According to epidemiological, clinical and mycological criteria, it has long been admitted that the Trichophyton mentagrophytes species includes two varieties: a zoophilic variety (var. mentagrophytes) and an anthropophilic variety (var. interdigitale) that involve the upper and the lower part of the body, respectively. The further application of molecular techniques to the characterization of dermatophyte strains showed that this classification is unreliable. The aim of our study was to assess the usefulness of PCR-RFLP (restriction fragment length polymorphism) and sequencing in the characterization of T...

Fungi cause more than a billion skin infections, more than 100 million mucosal infections, 10 million serious allergies and more than a million deaths each year. Global mortality owing to fungal infections is greater than for malaria and breast cancer and is equivalent to that owing to tuberculosis (TB) and HIV. These statistics evidence fungal infections as a major threat to human health and a major burden to healthcare budgets worldwide. Those patients who are at greatest risk of life-threatening fungal infections include those who have weakened immunity or have suffered trauma or other predisposing infections such as HIV...

OBJECTIVE/BACKGROUND: Tuberculosis (TB) continues to be a major public health problem worldwide. This is especially true in Northern Iran, which has high TB prevalence. The chronic nature of this disease is further exacerbated if it is accompanied by fungal infection, which usually remains undiagnosed and thus untreated. Thus, mycotic infections add fatal dimensions to pulmonary TB. Our objective was to determine the prevalence of invasive forms of fungal elements in sputum samples collected from patients with pulmonary TB at a reference laboratory in Ghaemshahr, Northern Iran, during the past 10years...

The objective of the present study was to assess the differences in modeled growth/AFB1 production probability and kinetic growth parameters for Aspergillus flavus inoculated as single spores or in a concentrated inoculation point (~500 spores). The experiment was carried out at 25°C and at two water activities (0.85 and 0.87) on pistachio extract agar (3%). Binary data obtained from growth and AFB1 studies were modeled using linear logistic regression analysis. The radial growth curve for each colony was fitted to a linear model for the estimation of the lag phase for growth and the mycelial growth rate...

Human infections by coelomycetous fungi are becoming more frequent and range from superficial to systemic dissemination. Traumatic implantation of contaminated plant material is the most common cause. The typical morphological feature of these fungi is the production of asexual spores (conidia) within fruiting bodies called conidiomata. This study aimed to determine the distribution of the coelomycetes in clinical samples by a phenotypic and molecular study of a large set of isolates received from a USA reference mycological institution and by obtaining the in vitro antifungal susceptibility pattern of a selected group of strains against nine antifungals...

A preliminary survey involving limited sample size was conducted to determine the spectrum of moulds and mycotoxins in wheat grains from flour mills and local markets in Nigeria. Fourteen wheat samples were analyzed for moulds using standard mycological methods and for toxic fungal metabolites using a liquid chromatography-tandem mass spectrometric method. Fusarium (range of incidence 12.5-61.7%) dominated in the wheat grains though species of Aspergillus (range of incidence 2.24-3.86%) were also recovered from the samples...

Nocardiosis is a rare cause of opportunistic infection post hematopoietic stem cell transplant (HSCT) occurring in about 0.3% of patients. The risk factors include delayed immune reconstitution, prolonged neutropenia, and graft-versus-host disease. The most common site of infection is the lung, followed by the brain and the skin. Concomitant pulmonary and central nervous system (CNS) nocardiosis is an extremely rare entity as presented in our case. We present the case of a 72-year-old male at 137 days post transplant presenting with complaints of headache and slurred speech...

REVIEW
Markus Ruhnke, Stefan Schwartz
Patients with hematological cancer have a high risk of invasive fungal diseases (IFDs). These infections are mostly life threatening and an early diagnosis and initiation of appropriate antifungal therapy are essential for the clinical outcome. Most commonly, Aspergillus and Candida species are involved. However, other non-Aspergillus molds are increasingly be identified in cases of documented IFDs. Important risk factors are long lasting granulocytopenia with neutrophil counts below 500/μl for more than 10 days or graft-versus-host disease resulting from allogeneic stem-cell transplantation...
