Abstract
Favolaschia claudopus, a wood-inhabiting basidiomycete of the Mycenaceae family, is considered an invasive species that has recently spread from Oceania to Europe. The CIRM-BRFM 2984 strain of this fungus was originally isolated from a basidiome collected from the fallen limb of a decayed oak tree in Southwest France. The genome sequence of this strain shared characteristics with other Mycenaceae species, including a large genome size and enriched content of protein-coding genes. The genome sequence provided here will facilitate further investigation on the factors that contribute to the successful global dissemination of F. claudopus.

Abstract
BACKGROUND The genus Camillea was created in 1849 from collections made in French Guiana with eight species included. Numerous species assigned to Camillea were subsequently discovered, especially in the forests of the Amazon basin, but new discoveries have not been reported from French Guiana since 1849. Recent fieldwork in French Guiana has begun to fill this gap by identifying five new species, most of which were collected in the vicinity of Saül village. RESULTS Based on macro- and micromorphological study of their stromata, including SEM images of ascospore wall ornamentation, five new species were recognized, including C. cribellum, C. heterostomoides, C. nitida, C. rogersii and C. saulensis. Cultures could be obtained for C. heterostomoides and C. rogersii, and ITS and LSU sequences were obtained for all of the five new species. Camillea heterostoma and its variety microspora were shown to be conspecific. Provisional molecular phylogenetic analyses support the possible reinstatement of Hypoxylon melanaspis, currently regarded as merely an applanate form of C. leprieurii. CONCLUSION The current study is based on a relatively limited fieldwork in its duration and sampling area but was able to substantially increase the number of Camillea species known from French Guiana. This augurs an exceptional and still unknown diversity of the genus in this area and by extension in the adjacent neotropical forests.

Abstract
Fungal biotechnology is set to play a keystone role in the emerging bioeconomy, notably to address pollution issues arising from human activities. Because they preserve biological diversity, Biological Resource Centres are considered as critical infrastructures to support the development of biotechnological solutions. Here, we report the first large-scale phenotyping of more than 1,000 fungal strains with evaluation of their growth and degradation potential towards five industrial, human-designed and recalcitrant compounds, including two synthetic dyes, two lignocellulose-derived compounds and a synthetic plastic polymer. We draw a functional map over the phylogenetic diversity of Basidiomycota and Ascomycota, to guide the selection of fungal taxa to be tested for dedicated biotechnological applications. We evidence a functional diversity at all taxonomic ranks, including between strains of a same species. Beyond demonstrating the tremendous potential of filamentous fungi, our results pave the avenue for further functional exploration to solve the ever-growing issue of ecosystems pollution.

Abstract
White-rot (WR) fungi are pivotal decomposers of dead organic matter in forest ecosystems and typically use a large array of hydrolytic and oxidative enzymes to deconstruct lignocellulose. However, the extent of lignin and cellulose degradation may vary between species and wood type. Here, we combined comparative genomics, transcriptomics and secretome proteomics to identify conserved enzymatic signatures at the onset of wood-decaying activity within the Basidiomycota genus Pycnoporus. We observed a strong conservation in the genome structures and the repertoires of protein-coding genes across the four Pycnoporus species described to date, despite the species having distinct geographic distributions. We further analysed the early response of P. cinnabarinus, P. coccineus and P. sanguineus to diverse (ligno)-cellulosic substrates. We identified a conserved set of enzymes mobilized by the three species for breaking down cellulose, hemicellulose and pectin. The co-occurrence in the exo-proteomes of H2O2-producing enzymes with H2O2-consuming enzymes was a common feature of the three species, although each enzymatic partner displayed independent transcriptional regulation. Finally, cellobiose dehydrogenase-coding genes were systematically co-regulated with at least one AA9 lytic polysaccharide monooxygenase gene, indicative of enzymatic synergy in vivo. This study highlights a conserved core white-rot fungal enzymatic mechanism behind the wood-decaying process.

