Candida glabrata: Pathogenicity and Resistance Mechanisms for Adaptation and Survival
Open accessPublished version of a preprint
Abstract
Candida glabrata is a yeast of increasing medical relevance, particularly in critically ill patients. It is the second most isolated Candida species associated with invasive candidiasis (IC) behind C. albicans. The attributed higher incidence is primarily due to an increase in the acquired immunodeficiency syndrome (AIDS) population, cancer, and diabetic patients. The elderly population and the frequent use of indwelling medical devices are also predisposing factors. This work aimed to review various virulence factors that facilitate the survival of pathogenic C. glabrata in IC. The available published research articles related to the pathogenicity of C. glabrata were retrieved and reviewed from four credible databases, mainly Google Scholar, ScienceDirect, PubMed, and Scopus. The articles highlighted many virulence factors associated with pathogenicity in C. glabrata, including adherence to susceptible host surfaces, evading host defences, replicative ageing, and producing hydrolytic enzymes (e.g., phospholipases, proteases, and haemolysins). The factors facilitate infection initiation. Other virulent factors include iron regulation and genetic mutations. Accordingly, biofilm production, tolerance to high-stress environments, resistance to neutrophil killings, and development of resistance to antifungal drugs, notably to fluconazole and other azole derivatives, were reported. The review provided evident pathogenic mechanisms and antifungal resistance associated with C. glabrata in ensuring its sustenance and survival.
Overview

Written from the paper’s full text.
TL;DR
This review summarizes virulence and antifungal resistance mechanisms that enable *Candida glabrata* to colonize, evade host immunity, and survive therapy. It highlights adhesion, biofilm formation, stress adaptation, replicative ageing, iron acquisition, and azole/echinocandin resistance as key contributors to its clinical persistence.
Key findings
- *C. glabrata* is the second most frequently isolated *Candida* species in invasive candidiasis after *C. albicans*, accounting for approximately 15–25% of invasive clinical cases; invasive candidiasis due to *C. glabrata* has an estimated morbidity and mortality of approximately 40–60%.
- Virulence factors include hydrolytic enzymes (phospholipases, proteases, haemolysins), epithelial adhesin (EPA)-family adhesins, sparse yeast-cell biofilms, cell wall/chitin remodeling, iron acquisition, environmental stress adaptation, and replicative ageing; *C. glabrata* lacks hyphal formation and provokes a weaker host immune response than *C. albicans*.
- Resistance mechanisms include intrinsic and acquired fluconazole resistance, azole resistance via *ERG11* mutations, *PDR1* gain-of-function mutations, efflux pumps, aneuploidy, and mitochondrial dysfunction; echinocandin resistance is around 4% in *C. glabrata* and less than 1% in *C. albicans*, primarily through *FKS1* and *FKS2* hotspot mutations.
- Biofilm formation on medical devices contributes to drug tolerance, and the review states that an estimated 65% of all human infections are of biofilm aetiology.
Methods
- Narrative review of published research articles related to *C. glabrata* pathogenicity, retrieved from four credible databases: Google Scholar, ScienceDirect, PubMed, and Scopus.
- The paper synthesizes cited studies on virulence factors, host–pathogen interactions, and antifungal resistance mechanisms; it reports no primary experiments or new data.
- No systematic search dates, inclusion/exclusion criteria, or quality appraisal methods are described in the text.
Limitations
- The paper has no formal limitations section; it states that the exact azole resistance mechanism is not entirely clear, iron homeostasis mechanisms in *C. glabrata* remain unknown, it is unclear how *Candida* biofilm structure affects mucosal infection and host immunity, and acid stress tolerance has not been extensively investigated.
- Evident from the text: as a narrative review, it lacks a systematic search strategy, quantitative synthesis, and formal risk-of-bias assessment.
- Evident from the text: many cited findings derive from in vitro assays or murine models, which may limit direct clinical generalizability.

The authors state this as an assumption.
The mechanisms of biofilm resistance include elevated cellular density, exopolymeric protective effect, differential upregulation of resistance genes and efflux pumps, and a subpopulation within the biofilm community.
“The resistance development due to biofilm is complex and multifactorial; among the assumed mechanisms are (i) the elevated cellular density within the biofilm, (ii) the exopolymeric protective effect of the biofilm, (iii) differential upregulation of genes linked to resistance and those encoding efflux pumps, and (iv) the presence of a subpopulation within the biofilm community.”
The paper relies on this without support.
The four databases Google Scholar, ScienceDirect, PubMed, and Scopus cover the relevant published research on C. glabrata pathogenicity.
“The available published research articles related to the pathogenicity of C. glabrata were retrieved and reviewed from four credible databases, mainly Google Scholar, ScienceDirect, PubMed, and Scopus.”

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.
A language model drew the claims from the paper on 2026-10-09, under version 3 of the claim definition (model deepseek-v4.1-flash, prompt extract-v3).
A second model labelled each claim on 2026-10-09 (model jev-1.13-20260917, definition revision gold-guideline-v0.2).
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.
