Until now, there has been no consensus on the best method for the detection of anti-Aspergillus antibodies, a key diagnostic tool for chronic aspergilloses. To better appreciate the usage of and confidence in these techniques, the Société Française de Mycologie Médicale (French Society for Medical Mycology; SFMM) performed a two-step survey of French experts. First, we administered an initial survey to French labs performing Aspergillus serology to depict usage of the different techniques available for Aspergillus serology...

Changes in the ecology of macrofungi are poorly understood, not only because much of their life cycle is hidden belowground, but also because experiments often miss real-world complexity and most fruitbody inventories are limited in space and time. The National Poisons Information Centre 'Tox Info Suisse' provides countrywide 24hours/7days medical advice in case of poisonings since 1966. Here, we introduce a total of 12,126 mushroom-related phone calls that were received by Tox Info Suisse between 1966 and 2014...

Sporotrichosis is a fungal infection caused by the Sporothrix species, which have distinct virulence profiles and geographic distributions. We performed a phylogenetic study in strains morphologically identified as Sporothrix schenckii from clinical specimens in Japan, which were preserved at the Medical Mycology Research Center, Chiba University. In addition, we examined the in vitro antifungal susceptibility and growth rate to evaluate their physiological features. Three hundred strains were examined using sequence analysis of the partial calmodulin gene, or polymerase chain reaction(PCR)method using newly designed species-specific primers; 291 strains were Sporothrix globosa and 9 strains were S...

BACKGROUND: The coccidian protozoa Toxoplasma gondii is an obligate intracellular parasite of humans and other warm-blooded animals. Diagnosis of toxoplasmosis is of considerable medical importance for human, especially pregnant women and immunocompromised individuals. The apply of an Escherichia coli recombinant antigen(s) would be significantly useful in developing standardization of the diagnostic tests and reducing their costs. In this study, immunoreactivity of recombinant SAG3 against sera from immunized mice and human anti-T...

Trichotillomania (TTM) is defined by the Diagnostics and Statistic Manual of Mental Disorders, 4th edition (DMS-IV) as hair loss from a patient`s repetitive self-pulling of hair. The disorder is included under anxiety disorders because it shares some obsessive-compulsive features. Patients have the tendency towards feelings of unattractiveness, body dissatisfaction, and low self-esteem (1,2). It is a major psychiatric problem, but many patients with this disorder first present to a dermatologist. An 11-year-old girl came to our department with a 2-month history of diffuse hair loss on the frontoparietal and parietotemporal area (Figure 1)...

We present the case of a 34 year-old man, HIV-positive, who had suffered a disseminated histoplasmosis treated with amphotericin B one year before his admission. He was admitted at the Infectious Diseases Muñiz Hospital with a non-lithiasic chlolecystitis. During the clinical examination perigenital skin lesions compatible with tinea cruris, as well as proximal subungual onychomycoses of toenails, were observed. Microsporum gypseum was isolated from both types of lesions. Oral terbinafine led to a good clinical response...

The case of a 22 year-old pregnant woman, suffering an infectious disease with skin lesions on the head, is presented. The patient referred a systemic mycosis 5 years before, treated with oral antifungal, with good clinical response. The mycological study of the skin clinical samples showed multiple budding yeast like elements consistent with Paracoccidioides, and the same organism was isolated in cultures. Physical examination and images studies did not show other location of the mycosis. The patient was treated with oral cotrimoxazole during pregnancy and lactation; afterwards this treatment was stopped and replaced by itraconazole by oral route at a daily dose of 200mg due to the poor clinical response observed with the first treatment...

In vitro susceptibility of 933 Candida isolates, from 16 French hospitals, to micafungin was determined using the Etest in each center. All isolates were then sent to a single center for determination of MICs by the EUCAST reference method. Overall essential agreement between the two tests was 98.5% at ±2 log2 dilutions and 90.2% at ±1 log2 dilutions. Categorical agreement was 98.2%. The Etest is a valuable alternative to EUCAST for the routine determination of micafungin MICs in medical mycology laboratories...

The small number of fungi that commonly cause disease in normal people share the capacity to grow as mycelia in the soil at 25°C and as yeast (or spherules) in mammals at 37°C. This remarkable conversion has long been a topic of interest in medical mycology. The conidia to yeast conversion has been studied by transcription profiling in several fungal species, including Histoplasma capsulatum, Paracoccidioides brasiliensis, Coccidioides spp., Blastomyces dermatitidis, and Talaromyces marneffei One limitation of transcriptional profiling is determining which genes are involved in the process of conversion to yeast as opposed to a result of conversion to yeast...
