Identification of <Emphasis Type="Italic">Candida</Emphasis> Species Isolated from Bovine Mastitic Milk and Their In Vitro Hemolytic Activity in Western Turkey

In this study, identification of 207 Candida isolates, previously isolated from mastitic bovine quarter milk samples at the level of genus, was made using API 20 C AUX system. The most frequently isolated species were Candida krusei (34.8%), followed by Candida rugosa (16.4%), Candida kefyr (12.6%), Candida albicans (10.1%), and Candida tropicalis (9.2%). Less common isolates were Candida zeylanoides (5.8%), Candida parapsilosis (4.3%), Candida guilliermondii (3.4%), Candida famata (1.9%), and Candida glabrata (1.5%). Additionally, in vitro hemolytic activity of all Candida strains were also examined in the present study. C. krusei (72 isolates), C. kefyr (26), C. albicans (21), C. tropicalis (19), C. zeylanoides (12), and C. glabrata (3) demonstrated both alpha and beta hemolysis at 48-h postinoculation. Only alpha hemolysis was detected in C. rugosa (34), C. guilliermondii (7), and C. famata (4), while C. parapsilosis (9) did not show any hemolytic activity after incubation for 72 h. Statistically significant difference (P < 0.001) was determined between the beta-hemolytic activities of Candida strains. The hemolytic activities of C. zeylanoides, C. albicans and C. kefyr were higher than other strains. This is the first study to describe variable hemolysis types exhibited by different Candida strains isolated from bovine mastitic milk in Turkey.     

How much do we know about hemolytic capability of pathogenic <Emphasis Type="Italic">Candida</Emphasis> species?

Hemolytic factor production by pathogenic Candida species is considered an important attribute in promoting survival within the mammal host through the ability to assimilate iron from the hemoglobin-heme group. Hemolytic capability has been evaluated for Candida species based on hemolysis zones on plate assay, analysis of hemolytic activity in liquid culture medium, and hemolysis from cell-free culture broth. The production of hemolytic factor is variable among Candida species, where C. parapsilosis is the less hemolytic species. In general, no intraspecies differences in beta-hemolytic activities are found among isolates belonging to C. albicans, C. glabrata, C. krusei, C. tropicalis, and C. parapsilosis. The production of hemolytic factor by Candida species is affected by several factors such as glucose supplementation in the culture medium, blood source, presence of erythrocytes and hemoglobin, and presence of electrolytes. On the basis of existing achievements, more researches are still needed in order to extend our knowledge about the biochemical nature of hemolytic molecules produced by distinct Candida species, the mechanism of hemolysis, and the molecular basis of the hemolytic factor expression.     

Etiología de la candidiasis en pediatría: análisis comparativo con el paciente adulto

BackgroundCandida spp. represents a group of commensal yeasts that can act as pathogens and cause candidiasis in different anatomical locations.AimsThe aim of this study was to perform an epidemiological and comparative analysis between the isolates of Candida spp. in clinical specimens during a three year-period (2010-2012) from children (0-14 years) and adults (15-99 years) in the Valencian Community (RedMIVA).MethodsThe microbiological surveillance network of Valencian Community was used as the information source.Results and conclusionsCandida was isolated in 52,436 patients (1,604 [3.1%] children and 50,832 [96.9%] adults). Candida albicans was significantly (p < 0.05) the predominant species in both age groups, and in almost every type of clinical specimen. The distribution of other species varied depending on the sample type and age group. In blood specimens, Candida parapsilosis followed by C. albicans, Candida famata and Candida lusitaniae were the main species found in children, whereas C. albicans followed by C. parapsilosis, Candida glabrata and Candida tropicalis were the predominant species in adults. In sterile fluids, urine and lower respiratory tract samples, C. parapsilosis was the second most prevalent species in the children group, while C. glabrata and C. tropicalis were the main second species in adults.     

