Analysis of clinical and environmental Candida parapsilosis isolates by microsa...
Sabino, Raquel; Sampaio, Paula; Rosado, Laura; Videira, Zélia; Grenouillet, Frederic; Pais, CéliaCandida parapsilosis emerged as an important opportunistic pathogen, causing candidaemia worldwide. Nosocomial outbreaks triggered by this species have been frequently described, particularly in cancer patients. For a better understanding of its epidemiology, several typing methods are used and microsatellite analysis has been reported as highly discriminant. The main objective of this work was to study C. para...
Diagnosis of Tinea pedis and onychomycosis in patients from Portuguese National...
Viegas, Carla; Sabino, Raquel; Parada, Helena; Brandão, João; Carolino, Elisabete; Rosado, Laura; Veríssimo, CristinaTinea 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 an analysis conducted during a four-year period on the frequency of Tinea pedis and onychomycosis and their etiologic agents. A question...

Identification of a fungal community on gilded wood carved heritage
Pinheiro, Ana Catarina; Brandão, João; Veríssimo, Cristina; Jurado, Valme; Rosado, Laura; Oliveira, Bruna; Macedo, Maria filomenaDuring restoration activities, a fungal reddish area was noted on a gilded wood carved ceiling decoration from a sacristy of a church in Aveiro, Portugal. The protocols used to identify the fungal community present in this wooden material included the classical culturing methods and a molecular biology protocol based on the ability of denaturing high performance liquid chromatography (DHPLC) to separate fungal ...

Estudo de comunidades fúngicas em arquivos: implicações na conservação e na saúde
Pinheiro, A. C.; Viegas, Carla; Jurado, V.; Sabino, Raquel; Veríssimo, Carlos; Rosado, Laura; Macedo, M. F.A influência da contaminação fúngica para a saúde ambiental e para a conservação do património é o tema premente e actual que suscitou a hipótese de estudo aqui apresentada. Os fungos, dada a sua extrema capacidade de adaptação, podem colonizar diversos materiais - orgânicos ou não - e a sua acção pode ser mecânica, por intermédio das suas hifas, ou química, através dos seus metabolitos. Em termos de conservaçã...
Isolates from hospital environments are the most virulent of the Candida paraps...
Sabino, Raquel; Sampaio, Paula; Carneiro, Catarina; Rosado, Laura; Pais, CéliaBackground: Candida parapsilosis is frequently isolated from hospital environments, like air and surfaces, and causes serious nosocomial infections. Molecular studies provided evidence of great genetic diversity within the C. parapsilosis species complex but, despite their growing importance as pathogens, little is known about their potential to cause disease, particularly their interactions with phagocytes. In...
Possible implications of a poultry fungal contamination
Viegas, Carla; Viegas, Susana; Veríssimo, C.; Rosado, Laura; Santos, Carlos SilvaBackground – Although there is an increasing industry that produces whole chickens for domestic consumption in Portugal, only a few investigations have reported on the indoor air of these plants and the consequences of their degradation. Objectives – Describe one poultry environmental fungal contamination and analyze possible associations between temperature and relative humidity and its possible impact on the ...
Risk assessment of exposure to multiple mycotoxins in food
Viegas, Susana; Viegas, Carla; Ramos, C.; Silva, M.; Sabino, Raquel; Veríssimo, C.; Rosado, LauraMoulds may produce a diversity of toxins such as aflatoxins, ochratoxins, trichothecenes, zearalenone, fumonisins and others. Although toxicological, environmental and epidemiological studies have addressed the problem of these toxins one by one, more than one mycotoxin are found usually in the same contaminated food. Risk assessment for humans potentially exposed to multimycotoxins suffers very much from the l...
