Complementarity of conventional and molecular methods in the assessment of fung...

Viegas, Carla; Gomes, Anita Q.; Sabino, Raquel

The handling of waste and compost that occurs frequently in composting plants (compost turning, shredding, and screening) has been shown to be responsible for the release of dust and air borne microorganisms and their compounds in the air. Thermophilic fungi, such as A. fumigatus, have been reported and this kind of contamination in composting facilities has been associated with increased respiratory symptoms a...


Comparison of Aspergillus species-complexes detected in different environmental...

Sabino, Raquel; Viegas, Carla; Veríssimo, Carla; Clemons, K. V.; Stevens, D. A.

Purpose: Samples from different environmental sources were screened for the presence of Aspergillus, and the distribution of the different species-complexes was determined in order to understand differences among that distribution in the several environmental sources and which of these species complexes are present in specific environmental settings. Methods: Four distinct environments (beaches, poultries, swin...


Exposure to volatile organic compounds in a composting plant

Viegas, Susana; Almeida-Silva, Marina; Viegas, Carla

Some previous studies have suggested that some of the volatile organic compounds (VOCs) found in composting plants may have a toxic effect that can influence, besides surroundings populations, workers from the composting plants. Impact of waste management to the environment and workers is already recognised as an environment and occupational health concerns. Several studies regarding the VOCs and bioaerosols em...


Aspergillus genera fungal contamination in a Portuguese composting plant

Viegas, Carla; Sabino, Raquel

Fungal contamination in composting facilities has been associated with increased respiratory and skin pathologies among compost workers. In this study we aim to characterize the fungal contamination caused by Aspergillus genera within a totally indoor composting plant located in Portugal. Air samples of 50L were collected from 6 sampling sites through an impaction method. Surfaces samples were collected by swab...


Occupational exposure to particulate matter and fungi in a composting plant: ca...

Viegas, Susana; Almeida-Silva, Marina; Sabino, Raquel; Viegas, Carla

The handling of waste can be responsible for occupational exposure to particles and fungi. The aim of this study was to characterize exposure to particles and fungi in a composting plant. Measurements of particulate matter were performed using portable direct-reading equipment. Air samples of 50L were collected through an impaction method with a flow rate of 140L/min onto malt extract agar supplemented with chl...


Exposure to fungi in dockers

Viegas, Carla; Dias, Ricardo

Several activities are ensured by dockers increase occupational exposure to several risk factors. being one of them the fungal burden from the load. In this study we aim at characterizing fungal contamination in one warehouse that storage sugar cane from a ship, and also in one crane cabinet that unload the same sugar cane from the ship. Air samples were collected from the warehouse and from inside the crane ca...


Routine screening of harmful microorganisms in beach sands: implications to pub...

Sabino, Raquel; Rodrigues, R.; Costa, I.; Carneiro, C.; Cunha, M.; Duarte, A.; Faria, N.; Ferreira, F. C.; Gargaté, M. J.; Júlio, C.; Martins, M. L.

Beaches worldwide provide recreational opportunities to hundreds of millions of people and serve as important components of coastal economies. Beach water is often monitored for microbiological quality to detect the presence of indicators of human sewage contamination so as to prevent public health outbreaks associated with water contact. However, growing evidence suggests that beach sand can harbor microbes ha...


Exposure to volatile organic compounds, particulate matter and fungi in a compo...

Viegas, Susana; Almeida-Silva, Marina; Sabino, Raquel; Viegas, Carla

Composting is an important process of solid waste management and it can be used for treatment of a variety of different wastes (green waste, household waste, sewage sludge and more). This process aims to: 1. Reduce the volumes of waste and; 2. Create a valuable product which can be recycled as a soil amendment in agriculture and gardening. A natural self-heating process involving the biological degradation of o...


Diagnosis of Tinea pedis and onychomycosis in patients from Portuguese National...

Viegas, Carla; Sabino, Raquel; Parada, Helena; Brandão, João; Carolino, Elisabete; Rosado, Laura; Verissimo, Cristina

ABSTRACT - Tinea pedis and onychomycosis are two rather diverse clinical manifestations of superficial fungal infections, and their etiologic agents may be dermatophytes, non-dermatophyte moulds or yeasts. This study was designed to statistically describe the data obtained as results of analysis conducted during a four year period on the frequency of Tinea pedis and onychomycosis and their etiologic agents. A q...
