Portuguese hosts for Ornithodoros erraticus ticks

The hematophagous soft tick Ornithodoros erraticus feeds nocturnally on multiple warm-blooded vertebrate hosts. This tick is often found living buried in the soil of traditional pigpens. O. erraticus is an important infectious disease vector both for humans and animals. In the Iberian Peninsula, this tick serves as the vector of human tick-borne relapsing fever caused by the spirochete Borrelia hispanica. The n...

Screening of mosquitoes as vectores of F. tularensis in Portugal

Background: Francisella tularensis subsp. holartica is the etiologic agent of type B tularemia, an emergent zoonosis that occurred recently in Portugal´s neighboring country Spain, where there was an outbreak in 2007.(1) This fact has propelled the research of this pathogen in Portugal. Mosquitoes Culex spp. and Aedes spp. are considered important vectors of the pathogen in Sweden(2) but in Portugal the presenc...

Mosquito species distribution in mainland Portugal 2005-2008

Information on distribution and relative abundance of the mosquito fauna of mainland Portugal has been collected by several surveillance programmes and projects over a long period. The work presented here documents additional information provided by capture of adult mosquitoes by the use of CDC light traps baited with CO2 in 48 localities in 13 districts in different parts of mainland Portugal during the period...

Genome diversity in the genera Fructobacillus, Leuconostoc and Weissella determ...

Pulsed-field gel electrophoresis analysis of chromosomal single and double restriction profiles of 17 strains belonging to three genera of ‘Leuconostocaceae’ was done, resulting in physical and genetic maps for three Fructobacillus, six Leuconostoc and four Weissella strains. AscI, I-CeuI, NotI and SfiI restriction enzymes were used together with Southern hybridization of selected probes to provide an assessmen...
