Targeting Crf Transglycosylases With Neutralizing Antibody Is Relevant but Not Sufficient to Erase Fungal Burden in a Neutropenic Rat Model.

is an airborne opportunistic fungal pathogen responsible for severe infections. Among them, invasive pulmonary aspergillosis has become a major concern as mortality rates exceed 50% in immunocompromised hosts. In parallel, allergic bronchopulmonary aspergillosis frequently encountered in cystic fibrosis patients, is also a comorbidity factor.

Insecticide resistance in Anopheles mosquitoes : additional obstacles in the battle against malaria.

Mosquitoes of the genus Anopheles are malaria vectors in tropical areas and were of course designated as primary targets by programs for malaria control. Repellent sprays, indoor use of insecticides, and massive delivery of mosquito nets are standard examples of the means widely used to combat malaria. This synthetic review supplies an overview of all of the modes of resistance developed by Anopheles mosquitoes against these human actions.

An estimation of burden of serious fungal infections in France.

Objective Of The Study: An estimation of burden of serious fungal diseases in France is essential data to inform public health priorities on the importance of resources and research needed on these infections. In France, precise data are available for invasive fungal diseases but estimates for several other diseases such as chronic and immunoallergic diseases are by contrast less known.

Materials And Methods: A systematic literature search was conducted using the Web of Science Platform.

Use of calcofluor-blue brightener for the diagnosis of Pneumocystis jirovecii pneumonia in bronchial-alveolar lavage fluids: A single-center prospective study.

The biological diagnosis of Pneumocystis jirovecii pneumonia (PjP) is based on the investigation of respiratory fluids by conventional staining methods and/or molecular biology. Diagnostic performance of an in-house technique based on calcofluor-blue brightener for the direct detection of P. jirovecii cysts was prospectively assessed in bronchial-alveolar lavage fluids (BALF) from patients with a suspected PjP infection over a three-year period in a single center: the diagnostic yield was compared to that of a commercial kit based on monoclonal immunofluorescence assay (IFA) on replicate smears.

Multicenter Comparison of the Etest and EUCAST Methods for Antifungal Susceptibility Testing of Candida Isolates to Micafungin.

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.

[Gastrointestinal parasitic carriage in adopted children].

Introduction: Intestinal parasitoses are very common infections in tropical areas. By contrast, they are rarely diagnosed in developed countries, and are mostly seen in specific populations.

Patients And Methods: This analytical observational study was longitudinally performed in a French university hospital (2007-2011).

Epidemiological Outbreaks of Pneumocystis jirovecii Pneumonia Are Not Limited to Kidney Transplant Recipients: Genotyping Confirms Common Source of Transmission in a Liver Transplantation Unit.

Over a 5-month period, four liver transplant patients at a single hospital were diagnosed with Pneumocystis jirovecii pneumonia (PCP). This unusually high incidence was investigated using molecular genotyping. Bronchoalveolar lavage fluids (BALF) obtained from the four liver recipients diagnosed with PCP were processed for multilocus sequence typing (MLST) at three loci (SOD, mt26s, and CYB).

Pulmonary toxoplasmosis in immunocompromised patients with interstitial pneumonia: a single-centre prospective study assessing PCR-based diagnosis.

Aims: Pulmonary toxoplasmosis has become a very rare parasitic infection since the advent of highly active antiretroviral therapies. It is generally diagnosed by the direct microscopic observation of Toxoplasma gondii tachyzoites in bronchoalveolar lavage fluid (BALF). The aim of this study was to assess possible improvements in diagnostic performance associated with the use of real-time PCR.

Impact of advice given to travelers concerning the main infectious risks associated with traveling in the tropics.

Introduction: The prevention of sanitary risks related to traveling in the tropics implies delivering a large amount of information to travelers. The objective of our study was to assess the knowledge acquired by travelers during a pre-travel consultation.

Methods: A before and after study was conducted among 202 travelers having consulted at the Tours international vaccine center.

[Bacterial flora in blepharitis].

Introduction: Blepharitis has multiple, poorly defined origins. The goal of this study was to investigate the bacterial flora present in patients affected with blepharitis in comparison with healthy subjects, so as to understand the role of bacterial etiologies in blepharitis.

Materials And Methods: Fifty-four patients with blepharitis and 50 healthy controls participated in this study.

Assessment of Aspergillus fumigatus burden in lungs of intratracheally-challenged turkeys (Meleagris gallopavo) by quantitative PCR, galactomannan enzyme immunoassay, and quantitative culture.

Aspergillus fumigatus remains a major respiratory pathogen in birds and treatment is still difficult. We challenged different groups of few-day-old turkeys via intratracheal aerosolisation with increasing concentrations (10(5) up to 10(8)) of conidia using a MicroSprayer(®) device. The fungal burden was assessed by real-time PCR, galactomannan dosage, CFU counting and histopathological evaluation in order to provide a comparison of these results within each inoculum groups.

Prospective assessment of FilmArray® technology for the rapid identification of yeast isolated from blood cultures.

We prospectively assessed the ability of FilmArray® device to identify fungal species involved in bloodstream infections. It succeeded in identifying 85.7% of isolates.
