Infection by the larval stage of the cestode Echinococcus granulosus causes a disease known as cystic echinococcosis or hydatidosis, which is one of the most widespread zoonotic infections of veterinary and medical importance.

Hepatitis C virus (HCV) infects 2-3% of the world population and intravenous drug consumption is the leading cause of transmission in industrialized countries. The unavailability of data on the molecular epidemiology of HCV infection in Portugal prompted the study of HCV subtypes circulating among intravenous drug users residing in the Lisbon metropolitan area and sampled about 10 years apart (1998-2000 and 2008-2009).

We describe the full genetic characterization of an insect-specific flavivirus (ISF) from Culex theileri (Theobald) mosquitoes collected in Portugal. This represents the first isolation and full characterization of an ISF from Portuguese mosquitoes. The virus, designated CTFV, for Culex theileri flavivirus, was isolated in the C6/36 Stegomyia albopicta (=Aedes albopictus) cell line, and failed to replicate in vertebrate (Vero) cells in common with other ISFs.

Although cystic echinococcosis (CE) has been a recognized public health problem in Portugal, molecular data regarding the types and prevalence of infecting strains of its etiological agent (Echinococcus granulosus) are still scarce. Over the last years we have been evaluating the prevalence of CE in the country, and in this report we determined the parasite genotypes infecting sheep, goats, cattle and human in Portugal.