Abstract
Because they comprise some of the most efficient wood‐decayers, Polyporales fungi impact carbon cycling in forest environment. Despite continuous discoveries on the enzymatic machinery involved in wood decomposition, the vision on their evolutionary adaptation to wood decay and genome diversity remains incomplete. We combined the genome sequence information from 50 Polyporales species, including 26 newly sequenced genomes and sought for genomic and functional adaptations to wood decay through the analysis of genome composition and transcriptome responses to different carbon sources. The genomes of Polyporales from different phylogenetic clades showed poor conservation in macrosynteny, indicative of genome rearrangements. We observed different gene family expansion/contraction histories for plant cell wall degrading enzymes in core polyporoids and phlebioids and captured expansions for genes involved in signalling and regulation in the lineages of white rotters. Furthermore, we identified conserved cupredoxins, thaumatin‐like proteins and lytic polysaccharide monooxygenases with a yet uncharacterized appended module as new candidate players in wood decomposition. Given the current need for enzymatic toolkits dedicated to the transformation of renewable carbon sources, the observed genomic diversity among Polyporales strengthens the relevance of mining Polyporales biodiversity to understand the molecular mechanisms of wood decay.

Abstract
BACKGROUND Plant biomass conversion for green chemistry and bio-energy is a current challenge for a modern sustainable bioeconomy. The complex polyaromatic lignin polymers in raw biomass feedstocks (i.e., agriculture and forestry by-products) are major obstacles for biomass conversions. White-rot fungi are wood decayers able to degrade all polymers from lignocellulosic biomass including cellulose, hemicelluloses, and lignin. The white-rot fungus Polyporus brumalis efficiently breaks down lignin and is regarded as having a high potential for the initial treatment of plant biomass in its conversion to bio-energy. Here, we describe the extraordinary ability of P. brumalis for lignin degradation using its enzymatic arsenal to break down wheat straw, a lignocellulosic substrate that is considered as a biomass feedstock worldwide. RESULTS We performed integrative multi-omics analyses by combining data from the fungal genome, transcriptomes, and secretomes. We found that the fungus possessed an unexpectedly large set of genes coding for Class II peroxidases involved in lignin degradation (19 genes) and GMC oxidoreductases/dehydrogenases involved in generating the hydrogen peroxide required for lignin peroxidase activity and promoting redox cycling of the fungal enzymes involved in oxidative cleavage of lignocellulose polymers (36 genes). The examination of interrelated multi-omics patterns revealed that eleven Class II Peroxidases were secreted by the fungus during fermentation and eight of them where tightly co-regulated with redox cycling enzymatic partners. CONCLUSION As a peculiar feature of P. brumalis, we observed gene family extension, up-regulation and secretion of an abundant set of versatile peroxidases and manganese peroxidases, compared with other Polyporales species. The orchestrated secretion of an abundant set of these delignifying enzymes and redox cycling enzymatic partners could contribute to the delignification capabilities of the fungus. Our findings highlight the diversity of wood decay mechanisms present in Polyporales and the potentiality of further exploring this taxonomic order for enzymatic functions of biotechnological interest.

Abstract
We describe two serious Trametes polyzona pulmonary infections, which occurred in Réunion Island, in critically ill patients. The identification was performed using sequencing of the internal transcribed spacer region of ribosomal DNA and D1/D2 region of 28S rDNA. In one case, the significance of T. polyzona in the pathological process was certain, proven by histopathological evidence of fungal lung infection. T. polyzona, an emerging filamentous basidiomycete, prevalent in tropical areas, has not been described so far in human infections.

Abstract
Myeloablative treatment preceding hematopoietic stem cell (HSC) and progenitor cell (HS/PC) transplantation results in severe myeloid cytopenia and susceptibility to infections in the lag period before hematopoietic recovery. We have previously shown that macrophage colony-stimulating factor (CSF-1; M-CSF) directly instructed myeloid commitment in HSCs. In this study, we tested whether this effect had therapeutic benefit in improving protection against pathogens after HS/PC transplantation. M-CSF treatment resulted in an increased production of mature myeloid donor cells and an increased survival of recipient mice infected with lethal doses of clinically relevant opportunistic pathogens, namely the bacteria Pseudomonas aeruginosa and the fungus Aspergillus fumigatus M-CSF treatment during engraftment or after infection efficiently protected from these pathogens as early as 3 days after transplantation and was effective as a single dose. It was more efficient than granulocyte CSF (G-CSF), a common treatment of severe neutropenia, which showed no protective effect under the tested conditions. M-CSF treatment showed no adverse effect on long-term lineage contribution or stem cell activity and, unlike G-CSF, did not impede recovery of HS/PCs, thrombocyte numbers, or glucose metabolism. These results encourage potential clinical applications of M-CSF to prevent severe infections after HS/PC transplantation.

