Vivir con Chagas en Madrid: estructuras temporales de la vivencia de un grupo de pacientes bolivianos con el diagnóstico y la atención médica a la enfermedad de Chagas en un hospital metropolitano español

How can a chronic disease determine the life of a group of people diagnosed as seropositive away from their home country? And how do we account for that lived experience. Some diseases contemplated a few decades ago as strictly rural or of poor countries, are an urban reality now and are part of the epidemiological setting in wealthy developed countries. That is the case of Chagas disease in Spain. A disease linked for a long time to rural poverty, until migratory movements occurred nationwide from the country side to the city, and recently with international migration have turned pathology into a global public health issue. Chagas disease is a chronic parasitic infection, endemic in all Latin America and can be transmitted by triatomine or “kissing bug” (Triatoma Infestans), which lives and reproduces in straw houses of rural regions. According to the Pan American Health Organization (PAHO, 2006), the disease affects approximately eight million people. It is recognized by the WHO as a “neglected tropical disease”...

Metagenomic detection of viral pathogens in Spanish honeybees: co-infection by Aphid Lethal Paralysis, Israel Acute Paralysis and Lake Sinai Viruses

The situation in Europe concerning honeybees has in recent years become increasingly aggravated with steady decline in populations and/or catastrophic winter losses. This has largely been attributed to the occurrence of a variety of known and "unknown", emerging novel diseases. Previous studies have demonstrated that colonies often can harbour more than one pathogen, making identification of etiological agents with classical methods difficult. By employing an unbiased metagenomic approach, which allows the detection of both unexpected and previously unknown infectious agents, the detection of three viruses, Aphid Lethal Paralysis Virus (ALPV), Israel Acute Paralysis Virus (IAPV), and Lake Sinai Virus (LSV), in honeybees from Spain is reported in this article. The existence of a subgroup of ALPV with the ability to infect bees was only recently reported and this is the first identification of such a strain in Europe. Similarly, LSV appear to be a still unclassified group of viruses with unclear impact on colony health and these viruses have not previously been identified outside of the United States. Furthermore, our study also reveals that these bees carried a plant virus, Turnip Ringspot Virus (TuRSV), potentially serving as important vector organisms. Taken together, these results demonstrate the new possibilities opened up by high-throughput sequencing and metagenomic analysis to study emerging new diseases in domestic and wild animal populations, including honeybees.
