Detection of Histoplasma DNA from Tissue Blocks by a Specific and a Broad-Range Real-Time PCR: Tools to Elucidate the Epidemiology of Histoplasmosis.

Lack of sensitive diagnostic tests impairs the understanding of the epidemiology of histoplasmosis, a disease whose burden is estimated to be largely underrated. Broad-range PCRs have been applied to identify fungal agents from pathology blocks, but sensitivity is variable. In this study, we compared the results of a specific qPCR (.

Spectrum of antibiotic resistant bacteria and fungi isolated from chronically infected wounds in a rural district hospital in Ghana.

Background: Chronic infected wounds are generally difficult to manage and treatment can be particularly challenging in resource-limited settings where diagnostic testing is not readily available. In this study, the epidemiology of microbial pathogens in chronically infected wounds in rural Ghana was assessed to support therapeutic choices for physicians.

Methods: Culture-based bacterial diagnostics including antimicrobial resistance testing were performed on samples collected from patients with chronic wounds at a hospital in Asante Akim North Municipality, Ghana.

Molecular typing and in vitro resistance of Cryptococcus neoformans clinical isolates obtained in Germany between 2011 and 2017.

Cryptococcosis is a fungal infection of the central nervous system predominantly caused by Cryptococcus neoformans in immunocompromised patients. In several countries worldwide, up to 50% of isolates show in vitro resistance to clinically used antifungals including fluconazole. No prospective data on susceptibility to antifungal drugs are available for Germany.

Disseminated Emergomycosis in a Person with HIV Infection, Uganda.

We describe emergomycosis in a patient in Uganda with HIV infection. We tested a formalin-fixed, paraffin-embedded skin biopsy to identify Emergomyces pasteurianus or a closely related pathogen by sequencing broad-range fungal PCR amplicons. Results suggest that emergomycosis is more widespread and genetically diverse than previously documented.

Genotypes and population genetics of cryptococcus neoformans and cryptococcus gattii species complexes in Europe and the mediterranean area.

A total of 476 European isolates (310 Cryptococcus neoformans var. grubii, 150 C. neoformans var.

Identification of Fungal Pathogens in Tissue Samples from Patients with Proven Invasive Infection by Fluorescence In Situ Hybridization.

Identification of fungal pathogens in clinical samples by hybridization with short oligonucleotide probes is increasingly used in the diagnosis of invasive fungal infections. Rapid and specific fungal identification has been documented in different diagnostic settings allowing for specific patient management. Identification of fungal pathogens in formalin-fixed, paraffin-embedded tissue samples appears to be rewarding as these materials are stored in pathology archives offering an insight into the etiology of deep fungal infections that is often not achieved by non-molecular tests.

Environmental distribution of Cryptococcus neoformans and C. gattii around the Mediterranean basin.

In order to elucidate the distribution of Cryptococcus neoformans and C. gattii in the Mediterranean basin, an extensive environmental survey was carried out during 2012-2015. A total of 302 sites located in 12 countries were sampled, 6436 samples from 3765 trees were collected and 5% of trees were found to be colonized by cryptococcal yeasts.

Cryptococcosis due to Cryptococcus gattii in Germany from 2004-2013.

The fungal pathogen Cryptococcus gattii was considered to be restricted to tropic and sub- tropic regions. A recent outbreak in North America due to isolates belonging to molecular type VG II, affecting mostly non-immunocompromised hosts, documented the potential public health impact of this fungal pathogen also in temperate regions. Surveillance of these infections in Germany is challenging, as cryptococcosis is not notifiable and often C.

Molecular typing of clinical Cryptococcus neoformans isolates collected in Germany from 2004 to 2010.

Cryptococcosis is a fungal infection mostly caused by Cryptococcus neoformans. We identified agents of cryptococcosis diagnosed in Germany from 2004 to 2010. We used multi-locus sequence typing (MLST) to understand the molecular epidemiology of cryptococcosis.