Abstract
Polyporales are extensively studied wood-decaying fungi with applications in white and green biotechnologies and in medicinal chemistry. We developed an open-access, user-friendly, bioinformatics tool named FunGene-DB (http://www.fungene-db.org). The goal was to facilitate the molecular authentication of Polyporales strains and fruit-bodies, otherwise subjected to morphological studies. This tool includes a curated database that contains ITS1-5.8S-ITS2 rDNA genes screened through a semi-automated pipeline from the International Nucleotide Sequence Database (INSD), and the similarity search BLASTn program. Today, the web-accessible database compiles 2379 accepted sequences, among which 386 were selected as reference sequences (most often fully identified ITS sequences for which a voucher, strain or specimen, has been deposited in a public-access collection). The restriction of the database to one reference sequence per species (or per clade for species complex) allowed most often unequivocal analysis. We conclude that FunGene-DB is a promising tool for molecular authentication of Polyporales. It should be especially useful for scientists who are not expert mycologists but who need to check the identity of strains (e.g. for culture collections, for applied microbiology).

Abstract
Fusarium verticillioides secretes enzymes (secretome), some of which might be potentially useful for saccharification of lignocellulosic biomass since supplementation of commercial cellulases from Trichoderma reesei with the F. verticillioides secretome improved the enzymatic release of glucose, xylose and arabinose from wheat straw by 24%, 88% and 68%, respectively. Determination of enzymatic activities revealed a broad range of hemicellulases and pectinases poorly represented in commercial cocktails. Proteomics approaches identified 57 proteins potentially involved in lignocellulose breakdown among a total of 166 secreted proteins. This analysis highlighted the presence of carbohydrate-active enzymes (CAZymes) targeting pectin (from glycoside hydrolase families GH5, GH27, GH28, GH43, GH51, GH54, GH62, GH88 and GH93, polysaccharide lyase family PL4 and carbohydrate esterase family CE8) and hemicelluloses (from glycoside hydrolase families GH3, GH10, GH11, GH30, GH39, GH43 and GH67). These data provide a first step towards the identification of candidates to supplement T. reesei enzyme preparations for lignocellulose hydrolysis.

Abstract
BACKGROUND Filamentous fungi are potent biomass degraders due to their ability to thrive in ligno(hemi)cellulose-rich environments. During the last decade, fungal genome sequencing initiatives have yielded abundant information on the genes that are putatively involved in lignocellulose degradation. At present, additional experimental studies are essential to provide insights into the fungal secreted enzymatic pools involved in lignocellulose degradation. RESULTS In this study, we performed a wide analysis of 20 filamentous fungi for which genomic data are available to investigate their biomass-hydrolysis potential. A comparison of fungal genomes and secretomes using enzyme activity profiling revealed discrepancies in carbohydrate active enzymes (CAZymes) sets dedicated to plant cell wall. Investigation of the contribution made by each secretome to the saccharification of wheat straw demonstrated that most of them individually supplemented the industrial Trichoderma reesei CL847 enzymatic cocktail. Unexpectedly, the most striking effect was obtained with the phytopathogen Ustilago maydis that improved the release of total sugars by 57% and of glucose by 22%. Proteomic analyses of the best-performing secretomes indicated a specific enzymatic mechanism of U. maydis that is likely to involve oxido-reductases and hemicellulases. CONCLUSION This study provides insight into the lignocellulose-degradation mechanisms by filamentous fungi and allows for the identification of a number of enzymes that are potentially useful to further improve the industrial lignocellulose bioconversion process.

Abstract
The genus Pycnoporus forms a group of four species known especially for producing high redox potential laccases suitable for white biotechnology. A sample of 36 Pycnoporus strains originating from different geographical areas was studied to seek informative molecular markers for the typing of new strains in laboratory culture conditions and to analyse the phylogeographic relationships in this cosmopolitan group. ITS1-5.8S-ITS2 ribosomal DNA and partial regions of β-tubulin and laccase lac3-1 gene were sequenced. Phylogenetic trees inferred from these sequences clearly differentiated the group of Pycnoporus cinnabarinus strains from the group of Pycnoporus puniceus strains into strongly supported clades (100% bootstrap value). Molecular clustering based on lac 3-1 sequences enabled the distribution of Pycnoporus sanguineus and Pycnoporus coccineus through four distinct, well supported clades and sub-clades. A neotropical sub-clade, grouping the P. sanguineus strains from French Guiana and Venezuela, corresponded to P. sanguineus sensu stricto. A paleotropical sub-clade, clustering the strains from Madagascar, Vietnam and New Caledonia, was defined as Pycnoporus cf. sanguineus. The Australian clade corresponded to P. coccineus sensu stricto. The Eastern Asian region clade, clustering the strains from China and Japan, formed a P. coccineus-like group. Laccase gene (lac 3-1) analysis within the Pycnoporus species can highlight enzyme functional diversity associated with biogeographical origin.

