Project description:Members of the genus Candida, such as C. albicans and C. parapsilosis, are important human pathogens. Other members of this genus, previously believed to carry minimal disease risk, are increasingly recognised as important human pathogens, particularly because of variations in susceptibilities to widely used anti-fungal agents. Thus, rapid and accurate identification of clinical Candida isolates is fundamental in ensuring timely and effective treatments are delivered. Rapid Evaporative Ionisation Mass Spectrometry (REIMS) has previously been shown to provide a high-throughput platform for the rapid and accurate identification of bacterial and fungal isolates. In comparison to commercially available matrix assisted laser desorption ionisation time of flight mass spectrometry (MALDI-ToF), REIMS based methods require no preparative steps nor time-consuming cell extractions. Here, we report on the ability of REIMS-based analysis to rapidly and accurately identify 153 clinical Candida isolates to species level. Both handheld bipolar REIMS and high-throughput REIMS platforms showed high levels of species classification accuracy, with 96% and 100% of isolates classified correctly to species level respectively. In addition, significantly different (FDR corrected P value < 0.05) lipids within the 600 to 1000 m/z mass range were identified, which could act as species-specific biomarkers in complex microbial communities.

Project description:<p><em>Candida</em> species are the most common cause of opportunistic fungal infections. Rapid identification and novel approaches for the characterization of these fungi are of great interest to improve the diagnosis and the knowledge about their pathogenic properties. This study aimed to characterize clinical isolates of <em>Candida</em> spp. by proteomics (MALDI-TOF MS) and metabolomics (<sup>1</sup>H-NMR), and to correlate their metabolic profiles with <em>Candida</em> species, source of infection and different virulence associated parameters. In particular, 49 <em>Candida</em> strains from different sources (blood, n = 15; vagina, n = 18; respiratory tract, n = 16), belonging mainly to <em>C. albicans</em> complex (61%), <em>C. glabrata</em> (20%) and <em>C. parapsilosis</em> (12%) species were used. Several extracellular and intracellular metabolites showed significantly different concentrations among isolates recovered from different sources of infection, as well as among different <em>Candida</em> species. These metabolites were mainly related to the glycolysis or gluconeogenesis, tricarboxylic acid cycle, nucleic acid synthesis and amino acid and lipid metabolism. Moreover, we found specific metabolic fingerprints associated with the ability to form biofilm, the antifungal resistance (i.e. caspofungin and fluconazole) and the production of secreted aspartyl proteinase. In conclusion, <sup>1</sup>H-NMR-based metabolomics can be useful to deepen <em>Candida</em> spp. virulence and pathogenicity properties.</p>

Project description:In recent years, microbiome studies revealed that Candida species are common colonisers of the human skin. The distribution of species however varies greatly. Although C. parapsilosis is more likely to resemble skin commensals, opinions are divided, and discrepancies are present regarding C. albicans, that is also often associated with cutaneous candidiasis. Therefore, we aimed to thoroughly assess the nature of skin epithelial cell - Candida interactions. To study species-specific host reponses, we examined phagocytosis, cytokine and metabolic responses in different keratinocytes (HaCaT, HPV-KER) along with host cell damage following fungal stimuli. These results suggest that C. albicans triggers an enhanced antifungal response, thus does not closely resembe skin commensals, like C. parapsilosis. Furthermore, HPV-KER might serve as a more applicable tool for studying keratinocyte antifungal responses. To rigorously examine yeast-keratinocyte interactions, we applied two distinct isolates of both C. albicans (SC5314, WO-1) and C. parapsilosis (GA1, CLIB214). Comparison of the two fungi’s virulence revealed that while C. albicans effectively adheres to human keratinocytes and causes subsequent damage, C. parapsilosis is unable to establish lasting physical contact and causes less harm. In terms of keratinocyte response, both cell lines showed significantly enhanced cellular (% phagocytosis), humoral (IL-6, IL-8) and metabolic responses (2-ketoglutaric acid, citric acid, threorine, hypotaurine) to C. albicans strains, while those towards C. parapsilosis remained relatively low or similar to the control condition. Under certain conditions strain preference was also detected. Of the two cell lines, HPV-KER was more sensitive, as besides interspecies differences, intraspecies differences were also measurable.
