First Detection of Borrelia burgdorferi sensu lato DNA in Serum of the Wild Boar (Sus scrofa) in Northern Portugal by Nested-PCR

Lyme borreliosis is the most common tick-borne zoonosis in the northern hemisphere. Several vertebrates are crucial in the epidemiological cycle of Borrelia burgdorferi sensu lato, but the role of wild boar as a reservoir is still unknown. Sera were collected from 90 wild boars shot in the Trás-os-Montes region, Northern Portugal (hunting season 2011/2012). In […]

The recent Ebola Virus Outbreak had a devastating effect on West Africa’s already feeble national health systems. We suggest that such an impact turned out to be catastrophic because it hit particularly hard human resources for health and the delivery of primary healthcare services, which are cross-sectional to any health system. National and international interventions […]

Transcriptomic analysis of Anopheles stephensis salivary glands

Malaria disease have a great impact in social health, and for this reason the interactions between the malarial parasite and the mosquito vector can be ellucidated by different methods including transcriptomics. RNA-seq is a new approach that by a comparison of the transcriptome of a organism in different conditions, can provide a catalogue of differentially […]

The role of regulatory CD4+CD25+ T cell subset in host homeostasis during protozoan infection

Human diseases caused by protozoan parasites are renowned for their high rates of morbidity and mortality worldwide. Some examples include African trypanosomiasis or sleeping sickness, American trypanosomiasis or Chagas disease, leishmaniases, malaria and babesiosis. These infections tend to follow a chronic rather than an acute course with lifelong persistence of parasites. Regulatory T cells (Treg), in […]
