Trichophyton erinacei skin infection after recreational exposure to an elephant in Southeast Asia

Zoophilic fungal infections are a prevalent disease in tropical countries and clinicians must consider them in the differential diagnosis of pruritic skin lesions. We report a clinical case of Trichophyton erinacei skin infection after recreational exposure to an Asian Elephant. As far as we were able to search the literature, it is the first case described after contact with elephants.

Satellite-derived estimation of environmental suitability for malaria vector development in Portugal

This work focused on determining the current relationships between environmental factors and the density of the former malaria vector Anopheles atroparvus in Portugal, a previously endemic country. Adult females were sampled and vector density was estimated in 22 sites in Southern Portugal between 2001 and 2010 and related with land cover and satellite-derived air temperature and vegetation indices. The relationship between vector density and local larval habitat, temperature and, in a broader sense, to environmental suitability, was assessed using a statistical modelling approach.

Prevention and battle against obesity in children and youngsters at a strategic planning level and their evolution in Portugal

Considered by WHO as a global epidemic and one of the greatest public health challenges of the twenty‐first century, Obesity is a chronic disease with multiple causes, especially behavioural changes like dietary changes and sedentary lifestyle. It is a risk factor for other conditions, such as diabetes or cardiovascular diseases, associated with the decrease of life quality of individual and the increase of health costs.

Tick capillary feeding for the study of proteins involved in tick-pathogen interactions as potential antigens for the control of tick infestation and pathogen infection

Ticks represent a significant health risk to animals and humans due to the variety of pathogens they can transmit during feeding. The traditional use of chemicals to control ticks has serious drawbacks, including the selection of acaricide-resistant ticks and environmental contamination with chemical residues. Vaccination with the tick midgut antigen BM86 was shown to be a good alternative for cattle tick control. However, results vary considerably between tick species and geographic location.

Seasonal genetic partitioning in the neotropical malaria vector, Anopheles darlingi

Anopheles darlingi is the main malaria mosquito vector in the Amazonia region. In spite of being considered a riverine, forest-dwelling species, this mosquito is becoming more abundant in peri-urban areas, increasing malaria risk. This has been associated with human-driven environmental changes such as deforestation.