Abstract
The Pycnoporus fungi are white-rot basidiomycetes listed as food- and cosmetic-grade microorganisms. Three high redox potential laccases from Pycnoporus coccineus and Pycnoporus sanguineus were tested and compared, with the commercial Suberase® as reference, for their ability to synthesise natural active oligomers from rutin (quercetin-3-rutinoside, one of the best-known naturally occurring flavonoid glycosides). The aim of this work was to develop a process with technical parameters (solvent, temperature, reaction time and raw materials) that were easy to scale up for industrial production and compatible with cosmetic and pharmaceutical formulation guidelines. The aqueous mixture of glycerol/ethanol/buffer described in this study met this requirement and allowed the solubilisation of rutin and its oxidative bioconversion into oligomers. The four flavonoid oligomer mixtures synthesised using laccases as catalysts were analysed by high performance liquid chromatography-diode array detection-negative electrospray ionisation-multistage mass spectrometry. Their chromatographic elution profiles were compared and 16 compounds were characterised and identified as dimers and trimers of rutin. The oligorutins were different in Suberase® and Pycnoporus laccase reaction mixtures. They were evaluated for their antioxidant, anti-inflammatory and anti-ageing activities on specific enzymatic targets such as cyclooxygenase (COX-2) and human matrix metalloproteinase 3 (MMP-3). Expressed in terms of IC(50), the flavonoid oligomers displayed a 2.5- to 3-fold higher superoxide scavenging activity than monomeric rutin. Pycnoporus laccase and Suberase® oligorutins led to an inhibition of COX-2 of about 35% and 70%, respectively, while monomeric rutin showed a near-negligible inhibition effect, less than about 10%. The best results on MMP-3 activity were obtained with rutin oligomers from P. sanguineus IMB W006-2 laccase and Suberase® with about 70-75% inhibition.

Abstract
The in vitro susceptibilities of Cryptococcus neoformans isolates from consecutive human immunodeficiency virus-positive and -negative patients to the antifungal agents fluconazole, amphotericin B, and flucytosine were determined by different techniques, including the CLSI method, Etest, and broth microdilution in yeast nitrogen base (YNB) medium, during a multicenter prospective study in France. The relationship between the in vitro data and the clinical outcome 2 weeks after the initiation of antifungal therapy was assessed. In addition, the correlation between the strain serotype and the in vitro activities of the antifungals was determined, and the susceptibility results obtained with the different techniques were also compared. Thirty-seven patients received a combination of amphotericin B with flucytosine as first-line therapy, 22 were treated with amphotericin B alone, and 15 received fluconazole alone. Whatever the antifungal tested, there was no trend toward higher MICs for strains isolated from patients who failed to respond to a given therapy compared to those from patients who did not with either the CLSI method, Etest, or broth microdilution in YNB medium. The MICs obtained by the CLSI or Etest method were significantly lower for serotype D strains than for serotype A strains for both fluconazole and amphotericin B, while flucytosine MICs were not different according to serotype. These findings suggest that the in vitro antifungal susceptibility of C. neoformans, as determined with the techniques used, is not able to predict the early clinical outcome in patients with cryptococcosis.

Abstract
Seventy-seven crude extracts from leaves and stem barks of 15 Gabonese plants used in traditional medicine were evaluated for their cytotoxic, antileishmanial and antifungal activities. Most of the extracts exhibited cytotoxic activities toward human monocytes, and most particularly the hydromethanolic 50% (v/v) fraction of Ganophyllum giganteum leaves (IC(50)=1.3 microg/ml) as well as the methanolic extracts of Polyalthia suaveolens, Dioscorea preussii, Augouardia letestui leaves and Cola lizae stem barks (IC(50)<5 microg/ml). The methanolic extract of Polyalthia suaveolens displayed a strong antiproliferative activity against the promastigote form of Leishmania infantum parasites and presented a good antifungal activity on all the tested strains (IC(50)<1mg/ml). This extract was divided into six fractions: fraction F6 demonstrated a cytotoxic activity stronger than those of the crude extract (IC(50)=0.6 microg/ml), fractions F4 and F5 were devoid of cytotoxicity (IC(50)>100 microg/ml) and displayed interesting antileishmanial activity against the intracellular amastigote form of the parasite (IC(50)=5.6 and 12.4 microg/ml), respectively. However, the antifungal activity observed for the crude extract could not be recovered in the corresponding fractions.

