Influence of culture conditions on production of flavour compounds by 29 ligninolytic Basidiomycetes
1990
The odorous volatile metabolites produced by 29 ligninolytic Basidiomycete strains (identified by gas chromatography coupled to mass spectroscopy — GC-MS) and the flavour quality of their cultures were investigated on 6 different liquid media tested with and without agitation. 113 compounds were identified, the most numerous being alcohols (2-methyl 1-propanol, 2-methyl 1-butanol, 3 methyl 1-butanol, 2 phenyl ethanol, 3,4, dimethoxy phenyl methanol, 4 vinyl phenol), aldehydes (3, 4 dimethoxybenzaldehyde) and ketones (4-hydroxy 3-methyl 2-phenyl 2-cyclopentene 1-one). One third of these compounds possessed an aromatic skeleton. The influences of medium composition and agitation conditions on…

Milzu apaļpūpēdis 103 cm apkārtmērā
2019
On September 2nd, 1922, the 103 cm in circumference giant puffball fungus was found in the park of the Rīgas Sarkankalna vājprātīgo iestāde. Nowadays it is in the Botany and Mycology collections of the Museum of the University of Latvia. The article provides information on finding and sending the fungus to the University of Latvia, as well as a description of the species of the giant puffball (Calvatia gigantea).
The Acharius Medals 2014 awarded to P.L. Nimis and P. Crittenden
2014
The Acharius Medal rewards distinguished lichenologists in recognition of their life work with a silver medal in honour of Erik Acharius, the “father of Lichenology” was awarded to P.L. Nimis and P. Crittenden during the 10th International Mycological Congress held in Bangkok (Thailand).
Novel Pulmonary Vasculitis with Splendore-Hoeppli Reaction in Grey Seals (Halichoerus grypus) Associated with Otostrongylus circumlitus Infection.
2019
Summary Lungworm infection in seals is an important cause of morbidity and mortality, inducing bronchopneumonia and affecting population dynamics in some areas of the world. We present a series of cases of lungworm infection in grey seals (Halichoerus grypus) associated with novel, significant and unusual pulmonary vascular changes. Grey seals (n = 180) that were stranded, in rehabilitation or in long-term captivity in the UK were subjected to post-mortem examination between 2012 and 2018. Lung tissue was collected from 47 individuals for histopathological examination. Polymerase chain reaction (PCR) on formalin-fixed and paraffin wax-embedded (FFPE) material was attempted for parasite iden…
Evaluation of the Role of Candida albicans Agglutinin-Like Sequence (Als) Proteins in Human Oral Epithelial Cell Interactions
2012
The fungus C. albicans uses adhesins to interact with human epithelial surfaces in the processes of colonization and pathogenesis. The C. albicans ALS (agglutinin-like sequence) gene family encodes eight large cell-surface glycoproteins (Als1-Als7 and Als9) that have adhesive function. This study utilized C. albicans Δals mutant strains to investigate the role of the Als family in oral epithelial cell adhesion and damage, cytokine induction and activation of a MAPK-based (MKP1/c-Fos) signaling pathway that discriminates between yeast and hyphae. Of the eight Δals mutants tested, only the Δals3 strain showed significant reductions in oral epithelial cell adhesion and damage, and cytokine pro…
Candida albicans Yeast and Hyphae are Discriminated by MAPK Signaling in Vaginal Epithelial Cells
2011
We previously reported that a bi-phasic innate immune MAPK response, constituting activation of the mitogen-activated protein kinase (MAPK) phosphatase MKP1 and c-Fos transcription factor, discriminates between the yeast and hyphal forms of Candida albicans in oral epithelial cells (ECs). Since the vast majority of mucosal Candida infections are vaginal, we sought to determine whether a similar bi-phasic MAPK-based immune response was activated by C. albicans in vaginal ECs. Here, we demonstrate that vaginal ECs orchestrate an innate response to C. albicans via NF-κB and MAPK signaling pathways. However, unlike in oral ECs, the first MAPK response, defined by c-Jun transcription factor acti…
Using a Multi-Locus Microsatellite Typing method improved phylogenetic distribution of Candida albicans isolates but failed to demonstrate associatio…
2012
EA MERS CT3 Enjeu 3; International audience; The dimorphic yeast Candida albicans is a component of the normal microflora at the mucosal surfaces of healthy individuals. It possesses an array of phenotypic properties considered as virulence traits that contribute to pathogenicity of the yeast in immuno-compromised patients. We addressed the question of the pathogenicity of lineages of C. albicans with regard to their genotype in three series of C. albicans isolates (a series of commensal isolates collected in healthy individuals, a group of bloodstream isolates and a group of non-bloodstream clinical isolates) using a Multi-Locus Microsatellite Typing (MLMT) approach based on the analysis o…
Caution on the assessment of intestinal parasitic load in studying parasite-mediated sexual selection: the case of Blackbirds coccidiosis.
2009
6 pages; International audience; The parasite-mediated sexual selection (PMSS) theory has led to an increasing number of experimental studies essentially focussed on blood parasites. Currently, more research is being carried out on intestinal parasites in relationship to this theory. Before testing the theory with gastrointestinal parasites, it is important: (i) to determine an optimal research methodology to obtain an accurate assessment of parasite burden and (ii) to have information about life-history traits of the parasite to interpret data appropriately. In this study, we present data on oocyst output of Isosporaturdi in the faeces of blackbirds (Turdus merula) that illustrate the impo…