Multi-probe Real-Time PCR Identification of Four Common Candida Species in Blood Culture Broth

We developed a single-tube real-time polymerase chain reaction (PCR) assay with multiple hybridization probes for detecting Candida albicans, C. tropicalis, C. glabrata, and C. parapsilosis. Primers were designed to amplify 18S rRNA gene of the genus Candida, and DNA probes were designed to hybridize two areas of the amplicons. The amplification curves and specific melting peaks of the probes hybridized with PCR product were used for definite species identifications. The reaction specificity was 100 % when evaluating the assay using DNA samples from 21 isolates of fungal and bacterial species. The assay was further evaluated in 129 fungal blood culture broth samples which were culture positive for fungus. Of the 129 samples, 119 were positively identified as: C. albicans (39), C. tropicalis (30), C. parapsilosis (23), C. glabrata (20), Candida spp. (5), and two samples containing mixed C. glabrata/C. albicans and C. glabrata/C. tropicalis. The five Candida spp. were identified by sequencing analysis as C. krusei, C. dubliniensis, C. aquaetextoris, and two isolates of C. athensensis. Of the ten samples which showed negative PCR results, six were Cryptococcus neoformans, and the others were Trichosporon sp., Rhodotorula sp., Fusarium sp., and Penicillium marneffei. Our findings show that the assay was highly effective in identifying the four medically important Candida species. The results can be available within 3 h after positivity of a blood culture broth sample.     

Usefulness of the Non-conventional <Emphasis Type="Italic">Caenorhabditis elegans</Emphasis> Model to Assess <Emphasis Type="Italic">Candida</Emphasis> Virulence

Invasive candidiasis is caused mainly by Candida albicans, but other Candida species have increasing etiologies. These species show different virulence and susceptibility levels to antifungal drugs. The aims of this study were to evaluate the usefulness of the non-conventional model Caenorhabditis elegans to assess the in vivo virulence of seven different Candida species and to compare the virulence in vivo with the in vitro production of proteinases and phospholipases, hemolytic activity and biofilm development capacity. One culture collection strain of each of seven Candida species (C. albicans, Candida dubliniensis, Candida glabrata, Candida krusei, Candida metapsilosis, Candida orthopsilosis and Candida parapsilosis) was studied. A double mutant C. elegans AU37 strain (glp-4;sek-1) was infected with Candida by ingestion, and the analysis of nematode survival was performed in liquid medium every 24 h until 120 h. Candida establishes a persistent lethal infection in the C. elegans intestinal tract. C. albicans and C. krusei were the most pathogenic species, whereas C. dubliniensis infection showed the lowest mortality. C. albicans was the only species with phospholipase activity, was the greatest producer of aspartyl proteinase and had a higher hemolytic activity. C. albicans and C. krusei caused higher mortality than the rest of the Candida species studied in the C. elegans model of candidiasis.     

Species Distribution and Virulence Factors of Candida spp. Isolated from the Oral Cavity of Kidney Transplant Recipients in Brazil

Although yeasts belonging to the genus Candida are frequently seen as commensals in the oral cavity, they possess virulence attributes that contribute for pathogenicity. The aims of the present study were to study the prevalence of Candida spp. isolated from the oral cavity of renal transplant recipients and to analyze strains virulence factors. We isolated a total of 70 Candida strains from 111 transplant recipients, and Candida albicans was the most prevalent species (82.86 %). Oral candidiasis was diagnosed in 14.4 % kidney transplant patients, while 11 isolates (15.7 %) corresponded to non-Candida albicans Candida (NCAC) species. C. albicans adhered to a higher extension than NCAC strains. Some isolates of Candida tropicalis were markedly adherent to human buccal epithelial cells and highly biofilm-forming strains. Regarding proteinase activity, Candida orthopsilosis was more proteolytic than Candida metapsilosis. Candida glabrata and Candida dubliniensis showed very low ability to form biofilm on polystyrene microtiter plates. We have demonstrated here diverse peculiarities of different Candida species regarding the ability to express virulence factors. This study will contribute for the understanding of the natural history and pathogenesis of yeasts belonging to the genus Candida in the oral cavity of patients who were submitted to kidney transplant and are under immunosuppressive therapies.     

Lack of relationship between genotype and virulence in Candida species

BackgroundThe virulence of isolates among different Candida species causing candidemia may play a role in the prognosis of the patients. Furthermore, the potential relationship between genotype and virulence is still unclear and need to be further studied.AimsWe aim to assess the relationship between genotype and virulence in Candida species using a Galleria mellonella larvae infection model.MethodsOne hundred and ninety-four isolates from 68 clusters (Candida albicans, 114/41; Candida parapsilosis, 74/24; Candida tropicalis, 6/3) were compared against the same number of each species singleton genotypes in terms of survival of G. mellonella larvae.ResultsThe median of survival and the IQR ranges of clusters and singleton were as follows: C. albicans (2 days, IQR 1.5–2 vs. 2 days, IQR 1–2.25), C. parapsilosis (2 days, IQR 1.5–2.6 vs. 2 days, IQR 2–3.3), and C. tropicalis (1 day, IQR 1–3.5 vs. 2 days, IQR 2–3.5; p < 0.05). High intra-cluster variability in terms of median of survival was found regardless the species.ConclusionsNo relationship between genotype and virulence in Candida was observed with the G. mellonella model.     