Abstract
We report on five clinical isolates routinely identified as Candida lusitaniae that the ID 32C system was unable to discriminate from the closely related species Candida pulcherrima. When additional tests did not allow accurate identification, the less usual mating type test identified all of them as Clavispora lusitaniae. Mating type testing appears to be a valuable tool for assessing the true incidence of this emerging non-albicans Candida species.

Abstract
The antifungal activity of a crude steroidal glycoside extract from Yucca gloriosa flowers, named alexin, was investigated in vitro against a panel of human pathogenic fungi, yeasts as well as dermatophytes and filamentous species. The minimal inhibitory concentration (MIC) was determined by an agar dilution method. Alexin had a broad spectrum of antifungal activity, found to reside entirely in the spirostanoid fraction. The major tigogenyl glycosides, yuccaloeside B and yuccaloeside C, exhibited MICs between 0.39 and 6.25 microg[sol ]mL for all the tested yeast strains except for two (C. lusitaniae and C. kefyr). They were also active against several clinical Candida isolates known to be resistant to the usual antifungal agents. The MICs for the dermatophytes were between 0.78 and 12.5 microg[sol ]mL. The most sensitive filamentous species was A. fumigatus (MIC = 1.56 microg[sol ]mL). For most of the strains, the MICs of both glycosides were similar to those of the reference antifungal agent.

Abstract
OBJECTIVES The aim of the present study was to expand the MIC database for Candida lusitaniae in order to further determine its antifungal susceptibility pattern. METHODS The activities of amphotericin B, fluconazole, itraconazole, voriconazole and flucytosine were determined in vitro against 80 clinical isolates of C. lusitaniae. A set of 59 clinical isolates of Candida albicans and of 51 isolates of Candida glabrata was included to compare the susceptibilities to amphotericin B. The MICs were determined by Etest with RPMI 1640 agar, and with both this medium and antibiotic medium 3 (AM3) agar for testing of amphotericin B. RESULTS All isolates were highly susceptible to fluconazole. The susceptibility to itraconazole was good; only 4% of isolates had dose-dependent susceptibility (MICs 0.25-0.5 mg/L). Voriconazole was very active in vitro (100% of isolates were inhibited at < or =0.094 mg/L). Flucytosine MICs ranged widely (0.004->32 mg/L). The set included 19% of flucytosine-resistant isolates. For amphotericin B, 100% of isolates were inhibited at < or =0.75 mg/L (MIC(50) 0.047 mg/L; MIC(90) 0.19 mg/L) and at < or =4 mg/L (MIC(50) 0.25 mg/L; MIC(90) 0.75 mg/L) on RPMI and on AM3, respectively. A single isolate was categorized as resistant to amphotericin B (MIC 0.75 and 4 mg/L on RPMI and on AM3, respectively). Amphotericin B thus appeared very active in vitro against C. lusitaniae. Whatever the test medium, the level of susceptibility of C. lusitaniae to amphotericin B did not differ much from those of C. albicans and C. glabrata. CONCLUSION C. lusitaniae appears to be susceptible to amphotericin B, azole antifungal agents, and, to a lesser extent, flucytosine.

Abstract
Candida lusitaniae is an emerging opportunistic pathogen which exhibits an unusual antifungal susceptibility pattern. We describe a case of fatal renal infection due to C. lusitaniae in a very low birth weight neonate who was treated with short courses of fluconazole given alternately with amphotericin B. A colony morphology switching was detected on the standard primary culture medium by changes in colony size. Switching was shown to affect deeply the susceptibility to amphotericin B. Afterwards, the switched phenotype developed a cross resistance to fluconazole and itraconazole. Several issues raised by this case are discussed in the light of an extensive review of the literature. Our observations point out the importance of both the detection of colony morphology switching and the close monitoring of antifungal susceptibility in the management of infections due to C. lusitaniae. A judicious therapeutic strategy should prevent the acquisition of multidrug resistance during antifungal therapy.

