The sooty bark disease (SBD) is an emerging disease affecting sycamore maple trees (Acer pseudoplatanus) in Europe. Cryptostroma corticale, the causal agent, putatively native to eastern North America, can be also pathogenic for humans causing pneumonitis. It was first detected in 1945 in Europe, with markedly increasing reports since 2000. Pathogen development appears to be linked to heat waves and drought epi...
Ecological restoration has the potential to accelerate the recovery of biodiversity and ecosystem services in degraded ecosystems. However, current research queries whether active restoration is necessary. We evaluated plant-pollinator networks during spring at replicated sites within an actively restored quarry, at abandoned quarries undergoing spontaneous restoration, and within a natural reference area, to c...
Introduction – Fungal spores are one of the major biological components of the air but are still poorly studied and their influence on respiratory allergic disease is not recognized. In this work, we intend to determine the importance of the atmospheric spores of Alternaria and Cladosporium in respiratory allergic disease in Beja. Methods – The atmospheric levels of Alternaria and Cladosporium spores in Beja we...
Aerobiological studies provide important information about the biological particles present in the air. Monitoring the presence of airborne fungal spores can help farmers to prevent the onset of fungal diseases that may affect both quantity and quality of crops. The fungi Fusarium spp. are among the most important phytopathogenic fungal communities with high impact at regional level by affecting important cultu...
Data about the occurrence of airborne pollen enables the creation of pollen calendars with an approximation of flowering periods for the most common allergenic plant species in a specific area. The aim of this work is to provide pollen calendar for each of the seven monitoring regions of Portugal based on 15 years of airborne sampling, in order to chart the seasonal behaviour of the main allergenic pollen types.
Background In Portugal, the pollen types most implicated in respiratory allergy are grasses, olive and parietaria. The knowledge of sensitizations to molecular allergens in children and adults can contribute to better diagnosis and treatment of this pathology. Methods ImmunoCAP singleplex technology was used for molecular allergens and Phadia 250® automatic equipment. g205 (Phl p1); g215 (Phl p5b); g210 (Phl p7...
Introdução: Os esporos de fungos como o Cladosporium e a Alternaria presentes em ambientes outdoor são responsáveis pelo desencadeamento de reações alérgicas. Assim sendo, o estudo aeromicológico de uma zona geográfica é importante. Objetivos: Identificar e quantificar os tipos de esporos de fungos presentes na atmosfera de Lisboa e analisar a influência dos fatores meteorológicos nas suas concentrações, de mod...
Introdução – Os esporos fúngicos são uma das maiores componentes biológicas atmosféricas; no entanto, são ainda pouco estudados e não lhes é reconhecida a influência devida na doença alérgica respiratória. Neste trabalho pretende-se determinar a importância dos níveis de esporos atmosféricos de Alternaria e Cladosporium na doença alérgica respiratória na cidade de Beja. Método – Analisaram-se os níveis atmosfér...
This study presents the findings of a 10-year survey carried out by the Portuguese Aerobiology Network (RPA) at seven pollen-monitoring stations: five mainland stations (Oporto, Coimbra, Lisbon, E´ vora and Portima˜o) and two insular stations [Funchal (Madeira archipelago) and Ponta Delgada (Azores archipelago)]. The main aim of the study was to examine spatial and temporal variations in the Annual Pollen Index...
Background: Ole e 1 is the major allergen of olive pollen (Olea europaea L.), the second largest cause of pollinosis in some areas from the Mediterranean Region. Although it has been assumed that airborne pollen is a representative parameter for allergen exposure, variability of allergen content and/or release from pollen has been demonstrated for other taxa. The aim of this study was to: i) estimate the correl...
