Introduction: The secretion of hydrolytic enzymes is a factor facilitating pathogenic fungi invasion into the tissues. Purpose: To assess hydrolytic activity and biotypes of Candida strains isolated from samples collected from the surfaces of mobile phones and the hands of their owners. Materials and methods: The study included 175 mobile telephones and hands. The API ZYM test was used to assess enzymatic activity; biotyping was performed according to Williamson’s classification. Results: Among the strains isolated from hand surfaces, the highest activity was shown for C. albicans (acid phosphatase, esterase), C. glabrata (leucine arylamidase, acid phosphatase, esterase), and C. krusei (acid phosphatase). Of the strains isolated from phone surfaces, the highest activity was shown for C. albicans (leucine arylamidase, acid phosphatase), C. glabrata (esterase, leucine arylamidase, esterase lipase), and C. krusei (acid phosphatase). Biotypes G, B and F were dominant for all types of fungi, both for strains isolated from phones and hand surfaces. Additionally, biotype A was dominant for C. krusei. Conclusions: C. albicans, C. glabrata, and C. krusei showed activity for all hydrolytic enzymes. The strongest correlation between the hydrolytic activity of fungi isolated from hand and phone surfaces was shown for C. albicans.

Opis:
The incidence of Candida spp. infections has increased in recent years due to the widespread use of broad-spectrum antibiotics and the growing numbers of immunocompromised individuals. Despite the predominance of Candida albicans, non-albicans Candida species, such as Candida glabrata, Candida tropicalis, Candida guilliermondii, Candida dubliniensis, Candida parapsilosis, and Candida krusei are emerging as both, colonizers and pathogens, that can cause superficial and systemic infections. Currently, there are various methods for identifying yeasts from clinical samples. Conventional methods for identification of Candida species are based on morphological and physiological attributes. Although phenotypic identification methods are cost effective and practical procedures for routine discrimination of isolates in the clinical microbiology laboratory, the accurate identification of all isolates. Moreover, given the variability in the phenotypic characteristics and other irregularities in the taxonomy of the genus Candida, identification based on traditional methods has become less reliable. Important progress has been made with various studies on the phenotypic characteristics of these species using commercially available identification systems. The aim of this review is to summarize the methods available for identification of Candida species. The first part of the article presents the characteristics of phenotypic methods and quick identification techniques, including systems based on the use of chromogenic media.

Opis:
A rapid and accurate identification of the Candida is crucial for clinical treatment of local and systemic candidiasis. Premature diagnosis of invasive fungal infections is problematic because most clinical signs are non-specific and cultures are often negative or become positive too late for the initiation of effective antifungal therapy. Therefore, studies have been performed to improve molecular techniques for the diagnosis of candidiasis. Today, molecular strategies, such as PCR and non-PCR based methods are used to complement conventional laboratory approach. They provide accurate results in much short time of 1.5–3 h. Given the high accuracy and time saving with molecular typing techniques it is likely that most of these methods could improve routine clinical laboratory identification of Candida yeast species. However, further studies are needed for standardization of such procedures. This article presents an overview and discussion on molecular identification methods in the context of their application for the diagnosis of Candida fungi. Particular attention has been focused on the advantages and limitations of the indicated methods and the possibilities of their implementation for routine use in clinical laboratories.

Opis:
It is imperative that pathogenic agents are identified accurately to the species level. The implementation of automatic systems for the identification of Candida yeasts is associated with a large number of tests performed by a given unit, which certainly has a further impact on the price of a single test and the use of devices. Hence, automatic systems are widely used in high-throughput laboratories, e.g. in commercial laboratories with a wide range of activities. Veterinary clinics with their own microbiological unit usually use classical identification methods or semi-automatic systems based on biochemical tests for independent interpretation of the results. Nevertheless, the increased number of invasive procedures, inherent in prolonged hospitalization of animals, and the use of broad-spectrum antibiotic therapy, leads to the conclusion that using automatic fungal identification systems in veterinary laboratories is only a matter of time, and their implementation may leave the classical techniques obsolete. This article provides an overview and discussion of automatic systems as well as new, rapid methods of diagnosing Candida fungi. Particular attention has been focused on Vitek YBC, Vitek 2 ID-YST, Abbot Quantum II, and Microbial ID systems.