Abstract
The sterol and fatty acid compositions of four amphotericin B-resistant and of two amphotericin B-susceptible Candida lusitaniae clinical isolates were determined. A flow cytofluorometric susceptibility test (FCST) with a membrane potential-sensitive cationic dye was used as a complement to the conventional method for selecting the isolates. Compared to susceptible isolates, resistant ones showed a greatly reduced ergosterol content and changes in sterol composition, consistent with a defect in Delta8-->7 isomerase. Within each group, no correlation between the sterol or fatty acid pattern or composition and both the degree of in vitro susceptibility and FCST MIC was found.

Abstract
The in vitro mating ability of Candida lusitaniae (teleomorph Clavispora lusitaniae) clinical isolates has been investigated. Studying the effects of culture conditions, we showed that ammonium ion depletion in the medium is a major trigger of the sexual cycle. Moreover, a solid support is required for mating, suggesting a role for adhesion factors in addition to the mating type gene recognition function. Monitoring of mating and meiosis efficiency with auxotrophic strains showed great variations in ascospore yields, which appeared to be strain and temperature dependent, with an optimal range of 18 to 28 degrees C. The morphogenetic events taking place from mating to ascospore release were studied by scanning and electron microscopy, and the ultrastructure of the conjugation canal, through which intercellular nuclear exchanges occur, was revealed. Labeling experiments with a lectin-fluorochrome system revealed that the nuclear transfer was predominantly polarized, thus allowing a distinction between the nucleus donor and the nucleus acceptor strains. The direction of the transfer depended on the strain combination used, rather than on the genotypes of the strains, and did not appear to be controlled by the mating type genes. Finally, we demonstrated that all of the 76 clinical isolates used in this study were able to reproduce sexually when mated with an opposite mating type strain, and we identified a 1:1 MATa/MATalpha ratio in the collection. These results support the idea that there is no anamorph state in C. lusitaniae. Accordingly, the mating type test, which is easy to use and can usually be completed within 48 h, is a reliable alternative identification system for C. lusitaniae.

Abstract
Both intrinsic and acquired resistance to amphotericin B have been documented for Candida lusitaniae. Amphotericin B remains the drug of choice for many critical fungal infections, and the detection of resistance is essential to monitor treatment effectively. The limitations of the National Committee for Clinical Laboratory Standards (NCCLS) reference methodology for detection of amphotericin B resistance are well documented, and several alternative methods have been proposed. Etest assays with RPMI and antibiotic medium 3 (AM3) agar were compared to the NCCLS M27-A broth macrodilution method using AM3 for amphotericin B resistance testing with 49 clinical isolates of C. lusitaniae. The panel included nine isolates with known or presumed resistance to amphotericin B on the basis of in vivo and/or in vitro data. The distribution of amphotericin B MICs by Etest with RPMI ranged from 0. 032 to 16 microg/ml and was bimodal. All of the putatively resistant isolates were inhibited by amphotericin B at >/=0.38 microg/ml and could be categorized as resistant using this breakpoint. Etest with AM3 yielded a broader amphotericin B MIC range (0.047 to 32 microg/ml), and there were six putatively resistant isolates for which MICs were >1 microg/ml. The separation of putatively susceptible and resistant isolates was less obvious. Broth macrodilution with AM3 generated a unimodal distribution of MICs (ranging from 0.032 to 2 microg/ml) and failed to discriminate most of the putatively resistant isolates at both 24 and 48 h. Etest using RPMI and, to a lesser extent, using AM3 provided better discrimination between amphotericin B-resistant and -susceptible isolates of C. lusitaniae.

Abstract
The ability of the API Candida system (bioMérieux, France) to identify Candida lusitaniae isolates was evaluated in comparison to the Auxacolor and ID 32C systems using 52 clinical isolates previously identified on the basis of their morphology and their biochemical reactions in the Auxacolor and ID 32C systems. The API Candida system failed to definitively identify most of the strains tested within 24 h. No beta-maltosidase activity was detected in 28 strains, and supplementary tests were required to discriminate Candida lusitaniae, Candida famata and Candida guilliermondii. The API Candida system is not suitable for identification of Candida lusitaniae. In comparison, the Auxacolor system is easy to use and interpret, allowing rapid identification of this species; however, the ID 32C system is required for identification of atypical strains.

