“…The particles were able to disrupt in a similar manner single-species or dual-species biofilms, but it was observed that adhesion of bacteria to Candida hyphae made their surface less accessible to antimicrobial molecules. This obstacle was already described for free antimicrobial molecules in dual-species biofilms of S. aureus and Fusarium falciforme [49]. This interaction between the microbial species was also observed for C. acnes et C. albicans [22] and could participate in the loss of activity of ANCs on C. albicans in the dual-species biofilm.…”

“…This mycophagy event, generated by the bacteria in the HLFC model, has a direct impact over the fungal population, since bacteria are taking advantage of the fungal components for self-nutrition (Leveau and Preston, 2008). Mycophagy events have previously been reported for this Staphylococcus species in other in vitro fungal-bacterial models (Ikeda et al, 2007;Camarillo-Maŕquez et al, 2018;Bautista-Hernańdez et al, 2019). In summary, the correlation of the MTT values with the microscopic evidence obtained by SEM suggests that in this FBI on HLFCs, the prevalent microorganism is S. aureus.…”

“…Similarly, abundant amounts of extracellular material of single and mixed biofilms were demonstrated in the presence of the HLFC monolayers by EFM (Figures 5, 6). This qualitative technique of biofilm has been used by our research group for the detection of biomolecules that constitute the ECM (Ramıŕez Granillo et al, 2015;Gonzaĺez-Ramıŕez et al, 2016;Camarillo-Maŕquez et al, 2018;Bautista-Hernańdez et al, 2019). Other authors have reported that by using molecules to specifically eliminate ECM components, such as sodium periodate (that destroys carbohydrates), DNase (that digests DNA), and proteinase K (that digests proteins), it was possible to demonstrate that fluorochromes detect specifically such biomolecules (Baillie and Douglas, 2000;Chandra et al, 2001;Coŕdova-Alcańtara et al, 2019).…”

“…Additionally, the bacterium Staphylococcus aureus strongly inhibited fungal conidiation, filamentation and consequently biofilm formation of A. fumigatus by direct cellecell contact [91]. This same bacterium was also able to negatively influence the filamentation and biofilm formation of the fungus Fusarium falciforme [92]. Most of these studies were performed within 24 h of interaction, however, with medium renewal and removal of planktonic cells, after that time, an increase in fungal viability could be observed, which could lead to its germination and development into a biofilm [87].…”