Opis:
Formation of fungal biofilms in patients with implanted biomedical prosthesis constitutes very serious clinical problems. The biofilm can lead to dysfunction of implanted material and can be a reservoir for chronic and systemic infections. Numerous investigations demonstrated differences in quantity and structure of biofilms that had been formed by various species of fungi belonged to Candida genus. Stages of biofilm formations had been examined carefully in in vitro conditions. Biofilm formation begin with adhesion of fungi to the surface, microcolonies are formed subsequently. At the end of the process, extracellular material is excreted, and its formula, that is various in different fungi Candida species, contribute to its resistance to antifungal drugs. Farnesol and tyrosol are two quorum-sensing molecules. They are acting inversely, regulating formation of „germ tubes” and influencing morphogenetic conversion between yeast and filamentous forms, which plays a very important role in pathogenicity and formation of biofilm. Drug resistance of fungi from Candida has been shown to create a very important clinical problem. Many experiments in vitro confirm significantly lower activity of antifungal drugs toward Candida biofilm than toward Candida, in the form of planctonic cells. Surprisingly, some non-steroidal anti-inflammatory drugs can inhibit biofilm formation.

Opis:
Introduction. Among the microorganisms colonizing the oral cavity ontocenosis, an important role is played by fungi: mainly yeast-like fungi of the Candida genus, and especially by the species C. albicans. Objective. The aim of this study was to evaluate the frequency of oral colonization by Candida species in healthy individuals of different age groups, and to identify the species of the isolates. Materials and method. The fungi were isolated from the oral cavities of 654 healthy individuals of both genders, representing different age groups, and the species of the isolates were determined. Initial identification of the yeast-like fungi was made based on the macroscopic appearance of the colonies on Sabouraud’s medium, and the growth of coloured colonies on ChromAgar Candida medium. API 20 C AUX microtest (bioMerieux) was used to identify the most frequently found species of Candida spp. Results. The frequency of Candida isolation from the oral cavity ontocenosis in healthy individuals of different age groups was assessed as 30.6%. The oral cavity ontocenosis was colonized mainly by the yeast-like fungi of C. albicans species: they were found in 24.5% of the tested population, while the frequency of oral cavity colonization by non-albicans Candida spp. was 6.1%. Seven species of non-albicans Candida spp. were identified: C. glabrata, C. inconspicua, C. famata, C. tropicalis, C. parapsilosis, C. lusitaniae, and C. kefyr. Conclusions. In the Polish population, 30.6% of the oral cavity ontocenosis is colonized by Candida yeast-like fungi, while C. albicans is the fungus that colonizes oral cavity ontocenosis most frequently. The frequency of oral cavity ontocenosis colonization with Candida spp (including C. albicans) increases with age.

Opis:
Early detection and correct diagnosis of fungal infection is important for further therapy and prophylaxis. Currently, there are a number of proposals related to rapid diagnostic tests. To those we can include chromogenic media, such as CHROMagar® Candida (GRASO). This medium has been developed to differentiate four species of genus Candida. Its use in laboratory has opened up possibilities for growing not only the genus Candida, but also other fungi. The study suggests that medium CHROMagar® Candida can provide an excellent pre-test, or be used as complementary to biochemical tests. Establishing a full template of colours would enable more efficient and fuller use of the medium properties, especially in the discrimination of the teleomorphic form from anamorphic.

