Parasites often have shorter generation times and, in some cases, faster mutation rates than their hosts, which can lead to greater population differentiation in the parasite relative to the host. Here we present a population genetic study of two ectoparasitic flies, Olfersia spinifera and Olfersia aenescens compared with their respective bird hosts, great frigatebirds (Fregata minor) and Nazca...

—We investigated the daily activity patterns of seven species of turtles in a northern Indiana lake over 10 y using the numbers of captures in fyke nets as an index of activity. Chrysemys picta and Graptemys geographica were active throughout the daylight hours. Sternotherus odoratus and Chelydra serpentina were crepuscular. Trachemys scripta was diurnal; however, its activity was concentrated ...

In the current study a comparative proteomic approach was used to investigate the response of the human pathogen black yeast Exophiala dermatitidis toward temperature treatment. Protein functional analysis - based on cellular process GO terms - was performed on the 32 temperature-responsive identified proteins. The bioinformatics analyses and data presented here provided novel insights into the...

We report a case of black grain mycetoma in a 74-years-old man who presented with a 50-yr. history of sinus-tract formation in the right foot. This is the first case of an Exophiala jeanselmeimycetoma successfully treated with itraconazole. In addition a review of the literature on this subject was done.

Infections of Fusarium spp. and Exophiala spp. are often chronic, recalcitrant, resulting in significant morbidity, causing discomfort, disfigurement, social isolation. Systemic disseminations happen in compromised patients, which are often refractory to available antifungal therapies and thereby lead to death. The antimicrobial photodynamic therapy (aPDT) has been demonstrated to effectively i...

The melanized dimorphic fungus Exophiala dermatitidis is detected mainly in the respiratory tract of patients with CF. However, how to determine clinical manifestation and indication for treatment bronchopulmonary mycosis difficult have not been systematically established yet. To conduct a prospective cohort study lasting 12 months. 200 sputum-producing cystic fibrosis who were ≥6 years age att...

Subcutaneous phaeohyphomycosis is a disease caused by dematiaceous fungi that develops mainly in immunocompromised patients. Lesions are generally located on the lower limbs. The present report describes a case of phaeohyphomycosis in an immunocompetent patient in whom a subcutaneous abscess was located in an unusual site, on the left hemiscrotum. The abscess was treated successfully with oral ...

A screening of 2300 samples of faeces from humans with and without underlying disease revealed that the black yeast Exophiala dermatitidis is present at a frequency of 5.2 per thousand (n=12). Eight individuals positive for the fungus had diarrhoea at the moment of its isolation, out of 11 where relevant information was available. Judging from repeated isolation over several weeks in one patien...

In this study, we evaluated the in vitro activity of anidulafungin against selected mold isolates. Anidulafungin showed promising activity against Bipolaris spicifera, Exophiala jeanselmei, Fonsecaea pedrosoi, Madurella mycetomatis, Penicillium marneffei, Phialophora verrucosa, Pseudallescheria boydii, Sporothrix schenckii, and Wangiella dermatitidis.

Africorchestia, a new genus of coastal sand-hoppers (Amphipoda, Talitridae), is described from western Africa and southwestern Europe. Africorchestia includes five species: A. fischeri (H. Milne Edwards, 1830); A. quadrispinosa (K.H. Barnard, 1916); A. skoogi (Stebbing, 1922); A. spinifera (Mateus, 1962); and A. tricornuta (Shoemaker, 1920).
