Molecular heterogeneity of Rhipicephalus sanguineus sensu lato and screening for Ehrlichia canis in mainland Portugal

  • Autores: Sanches GS, Couto J, Silva-Pedrosa R, Ferrolho J, Santos AS, Santos-Silva MM, Antunes S, Domingos A
  • Ano de Publicação: 2018
  • Journal: Ticks and Tick-Borne Diseases
  • Link: https://www.ncbi.nlm.nih.gov/pubmed/29958827

The present study aimed to expand knowledge regarding the molecular characterization of R. sanguineus s.l. in Portugal and to screen for ticks naturally infected with E. canis. A total of 113 R. sanguineus s.l. were collected questing or attached to domestic and wild animals from the 18 administrative regions of mainland Portugal. All the ticks […]

Rhipicephalus bursa sialotranscriptomic response to blood feeding and babesia ovis infection: Identification of candidate protective antigens

  • Autores: Antunes S, Couto J, Ferrolho J, Rodrigues F, Nobre J, Santos AS, Santos-Silva MM, de la Fuente J, Domingos A
  • Ano de Publicação: 2018

Abstract Ticks are among the most prevalent blood-feeding arthropods, and they act as vectors and reservoirs for numerous pathogens. Sialotranscriptomic characterizations of tick responses to blood feeding and pathogen infections can offer new insights into the molecular interplay occurring at the tick-host-pathogen interface. In the present study, we aimed to identify and characterize Rhipicephalus bursasalivary gland […]

PCR screening of tick-borne agents in sensitive conservation areas, Southeast Portugal

  • Autores: Antunes S, Domingos A, Duarte LR, Ferrolho J, Melo P, Milhano N, Santos AS, Santos N, Santos PT, Santos-Silva MM

The Southeast region of Portugal, particularly the Guadiana valley, is currently the reintroduction territory of Lynx pardinus (Iberian lynx), one of the most endangered felids in the world that is only found in the Iberian Peninsula. Over the last century, populations have declined, placing L. pardinus at extremely high risk of extinction in the wild and […]

Detection and phylogenetic characterization of Theileria spp. and Anaplasma marginale in Rhipicephalus bursa in Portugal

  • Autores: Antunes S, Cabezas-Cruz A, Domingos A, Ferrolho J, Padre L, Santos AS, Santos-Silva MM, Velez R
  • Ano de Publicação: 2016
  • Journal: Ticks and Tick-Borne Diseases

Ticks are obligatory blood-sucking arthropod (Acari:Ixodida) ectoparasites of domestic and wild animals as well as humans. The incidence of tick-borne diseases is rising worldwide, challenging our approach toward diagnosis, treatment and control options. Rhipicephalus bursa Canestrini and Fanzago, 1877, a two-host tick widely distributed in the Palearctic Mediterranean region, is considered a multi-host tick that […]

Anaplasma marginale and Theileria annulata in questing ticks from Portugal

  • Autores: Antunes S, Domingos A, Domingues N, Ferrolho J, Santos AS, Santos-Silva MM
  • Ano de Publicação: 2016
  • Journal: Experimental and Applied Acarology
  • Link: https://link.springer.com/article/10.1007%2Fs10493-016-0057-y

Ticks are ubiquitous arthropods and vectors of several pathogenic agents in animals and humans. Monitoring questing ticks is of great importance to ascertain the occurrence of pathogens and the potential vector species, offering an insight into the risk of disease transmission in a given area. In this study 428 host-seeking ticks, belonging to nine species of […]