Abstract
The E test was compared to the reference NCCLS broth macrodilution method for susceptibility testing of Candida (Torulopsis) glabrata. The MICs of amphotericin B, flucytosine, fluconazole and itraconazole were determined using the appropriate culture media (RPMI 1640 agar with 2% glucose, Casitone agar or Antibiotic Medium 3 agar) according to the drug tested. Agreement between the two methods was within plus/minus two dilutions for 77-100% of test results, according to the drug/medium combination. The study revealed problems in determining the MICs of azoles using the E test, and confirmed the suitability of Casitone agar for susceptibility testing of fluconazole even if results were read within 24 h.

Abstract
A flow cytofluorometric susceptibility test (FCST) was used for rapid determination of the susceptibility of Candida lusitaniae isolates to amphotericin B. The test is based on the decrease in fluorescence intensity of cells stained with 3,3'-dipentyloxacarbocyanine iodide (DiOC5(3)), a membrane potential-sensitive cationic dye, after drug treatment. A total of 58 C. lusitaniae clinical isolates including strains known to be amphotericin B-resistant on the basis of in-vivo and/or in-vitro data were tested. MICs were determined concurrently by the NCCLS broth macrodilution method and the Etest, both with antibiotic medium 3. Regression analysis demonstrated that the data from the FCST and the Etest were better correlated (r = 0.93, n = 59, P < 0.001) than those from the FCST and the NCCLS method (r = 0.63, n = 59, P < 0.001). The FCST readily identified a series of putatively susceptible and resistant isolates. Our study points out the advantages of the flow cytometry approach in antifungal susceptibility testing of yeasts, since speed remains a major problem in conventional tests.

Abstract
alpha-Hederin, a saponin isolated from Hedera helix (L.) (Araliaceae), was tested on Candida albicans ultrastructure. The concentrations used were 6.25, 12.5, and 25 micrograms ml-1 for an exposure time of 24 h. Transmission electron microscopy observations indicated that compared with untreated control yeasts, alpha-hederin induced modifications of cellular contents and alterations of cell envelope with degradation and death of the yeasts. The impact of alpha-hederin on the biomembranes and in particular on the plasmalemma is discussed. The antifungal activity of alpha-hederin was confirmed, as was the minimal inhibitory concentration (25 micrograms ml-1).

Abstract
A rapid-flow cytofluorometric susceptibility test for in vitro amphotericin B testing of yeasts was evaluated and compared to the National Committee for Clinical Laboratory Standards (NCCLS) M27-T reference broth macrodilution method. The flow cytofluorometric method is based on the detection of decreased green fluorescence intensity of cells stained with DiOC5(3), a membrane potential-sensitive cationic dye, after drug treatment. Testing was performed on 134 clinical isolates (Candida spp. and Torulopsis glabrata). From the dose-response curve obtained for each isolate, three endpoints were calculated by computer analysis (the concentrations at which the fluorescence intensity was reduced by 50, 80, and 90%, i.e., 50% inhibitory concentration [IC50], IC80, and IC90, respectively). A regression analysis correlating these endpoints with the M27-T MICs showed that the best agreement was obtained with IC80. The flow cytofluorometric method showed good reproducibility with control strains. These initial results suggest that the flow cytofluorometric method is a valid alternative to the NCCLS reference method.

Abstract
The antifungal susceptibility of 35 Candida lusitaniae isolates was determined in vitro by the National Committee for Clinical Laboratory Standards (NCCLS) M27-P macrodilution methodology. All the isolates were susceptible to ketoconazole, itraconazole and fluconazole. Of the 35 isolates, eight (23%) were resistant to flucytosine. For amphotericin B, M27-P yielded a narrow range of MICs (0.06-0.5 mg/L). We therefore investigated the activity of this drug by reading MICs at 72 h and by using alternative media, namely casitone complex medium (CCM) and antibiotic medium 3 (M-3). Reading at 72 h did not generate reproducible results. CCM and M-3 provided better discrimination between the isolates but did not change the rank order of the MICs. We thus concluded that all the isolates were susceptible to amphotericin B. We also conducted an evaluation with the Etest method according to the manufacturer's instructions with RPMI 1640 agar, CCM and the alternative semi-synthetic medium (SSM). For RPMI 1640, agreements +/-2 dilutions were 58% for amphotericin B, 92% for flucytosine, 57% for ketoconazole, 92% for fluconazole and 74% for itraconazole. CCM did not improve the agreement rates between the two methods but it led to better growth of all the isolates. The suitability of SSM was pointed out with itraconazole. The poor agreement rates for amphotericin B and ketoconazole call for further evaluation of the Etest method to assess several drug-organism combinations.