Increasing use of elctromagnetic fields (EF) in the treatment of various diseases may have potential impacts on fungi - possible aetiological factors of concomitant mycoses. The aim of this study was to investigate the effects of EF on miconazole susceptibility among fungi of the genus Candida showing confirmed pathogenicity in humans. Fifteen Candida strains obtained from patients were used and their susceptibility to miconazole was determined by diffusion in agar gel. Antifungal activity of miconazole was assessed as minimal inhibitory concentration (MIC) which was calculated for Candida strains not exposed to EF (control) and EF-exposed (3 experiments). In the majority of cases the susceptibility of Candida species to miconazole decreased (higher MICs) after the first week of EF exposure, regardless of the EF's parameters. This was followed by an increase in susceptibility (lower MICs) after the second week of exposure to EF of 2 mT intensity and frequency 3 Hz (experiment I) and an EF of 9 mT intensity and 12.5 Hz frequency (experiment II) relative to control. An increase in susceptibility (lower MICs) was observed in the second week of exposure, whatever the parameters of the EF. The application of low intensity, low frequency EF for a period of at least two weeks may be beneficial in the treatment of mycoses caused by pathogenic fungi of Candida genus.

Opis:
We have studied the capability of dissociation of 22 L-form aminoacids by 27 strains of fungi belonging to species: Candida, Cryptococcus, Geotrichum, Rhodotorula, Saccharomyces, Trichosporon. Fungal strains were cultured on agar medium with phenyl red and studied aminoacid. Disamination of an aminoacid by a fungus resulted in alkalisation of the medium and change of its colour from yellow to pink. Strains from genus Trichosporon and Geotrichum decomposed the most aminoacids (15-16), while fungi from genus Candida decomposed less aminoacid (1-8). Strains form species Candida famata, C. kefyr, C. lambica. C. rugosa, C. neoformans, R. mucilaginosa and S. cerevisiae did not show any ability to desaminate any of the 22 aminoacids used in the study. Aminoacids most frequently disaminated by the studied strains of fungi included acidic aliphatic aminoacids and their amides: L-aspartic acid, L-asparagine, L-glutaminic acid, L-glutamine and neutral aliphatic aminoacids: L-glycin, L-alanine, L-serine. Aromatic and sulphur aminoacids (L-cysteine, L-cystine) were not decomposed by the studied fungal strains.

The human body is composed of 1014 cells, of which only 10% of them belong to the human host itself: the remaining 90% are microorganisms. Commensal microorganisms are necessary for the proper functioning of the human body and covers an area that could potentially become sites of adhesion of pathogenic microorganisms, it thus represents a form of competition for potential pathogens. The coexistence of fungi and bacteria in cases of systemic infections is a significant diagnostic and therapeutic problem, and the human immune system reacts differently, depending on the pathogen. Numerous publications exist concerning the relationship between microorganisms belonging to different ecological groups, the majority of which concern the interaction between macro-organisms and potential pathogens, or the synergistic relationship between parasitic species. However, there is still too little information concerning the role of natural microbiota in maintaining homeostasis and the relationships between particular species inhabiting the human organism.

Opis:
A number of factors are known to be involved in Candida albicans virulence, although biofilm development on the surfaces of indwelling medical devices is considered to promote superficial or systemic disease. Based on previously reported up-regulation of saccharopine and acetyllysine in biofilm cells and activation of the lysine biosynthesis/degradation pathway, we investigated the consequences of Candida albicans lysine auxotrophy on adhesion to host tissues and biofilm formation. Our data indicate that mutant strains lysΔ21/lysΔ22, defective in homocitrate synthase, and lysΔ4, defective in homoaconitase activity (the first two α-aminoadipate pathway enzymes), are able to adhere to mouse embryonic fibroblast cells (cell line NIH/3T3) to the same extent as a control strain SC5314. On the other hand, the auxotrophic mutant strains' development on mouse fibroblast monolayers was significantly reduced up to 5 h post infection. Although invasion into human-derived oral epithelial cells was unaltered, both mutant strains formed a significantly different biofilm architecture and demonstrated diminished viability during long term biofilm propagation.

