These infections exhibit increased resilience, due to microbial interactions that also disrupt host immune responses. Current research focuses on virulence and disease-promoting interactions, but less is known about interactions that could inhibit or prevent disease development. Normally human-associated microbiomes maintain homeostasis, preventing pathobionts from becoming dominant. In conditions like chronic disseminated candidiasis or severe early childhood caries (s-ECC), an overgrowth of microbes such as\n              <jats:italic>Candida albicans<\/jats:italic>\n              disrupts this balance. Typically,\n              <jats:italic>C. albicans<\/jats:italic>\n              coexists benignly within the microbial community but can become pathogenic, forming biofilms and interacting with other microbes such as cariogenic\n              <jats:italic>Streptococcus mutans<\/jats:italic>\n              . This interaction is particularly significant in s-ECC, where it exacerbates the disease\u2019s progression and severity. Here, we present that\n              <jats:italic>Corynebacterium durum<\/jats:italic>\n              , itself and through its extracellular membrane vesicles disrupts interkingdom assemblages between\n              <jats:italic>C. albicans<\/jats:italic>\n              and\n              <jats:italic>S. mutans<\/jats:italic>\n              . Mechanistically the interaction interference occurs at the genetic level with downregulated HWP1 expression, a surface protein specifically induced in the presence of\n              <jats:italic>S. mutans<\/jats:italic>\n              promoting the interkingdom interaction. Additionally, we show that\n              <jats:italic>C. durum<\/jats:italic>\n              can impede\n              <jats:italic>C. albican<\/jats:italic>\n              s systemic virulence in the\n              <jats:italic>Galleria mellonella<\/jats:italic>\n              infection model. This suggests that oral corynebacteria may act as a beneficial commensal species, exerting antifungal effects within polymicrobial communities and opening new avenues for managing polymicrobial diseases.\n            <\/jats:p>\n            <jats:sec>\n              <jats:title>IMPORTANCE<\/jats:title>\n              <jats:p>\n                Polymicrobial diseases such as severe early childhood caries (s-ECC) lack effective treatment options. Prevention, requiring a deeper understanding of ecological processes before the onset of disease symptoms, could be a potential strategy. In this context, we investigated how relatively abundant oral biofilm\n                <jats:italic>Corynebacterium<\/jats:italic>\n                species, which are associated with oral health, can interfere with the interkingdom partnership of\n                <jats:italic>Streptococcus mutans<\/jats:italic>\n                and\n                <jats:italic>Candida albicans<\/jats:italic>\n                . This partnership is a significant driver of tooth decay in s-ECC due to synergistic activities that increase cariogenicity. Our study reveals that oral corynebacteria, through the production of extracellular membrane vesicles, can disrupt the\n                <jats:italic>S. mutans<\/jats:italic>\n                and\n                <jats:italic>C. albicans<\/jats:italic>\n                partnership by inhibiting fungal hyphae formation. Additionally, the fatty acid cargo within these vesicles exhibits antifungal properties, suggesting that corynebacteria play a role in shaping microbial dynamics within the oral biofilm.\n
