conducted an vitro on by eighteen strains different Strains belonging to subspecies enterica were generally poorer formers than species bongori and arizonae, diarizonae, indica. A broader silico was subsequently conducted. The 57 further investigated 323 whole genomes various lpfE gene present 88.2% but absent ~90.2–100% other subspecies. sirA 11.8% 2.9% S. diarizonae while lpfe negatively correlated with environmental formation. csrB 71.4% arizonae 94.3% absence positively weaker contribute being better formers.
