The effect of marine polyunsaturated fatty acids on biofilm formation by the human pathogens Candida albicans and Candida dubliniensis was investigated. It was found that stearidonic acid (18:4 n-3), eicosapentaenoic acid (20:5 n-3), docosapentaenoic

Background Polyunsaturated fatty acids (PUFAs) have antifungal properties, but the mode by which they induce their action is not always clear. The aim of the study was to investigate apoptosis as a mode of action of antifungal PUFAs (stearidonic acid

In this study the mitochondrion is regarded as a target to reveal compounds that may be used to combat various diseases. Consequently, the sexual structures of yeasts (with high mitochondrial activity) were identified as sensors to screen for various

The anti-mitochondrial antifungal hypothesis implies a link between mitochondrial activity, fungal fruiting structures and susceptibility towards mitochondrial inhibitors. Here it is shown that the oomycete, Phytophthora nicotianae fits the hypothesi

Nano scanning Auger microscopy (NanoSAM) and time-of-flight secondary ion mass spectrometry (TOF-SIMS) have been used in materials science research for some time, but NanoSAM, in particular, has only recently been applied to biological specimens. Her

It is known that acetylsalicylic acid, an anti-inflammatory and anti-mitochondrial drug, targets structure development and functions of yeasts depending on elevated levels of mitochondrial activity. Using antibody probes, we previously reported that

Using a well tested antibody specific for 3-hydroxy oxylipins, we mapped the presence of these oxylipins in selected Cryptococcus ( Filobasidiella ) species. Immunofluorescence microscopy studies revealed that these compounds are deposited on cell wa

The presence of aspirin-sensitive 3-hydroxy fatty acids (i.e. 3-OH oxylipins) in yeasts was first reported in the early 1990s. Since then, these oxidized fatty acids have been found to be widely distributed in yeasts. 3-OH oxylipins may: (1) have pot

We previously implicated 3-hydroxy oxylipins and ascospore structure in ascospore release from enclosed asci. Using confocal laser scanning microscopy on cells stained with fluorescein-coupled, 3-hydroxy oxylipin-specific antibodies, we found that ox

A novel yeast strain, CBS 10258T, was isolated from the atmosphere in central South Africa. Sequence analysis of the D1/D2 domain and internal transcribed spacer region of the novel strain indicates that it represents a novel species within the Crypt
