Combination of QSMs with colistin or fluconazole was found to be effective against both single- and dual-species biofilms in vitro. Increased survival was observed in C. elegans when treated with colistin or fluconazole in combination with QSMs, compared with no treatment. Additionally, the QSMs and colistin and farnesol combinations effectively inhibited biofilm formation by C. albicans and P. aeruginosa on bronchial epithelial cells, and reduced IL-1\u03b2 expression in lung bronchial epithelial cells.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>There is a need for effective treatments for bacterial-fungal biofilm infections and, to our knowledge, there have been no studies of QSMs and antimicrobial combinations against dual-species biofilms involving C. albicans and P. aeruginosa.
