Candida parapsilosis

Ryan P Brothers, Steven D Daveluy
A 61 year old immunosuppressed male presented with a non-healing wound following a rose thorn injury. Initial cultures revealed Candida parapsilosis, however histology confirmed squamous cell carcinoma in-situ (SCCis). This case emphasizes the importance of biopsy and cultures as fungal infection and SCCis often have similar, non-specific clinical appearances.

In the Asia-Pacific region, Candida albicans is the predominant Candida species causing invasive candidiasis/candidemia in Australia, Japan, Korea, Hong Kong, Malaysia, Singapore and Thailand whereas C. tropicalis is the most frequently encountered Candida species in Pakistan and India. Invasive isolates of C. albicans, C. parapsilosis complex and C. tropicalis remain highly susceptible to fluconazole (>90% susceptible). Fluconazole resistance (6.8-15%), isolates with the non-wild-type phenotype for itraconazole susceptibility (3...

We evaluated the in vitro antifungal activity of diphenyl diselenide and ebselen against echinocandin-susceptible and -resistant strains of Candida parapsilosis using the broth microdilution method. Diphenyl diselenide (MIC range=1-8μg/mL) and ebselen (MIC range=0.25-4μg/mL) showed in vitro activity against echinocandin-susceptible isolates. However, ebselen also showed the highest antifungal activity against echinocandin-resistant strains (MIC range=0.06-4μg/mL). This study demonstrated that the antifungal potential of diphenyl diselenide and ebselen deserves further investigation using in vivo experimental protocols...

The cell free extracts of Candida parapsilosis ATCC 7330 are more efficient than the whole resting cells of the yeast in the synthesis of directly usable gold nanoparticles as revealed by this systematic study. Cell free extracts yielded gold nanoparticles of hydrodynamic diameter (50-200 nm). In this study, the total protein concentration influences the nanofabrication and not only the reductase enzymes as originally thought. Powder X-ray diffraction studies confirm the crystalline nature of the gold nanoparticles...

Most cases of candidiasis have been attributed to Candida albicans, but Candida glabrata, Candida parapsilosis and Candida tropicalis, designated as non-C. albicans Candida (NCAC), have been identified as frequent human pathogens. Moreover, Candida biofilms are an escalating clinical problem associated with significant rates of mortality. Biofilms have distinct developmental phases, including adhesion/colonisation, maturation and dispersal, controlled by complex regulatory networks. This review discusses recent advances regarding Candida species biofilm regulatory network genes, which are key components for candidiasis...

BACKGROUND: Candida species are the most prevalent cause of invasive fungal infections such as candidemia. Candidemia is a lethal fungal infection among immunocompromised patients worldwide. Main pathogen is Candida albicans but a global shift in epidemiology toward non-albicans species have reported. Species identification is imperative for good management of candidemia as a fatal infection. The aim of the study is to identify Candida spp. obtained from candidemia and determination of mortality rate among this population...

The pathogenic yeast Candida parapsilosis metabolizes hydroxyderivatives of benzene and benzoic acid to compounds channeled into central metabolism including the mitochondrially-localized tricarboxylic acid cycle via the 3-oxoadipate and gentisate pathways. The orchestration of both catabolic pathways with mitochondrial metabolism as well as their evolutionary origin is not fully understood. Our results show that the enzymes involved in these two pathways operate in the cytoplasm with the exception of the mitochondrially-targeted 3-oxoadipate CoA-transferase (Osc1p) and 3-oxoadipyl-CoA thiolase (Oct1p) catalyzing the last two reactions of the 3-oxoadipate pathway...

This study characterized the protein/peptide profile of venom isolated from the spider Lasiodora sp. (Mygalomorphae, Theraphosidae) found in northeastern Brazil and determined its antimicrobial activity, toxicity against human cells, and hemolytic activity. Protein concentration of the Lasiodora sp. venom was 4.53 ± 0.38 mg/mL. SDS-PAGE showed proteins with molecular masses up to 75 kDa, some of which contained disulfide bridges. RP-HPLC analysis separate at least 12 peaks that were identified by mass spectrometry as peptides U1-theraphotoxin-Lp1a (lasiotoxin-1), U1-theraphotoxin-Lp1c (lasiotoxin-3), U3-theraphotoxin-Lsp1a (LTx5), and ω-theraphotoxin-Asp3a as well as the proteins phospholipase A2 (PLA2) and hyaluronidase...

Data about the performance of MALDI-TOF mass spectrometry against cryptic Candida species are limited. According to our findings within the C. parapsilosis species complex, microbiologists should be aware that the choice of the instrument is critical for accurate species identification due to the risk of misidentification in the clinical setting.

Candida spp. can adhere to and form biofilms over different surfaces, becoming less susceptible to antifungal treatment. Resistance of biofilms to antifungal agents is multifactorial and the extracellular matrix (ECM) appears to play an important role. Among the few available antifungals for treatment of candidaemia, only the lipid formulations of amphotericin B (AmB) and the echinocandins are effective against biofilms. Our group has previously demonstrated that miltefosine has an important effect against Candida albicans biofilms...

OBJECTIVE: Dermatomycoses are superficial fungal infections which affect the skin, hair and nails of humans and animals. Male and female patients of all ages are affected by this condition. The main etiological agents of dermatomycoses are the dermatophytes fungi of the genera Trichophyton, Microsporum and Epidermophyton, while the main yeasts belong to the genera Candida, Malassezia and Trichosporon. The variation in the distribution of dermatomycoses worldwide justify the conduction of epidemiological studies in order to contribute for the better understanding of patterns of mycological cutaneous infections...
