Campylobacter spp. are a leading cause of human diarrhea. The common source of infection is contaminated food, particularly poultry. From May 2005 to October 2006, 164 samples of poultry obtained from several retail establishments and from different Portuguese producers were analyzed for the presence of Campylobacter spp. A total of 99 Campylobacter strains(More)
Invasive in many European countries, the American mink (Neovison vison) was introduced in Portugal in the late 1980’s, presumably escaping from Spanish fur farms close to the border. In spite of the biological richness of the invaded area, no study ever addressed the evolution of the invasion process. We aimed to investigate the current distribution and(More)
The correct modelling of the potential distribution of an invasive species is crucial to define effective management and monitoring strategies. Here we compared the results of models built at different spatial scales to identify the areas at risk of invasion by the red swamp crayfish (Procambarus clarkii) in the northwest of Portugal. Firstly, we surveyed(More)
Infective endocarditis despite advances in diagnosis remains a common cause of hospitalization, with high morbidity and mortality rates. Through literature review it is possible to conclude that polymicrobial endocarditis occurs mainly in intravenous drug abusers with predominance in the right side of the heart, often with tricuspid valve involvement.

The former Instituto de Investigação Científica Tropical-IICT (Lisbon, Portugal), recently integrated into the University of Lisbon, gathers important natural history collections from Portuguese-speaking African countries. In this study, we describe the bird collection from the Democratic Republic of São Tomé and Príncipe, which was fully taxonomically(More)
The bird collection of the Instituto de Investigação Cientítica Tropical (Lisbon, Portugal) holds 5598 preserved specimens (skins), mainly from Angola, Mozambique, Guinea-Bissau, São Tomé and Principe, and Cape Verde. The subset collection from Angola includes 1560 specimens, which were taxonomically revised and georeferenced for the publication of this(More)
The complexity and diversity of physical and biotic habitats are important features influencing the composition of shallow water reef fish assemblages, especially in temperate regions where abundant and diverse algal cover may have an important habitat-forming role. Coastal fish have adapted to these diverse habitats and to the temporal and spatial(More)
