Interspecies relationship with Candida spp. growth and biofilm development.

Bacterial speciesEffect on C. albicans hyphal growthEffect on Candida biofilm

Staphylococcus aureus (+)Associates to hyphal cells (56%) [80]No antagonistic effect in dual biofilms with C. albicans (BacLight LIVE/DEAD assay) [80]

Staphylococcus epidermidis (+)Associates to hyphal cells (25%) [80]Reduced adhesion and biofilm formation by a glycocalyx producer strain (CFU counts) [82]

Streptococcus pyogenes (+)Associates to hyphal cells (25%) [80]

Streptococcus mutans and Streptococcus intermediusS. mutans inhibits hyphal formation [89, 90]No significant effect on biofilm viability at densities ranging from 6.25·105 to 1·107 cells/mL (bacteria added to preformed 3-hour-old biofilms; polystyrene in vitro model; CFUs analyses) [81]

Streptococcus gordonii (+)Stimulates hyphal growth [91]Promotes mixed biofilms with C. albicans [91]

Pseudomonas aeruginosa (−)(i) Associates to hyphal cells (17%) [80]
(ii) Reduced hyphal growth in C. albicans-P. aeruginosa dual biofilms [81]
(iii) Binds hyphae and kill C. albicans [92]
(i) Reduced adhesion and biofilm formation by a nonglycocalyx producer strain (CFU counts) [82]
(ii) Reduction of biofilm mass ranging from 40% to 80% in a density-dependent manner [90]
(iii) Mutual biofilm inhibition between Pa and C. albicans, C. krusei and C. glabrata; decreased biofilm formation of C. parapsilosis and C. tropicalis in presence of Pa; increased CFUs of Pa in presence of C. tropicalis [93]

Escherichia coli (−)Associates to hyphal cells (5.7%) [80](i) Reduction of biofilm mass ranging from 50% to 80% [81]
(ii) Mutual decrease in biofilm cell mass between Ec and C. albicans; inhibition of biofilm development by C. tropicalis, C. parapsilosis, C. krusei, and C. dubliniensis; increased Ec cell numbers within C. tropicalis and C. dubliniensis biofilms [94]

Lactobacillus acidophilusInhibition of viable biofilm cell mass by 40% [81]

Bacillus subtilisAssociates to hyphal cells (2.5%) [80]

Actinomyces israelii (+)Some inhibition of biofilm at high densities [81]

Prevotella nigrescens and Porphyromonas gingivalisInhibition of C. albicans hyphal development [95]Reduction of C. albicans biofilms, only at high densities [81]

Klebsiella pneumoniae, Serratia marcescens, and Enterobacter cloacaeDecreased biofilm formation (CFU counts) [82]