Candida albicans and Non-C. albicans Candida Species: Comparison of Biofilm Production and Metabolic Activity in Biofilms, and Putative Virulence Properties of Isolates from Hospital Environments and Infections

Candida albicans and, more recently, non-C. albicans Candida spp. are considered the most frequent fungi in hospitals. This study analyzed Candida spp. isolates and compared the frequency of different species, that is, C. albicans and non-C. albicans Candida spp., and the origins of isolates, that is, from hospital environments or infections. Yeast virulence factors were evaluated based on biofilm production and metabolic activity. Hemolysin production and the antifungal susceptibility profiles of isolates were also evaluated. Candida spp. were highly prevalent in samples collected from hospital environments, which may provide a reservoir for continuous infections with these yeasts. There were no differences in the biofilm productivity levels and metabolic activities of the environmental and clinical isolates, although the metabolic activities of non-C. albicans Candida spp. biofilms were greater than those of the C. albicans biofilms (p < 0.05). Clinical samples had higher hemolysin production (p < 0.05) and lower susceptibility to fluconazole (p < 0.05). Non-C. albicans Candida spp. predominated in samples collected from hospital environments and infections (p < 0.05). These species had a lower susceptibility to fluconazole and amphotericin B, and their biofilms had higher metabolic activities than those produced by C. albicans, which may explain the increased incidence of fungal infections with these yeasts during recent years.     

In Vitro Susceptibility of Candida Isolates from Organ Transplant Recipients to Newer Antifungals

Organ transplant recipients (OTR) are at higher risk of developing life-threatening infections. In this study, we tested 527 Candida isolates obtained from the oral and genital mucosa from OTR and healthy controls in order to monitor antifungal susceptibility patterns in this particular risk group. Testing was carried out in parallel for already marketed azoles and anidulafungin. Minimal inhibitory concentrations (MICs) were determined using the E-test^® for azoles and CLSI broth microdilution for anidulafungin. Overall, there was no difference in the distribution of Candida spp. for both groups, C. albicans being the most frequently isolated Candida sp. followed by C. glabrata. Also, there were only minor differences in the susceptibility patterns to all antifungal agents. All C. albicans isolates were fully susceptible to fluconazole and voriconazole. In C. glabrata, 2.2 % (n = 1) were resistant to fluconazole, and 82.6 % (n = 38) to itraconazole, and in C. krusei, 66.7 % (n = 2) were resistant in itraconazole. All strains were susceptible to voriconazole. Only fluconazole showed a higher rate of resistant C. glabrata isolates for OTR (3.7 %), whereas the control group showed only intermediate susceptible and no resistant isolates. As there are no breakpoints established for posaconazole by CLSI, breakpoints determined by EUCAST were used. A total of 87.9 % of C. albicans, 81.3 % of C. parapsilosis and 66.7 % of C. tropicalis were considered susceptible. C. glabrata and C. krusei showed higher MIC values and thus lesser susceptibility than the other Candida species. There were no differences observed between OTR and control groups. For anidulafungin, 99.8 % of C. albicans isolates were susceptible, 0.2 % were intermediate, whereas for C. glabrata, only 95.3 % were susceptible, 0.2 % were resistant and 4.5 % were interpreted as intermediate. Interestingly, the two resistant isolates were found in the control group. Also, the controls showed a marginally higher percentage of intermediate strains compared to the transplant patients. All in all, resistant isolates were only observed for C. glabrata of the control group.     

