Interaction between bacterial adhesins leads to coaggregation by the oral bacteria Veillonella parvula and Streptococcus gordonii | mBio Veillonella spp. are common, obligately anaerobic members of the oral microbiota belonging to the phylum Bacillota (formerly Firmicutes). Most members of this phylum have a classically Gram-positive cell structure; however, veillonellae (and other members of the class Negativicutes) are atypical in this group, as they have a diderm cell envelope, i.e., having an outer membrane similar to classical Gram-negative bacteria, though with some notable differences in biogenesis and homeostatic mechanisms (1, 2). Veillonellae contribute to the formation of dental plaque by binding to early colonizers of the tooth surface (mostly streptococci) and then recruiting late colonizers to the forming biofilm, including pathogenic species like Porphyromonas gingivalis and Treponema denticola. Veillonellae can, therefore, be considered ecological keystone species important for oral biofilm formation (3). The ability of veillonellae to bridge the early and late plaque colonizers depends on the phenomenon of coaggregation, where microbes of different species bind to each other through mutually attractive interactions (4). In the case of veillonellae, coaggregation is beneficial, as these organisms then metabolize the lactate produced by their coaggregating partners.
