- Bacteria can be motile and planktonic or, alteRNAtively, sessile and participating in the biofilm mode of growth. The transition between these lifestyles can be regulated by a second messenger, cyclic dimeric GMP (c-di-GMP). High intracellular c-di-GMP concentration correlates with biofilm formation and motility inhibition in most bacteria, including Bordetella bronchiseptica, which causes respiratory tract infections in mammals and forms biofilms in infected mice. We previously described the diguanylate cyclase BdcA as involved in c-di-GMP synthesis and motility regulation in B. bronchiseptica; here, we further describe the mechanism whereby BdcA is able to regulate motility and biofilm formation. Amino acid replacement of GGDEF with GGAAF in BdcA is consistent with the conclusion that diguanylate cyclase activity is necessary for biofilm formation and motility regulation, although we were unable to confirm the stability of the mutant protein. In the absence of the bdcA gene, B. bronchiseptica showed enhanced motility, strengthening the hypothesis that BdcA regulates motility in B. bronchiseptica. We showed that c-di-GMP-mediated motility inhibition involved regulation of flagellin expression, as high c-di-GMP levels achieved by expressing BdcA significantly reduced the level of flagellin protein. We also demonstrated that protein BB2109 is necessary for BdcA activity, motility inhibition, and biofilm formation. Finally, absence of the bdcA gene affected bacterial infection, implicating BdcA-regulated functions as important for bacterium-host interactions. This work supports the role of c-di-GMP in biofilm formation and motility regulation in B. bronchiseptica, as well as its impact on pathogenesis. IMPORTANCE Pathogenesis of Bordetella spp., like that of a number of other pathogens, involves biofilm formation. Biofilms increase tolerance to biotic and abiotic factors and are proposed as reservoirs of microbes for transmission to other organs (trachea, lungs) or other hosts. Bis-(3=-5=)-cyclic dimeric GMP (c-di-GMP) is a second messenger that regulates transition between biofilm and planktonic lifestyles. In Bordetella bronchiseptica, high c-di-GMP levels inhibit motility and favor biofilm formation. In the present work, we characterized a B. bronchiseptica diguanylate cyclase, BdcA, which regulates motility and biofilm formation and affects the ability of B. bronchiseptica to colonize the murine respiratory tract. These results provide us with a better understanding of how B. bronchiseptica can infect a host.