Nosocomial Bloodstream Candida Infections in a Tertiary-Care Hospital in South Brazil: A 4-Year Survey

The aims of this study were to evaluate the epidemiology of nosocomial candidemia in a tertiary hospital in South Brazil and the in vitro antifungal susceptibility of isolates. Blood strains from 108 patients were identified by PCR-based method. Some 30.5 % of candidemia were caused by Candida tropicalis, 28.7 % were due to Candida albicans, 24.1 % with Candida parapsilosis sensu stricto, 8.3 % with Candida glabrata sensu lato, 1.8 % involved Candida krusei and 6.6 % with other species. Candidemia was more common in intensive care unit settings (66 %). In vitro susceptibility to antifungal drugs was determined by a microdilution method; and new species-specific clinical breakpoints for fluconazole and voriconazole were applied. Overall susceptibility rates were 100 % for itraconazole, 91 % for fluconazole, 98 % for voriconazole and 99 % for amphotericin B. Fluconazole resistance was mostly among C. parapsilosis sensu stricto isolates (26.9 %). Most of the findings reported here agreed with epidemiological features common to other tertiary hospitals in Brazil; but also revealed some peculiarities, such as a high frequency of C. tropicalis associated with candidemia. Besides, high rate of fluconazole resistance among C. parapsilosis stricto sensu isolates was obtained when applying the new species-specific clinical breakpoints.     

Oral Candida carriage of patients attending a dental clinic in Braga,Portugal

BackgroundThe ability of the Candida species to colonize surfaces can be considered as a risk factor for oral infection.AimsTo establish oral Candida carriage in patients attending a dental clinic in Braga, Portugal.MethodsA total of 97 patients were analysed. Swab samples were collected and directly cultured onto CHROMagar Candida. Representative yeasts were identified by polymerase chain reaction.ResultsFrom the samples analysed 54.6% (n=53) were Candida positive, and Candida albicans was the most frequently isolated species, accounting for 79% of all the species identified. Non-C. albicans Candida (NCAC) species recovered included Candida parapsilosis, Candida glabrata, Candida tropicalis, and Candida guilliermondii. There was a lack of association between the presence of C. albicans or NCAC species, and age, gender, or prostheses wearing in this population. In 17% of the cases (n=9), polymicrobial cultures, with two different Candida species, were identified.ConclusionsThis study shows a high Candida carriage rate among this population, thus pointing to the relevance of an accurate diagnostic approach in Candida species identification.     

Characterization,enzymatic activity and biofilm formation of Candida species isolated from goat milk

BackgroundData regarding yeast microbiota in goat milk is scarce.AimsTo isolate and identify species of the genus Candida in milk samples from clinically healthy goats, and evaluate their enzymatic activity and biofilm formation.Methods1092 milk samples from clinically healthy goats were collected and processed. The yeast isolates were identified by phenotypic, methods and their enzymatic activity (phospholipase, hemolysin and protease) and biofilm formation evaluated.ResultsWe obtained 221 Candida isolates belonging to six species: Candida kefyr (35.7%), Candida guilliermondii (33%), Candida famata (23.5%), Candida glabrata (5.9%), Candida albicans (1.35%) and Candida parapsilosis sensu lato (0.45%). Protease activity was detected in all Candida species while hemolysin activity was only present in C. kefyr, C. guilliermondii, C. famata and C. albicans. Only C. albicans showed phospholipase activity. With the exception of C. parapsilosis sensu lato, all Candida species formed biofilm, with 60.19% of the isolates being poor producers, 9.93% moderate producers, and 1.35% strong producers.ConclusionsThe milk of clinically healthy goats contains several species of the genus Candida that could play a role as opportunistic pathogens in mastitis.     

Molecular Identification of <Emphasis Type="Italic">Candida orthopsilosis</Emphasis> Isolated from Blood Culture

The incidence of candidemia and invasive candidiasis have increased markedly due to the increasing number of immunocompromised patients. There are five major medically important species of Candida with their frequency of isolation in the diminishing order namely Candida albicans, Candida parapsilosis, Candida tropicalis, Candida glabrata and Candida krusei. In addition, there are numerous other species of Candida which differ in their genetic makeup, virulence properties, drug susceptibilities and sugar assimilation capabilities. In this report, an unusual Candida species was isolated from the blood of two leukaemic patients. Conventional culture and biochemical tests identified the Candida species as C. parapsilosis. Using fungal-specific oligonucleotide primers ITS1 and ITS4, we managed to amplify the ribosomal RNA gene and its internal transcribed spacer region from the genomic DNA of these isolates. The PCR products were then purified and subjected to automated DNA sequencing using BLAST and CLUSTAL sequence analysis identified these isolates to be Candida orthopsilosis. Candida orthopsilosis is a new species recently identified in 2005, being morphologically indistinguishable from C. parapsilosis and was previously classified as a subspecies of C. parapsilosis. This report highlights the importance of complementing traditional culture and biochemical-based identification methods with DNA-based molecular assays such as PCR as the latter is more superior in terms of its discriminatory power and speed.     

