Candida albicans Biofilms and Human Disease

Open access
Nobile, Clarissa J., Johnson, Alexander D.·2015·Annual Review of Microbiology

Abstract

In humans, microbial cells (including bacteria, archaea, and fungi) greatly outnumber host cells. Candida albicans is the most prevalent fungal species of the human microbiota; this species asymptomatically colonizes many areas of the body, particularly the gastrointestinal and genitourinary tracts of healthy individuals. Alterations in host immunity, stress, resident microbiota, and other factors can lead to C. albicans overgrowth, causing a wide range of infections, from superficial mucosal to hematogenously disseminated candidiasis. To date, most studies of C. albicans have been carried out in suspension cultures; however, the medical impact of C. albicans (like that of many other microorganisms) depends on its ability to thrive as a biofilm, a closely packed community of cells. Biofilms are notorious for forming on implanted medical devices, including catheters, pacemakers, dentures, and prosthetic joints, which provide a surface and sanctuary for biofilm growth. C. albicans biofilms are intrinsically resistant to conventional antifungal therapeutics, the host immune system, and other environmental perturbations, making biofilm-based infections a significant clinical challenge. Here, we review our current knowledge of biofilms formed by C. albicans and closely related fungal species.

TL;DR

This review summarizes how *Candida albicans* forms biofilms on medical devices and mucosal surfaces, and how these communities resist antifungal drugs and host defenses. It highlights a six-regulator transcriptional network, matrix- and persister-mediated drug resistance, and the clinical burden of biofilm infections.

Key findings

  • *C. albicans* biofilm development proceeds through four stages: adherence of yeast cells, proliferation into a basal layer, growth of pseudohyphae/hyphae with extracellular matrix production, and dispersal of yeast-form cells. Mature biofilms typically form within 24 hours in vitro.
  • Six master transcriptional regulators (Efg1, Tec1, Bcr1, Ndt80, Brg1, Rob1) are each required for biofilm development in vitro and in rat catheter/denture models; together they directly bind and likely regulate approximately 1,000 target genes. The review counts 50 transcriptional regulators and 101 nonregulatory genes with functionally validated biofilm roles.
  • Biofilm resistance involves early and sustained efflux pump upregulation, extracellular matrix components including β-1,3-glucan and extracellular DNA, and metabolically dormant persister cells. Matrix composition is reported as ~55% proteins/glycoproteins, 25% carbohydrates, 15% lipids, and 5% nucleic acids, with over 500 proteins identified.
  • Clinical impact: NIH estimates biofilms account for over 80% of microbial infections in the United States; CTG clade species account for 15% of hospital-acquired sepsis and are the fourth most frequent cause of bloodstream infections; over 5 million central venous catheters are placed annually in the United States (1992–2001 data), with biofilm infection in over 50%; estimated 100,000 deaths and $6.5 billion in excess expenditure annually in the United States; disseminated candidiasis mortality approaches 40% in some cases.

Methods

  • Narrative review of published literature on *C. albicans* and related fungal biofilms; no new experimental data are reported.
  • Synthesizes in vitro biofilm models (e.g., silicone squares, flow cells), in vivo/ex vivo animal models (rat/rabbit catheter, denture stomatitis, vaginal mucosal, bioluminescence), and genetic/genomic/proteomic studies (knockout screens, transcriptional profiling, proteomics).
  • Main analysis is qualitative synthesis, including tables of 50 transcriptional regulators and 101 nonregulatory genes with validated biofilm roles.

Limitations

  • Stated: little is known about persister cell formation and regulation; virtually nothing is known about interactions among *Candida* species in polymicrobial biofilms; the majority of newly identified biofilm-network target genes remain unstudied; the biofilm network outline is “undoubtedly incomplete”; and biofilm formation is often loosely defined in non-*Candida* fungi.
  • Evident: as a review, it does not present primary experimental data, and its conclusions depend on the designs and conditions of cited studies; many mechanistic findings come from in vitro models or non-*C. albicans* species.

    Candida albicans and bacteria can interact with each other by secretion of signaling molecules that influence the behavior of one species toward the other, by direct cell-cell physical contact, and by alterations of the local environment that influence the other species.

    “From these studies, we have learned that C. albicans and bacteria can interact with each other by secretion of signaling molecules that influence the behavior of one species toward the other, by direct cell-cell physical contact, and by alterations of the local environment that influence the other species (e.g., alterations in pH and oxygen concentrations).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Claims read by deepseek-v4.1-flash under definition version 3 (extract-v3) on 2026-10-09.

Classified by jev-1.13-20260917 (gold-guideline-v0.2) on 2026-10-09.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
