Molecular epidemiology of Aspergillus collected from cystic fibrosis patients

Background - Aspergillus respiratory infection is a common complication in cystic fibrosis (CF) and is associated with loss of pulmonary function and allergic disease. Methods - Fifty-three Aspergillus isolates recovered from CF patients were identified to species by Internal Transcribed Spacer Region (ITS), β-tubulin, and calmodulin sequencing. Results - Three species complexes (Terrei, Nigri, and Fumigati) were found. Identification to species level gave a single Aspergillus terreus sensu stricto, one Aspergillus niger sensu stricto and 51 Aspergillus fumigatus sensu stricto isolates. No cryptic species were found. Conclusions - To our knowledge, this is the first prospective study of Aspergillus species in CF using molecular methods. The paucity of non-A. fumigatus and of cryptic species of A. fumigatus suggests a special association of A. fumigatus sensu stricto with CF airways, indicating it likely displays unique characteristics making it suitable for chronic residence in that milieu. These findings could refine an epidemiologic and therapeutic approach geared to this pathogen.

Beach sand and the potential for infectious disease transmission: observations and recommendations

Recent studies suggest that sand can serve as a vehicle for exposure of humans to pathogens at beach sites, resulting in increased health risks. Sampling for microorganisms in sand should therefore be considered for inclusion in regulatory programmes aimed at protecting recreational beach users from infectious disease. Here, we review the literature on pathogen levels in beach sand, and their potential for affecting human health. In an effort to provide specific recommendations for sand sampling programmes, we outline published guidelines for beach monitoring programmes, which are currently focused exclusively on measuring microbial levels in water. We also provide background on spatial distribution and temporal characteristics of microbes in sand, as these factors influence sampling programmes. First steps toward establishing a sand sampling programme include identifying appropriate beach sites and use of initial sanitary assessments to refine site selection. A tiered approach is recommended for monitoring. This approach would include the analysis of samples from many sites for faecal indicator organisms and other conventional analytes, while testing for specific pathogens and unconventional indicators is reserved for high-risk sites. Given the diversity of microbes found in sand, studies are urgently needed to identify the most significant aetiological agent of disease and to relate microbial measurements in sand to human health risk.

CMOS indoor light energy harvesting system for wireless sensing applications

This book discusses in detail the CMOS implementation of energy harvesting. The authors describe an integrated, indoor light energy harvesting system, based on a controller circuit that dynamically and automatically adjusts its operation to meet the actual light circumstances of the environment where the system is placed. The system is intended to power a sensor node, enabling an autonomous wireless sensor network (WSN). Although designed to cope with indoor light levels, the system is also able to work with higher levels, making it an all-round light energy harvesting system. The discussion includes experimental data obtained from an integrated manufactured prototype, which in conjunction with a photovoltaic (PV) cell, serves as a proof of concept of the desired energy harvesting system. © 2016 Springer International Publishing.

Fungal contamination of sandpits from recreational parks and schools: a potential risk for human health

Sandpits used by children are frequently visited by wild life which constitutes a source of fungal pathogens and allergenic fungi. This study aimed to take an unannounced snapshot of the urban levels of fungal contaminants in sands, using for this purpose two public recreational parks, three elementary schools and two kindergartens. All samples were from Lisbon and neighboring municipalities and were tested for fungi of clinical interest. Potentially pathogenic fungi were isolated from all samples besides one. Fusarium dimerum (32.4%) was found to be the dominant species in one park and Chrysonilia spp. in the other (46.6%). Fourteen different species and genera were detected and no dermatophytes were found. Of a total of 14 species and genera, the fungi most isolated from the samples of the elementary schools were Penicillium spp. (74%), Cladophialophora spp. (38%) and Cladosporium spp. (90%). Five dominant species and genera were isolated from the kindergartens. Penicillium spp. was the only genus isolated in one, though with remarkably high counts (32500 colony forming units per gram). In the other kindergarten Penicillium spp. were also the most abundant species, occupying 69% of all the fungi found. All of the samples exceeded the Maximum Recommended Value (MRV) for beach sand defined by Brandão et al. 2011, which are currently the only quantitative guidelines available for the same matrix. The fungi found confirm the potential risk of exposure of children to keratinophilic fungi and demonstrates that regular cleaning or replacing of sand needs to be implemented in order to minimize contamination.

Bibliotecas na saúde… e a saúde nas bibliotecas?

Em arquivos e bibliotecas a presença de fungos é considerada nefasta pelas suas implicações na conservação e leitura de documentos históricos e pela sua associação a problemas de saúde sentidos pelos funcionários e utentes que frequentam estes locais. De acordo com alguns autores, os problemas de saúde mais reportados por funcionários em Bibliotecas e Arquivos são dermatite, rinite, alergias e asma. Embora revestida de inegável importância, existem poucos estudos internacionais sobre a temática e, em Portugal, a contaminação fúngica em ambiente arquivístico e em bibliotecas é ainda muito pouco conhecida. O estudo realizado em quatro Arquivos Portugueses teve como objectivo conhecer a contaminação fúngica, contribuindo para a análise da qualidade do ar interior desses espaços e sua comparação com estudos internacionais. Para isso foram recolhidas amostras de ar e de superfícies e estas foram analisadas por métodos clássicos de cultura e, quando necessário, por métodos de biologia molecular. A avaliação foi feita quantitativa e qualitativamente, considerando os requisitos legais em vigor. No que respeita à análise do ar, o número de unidades formadoras de colónias (UFC)/m3 nunca excedeu as 500 (limite legislado), tendo sido verificada contaminação interior em todos os locais estudados. Comparativamente aos estudos realizados anteriormente em contextos semelhantes foram encontrados níveis elevados de contaminação por leveduras nas amostras de ar analisadas em Arquivos Portugueses. Não foi identificado nenhum fungo patogénico neste estudo, mas em quase todas as amostras estavam presentes fungos potencialmente toxinogénicos. Dentro do grupo dos Aspergillus, o A.versicolor mostrou predominância, tendo este fungo reconhecidas capacidades de emissão de micotoxinas em ambiente de interior. A inclusão de amostras de superfície revelou-se vital para conhecer todo o espectro fúngico existente em cada um dos locais estudados, incluindo a detecção de Stachybotrys chartarum e a do fungo potencialmente queratinofílico, Chrysosporium carmichaelli. Tanto para a saúde como para a conservação, o recente estudo realizado em quatro arquivos permitiu retirar importantes conclusões e reforçar a necessidade de vigilância, sendo também útil para a definição de padrões de qualidade no campo do património cultural.

New approach to study the real exposure to fungi in cork industry: nasal swabs mycobiota investigation coupled with screening on fungal resistance to azoles

The permanent contact with cork may lead to constant exposure to fungi, raising awareness as a potential occupational hazard in the cork industry.The presence of fungi belonging to the Penicillium glabrum complex has been associated with the development of respiratory diseases such as suberosis, one of the most prevalent diseases among workers from cork industries, besides occupational asthma. Azoles are used as pesticides but also the first line therapy in the treatment of Aspergillus infections; azole-resistance as been described as to have also an environmental source and is considered an emerging public health problem.The aim of this work was to characterize fungal distribution and to evaluate the presence of azole-resistant Aspergillus isolates in nose swab samples from the cork industry workers.