Abstract
Several indole alkaloids were tested by the agar dilution technique on a panel of human pathogenic fungi, yeasts, and dermatophytes. Our results indicate that the most active compounds possess a beta-carboline skeleton and that the presence of a 3-4 double bond enhances the activity. Our results also show that antifungal activities are not linked to the cytotoxic, antimicrobial or antiparasitic properties.

Abstract
The antifungal activity of triterpenoid saponins, with hederagenin or oleanolic acid as aglycone, was investigated in vitro by the agar dilution method. Monodesmosidic hederagenin derivatives were shown to exhibit a broad spectrum of activity against yeast as well as dermatophyte species. alpha-Hederin was the most active compound, and Candida glabrata was the most susceptible strain. The structure-activity relationships are discussed.

Abstract
Microproteins with proteinase inhibitory activity, 28 to 30 amino acids long, with 3 disulfide bridges have been isolated from Ecballium elaterium seeds. A peptide (EETI II) was isolated and behaved as a powerful trypsin inhibitor (Kd = 10(-11) to 10(-12) M). It was sequenced, chemically synthesized and the 3-D structure determined by 2-D 1H NMR. The information gained in the process enabled us to synthesize modified derivatives with inhibitory activity towards pancreatic elastase, chymotrypsin and human leucocyte elastase (Kd = 10(-7) to 10(-9) respectively). The most striking characteristic that appeared during the synthetic approach was the unfailing ability of the 28 amino acid peptides to refold and correctly close the 3 disulfide bridges, giving in each case an active compound. These disulfide bridges are assembled in a particular knotted structure, shared by few other bioactive peptides and called the 'knottin' structure. Molecular modeling of the peptide and a comparison with the other active molecules with similar topology allowed the synthesis of a chimaeric peptide, bearing 1 active site against a seryl-protease (trypsin), and 1 against a metallo-protease (carboxypeptidase A). The bis-headed peptide was able to inhibit both enzymes separately and concomitantly.

Abstract
Seven microproteins analogous to Ecballium elaterium Trypsin Inhibitor II. were synthesized. The study of their inhibiting power showed a change in selectivity from trypsin to elastase for 5 of the compounds and to alpha-chymotrypsin for another one. A striking characteristic that appeared during this synthetic approach was the ability of the 28 amino acid peptides to refold and close correctly the 3 disulfide bridges, giving in each case an active compound.

Abstract
Several protease inhibitors were found in the seeds of a Cucurbitacea, Ecballium elaterium, and were separated from one another by affinity and molecular sieve chromatography. Three main trypsin isoinhibitors were purified by ion-exchange chromatography and the sequence of the major one, EETI II, was elucidated and compared with other inhibitors of the squash family. It is a peptide of M.W. 3020 of strong inhibitory activity (Ka = 8 x 10(11) M-1) against trypsin, showing high Gly content, six half-cystine residues, but devoid of histidine, threonine, tryptophan, and tyrosine residues.

Abstract
Chlorpromazine inhibits by about 60% the lipid peroxidation stimulated by Fe2+/ascorbate in liposomes and the lipid peroxidation stimulated by cumene hydroperoxide in microsomes. Under the same conditions, two new synthetic derivatives of chlorpromazine, i.e., a N-benzoyloxymethylchlorpromazine and a N-pivaloyloxymethylchlorpromazine, induce no more than a 20% inhibition. On the other hand, when the different chlorpromazines are entrapped in liposomes and subsequently irradiated with near-UV light, they act as photosensitizing agents giving rise to lipid peroxidation. The latter is quite extensive in the presence of chlorpromazine or N-pivaloyloxymethylchlorpromazine, whereas it is drastically lower in the presence of N-benzoyloxymethylchlopromazine. The N-benzoyloxymethylchlorpromazine molecule, despite its low photodynamic effect, retains its neuroleptic properties. The possible mechanisms of the antioxidant and prooxidant actions of these compounds are discussed.