Heteroduplex mobility assay of the 26S rDNA D1/D2 region for differentiation of clinically relevant Candida species

The Heteroduplex Mobility Assay (HMA) method using the PCR amplified D1/D2 region of the 26S rDNA was tested for the differentiation of clinically relevant Candida species. Strains belonging to the same species are not expected to form heteroduplexes in this assay when their PCR products are mixed. D1/D2 HMA experiments between all Candida type strains tested showed heteroduplex formation, including Candida albicans and Candida dubliniensis. There was no heteroduplex formation when most clinical and non-type strains were tested against the type strain of their presumptive species, except when C. albicans WVE and C.␣dubliniensis TAI were analysed. Additional HMA experiments, phenotypic characterisation, and D1/D2 sequencing identified these isolates as Candida tropicalis and Candida parapsilosis, respectively. HMA provides a rapid and relatively simple molecular tool for the differentiation of potentially pathogenic Candida species.     

Antifungal Activity of Chitosan-Coated Poly(lactic-co-glycolic) Acid Nanoparticles Containing Amphotericin B

Amphotericin B (AmB) is one of the most used drugs for the treatment of systemic fungal infections; however, the treatment causes several toxic manifestations, including nephrotoxicity and hemolytic anemia. Chitosan-coated poly(lactide-co-glycolide) (PLGA) nanoparticles containing AmB were developed with the aim to decrease AmB toxicity and propose the oral route for AmB delivery. In this work, the antifungal efficacy of chitosan-coated PLGA nanoparticles containing AmB was evaluated in 20 strains of fungus isolates from patients with vulvovaginal candidiasis (01 Candida glabrata and 03 Candida albicans), bloodstream infections (04 C. albicans and 01 C. tropicalis) and patients with urinary tract infection (04 Candida albicans, 02 Trichosporon asahii, 01 C. guilhermondii, 03 C. glabrata) and 01 Candida albicans ATCC 90028. Moreover, the cytotoxicity over erythrocytes was evaluated. The single-emulsion solvent evaporation method was suitable for obtaining chitosan-coated PGLA nanoparticles containing AmB. Nanoparticles were spherical in shape, presented mean particle size about 460 nm, positive zeta potential and encapsulation efficiency of 42%. Moreover, nanoparticles prolonged the AmB release. All the strains were susceptible to plain AmB and nanostructured AmB, according to EUCAST breakpoint version 8.1 (resistant > 1 μg/mL), using broth microdilution method. In C. albicans (urine, blood, and vulvovaginal secretion isolates, and 1 ATCC), the MIC value of AmB-loaded nanoparticles varied from 0.25 to 0.5 μg/mL and EUCAST varied from 0.03 to 0.5 μg/mL. In urine and vulvovaginal secretion isolates of C. glabrata, the MIC value of AmB-loaded nanoparticles varied from 0.25 to 0.5 μg/mL and EUCAST varied from 0.03 to 0.015 μg/mL. In urine isolates of C. guilhermondii, the MIC value of AmB-loaded nanoparticles was 0.12 μg/mL and EUCAST was 0.06 μg/mL. In blood isolates of C. tropicalis, the MIC value of AmB-loaded nanoparticles was 0.5 μg/mL and EUCAST was 0.25 μg/mL. Finally, in urine isolates of T asahii, the MIC value of AmB-loaded nanoparticles was 1 μg/mL and EUCAST varied from 0.5 to 1 μg/mL. In the cytotoxicity assay, plain AmB was highly hemolytic (100% in 24 h) while AmB-loaded chitosan/PLGA nanoparticles presented negligible hemolysis.     

In vitro susceptibility to 5-fluorocytosine and nystatin of common clinical yeast isolates

The sensitivity to nystatin, 5-fluorocytosine (5-FC) or both was studied for 131 clinical isolates of Candida albicans, 47 of Candida parapsilosis, 34 of Candida tropicalis, 7 of Candida guilliermondii, 28 of Torulopsis glabrata and 1 of Torulopsis Candida.All strains were inhibited by concentrations of nystatin within the usual range of sensitivity except one strain of T. glabrata and another of T. Candida whose minima inhibitory concentrations (MICs) were respectively 250 U/ml and > 20000 U/ml.In respect to 5-FC it was found, after 7 days of incubation at 37 °C, the following frequencies of resistance: C. albicans 28/106 (26%), C. parapsilosis 11/47 (23%), C. tropicalis 24/34 (71%), C. guilliermondii 1/7, T. glabrata 1/28 (4%) and T. candida 0/1. It was particularly striking the activity of 5-FC against T. glabrata.     

