Prevalence of human pathogens of the clade Nakaseomyces in a culture collection-the first report on Candida bracarensis in Poland.

Human pathogens belonging to the Nakaseomyces clade include Candida glabrata sensu stricto, Candida nivariensis and Candida bracarensis. Their highly similar phenotypic characteristics often lead to misidentification by conventional laboratory methods. Therefore, limited information on the true epidemiology of the Candida glabrata species complex is available.

Nested PCR for the detection of Aspergillus species in maxillary sinus samples of patients with chronic sinusitis.

Background: Fungal rhinosinusitis has become an increasingly recognized disease, being Aspergillus species responsible for most of the cases. Its diagnosis is quite difficult because of the non-specific symptoms and low sensitivity of the current diagnostic methods.

Aims: An Aspergillus-specific nested polymerase chain reaction (PCR) assay using biopsy specimens taken from the maxillary sinuses was performed in order to assess its usefulness.

Preliminary antifungal activity assay of selected chlorine-containing derivatives of xanthone and phenoxyethyl amines.

The aim of this study was to evaluate antifungal activity in a diverse group of chlorine-containing xanthone and phenoxyethyl amine derivatives - and to select the most promising compounds for further studies. The antifungal efficacy of 16 compounds was tested with qualitative and quantitative methods against both reference and clinical strains of dermatophytes, moulds and yeasts. The disc-diffusion method has demonstrated that from 16 tested compounds, 7 possess good antifungal activity against dermatophytes and/or moulds while none of them has shown good efficacy against yeasts or bacterial strains.

Molecular characterization of Candida isolates from intensive care unit patients, Krakow, Poland.

Background: Over the last decades, Candida species have emerged as important pathogens in immunocompromised patients. Nosocomial infections are mainly of endogenous origin. Nevertheless, some cases of exogenous candidiasis have also been reported.

Molecular epidemiology of Candida albicans and Candida glabrata strains isolated from intensive care unit patients in Poland.

Over the last decades, Candida spp have been responsible for an increasing number of infections, especially in patients requiring intensive care. Knowledge of local epidemiology and analysis of the spread of these pathogens is important in understanding and controlling their transmission. The aim of this study was to evaluate the genetic diversity of 31 Candida albicans and 17 Candida glabrata isolates recovered from intensive care unit patients from the tertiary hospital in Krakow between 2011-2012.

Dermatophytes isolated from superficial fungal infections in Krakow, Poland, between 1995 and 2010.

Superficial fungal infections due to dermatophytes are common over the world and their frequency is constantly increasing. The aim of our study was to discuss fungal infections with frequency of occurrence, clinical stages and aetiology in patients admitted to dermatological ward and microbiological laboratory of the specialist hospital in Krakow. Investigations performed between 1995 and 2010 included the group of 5333 individuals.

[Evaluation of chromogenic media in microbiological diagnostics].

The aim of the study was the evaluation ofchromogenic agars as a screening media in the routine microbiological diagnostics. 627 clinical samples were cultured on the chromogenic media: chromID S. aureus, chromID MRSA, chromID CPS3 and chromID ESBL from bioMerieux.
