Hepatitis C virus subtypes circulating among intravenous drug users in Lisbon, Portugal.

  • Autores: Calado RA, Esteves A, Parreira R, Piedade J, Rocha MR, Venenno T
  • Ano de Publicação: 2011
  • Journal: Journal of Medical Virology
  • Link: http://www.ncbi.nlm.nih.gov/pubmed/?term=Hepatitis+C+virus+subtypes+circulating+among+intravenous+drug+users+in+Lisbon%2C+Portugal

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).

Genetic characterization of an insect-specific flavivirus isolated from Culex theileri mosquitoes collected in southern Portugal.

  • Autores: Cook S, de Almeida AP, de Matos AP, Esteves A, Lopes A, Parreira R, Piedade J
  • Ano de Publicação: 2012
  • Journal: Virus Research
  • Link: http://www.ncbi.nlm.nih.gov/pubmed/?term=Genetic+characterization+of+an+insect-specific+flavivirus+isolated+from+Culex+theileri+mosquitoes+collected+in+southern+Portugal

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.

Echinococcus granulosus in Portugal: The first report of the G7 genotype in cattle

  • Autores: Beato S, Cringoli G, Gonçalves M, Grácio MA, Maurelli MP, Parreira R, Roque C, Silva L
  • Ano de Publicação: 2013
  • Journal: Veterinary Parasitology
  • Link: http://www.ncbi.nlm.nih.gov/pubmed/24035548

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.

Intestinal parasites in dogs and cats from the district of Évora, Portugal.

  • Autores: Atouguia J, Centeno-Lima S, Ferreira FS, Padre L, Parreira R, Pereira-Baltasar P, Távora Tavira L, Vilhena M
  • Ano de Publicação: 2011
  • Journal: Veterinary Parasitology
  • Link: http://www.ncbi.nlm.nih.gov/pubmed/?term=Intestinal+parasites+in+dogs+and+cats+from+the+district+of+%C3%89vora%2C+Portugal

Intestinal parasites, both helminths and protozoa, are commonly found in domestic animals, and the possible transmission of enteric parasites from dogs and cats to humans may constitute a global potential health risk worldwide.

Dengue fever in Europe: could there be an epidemic in the future?

  • Autores: Parreira R, Sousa CA
  • Ano de Publicação: 2015
  • Journal: Infective Therapy
  • Link: http://www.ncbi.nlm.nih.gov/pubmed/25399556

Dengue virus (DENV) is the arbovirus with the widest impact on human health. Although its dispersal is partially conditioned by environmental constraints that limit the distribution of its main vector (Aedes aegypti), DENV has been spreading geographically in recent times, but mostly afflicting tropical and subtropical regions.

Molecular Identification of Borrelia miyamotoi in Ixodes ricinus from Portugal

  • Autores: Campino L, Carreira T, Faria S, Lopes N, Maia C, Nunes M, Parreira R, Sousa C, Vieira ML
  • Ano de Publicação: 2015
  • Journal: Vector-Borne and Zoonotic Diseases
  • Link: http://www.ncbi.nlm.nih.gov/pubmed/26273814

Borrelia miyamotoi, a relapsing fever spirochete, has been found recently in Ixodes ricinus ticks; however, little is known about its spatial distribution and potential local impact on human health.

Molecular detection of Leishmania DNA and identification of blood meals in wild caught phlebotomine sand flies (Diptera: Psychodidae) from southern Portugal

Exploring the utility of phylogenetic analysis of cytochrome oxidase gene subunit I as a complementary tool to classical taxonomical identification of phlebotomine sand fly species (Diptera, Psychodidae) from southern Europe

  • Autores: Afonso MO, Campino L, Cristovao JM, Maia C, Parreira R
  • Ano de Publicação: 2015
  • Journal: Acta Tropica
  • Link: http://www.ncbi.nlm.nih.gov/pubmed/25617635

Phlebotomine sand flies (Diptera, Psychodidae) are known to be vectors of several pathogens such as Leishmania and Phlebovirus genera. The identification of phlebotomine sand fly species is currently based on morphological characters, and requires considerable taxonomic expertise and skilfulness, but may be complemented by DNA-based analyses for (i) accurate species identification and (ii) for estimating sand fly diversity.

Negeviruses found in multiple species of mosquitoes from southern Portugal: Isolation, genetic diversity, and replication in insect cell culture

  • Autores: Abecasis A, Carapeta S, de Almeida APG, de Matos AP, do Bem B, Esteves A, Lopes A, McGuinness J, Parreira R, Piedade J
  • Ano de Publicação: 2015
  • Journal: Virology
  • Link: http://www.ncbi.nlm.nih.gov/pubmed/26057025

In this report, an RT-PCR approach based on the use of degenerate primers allowed the identification of negeviruses in four different species of mosquitoes (Ochlerotatus caspius, Culex pipiens, Cx. theileri and Cx. univittatus) collected in southern Portugal. The genomes of two of these viruses, sequenced to full completion, were shown to encode all the proteins encoded by previously described negeviruses

Angola’s 2013 dengue outbreak: clinical, laboratory and molecular analyses of cases from four Portuguese institutions

  • Autores: Abreu C, Antunes A, Atouguia J, Azevedo T, Centeno-Lima S, Conceicao C, da Cunha JS, Mansinho K, Marques N, Moneti V, Nazareth T, Nina J, Parreira R, Sa L, Sarmento A, Seixas J, Teodósio R
  • Ano de Publicação: 2014
  • Journal: The Journal of Infection in Developing Countries
  • Link: http://www.ncbi.nlm.nih.gov/pubmed/25212088

Dengue virus (DENV) is the arbovirus with the widest impact on human health. In Africa in general, and in Angola in particular, the epidemiology and public health impact of DENV is far from clear. However, rapid population growth, unplanned urbanization, increased international travel, and the presence of virus major vector (Aedes aegypti) in the country suggest that DENV transmission may occur.