Response to Oxidative Stress in Eight Pathogenic Yeast Species of the Genus <Emphasis Type="Italic">Candida</Emphasis>

In the course of an infection, the formation of reactive oxygen species by phagocytes and the antioxidant defense mechanisms of microorganisms play a crucial role in pathogenesis. In this study, isolates representing 8 pathogenic Candida species—Candida albicans, Candida dubliniensis, Candida famata, Candida glabrata, Candida guilliermondii, Candida krusei, Candida parapsilosis and Candida tropicalis—were compared with regard to their resistance to oxidative stress in vitro. We evaluated degree of resistance, induction of oxidative damage, capacity to adapt, and induction of antioxidant enzymes. The species showed variable sensitivity to oxidative attack. C. albicans, C. glabrata, and C. krusei were more resistant to oxidative stress under the conditions tested; C. parapsilosis and C. tropicalis presented medium resistance; and C. dubliniensis, C. famata, and C. guilliermondii were more sensitive. The overall greater resistance to oxidative stress of C. albicans and C. glabrata may provide an advantage to these species, which are the major causative agents of candidiasis.     

Candida species in tchapalo and bangui, two traditional alcoholic beverages from Côte d'Ivoire

The increase of infections due to non-Candida albicans species made it very necessary to conduct adequate characterization to be able to identify the species of Candida isolated from traditional fermented foods. In this study, based on their hue on Candida Chromogenic Agar medium, a total of 136 yeast strains were isolated from tchapalo and bangui. Molecular identification based on PCR-RFLP of internal transcribed spacers of rDNA (ITS) and sequencing of the ITS and the D1/D2 regions allowed us to assign these isolates to seven species: Candida tropicalis, Candida inconspicua, Candida rugosa, Saccharomyces cerevisiae, Kluyveromyces marxianus, Hanseniaspora guilliermondii, Trichosporon asahii. With the respect to each beverage, six species were found among with four species are regarded as opportunistic pathogens. From these, C. tropicalis, C. inconspicua and K. marxianus were the most commonly encountered. The enzyme activities of the potential pathogens assessed using API ZYM system showed that almost strains had esterase, esterase lipase, valine and cystine arylamidase, alpha chymotrypsin, alkaline phosphatase and naphthol phosphohydrolase activities. The activity of α-glucosidase was found only in C. tropicalis and C. inconspicua strains isolated from tchapalo while β-glucosidase activity was found in all strains from tchapalo and only in C. inconspicua isolated from bangui.     

Clinical and Microbiological Investigation of Fungemia from Four Hospitals in China

In this study, fungemia cases from four tertiary hospitals located in Shanghai and Anhui province in China from March 2012 to December 2013 were enrolled to investigate clinical features, species distribution, antifungal susceptibility and strain relatedness. During the study period, 137 non-duplicate cases and their corresponding isolates were collected. Six different genera of fungi were identified, of which Candida spp. were the most common (126/137, 91.97 %), with C. albicans predominating (48/137, 35.03 %). The non-Candida fungi rate reached 8.03 % (11/137), and Pichia spp. was the most common (5/137, 3.65 %). Compared with C. albicans, non-C. albicans fungi-associated fungemia was more likely in younger (p = 0.004) and male patients (χ ² = 6.2618, p = 0.0123) and patients from ICUs (χ ² = 6.3783, p = 0.0116). Overall, the susceptible/WT rates of common Candida spp. to fluconazole, itraconazole, voriconazole, flucytosine, amphotericin B and caspofungin were 74.63, 92.31, 93.16, 96.58, 100 and 95.69 %, respectively. C. tropicalis and C. guilliermondii had a low susceptibility to fluconazole: 79.95 and 77.78 %, respectively. No isolates were resistant/WT to caspofungin, but C. parapsilosis and C. guilliermondii had high MIC₉₀ values; 1 and 2 mg/L, respectively. In terms of genotyping, MLST was taken for C. glabrata and C. tropicalis, while microsatellite marker analysis was used for C. albicans and C. parapsilosis. C. glabrata was predominantly clone ST7, accounting for 75 %, while the other isolates showed genetic diversity. Considering the increased proportion of non-C. albicans fungi and the presence of endemic clones of C. glabrata, it is essential to undertake additional surveillance of fungemia.
