Cystoseira is a common brown algal genus widely distributed throughout the Atlantic and Mediterranean regions whose taxonomical assignment of specimens is often hampered by intra- and interspecific morphological variability. In this study, three mitochondrial regions, namely cytochrome oxidase subunit 1 (COI), 23S rDNA (23S), and 23S-tRNAVal intergenic spacer (mt-spacer) were used to analyse the phylogenetic […]

Molecular detection of bacterial and parasitic pathogens in hard ticks from Portugal

  • Autores: Campino L, Cardoso L, Ferreira A, Maia C, Nunes M, Vieira ML
  • Ano de Publicação: 2014
  • Journal: Ticks and Tick-Borne Diseases
  • Link: http://www.ncbi.nlm.nih.gov/pubmed/24745731

Ticks are important vector arthropods of human and animal pathogens. As information about agents of disease circulating in vectors in Portugal is limited, the aim of the present study was to detect bacteria and parasites with veterinary and zoonotic importance in ticks collected from dogs, cats, and field vegetation. A total of 925 ticks, comprising 888 (96.0%) adults, 8 (0.9%) nymphs, and 29 (3.1%) larvae, were collected in 4 geographic areas (districts) of Portugal.
