We describe a 22-year-old soldier with 19% total body surface area burns, polytrauma, and sequence- and culture-confirmed Pythium aphanidermatum wound infection. Antemortem histopathology suggested disseminated Pythium infection, including brain involvement; however, postmortem PCR revealed Cunninghamella elegans, Lichtheimia corymbifera, and Saksenaea vasiformis coinfection. The utility of molecular diagnostics in invasive fungal infections is discussed.

Methods: We systematically searched six databases from 2000 to 2014. Random pairs of independent reviewers critically appraised eligible systematic reviews using the Scottish Intercollegiate Guidelines Network criteria.
Xenotransplantation of human cancers into immunodeficient mice is a very useful approach for studying human tumor biology. However, the occasional occurrence of lymphomagenesis in some mice can spoil the model and must be investigated in detail. We found that a high percentage (32.

In a previous study we used morphology and sequences of the nuclear ribosomal internal transcribed spacer region (ITS) and the glyceraldehyde-3-phosphate dehydrogenase (gpd) gene to identify species within a set of 99 clinical Curvularia isolates from the USA. Seventy-two isolates could be identified while the remaining 27 isolates belonged in three unclassified clades that were tentatively labelled Curvularia sp.

The taxonomy of the genus is not yet resolved and, in order to facilitate identification of clinical specimens, we have studied a set of clinical and environmental Acrophialophora isolates by morphological and molecular analyses. This set included the available type strains of Acrophialophora species and similar fungi, some of which were considered by various authors to be synonyms of A.

The specific internal cross calibration protocol requirements necessary for this uncertainty budget to be valid are discussed.

Diabetes mellitus impacts a substantial number of people worldwide and despite numerous antidiabetic medications available, approximately half of the drugs do not attain their recommended target, glycated hemoglobin (HbA1c). Recently, the kidney and its role in glucose reabsorption through the sodium/glucose cotransporter 2 (SGLT2) has been the target for novel antidiabetic treatments. Pharmacologic inhibition of SGLT2 in patients with diabetes results in increased urinary glucose excretion and decreased blood glucose levels, decreasing HbA1c levels.

Histopathologic evaluation revealed pleuritis and pneumonia with non-melanized, septate hyphae and fruiting structures identical to those of P. lilacinum.

These arthroconidial fungi are grouped in genera where the asexual-sexual connections and their taxonomic circumscription are poorly known. In the present study we explored the phylogenetic relationships of two of these ascomycetous genera, Arthrographis and Arthropsis.

However, clinicomicrobiological characteristics and treatment of many AFI agents remain poorly defined. We report the first human case of infection with Westerdykella dispersa, an emergent cause of AFI, which was successfully treated in a neutropenic pediatric patient.

Recently, the taxonomy of the genus has been reevaluated, and the most relevant species, Ochroconis gallopava, was transferred to the new genus Verruconis. Due to the important clinical implications of these fungi and based on the recent classification, it was of interest to know the spectra of Ochroconis and Verruconis species in clinical samples received in a reference laboratory in the United States.

In this study, a novel and rapid pre-screening method was developed to detect the production of chemical inhibitors of this system (quorum-quenching compounds) by bacteria isolated from marine and estuarine waters. This method involves direct screening of mixed populations on an agar plate, facilitating specific isolation of bioactive colonies.