Opis:
Candida species can be a reason of infections associated with high morbidity and mortality. The risk of invasive candidosis for patients admitted to intensive care units (ICUs) is increased due to immunosuppressive states, prolonged length of stay, broad-spectrum antibiotics and Candida colonization. The aim of the study was to determine selected properties of fungi isolated from patients treated in the ICUs of hospitals in Lodz. The materials were collected from the oral cavity, the tracheostomy or endotracheal tube and urine from 16 children and 35 adult. In total, 127 samples were examined to differentiate the fungal strains with used morphological and biochemical methods. Candida species were isolated from adult patients (82.9%), but were not isolated from any of the children; C. albicans was the predominant fungus (61.7%), much less frequent were C. glabrata (12.8%), C. tropicalis (6.4%) and C. kefyr, C. dubliniensis (4.3% each).The susceptibility of fungi to antimycotic drugs revealed that almost all of the strains were susceptible to nystatin (97.9%) and to amphotericin B (72.3%), and resistant to fluconazole (72.3%) and ketoconazole (57.5%). No isolation of fungi from children remaining in ICU may be an evidence of high sanitary regime at these wards; fungi from the genus Candida are the etiological factors for ICU infections; 3/5 of them are caused by C. albicans, mostly of the code 2 576 174, characteristic for strains isolated from hospitalized patients; it is necessary to determine the species of the fungus and its susceptibility to drugs, which allows to conduct effective therapy; prophylactic administration of fluconazole leads to an increase in the number of strains resistant to this chemotherapeutic agent; in the antifungal local treatment, nystatin should be a drug of choice as the drug to which most fungi are susceptible.

We applied the in vitro adherence test, primarily described by Kimura and Pearsall and modified by Macura. The strongest adherence was found between both fungi and epithelial cells isolated from a HIV+ person. The adherence of C. albicans isolated from HIV+ patients was significantly stronger to epithelium collected from HIV+ than HIV- persons.

Opis:
A fast development of a wide variety of proteomic techniques supported by mass spectrometry coupled with high performance liquid chromatography has been observed in recent years. It significantly contributes to the progress in research on the cell wall, very important part of the cells of pathogenic fungi. This complicated structure composed of different polysaccharides, proteins, lipids and melanin, plays a key role in interactions with the host during infection. Changes in the set of the surface-exposed proteins under different environmental conditions provide an effective way for pathogens to respond, adapt and survive in the new niches of infection. This work summarizes the current state of knowledge on proteins, studied both qualitatively and quantitatively, and found within the cell wall of fungal pathogens for humans, including Candida albicans, Candida glabrata, Aspergillus fumigatus, Cryptococcus neoformans and other medically important fungi. The described proteomic studies involved the isolation and fractionation of particular sets of proteins of interest with various techniques, often based on differences in their linkages to the polysaccharide scaffold. Furthermore, the proteinaceous contents of extracellular vesicles ("virulence bags") of C. albicans, C. neoformans, Histoplasma capsulatum and Paracoccidioides brasiliensis are compared, because their production can partially explain the problem of non-classical protein secretion by fungi. The role assigned to surface-exposed proteins in pathogenesis of fungal infections is enormously high, thus justifying the need for further investigation of cell wall proteomes.

Opis:
The frequency of severe systemic fungal diseases has increased in the last few decades. The clinical use of antibacterial drugs, immunosuppressive agents after organ transplantation, cancer chemotherapy, and advances in surgery are associated with increasing risk of fungal infections. Opportunistic pathogens from the genera Candida and Aspergillus as well as pathogenic fungi from the genus Cryptococcus can invade human organism and may lead to mucosal and skin infections or to deep-seated mycoses of almost all inner organs, especially in immunocompromised patients. Nowadays, there are some effective antifungal agents, but, unfortunately, some of the pathogenic species show increasing resistance. The identification of fungal virulence factors and recognition of mechanisms of pathogenesis may lead to development of new efficient antifungal therapies. This review is focused on major virulence factors of the most common fungal pathogens of humans: Candida albicans, Aspergillus fumigatus and Cryptococcus neoformans. The adherence to host cells and tissues, secretion of hydrolytic enzymes, phenotypic switching and morphological dimorphism contribute to C. albicans virulence. The ability to grow at 37°C, capsule synthesis and melanin formation are important virulence factors of C. neoformans. The putative virulence factors of A. fumigatus include production of pigments, adhesion molecules present on the cell surface and secretion of hydrolytic enzymes and toxins.
