First molecular identification of mosquito vectors of Dirofilaria immitis in continental Portugal

Background: Canine dirofilariasis due to Dirofilaria immitis is known to be endemic in continental Portugal. However, information about the transmitting mosquito species is still scarce, with only Culex theileri identified to date, albeit with L1-2, through dissection. This study was carried out to investigate the potential vectors of Dirofilaria spp. in continental Portugal. Methods: Mosquitoes […]

Bacterial and protozoal agents of feline vector-borne diseases in domestic and stray cats from southern Portugal

  • Autores: Bastos F, Campino L, Cardoso L, Coimbra M, Maia C, Martins A, Nunes M, Pinto P, Ramos C, Vieira ML
  • Ano de Publicação: 2014
  • Journal: Parasites & Vectors
  • Link: http://www.parasitesandvectors.com/content/7/1/115

Feline vector-borne diseases (FVBD) have emerged in recent years, showing a wider geographic distribution and increased global prevalence. In addition to their veterinary importance, domestic cats play a central role in the transmission cycles of some FVBD agents by acting as reservoirs and sentinels, a circumstance that requires a One Health approach. The aim of the present work was to molecularly detect feline vector-borne bacteria and protozoa with veterinary and zoonotic importance, and to assess associated risk factors in cats from southern Portugal.

Glossina palpalis palpalis populations from Equatorial Guinea belong to distinct allopatric clades

  • Autores: Bart J-M, Benito A, Cano J, Cordon-Obras C, Knapp J, Navarro M, Ndong-Mabale N, Ndongo-Asumu P, Nebreda P, Pinto J, Ricardo Ncogo-Ada P

Luba is one of the four historical foci of Human African Trypanosomiasis (HAT) on Bioko Island, in Equatorial Guinea. Although no human cases have been detected since 1995, T. b. gambiense was recently observed in the vector Glossina palpalis palpalis. The existence of cryptic species within this vector taxon has been previously suggested, although no data are available regarding the evolutionary history of tsetse flies populations in Bioko.

Tick capillary feeding for the study of proteins involved in tick-pathogen interactions as potential antigens for the control of tick infestation and pathogen infection

  • Autores: Alberdi P, Antunes S, Bell-Sakyi L, de la Fuente J, Domingos A, Fragkoudis R, Merino O, Moreno-Cid JA, Mosqueda J, Perez de la Lastra JM, Weisheit S

Ticks represent a significant health risk to animals and humans due to the variety of pathogens they can transmit during feeding. The traditional use of chemicals to control ticks has serious drawbacks, including the selection of acaricide-resistant ticks and environmental contamination with chemical residues. Vaccination with the tick midgut antigen BM86 was shown to be a good alternative for cattle tick control. However, results vary considerably between tick species and geographic location.
