In the present work, fungi present in the grapevine's phyllosphere collected from the main demarcated wine regions of Portugal were identified, and their phylogenetic relationships was analyzed. A total of 46 vine samples (leaves and berries) were collected from different parts of the country, being isolated a total of 117 fungal colonies that were identified to the genus level and sequenced in the following genetic regions: internal transcribed spacer region and 18S rRNA and β-tubulin gene. Next, a phylogenetic tree reconstruction for each genetic region was built...

Background: Chronic obstructive pulmonary disease (COPD) is now recognized as a systemic disorder with many comorbidities. Atopy in patients with COPD and upper airways symptoms has not been characterized. Objective: We investigated the occurrence and impact of aeroallergen sensitisation in patients with COPD and upper airways symptoms. Methods: All 41 subjects with COPD diagnosed as per Global Initiative for Chronic Obstructive Lung Disease guidelines, underwent spirometry with reversibility, computed tomography of the paranasal sinuses (CT-PNS), skin prick test (SPT) against common aeroallergens and responded to St...

The biotransformation of the lignan (-)-cubebin by filamentous fungi Aspergillus terreus and Aspergillus niger is an efficient bioprocess for obtaining (-)-hinokinin and (-)-parabenzlactone. The relevance of getting (-)-hinokinin is due to its promising effect against oral pathogens, especially S. sanguinis (both MIC and MBC 12.5 μg/mL), and other previous reported effects against Chagas disease and as anti-inflammatory. The advantage of using fungal transformation is the use of non-toxic and/or non-pollutant reagents and/or solvents in comparison with semi-synthesis...

Fever may be the only clinical symptom at the onset of infection in neutropenic cancer patients undergoing myelosuppressive chemotherapy. A prompt and evidence-based diagnostic and therapeutic approach is mandatory. A systematic search of current literature was conducted, including only full papers and excluding allogeneic hematopoietic stem cell transplant recipients. Recommendations for diagnosis and therapy were developed by an expert panel and approved after plenary discussion by the AGIHO. Randomized clinical trials were mainly available for therapeutic decisions, and new diagnostic procedures have been introduced into clinical practice in the past decade...

PURPOSE: The purpose of this study was to review the incidence and microbiology of acute postcataract surgery endophthalmitis in India. METHODS: Systematic review of English-language PubMed referenced articles on endophthalmitis in India published in the past 21 years (January 1992-December 2012), and retrospective chart review of 2 major eye care facilities in India in the past 5 years (January 2010-December 2014) were done. The incidence data were collected from articles that described "in-house" endophthalmitis and the microbiology data were collected from all articles...

Koji products have been considered as an effective fermented food consumed in East Asia with many health benefits. Particularly, rice koji with Aspergillus terreus (RAT) has been reported to be able to prevent hyperlipidemia and hepatic steatosis through regulating cholesterol synthesis. Despite its biological activities, there is a lack of comprehensive information to give an assurance of its safety. Therefore, the objective of this study was to perform a series of toxicological studies (repeated dose oral toxicity and genotoxicity) according to test guidelines published by the Organization for Economic Cooperation and Development...

Caspofungin targets cell wall β-1,3-glucan synthesis and is the international consensus guideline-recommended salvage therapy for invasive aspergillosis. Although caspofungin is inhibitory at low concentrations, it exhibits a paradoxical effect (reversal of growth inhibition) at high concentrations by an undetermined mechanism. Treatment with caspofungin at either the growth-inhibitory concentration (0.5 μg/ml) or paradoxical growth-inducing concentration (4 μg/ml) for 24 h caused similar abnormalities, including wider, hyperbranched hyphae, increased septation, and repeated hyphal tip lysis, followed by regenerative intrahyphal growth...

Molds are responsible for postharvest spoilage of citrus fruits. The objective of this study was to evaluate the effect of temperature on growth rate and the time to visible growth of Aspergillus niger strains isolated from citrus fruits. The growth of these strains was studied on agar lime medium (AL) at different temperatures, and growth rate was estimated using the Baranyi and Roberts model (Int. J. Food Microbiol. 23:277-294, 1994). The Rosso et al. cardinal model with inflexion (L. Rosso, J. R. Lobry, S...

Airborne microorganisms occur ubiquitously in the ambient air. Besides allergic and irritative-toxic effects, they can cause infections after inhalation. Occupational studies have shown that an increased incidence of respiratory diseases is found in adequately exposed workers. In addition to respiratory diseases, severe systemic infections can also occur in particular cases, such as in the case of a hantavirus infection that is recognized as an occupational disease. In studies from environmental medicine, respiratory diseases have also been observed in residents living in the vicinity of livestock facilities and evaporative cooling towers...

Although. Aspergillus spp infection is not the major cause of morbidity in Intensive Care Units (ICUs), mortality among patients treated for it is tremendous. Moreover, invasive aspergillosis (IA) is an independent risk factor of hospital costs and length of stay. The prevalence of this disease is inversely correlated with the immunocompetence of individuals; for instance, the incidence of IA among patients with leukemia is estimated as high as 12.7%. Although there is a significant improvement in the antifungal armamentarium, the appropriate treatment is still being given too late, mostly because of late diagnosis...

OBJECTIVES: Antibiotic resistance among Gram-negative pathogens isolated from ventilator-associated pneumonia (VAP) poses a grave threat in intensive care unit (ICU) patients. The aim of this study was to assess the prevalence of pathogens in ICU patients and their drug resistance profile. The prevalence of extended-spectrum β-lactamases (ESBLs), AmpC β-lactamases and metallo-β-lactamases (MBLs) was also assessed. METHODS: Tracheal aspirates were collected aseptically from 87 ICU patients between May 2012 and January 2014...

The European Conference on Infections in Leukemia (ECIL) provides recommendations for diagnostic strategies and prophylactic, pre-emptive or targeted therapy strategies for various types of infection in patients with hematologic malignancies or hematopoietic stem cell transplantation recipients. Meetings are held every two years since 2005 and evidence-based recommendations are elaborated after evaluation of the literature and discussion among specialists of nearly all European countries. In this manuscript, the ECIL group presents the 2015-update of the recommendations for the targeted treatment of invasive candidiasis, aspergillosis and mucormycosis...

Ergosterol, a fungus-specific sterol enriched in cell plasma membranes, is an effective antifungal drug target. However, current knowledge of the ergosterol biosynthesis process in the saprophytic human fungal pathogen Aspergillus fumigatus remains limited. In this study, we found that two endoplasmic reticulum-localized sterol C-24 reductases encoded by both erg4A and erg4B homologs are required to catalyze the reaction during the final step of ergosterol biosynthesis. Loss of one homolog of Erg4 induces the overexpression of the other one, accompanied by almost normal ergosterol synthesis and wild-type colony growth...
